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

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 recoveryAfter   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%
Cycle lifeDischarge  the  battery  pack  at  0.5C  after  standard charge,terminate   the   cycle   life   test   when   the discharge capacity is less than 80% of initial capacity.≥3000n times
Storage at 55℃ for 7 daysAfter   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 itemTest methodTechnical requirement
Short circuitAfter 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-chargeAfter 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)
