T/GDCKCJH 026-2020 Polymer quasi-solid-state electrolyte power battery performance indicators and testing methods

Scope

Scope: This standard specifies the performance indicators and test-related terms and definitions of newly manufactured polymer quasi-solid electrolyte power batteries, as well as the requirements for performance indicators and test methods. This standard applies to the performance test of polymer quasi-solid electrolyte power batteries mounted on electric vehicles. Other types of solid electrolyte power batteries can refer to this standard for implementation. Main technical content: This standard specifies the electrical performance requirements of polymer quasi-solid electrolyte power battery cells and modules, and provides detailed specifications for the testing of electrical performance parameters of polymer quasi-solid electrolyte power battery cells and modules, including room-temperature discharge capacity, AC internal resistance, high- and low-temperature discharge capacity, standard cycle life, etc. It also standardizes the performance test procedures of power batteries and the number of power batteries required for the test.
