Lithium battery is a commonly used rechargeable battery, which is mainly composed of lithium battery cells. The lithium battery cell is the most important component of the lithium battery. It is responsible for storing and releasing electrical energy and is the "heart" of the battery. It has several advantages over other types of batteries. Lithium batteries have high energy density. Energy density refers to the energy stored per unit mass or volume of a battery. In comparison, the energy density of lithium batteries is much higher than other types of batteries, such as nickel-cadmium batteries and lead-acid batteries. This means that lithium batteries can store more energy, allowing electronic devices to work longer, be more portable, and reduce the frequency of battery replacement. Lithium batteries have a low self-discharge rate. Self-discharge rate refers to the rate at which a battery discharges itself when in storage or idle. Lithium batteries have a lower self-discharge rate compared to nickel-metal hydride and nickel-cadmium batteries. This is useful for spare batteries or equipment that is used infrequently, as they can be kept in a shed or warehouse for long periods of time without the need for regular charging. Lithium batteries have a long life. Lithium batteries have a longer service life than other types of batteries. Lithium batteries are ideal for devices that are used for long periods of time and recharged repeatedly, such as electric vehicles and wearable devices. Lithium batteries have the characteristics of rapid charging and discharging. Lithium batteries charge and discharge faster than other types of batteries, such as nickel-metal hydride batteries. It is especially important for those who need to use their devices frequently, as it can shorten charging time and increase work efficiency. In addition to the above-mentioned advantages, there are also lower weight and lower pollution and environmental impact. Lithium battery cells can be combined into lithium-ion battery packs of various forms and capacities. Common battery pack forms are series and parallel. Series connection is to connect multiple lithium battery cells together according to a certain voltage connection method, so that the voltage is accumulated; parallel connection is to connect multiple lithium battery cells together according to a certain current connection method, so that the current is accumulated.

User-side energy storage mainly includes industrial and commercial energy storage and household energy storage. At present, the cost of household energy storage is more than 0.6 yuan / kWh, the domestic residential electricity price is low and the peak-valley price difference is also low, and the main customers and markets are in Europe, North America, Australia and other overseas regions with high residential electricity prices. Industrial and commercial energy storage systems are above 0.7 yuan / kWh, mainly used in places where electricity prices are higher and peak-valley price differences are also high, the market is widely used, and the schemes are also diverse, which can be selected according to application scenarios. From the structural point of view, energy storage products include containers or prefabricated cabins, outdoor cabinets or indoor cabinets; According to the cooling mode, there are two types: air cooling and liquid cooling; According to the classification of electrical structure, there are two types: centralized and string; According to the classification of energy storage systems, there are two types: equipment and battery split and equipment and battery integrated, according to voltage level, there are two types: 1000V system and 1500V system; There are two types of energy collection points: DC coupling and AC coupling. Large/medium-sized energy storage products, currently based on the structure of containers or prefabricated cabins, are generally used on the power supply side and the power grid side, a small number of applications are on the user side, the cooling mode gradually transitions from air cooling to liquid cooling, the electrical structure is mainly centralized, string energy storage is also gradually added, the voltage is gradually based on 1500V, and the AC coupling method is the mainstay. The income model of energy storage on the industrial and commercial user side is peak-valley arbitrage, full of release; The more charge and discharge volume, the greater the benefit; The higher the energy conversion efficiency, the smaller the loss and the greater the benefit. Therefore, the user-side energy storage system equipment with string cluster-controlled energy storage integrated system has a higher yield than the centralized energy storage integrated system. The effective utilization rate of each cluster of clustered energy storage system is high, and there is no barrel short board effect; There is no parallel connection between clusters, no circulation, and high energy conversion efficiency. Due