锂电池(电芯)做圆形PSE认证,日本本土标准是 Attached -Table 9 Lithium ion secondary batteries,总的测试项目有:
Continuous charging at c***tant voltage
Vibration
Battery enclosure test at high ambient temperature
Temperature cycling
External short circuit
Free fall
Mechanical shock (crash hazard)
Thermal abuse
Crushing of cells
Low pressure
Overcharge (the test cell with protective device)
Forced discharge
Cell protection against a high charging rate
Forced internal short circuit of cells
Function of the overcharge protection of batteries
Free fall of appliance
电池组和电芯的测试项目略有差异,具体工程师来评估。另外有一个持续充电测试Continuous charging at c***tant voltage要28天才能做完,预计认证完成时间是28-30天。
样品需求:20个以上
电池组(battery),是有保护电路板,并且有一个或者多个电芯组成的电池产品,常见的电池组如移动电源。
电芯(Cell): 电芯只有一个(片),内部无保护电路,常见的电芯,如从移动电池里面拆下来的片状电芯。
