All tests, except as specified, were performed under the following conditions (standard test conditions):
Ambient temperature: 25 ± 5℃ (if the ambient temperature is below 20℃, the battery pack should be set for more
than 5 hours at 20℃ before testing)
Environmental humidity: 30%~80%
Atmospheric pressure: 86kpa~106kpa
Set of standard charge and discharge
Standard charging: Charge the battery pack at 20A current constant current constant voltage to the cut-off voltage
292V, cut-off current 0.02C(0.4A);
Electrical performance, safety performance, mechanical performance test
| Test item | Test method | Technical requirement |
Discharge capacity | Under the standard test condition,the pack is charged to the standard,and discharged at 0.1C,and recorded the capacity. | ≥100% ≥100% standard capacity |
| ischarge capacity at -20℃ | After standard charging of the battery pack,storage for 8H at -20±2℃, discharge at 0.1C to the end voltage,and record the discharge capacity. | ≥65% standard capacity（Without BMS ） |
| Discharge capacity at 55℃ | After standard charging of the battery pack,storage for 8H at 55±2℃, discharge at 0.1C to the end voltage,and record the discharge capacity. | ≥97% standard capacity |
| Charge retention(residual capacity)and capacity recovery | After standard charging and discharging of the battery pack,record the initial capacity,then storage for 28 days at 15~35℃,then discharge and record the residual capacity;then record recovery capacity after standard charge and discharge. | Residual capacity(charge retention rate)≥95%; Recovery capacity≥97% |

| Storage at 55℃ for 7 days | After standard charging and discharging of the battery pack,record the initial capacity;after standard charging of the battery pack,storage for 7days at 55±2℃,then discharge and record the residual capacity;then record recovery capacity after standard | Residual capacity≥92% Recovery capacity ≥95% |
Safety performance
| Test item | Test method | Technical requirement |
| Short circuit | After standard charge and discharge the battery pack,placed it in the explosion-proof box,then short-circuit to the positive and negative electrodes outside the battery with internal resistance less than 100100mΩ,record the surface temperature of the battery during the test,short circuit duration 10min,that is the completion of the test.Or short circuit safety evaluation test with single cell. | No fire,no explosion. (Test without protect circuit and shell) |
| Over-charge | After standard charge of the battery pack,and continuously discharge it at 0.5C with a load meter,then complete the test until the voltage of a single cell to 0~0.5V. | No fire,no explosion. (Test without protect circuit and shell) |
