What test does the energy storage battery face?

Energy storage battery standards face many challenges. Although there is still no strict distinction between energy storage batteries and power lithium-ion batteries, with the improvement of energy storage battery standards, there will eventually be a difference between the two. In fact, it has become a consensus in the industry that energy storage batteries should have their own independent standards and systems. The difference in the application scenarios of the two determines the differences in their battery performance requirements. Power lithium-ion batteries are more concerned about high energy density and high rate, while energy storage batteries are more concerned about long life, low cost, and high safety. Fully use power lithium-ion batteries as energy storage batteries, not only the performance is difficult to meet the standard, but also there are potential safety hazards. The director of the Energy Storage Battery Testing and Evaluation Technology Research Office of my country Electric Power Research Institute Co., Ltd., said in an interview with a reporter from my country Electric Power News. With the vigorous development of my country's energy storage industry, the performance evaluation standards and systems dedicated to energy storage batteries urgently need to be gradually improved. Last year, my country has successively announced more than a dozen national standards for the energy storage industry, covering energy storage equipment such as energy storage batteries, energy storage converters, and grid connection of energy storage systems. The national standards at the equipment level are basically complete. The most important thing that is lacking is the standards for system safety protection, fire protection, dispatch and operation control, and life cycle management evaluation. Some of the problems are world-wide technical problems, and several years of technology are still needed. Accumulation can be perfected. Guan Yibiao said frankly that from the performance testing and evaluation practice of energy storage batteries carried out by the Chinese Academy of Electric Power Research, if the performance parameters of energy storage batteries are marked according to the application standards of power lithium-ion batteries, it may be connected to the most basic energy storage batteries. National standards are not enough. Therefore, there is a very contradictory point in energy storage projects. If the evaluation is strictly in accordance with the national standards for energy storage batteries, the performance parameters marked by power lithium-ion batteries will be greatly reduced in energy storage applications, which means that power lithium-ion batteries are Operating parameters should be lowered to meet the requirements, and this will result in an increase in the cost of energy storage batteries. Who should pay for the additional costs is still a matter of dispute. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
