5.6 Electrical Performance 电性能测试
5.6.1 Temperature Dependence of Capacity (Discharge) 不同温度放电容量
Cells shall meet the discharge capacity requirements listed in the below table under respective discharge
temperatures. The capacities are to be measured with constant discharge current 0.5CmA (2.75V cut-off)
after standard charge at 25±2℃.
电池芯在 25±2℃标准充电后,然后在 30 分钟内冷却或加热到测试温度,并在此温度下保持 1 小时,再以
0.5CmA 进行放电测试.
