##In 2023, the preparation of four group standards in the field of energy storage will be fully launched ###All relevant units: In March 2022, the National Development and Reform Commission and the National Energy Administration jointly issued the "Guiding Opinions on Accelerating the Development of New Energy Storage", the "Implementation Plan for the Development of New Energy Storage in the 14th Five-Year Plan" and the "14th Five-Year Plan" Energy Field Science and Technology Innovation Plan and other documents. The document proposes to promote the diversified development of energy storage technology routes. As a strategic emerging industry with technological innovation advantages, energy storage is an important technology and basic equipment for building new power systems, and an important support for achieving the goal of carbon peak and carbon neutrality. By 2025, the installed capacity of new energy storage will reach more than 50 million kilowatts, and the cumulative installed capacity will reach about 40GW; after 2025, the annual installed capacity increase of electrochemical energy storage will remain at 12-15GW; it is expected that by 2030, the installed capacity of electrochemical energy storage is expected to reach 110GW.

With the support of various national policies, the electrochemical energy storage industry will usher in major development opportunities. The Energy Storage Application Branch of China Chemical and Physical Power Supply Industry Association plans to launch the "OPzV Solid Lead Battery for Energy Storage Power Stations", the "Safety Test Standard for Lithium Ion Batteries for Energy Storage", and the "Electrochemical Energy Storage Power Stations Energy Management System Technical Specifications" and "Energy Storage Battery Liquid Cooling Radiators". The preparation of four group standards in the field of energy storage. Industry representative battery manufacturing companies, upstream and downstream suppliers, scientific research institutions, universities, etc. are invited to participate. The specific project situation is as follows: ###1."OPzV solid lead battery for energy storage power stations" At present, lithium battery safety accidents occur frequently at home and abroad, the production safety situation is severe and complex, and the alarm for safety management and control of energy storage power stations is sounding again. In the face of painful lessons, we need to be market-oriented and develop "high-safety, low-cost, and sustainable" electrochemical energy storage technology to solve the safety issues, cost issues and sustainable resource development issues that the industry has exposed. OPzV solid-state lead batteries are developed products based on renewable energy storage technology of "long-term design, low-carbon manufacturing, safe operation and maintenance, and green recycling". They have advantages such as high safety, long life, and recyclability to realize the system. The reduction of life cycle costs has helped achieve the dual carbon goal through market verification of energy storage batteries that adapt to new power systems. At present, OPzV solid-state lead batteries are a new technical route and development product in the new energy storage market. There is no same standard in the industry. In order to standardize competition in the energy storage battery market, strengthen quality management of energy storage systems, and realize the application of OPzV solid-state lead batteries in energy storage battery systems. There are standards to follow in terms of design, selection and verification, and relevant standards are urgently needed to standardize them to provide a basis for the research and development, production and application of OPzV solid-state lead batteries. ###2. Safety Test Standard for Lithium Ion Batteries for Energy Storage Under the guidance of the "double carbon" goal, the energy structure has been accelerated to clean. Due to the intermittent and volatile problems of new energy power generation methods such as wind power and photovoltaic power generation, and the volatile characteristics of the power consumption side, how to ensure and balance the stability of both sides of power supply and demand has become a problem that must be overcome now and in the future. Developing efficient and safe energy storage technology is a key solution to the above problems.

The energy storage system stores unstable electricity such as wind power or photovoltaics during low troughs by "cutting peaks and filling valleys", and transforms and stabilizes power output at peak peaks. Among many energy storage technology routes, with the advancement of battery technology and the reduction of costs, lithium-ion batteries are considered to be one of the most potential power energy storage carriers. As of 2021, my country's new energy storage installed capacity, mainly electrochemical energy storage, has accumulated about 5.7 GWh. In 2025, the installed capacity of new energy storage will reach more than 30GWh, which means that the installed capacity of new energy storage will be at least 5-6 times. Growth space.

Currently, electrochemical energy storage is still in the development stage, and safety is the lifeline of energy storage development. Only when safety is better guaranteed can the energy storage industry develop better. Lithium-ion batteries contain materials such as positive and negative electrodes with high energy density, flammable separators and electrolytes. Under unreasonable use and extreme circumstances, they can easily cause thermal runaway of the battery, accompanied by smoke, fire and explosion. Therefore, it is necessary to improve the safety testing standards for lithium-ion batteries for energy storage as soon as possible to evaluate the safety and possible problems of the batteries to ensure the safe operation of energy storage power stations. ###3. Technical Specifications for Energy Management Systems of Electrochemical Energy Storage Power Stations The electrochemical energy storage power station energy management system (EMS) is the intelligent management part of the energy storage system, which mainly realizes the safe and optimized scheduling of battery energy. It has complete energy storage power station monitoring and management functions, covering detailed information such as power grid access, PCS, BMS, in-station booster station, in-station fire protection, etc., realizing data collection, data processing, data storage, data query and analysis, visual monitoring, and multi-function coordination, AGC/AVC, primary frequency modulation, dynamic voltage regulation, alarm management, statistical reporting and other functions. Energy storage EMS can conduct real-time monitoring and historical technical analysis of battery performance. Based on the analysis results, an intelligent distribution strategy is used to control the charge and discharge of the battery pack, which optimizes battery performance and improves battery life, with significant economic benefits.

At present, there is no same specification in the industry for electrochemical energy storage power station energy management systems. In order to standardize the market competition for electrochemical energy storage power station energy management systems, strengthen the quality management of energy storage systems, and realize that electrochemical energy storage power station energy management systems can be used in energy storage systems. There are standards to follow in terms of design, selection, and verification, which are urgently needed to be standardized by relevant standards to provide a basis for the research and development, production and application of electrochemical energy storage power station energy management systems. ###4."Energy storage battery liquid cooling radiator" 18519109706
