Testing method |
1 |
Discharge performance in normal temperature |
Discharge capacity /standard capacity×100% 0.5CA ≥100% |
Charge with 0.5CA standard charge in the condition of temperature 25ºC±5ºC,relative humidity 45%~80% (if there is no especial statement,the charging way is same as this), rest for 10min,separated discharge with 0.5CAto cut-off voltage40V,cycles for three times,One cycle capacity arrive standard, that's to say it is qualified.(The below as the same); |
2 |
Charging keep ability in normal temperature |
Rest capacity≥standard capacity *90%
|
After standard charging,store at 25ºC±5ºC for a month, and then discharge to cut-off voltage 40V by 0.5CA. Then measure the capacity of cell. |
3 |
Charge protection strategy test |
Charging protection when maximum single cell voltage > 3.65V
|
Charging protection when maximum single cell to voltage 3.65V, |
4 |
discharge protection strategy test |
Discharge protection minimum single cell<2.5V |
After the 0.5CA standard charge full of electricity, then 0.5CA discharge to the termination voltage 40V, , test the minimum single cell voltage |
5 |
Cycle life |
Capacity≥ Standard capacity *80% |
After 0.5 CA standard charged ,discharge with 0.5 CA to 40V.rest for10min,cycles for 2400 times. |
6 |
Storage performance |
Capacity can be kept ≥80% Storage for 12months. |
After standard charged,let it rest for 12 months as a open circuit, discharging it until40 V by 0.5CA, and then measure the leftover capacity. Measure its recovery capacity by 0.5 CA /0.5CA . Undertake 3 cycles, it passes when one cycle meets the standard. |