to the decentralized layout, distributed small energy storage cabinets consider the high after-sales cost of maintenance; The demand purchase volume is small, so the unit price of related components and the overall system is higher. At present, the market price of small energy storage outdoor cabinets is estimated to be about 1.8 yuan / Wh. The price of centralized energy storage system is 1.3‒1.5 yuan/Wh (tens of MWh purchase). DC coupling As shown in the figure below, the direct current generated by the photovoltaic modules is stored in the battery pack through the controller, and the grid can also charge the battery through the bidirectional DC-AC converter. The energy pooling point is at the DC battery end. The working principle of DC coupling: when the photovoltaic system is running, the battery is charged through the MPPT controller; When the electrical load is demanded, the battery will release the power, and the size of the current is determined by the load. The energy storage system is connected to the grid, and if the load is small and the battery is full, the photovoltaic system can supply power to the grid. When the load power is greater than the photovoltaic power generation, the grid and the photovoltaic can supply power to the load at the same time. Because photovoltaic power generation and load power consumption are not stable, it depends on the battery to balance the system energy. AC coupling The direct current generated by the photovoltaic modules is changed into alternating current through the inverter, directly to the load or sent to the grid, and the power grid can also charge the battery through the bidirectional DC-AC bidirectional converter. The gathering point of energy is at the AC end. The working principle of AC coupling: including photovoltaic power supply system and battery power supply system. The photovoltaic system consists of a photovoltaic array and a grid-connected inverter; The battery system consists of a battery pack and a bidirectional inverter. The two systems can operate independently without interfering with each other, or they can be separated from the large grid to form a microgrid system. From the currently installed cases, user-side energy storage using modular, string, AC-side coupling scheme has become a trend, occupying more than 80% of the market share, this scheme has low cost, flexible configuration, high safety, suitable for industrial and commercial and off-grid energy storage power stations, and DC-side coupling centralized scheme, simple wiring, stable system, suitable for small and medium-sized independent power stations. www.ufobattery.com

Selecting the right kWh capacity for your home battery can be a challenging task, as it depends on various factors, including your home`s energy consumption, renewable energy production, and the desired level of energy independence. In this blog post, we will provide a comprehensive guide on how to choose the right kWh capacity for your home battery system. Assess Your Energy Consumption The first step in determining the appropriate kWh capacity for your home battery is to assess your energy consumption. You can do this by reviewing your monthly electricity bills to determine your average daily kWh usage. Alternatively, you can use an energy monitoring system to gain real-time insights into your energy consumption patterns. Consider Your Renewable Energy Production If you have solar panels or wind turbines installed at your home, you will need to consider the amount of energy they produce. The kWh capacity of your home battery should be large enough to store excess energy generated by your renewable energy system, which can be used when production is low or during peak demand hours. Determine Your Desired Level of Energy Independence Your desired level of energy independence plays a critical role in determining the kWh capacity of your home battery. If you aim to be fully off-grid, you will need a larger battery capacity to store energy for multiple days. On the other hand, if your goal is to have backup power during outages or peak demand hours, a smaller battery capacity may suffice. Evaluate Battery Technologies and Costs Different battery technologies have varying costs, energy densities, and discharge rates. When choosing the kWh capacity for your home battery, you need to strike a balance between cost and performance. Generally, larger battery capacities will be more expensive, so you must weigh the benefits of increased energy independence against the financial investment. There is no one-size-fits-all answer to the question of what kWh capacity to choose for a home battery solution, It ultimately depends on your individual energy consumption patterns, renewable energy production, and desired level of energy independence. By carefully assessing these factors and evaluating the available battery technologies and costs, you can make an informed decision that best suits your unique needs and preferences.

