With the rapid development of the battery energy storage market in recent years, accidents are also emerging. Based on this, the overall structure of the new standard is basically unchanged compared with the old standard in 2018, but the technical conditions are more stringent and the testing requirements are more perfect.
the structure level of the energy storage system is as follows: battery cells are connected in series and parallel to form battery modules, battery modules are connected in series and parallel to form battery clusters, battery clusters are connected in parallel to form a battery energy storage system, and battery energy storage systems are connected in parallel to form a battery energy storage power station. The performance and safety of the battery system is the cornerstone of the operation of the energy storage power station.
GB/T 36276-2023 covers the key operating parameters and performance safety from the battery cell, battery module to the battery cluster level, and puts forward clear requirements for all levels of the battery.
Due to the long overall length, the comparison details of the key changes of the new and old standards only for battery cells are as follows:
