Certification Introduction:

GB/T 36276-2023 "Ion Batteries for Electric Power Storage" will be released at the end of December 2023 and will be
Implemented on July 1, 2024. With the rapid development of the battery energy storage market in recent years, accidents have also occurred one after another.
Based on this, compared with the old version of the standard in 2018, the overall structure of the new version of the standard remains basically unchanged, but the technical conditions
The software is more stringent and the testing requirements are more complete.

The structural hierarchy 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 are the cornerstones of the operation of energy storage power stations.
GB/T 36276-2023 covers key operating parameters and performance safety from battery cells, battery modules to battery cluster levels, and puts forward clear requirements for all levels of batteries.
Overall, the new version of GB/T 36276 has many changes, such as:
♦ Performance part: All performance index requirements have been tightened;
♦ Cycle part: In order to shorten the cycle time, it was changed to 45C cycle;
♦ Thermal runaway part: changed to dual trigger of overcurrent and heating;
♦ Safety part: The test conditions are also tightened, and the short circuit and extrusion conditions are more stringent;
Strict testing requirements pose great challenges to manufacturers. Manufacturers also need to keep abreast of the new version of the standard requirements and make targeted design changes to their products to ensure that they successfully pass the test.
