1.The main changes in the new version of Chapter 38.3 are as follows:
(1) Add sodium ion battery testing clauses;
(2) Modified the testing requirements for integrated battery packs:
For integrated battery packs that are not equipped with overcharge protection, if they are designed only for use as components of other batteries, devices, or vehicles that provide overcharge protection:
-Need to verify overcharge protection in other batteries, devices, or vehicles;
-Charging systems without overcharging protection must be prevented from being used through a physical system or program control.
2.Comparison of testing differences between sodium ion batteries and lithium-ion batteries:
(1) Sodium ion batteries do not require a T.8 forced discharge test;
(2) For sodium ion cells or sodium ion single cell batteries, the cells are fully charged during the T.6 compression/impact test.
3.Sodium battery UN38.3 test standard sample delivery requirements:
●Single cell: 20
●Single cell battery: 18 batteries, 10 cells
●Small battery pack (≤ 12Kg): 16 batteries, 10 cells
●Large battery pack (>12Kg): 8 batteries, 10 cells