According to the incomplete statistics of the global energy storage project database of ZHONGguancun Energy Storage Industry Technology Alliance (CNESA), by the end of 2021, the cumulative installed capacity of new energy storage projects in China is 5.7GW, and the newly installed capacity is 2.4GW, with a year-on-year growth of 54%, among which the newly installed capacity on the power side is up to 1GW. The second is the new installed capacity of the power grid reached 854MW. During the 14th Five-year Period, the National Energy Administration put forward a development goal of no less than 30GW in the Guiding Opinions on Promoting the Development of New Energy Storage. If this goal is realized, the new energy storage will increase by at least 10 times. The market is growing at a high speed, but the road of development of new energy storage is still bumpy. Whether the energy storage power station can be reasonably invoked, whether it can obtain reasonable income through the market, and whether the income can be guaranteed stably have been the main problems that have troubled the development of new energy storage. The market urgently needs to straighten out the policy mechanism, price mechanism and scheduling operation mechanism for new energy storage to participate in market operation. In this context, the release of "Notice on Further Promoting the Participation of New energy storage in the power market and dispatching Application" can be said to be a timely rain for the energy storage market and solve the long-expected problem of the industry. The following is our interpretation of the key content of the Notice. I. Adhere to the principle of market-oriented development, define the independent energy storage identity for the first time. In the general requirements of "notice" is put forward to build a perfect adaptation of energy storage in market mechanism, encourage new energy storage choose to participate in power market, adhere to market-oriented way form the price, continue to improve the operating mechanism of scheduling giving full play to the advantages of energy storage technology, enhance the level of energy storage in general use, safeguard energy storage reasonable income, promote the healthy development of the industry. Firmly clarified the fundamental principle of market-oriented development. Notice at the same time, the first official definition for independent storage: measurement, control and other technical conditions, independently access can be power grid dispatching automation system monitoring and scheduling, comply with relevant standards and in compliance with the relevant aspects of electricity market operation mechanism and so on, has the legal personality of the new type of energy storage project, to be converted into independent energy storage, as an independent subject to participate in the electricity market. Throughout the development of domestic and foreign energy storage market in the past two years, independent energy storage is a development mode that attracts more attention. The United States, Australia, such as the UK are the ground level of implementation of a batch of hundred megawatts of energy storage projects independently, in our country in shandong, hunan, jiangsu, hebei, shanxi, zhejiang, anhui and other places are in the layout of large-scale energy storage projects independently, covers the lithium ion battery technology category, compressed air energy storage, flow batteries, flywheel energy storage, and other technical route. This year, shandong independent energy storage demonstration project has entered the spot market operation, a new stage of China's new energy storage development. Compared with the previous energy storage projects jointly operated by the power generation side, new energy and thermal power plants and the user-side energy storage projects, independent energy storage has the natural conditions to participate in the market as an independent subject in terms of technology and form. In terms of function, independent energy storage can provide flexibility for the system and safety support for power grid operation more efficiently. In terms of income, independent energy storage has the ability to obtain multiple benefits by participating in transactions between different varieties in multiple markets. Therefore, the notice clearly defines the identity of independent energy storage, which is an important basis for promoting the participation of new energy storage in the market. Promote the synergistic development of renewable energy and energy storage by encouraging participation in the market. Since 2019, a total of 22 provinces and cities across The country have introduced policies on the allocation of renewable energy storage. Currently, the number of new energy storage projects planned by provinces across the country has reached 42GW. The reason behind the policy of energy storage allocation of renewable energy actively promoted by provinces reflects that under the background of the rapid increase of the penetration rate of renewable energy, the system regulation pressure of power grid keeps increasing and the demand for flexible resources keeps increasing, so new regulation resources need to be built to relieve the pressure. Strong, however, with the rapid development of the energy storage policy in creating new energy storage, at the same time, is accompanied by a large number of new energy storage because there is no reasonable planning, reasonable calls in the idle state, and once appear the phenomenon of "bad money drive out good money", and behind it is the core issue of renewable energy configuration energy storage could not participate in the market, the lack of reasonable cost dredge the channel, The role and value of energy storage is difficult to play and gain benefits. According to the Notice, new energy storage projects existing in the form of allocation are encouraged to participate in the power market in accordance with existing relevant rules by combining with other types of power supply as a whole, provided that the transformation of metering and control systems within the station is completed and relevant technical requirements are met. Around the advancement of electric power market construction, so as to operations PeiJian storage facilities, the new energy will be able to improve the operations of the new energy for network performance to reduce examination, and can be jointly participate in the spot market, ancillary services market, mid-term and long-term market, improve operations in the new energy power, and can provide new energy terminal capacity value, in order to obtain a higher price. In addition, it is also mentioned in the Notice that with the gradual maturity of market construction, it is encouraged to explore a market model in which the same energy storage entity can participate in the market in two ways: independent capacity and joint capacity. This model is put forward, which makes the same subject can need according to the different functions of energy storage power station, the capacity of partition management involved in different markets, get more value returns, this will inspire all kinds of main body in technology, application, market model on continuous innovation, expand the existing in our country new energy storage business models, inspired the imagination of the market. Of course, if you want to really fall into the technical level, measurement and settlement, market mechanism, there are still many key problems to be solved. 