Energy storage battery standardization

Standardization efforts in emerging battery tech have been considered. Rational suggestions have been proposed for battery safety standardization efforts. In recent years, electric vehicle safety incidents related to batteries have occurred frequently enough to question the adequacy of the current international safety standards.

Based on the above analysis, the establishment of battery standards should fully consider the following aspects. First, from the perspective of the whole life cycle of the battery, the safety and reliability of the whole process—from manufacturing to application and decommissioning—needs to be guaranteed.

However, some of these standards are designed for fuel vehicles, so it is difficult for testers to find accurate matching test methods for some tests, so it is recommended to accelerate the development of corresponding standards for electric vehicles and update the standards system architecture for battery management system testing.

Although domestic standards for relevant equipment in the battery manufacturing process exist, such as DB13/T 1513–2012 and GB/T 38331–2019, the process of battery manufacturing is quite complicated and cumbersome, and the set of standards on the manufacturing process are not complete and need to be further developed.

Diagnostics and determination of the State of Health (SoH) for batteries with a management system – Part 3: advanced design Safety of Li-ion batteries from electrically propelled road vehicles for use in stationary applications Homologised batteries in road vehicle application have to comply with legal requirements in stationary use.

China's existing battery safety standards mainly focus on post-production battery testing, namely the mechanical abuse, electrical abuse, thermal abuse, and environmental abuse testing described above, and then there are standards for battery production equipment as well as the production process and recycling of retired batteries.