3. Solve the problem of independent energy storage price and solve the key problems of entering the market. The Circular proposed to accelerate the participation of independent energy storage in the medium and long term market and spot market, and play the role of peak shifting and valley filling and peak power generation. If an independent energy storage station transmits electricity to the power grid, its corresponding charging power shall not bear the electricity price of transmission and distribution, governmental funds and additional charges. This a policy actually solves the problem of independent storage to participate in the market the most key, has long been a new energy storage due to its bidirectional regulation, to clear their identity to participate in the market, the provinces in the independent storage related policy, on energy storage or ignored the charge and discharge of electricity price, or to "put a set-off, loss since the bear" to encourage energy storage construction, But policies are not long-term and stable. Independent energy storage in the process of the charge and discharge played a peak shift and the peak power, if charged, according to charge power users, when the discharge in accordance with the power to give prices, will face repeated charge distribution electricity and government-managed funds and additional problems, at the same time in lithium ion batteries, for example, inflation was from 10% to 20% of the electricity will be loss, It will be difficult for independent energy storage to make money by participating in the electricity market. Taking Shandong market as an example, if the electricity charged does not bear the electricity transmission and distribution price and the government funds and additional, the electricity price cost of about 0.2 yuan can be reduced, which is a great benefit for the independent energy storage power station to participate in the market transaction! 4. Optimize the energy storage scheduling operation mechanism to ensure fair invocation. The Circular proposes to adhere to the market-oriented approach to optimize the scheduling operation of energy storage, local governments should establish and improve the market mechanism and scheduling operation mechanism adapted to the development of new energy storage, and put forward technical requirements for energy storage project owners, power trading institutions and power enterprises, and clarify the management responsibilities of all parties. At the same time, relevant departments of local governments and dispatched agencies of the National Energy Administration are required to study and refine regulatory measures, strengthen supervision over independent energy storage dispatching and operation, and ensure that the energy storage power stations invested by social capital are operated fairly, with equal rights and utilization rates. For a long time, when social capital invests in the construction of independent energy storage power stations, whether the power station can be used fairly and reasonably is the most important issue for investors, which is directly related to the income and operation mode of the power station. It is clearly stated in the Notice that the energy storage power stations invested by social capital are guaranteed fair dispatching, equal rights and utilization rate, which is conducive to creating a fair and competitive market environment for the development of new energy storage and ensuring reasonable income of energy storage power stations. 5. Improve the price mechanism and reasonably guide the cost of energy storage. As a new member of the power system, the most critical issue for new energy storage to participate in the market is how to obtain benefits from its role value and how to share the benefits through reasonable channels. "Notice" proposed to give full play to the advantages of independent energy storage technology to provide auxiliary services. It is clear that the auxiliary service fees shall be reasonably shared by the grid-connected subjects and power users on the relevant power generation side according to the relevant provisions of the Administrative Measures for Electric Power Auxiliary Services and the principle of "who provides, who gains, who benefits and who bears". Put forward the establishment of grid-side energy storage price mechanism, study the establishment of grid-side independent energy storage power station capacity price mechanism, and gradually promote the power station to participate in the power market; Explore how to include the cost and income of power grid alternative energy storage facilities into the recovery of power transmission and distribution price. By improving the electricity price mechanism, independent energy storage will get corresponding compensation through participation in the auxiliary service market and electricity and energy benefits through the spot market, and its capacity value will get stable benefits through the capacity electricity price, which will guarantee the reasonable income of independent energy storage power stations and truly release the market space. At the same time, the circular stressed that all localities should strengthen scientific planning and effective supervision of power grid side energy storage. Effective supervision and reasonable incentives are the constraints on the capacity price of independent energy storage power stations on the grid side, and also the means to ensure the healthy and orderly development of the market. In addition, the notice also puts forward requirements for user-side energy storage, management of new energy storage projects, and safety management of electrochemical energy storage power stations. The introduction of the Notice is to promote the full participation of new energy storage in the market, and its efforts to break the market mechanism barriers and solve key problems highlight the determination of the government authorities to promote the development of new energy storage! We believe that with the continuous improvement of market mechanism and the continuous development and maturity of technology, new energy storage will surely shoulder the great task of realizing the "double carbon" goal, and China will surely become the largest market leading the development of energy storage in the world!

In order to further clear the new energy storage market orientation, set up perfect market mechanism, price mechanism and operational mechanism, enhance the level of new energy storage using and guide the healthy development of industry, the National Development and Reform Commission, the state energy bureau recently issued by the "about further promoting new energy storage in electric power market and operation notice (hereinafter referred to as the" notice "), It proposes to accelerate the participation of independent energy storage in the mid - and long-term market and spot market. If an independent energy storage station transmits electricity to the power grid, its corresponding charging power shall not bear the electricity price of transmission and distribution, governmental funds and additional charges. According to the introduction, the new energy storage has the advantages of quick response, flexible configuration and short construction period. It can play a variety of roles in power operation, such as peak, peak, frequency modulation, climbing, black start and so on, and is an important part of the construction of a new power system. It is necessary to establish and improve the market mechanism suitable for energy storage participation, encourage new energy storage to participate in the power market independently, adhere to the market-oriented pricing, continue to improve the dispatching operation mechanism, give full play to the advantages of energy storage technology, improve the overall utilization level of energy storage, ensure reasonable returns of energy storage, and promote the healthy development of the industry. As required, new energy storage can participate in the power market as independent energy storage. New energy storage projects with legal personality can be converted to independent energy storage and participate in the power market as an independent subject if they have the technical conditions of independent metering and control, access to the dispatching automation system can be monitored and dispatched by the power grid, and meet the requirements of relevant standards and specifications and power market operation institutions. Encourage new energy storage projects existing in the form of auxiliary construction. When the same technical conditions and safety standards are met through technical transformation, they can choose to become independent energy storage projects. According to the relevant requirements of the Guiding Opinions of the National Development and Reform Commission and the National Energy Administration on Promoting the Integration of Charge and Storage of Power Source Network and the Development of Multi-energy Complementarity, the energy storage of the multi-energy complementarity integration project involving scenery, water and fire storage will not be converted to independent energy storage temporarily in principle. The Circular encourages the installation of new energy storage and the joint participation of their power sources in the electricity market. New energy storage projects existing in the form of allocation are encouraged to participate in the power market in accordance with existing relevant rules by combining with other types of power supply as a whole, provided that the transformation of metering and control systems within the station is completed and relevant technical requirements are met. According to the actual situation of power supply liberalization in the market, new energy stations and allocated energy storage are encouraged to participate in the market jointly, so as to use energy storage to improve the performance of new energy grid and ensure the efficient consumption and utilization of new energy. With the gradual maturity of market construction, it is encouraged to explore a market model in which the same energy storage entity can participate in both independent and joint capacity. It is worth noting that the circular calls for accelerating the participation of independent energy storage in the power market in conjunction with peak regulation of the grid. Accelerate the participation of independent energy storage in the medium - and long-term market and spot market. In view of the relatively small energy storage capacity at the present stage, independent energy storage is encouraged to sign peak and trough market contracts to play the role of peak shifting and valley filling and peak power generation. If an independent energy storage station transmits electricity to the power grid, its corresponding charging power shall not bear the electricity price of transmission and distribution, governmental funds and additional charges. To give full play to the advantages of independent energy storage technology to provide auxiliary services. Independent energy storage is encouraged to provide auxiliary services such as active power balancing service, reactive power balancing service and accident emergency and recovery service, as well as rapid active power response service in case of power grid accident, in accordance with auxiliary service market rules or auxiliary service management rules. Auxiliary service fees shall be reasonably shared by the grid-connected subjects and power users on the relevant generating side according to the relevant provisions of the Administrative Measures for Electric Auxiliary Services and the principle of "who provides, who gains, who benefits and who bears". In terms of energy storage scheduling operation mechanism, the Circular requires that energy storage scheduling operation be optimized mainly in a market-oriented way. For the allocated energy storage that is not involved in the market, especially the allocated energy storage of new energy, the power dispatching institution should establish a scientific dispatching mechanism, and the project owner should strengthen the operation and maintenance of the energy storage facility system to ensure the safe and stable operation of the energy storage system. For energy storage of coal-fired power generation and other types of power supply, refer to the above requirements to further improve energy storage utilization level. At the same time, it further supports the development of user-side energy storage. According to the actual situation of power supply and demand, the peak-valley price difference should be appropriately widened to create space for the development of user-side energy storage. According to the actual situation of each region, it is encouraged to further increase the upper and lower prices of medium and long term power market and spot market, guide users to proactively configure new energy storage, and increase the revenue channels of energy storage on the user side. Users are encouraged to use energy storage technology to reduce their own peak power demand and reduce the capacity expansion investment of access power system. In addition, the power grid side energy storage price mechanism is established. Local governments should strengthen scientific planning and effective supervision of power grid side energy storage, and encourage power grid side to build energy storage facilities at key nodes according to the operation needs of the power system. Research on the establishment of power grid side independent energy storage power station capacity price mechanism, gradually promote the power station to participate in the power market; Explore how to include the cost and income of power grid alternative energy storage facilities into the recovery of power transmission and distribution price.

ECO STOR, a German energy storage developer, said recently that recent events and regulatory changes have completely reshaped the revenue mix of energy storage projects in Germany as the market shifts to grid-scale energy storage systems of more than 100MW. Georg Gallmetzer, managing director of ECO STOR, said German energy storage projects will get about half of their revenue this year from peak shaving, with the rest coming from grid support services and day trading. ECOSTOR's main business is the design and development of battery storage systems. Peak-modulated service is a service for which power is injected by a generation facility during peak demand loads of the distribution system operator (DSO) at an annual rate of eur 50 to EUR 100,000 /MW. But Gallmetzer said energy storage projects that come online after December 2022 May not get that revenue stream. "So from now on, the value of new projects will have to come from ancillary services and short-term deals, but fortunately the energy world has changed. The price of the auxiliary market has gone up and the spread on the short-term trade has multiplied, but at the same time the battery price has gone up by about 30 percent compared to last year." He added that ECO STOR's investment decisions on its current projects were made before the Conflict between Russia and Ukraine and the rise in commodity prices, but that the profit opportunities for these energy storage projects had increased significantly. It is remarkable that all this is happening because some of the pioneers in Europe's largest energy storage markets, such as the UK, such as Gore Street Capital and Anesco, have recently entered or made specific plans to enter the German energy storage market. When asked to comment on these initiatives, Gallmetzer cited land and grid access pressures in the UK market as key drivers of these companies' expansion abroad. "I think the land shortage in the UK has led to very high transaction prices for the rights to deploy energy storage projects, in the region of £100,000 /MW, which is actually a bit of a brake on the growth of the UK energy storage market," he said. Not all energy storage projects in the UK are trading at that price, though. Earlier today, Bluefield Solar announced the completion of a ￡56,000 /MW project rights deal. Part of the reason for these companies' increased interest in the German energy storage market may be the increased scale of new projects. So far, the market has been dominated by smaller energy storage projects, with battery storage systems operating with an average capacity of just 2.9MWh in 2021, according to a recent study published by the research firm. That is beginning to change. Power operator RWE, based in Essen, Germany, expects to have a 72MW energy storage project (one of two projects with a total scale of 117MW/128MWh) operational by the end of 2022. Fluence also announced that it is deploying a 100MW/200MWh battery storage project, but the exact delivery date is not yet known, while ECOS TOR expects to commission a 100W/200MWh battery storage system in 2024. Gallmetzer added, "This 100W/200MWh battery storage system will be the largest in Germany, but its time to hold this record may be short as many market participants have similar plans. And investors have been trying to make small investments and get more experience before scaling up, and these storage systems are starting to operate in the market and the experience with them is going to be very positive." ECO STOR is deploying a portfolio of energy storage projects that will be delivered by the end of this year with a total storage capacity of 100MWh. The company is comprised of Norwegian-based investors Agder Energi Ventures and Klaveness Marine Holdings, Delph25 and IGE (a holding company controlled by the founders of Covalis Capital) and ECO STOR is owned by the management.
