This test is allowed to be repeated for 3 times if the discharge capacity fails to meet the technical requirements.2Dischargeability at different temperatureDischarge capacity / Nominal capacity×100% A) 55ºC ≥95%B) -20ºC ≥70%After standard charged, the cell undergo a rest for 5h at (55±2 )ºC, then is diacharged by current 1.0C(A) to cut-off voltage 2.5V;After standard charged, the cell undergo a rest for 24h at (-20±2)ºC, then is diacharged by current 1.0C(A) to cut-offvoltage 2.0V.3Charge retention and recovery at 25ºCresidual capacity ≥ nominal capacity×95% Recovered capacity≥nominal capacity×97%After standard charged,the cell undergo a rest for 28 days, then is diacharged by current 1.0C(A) to cut-off voltage 2.5V. The discharge capacity is called residual capacity. After standard charged again,the cell undergo 30min's rest , then is diacharged by current 1.0C(A) to cut-off voltage 2.5V. The discharge capacity is called recovered capacity.4Cycle life at 25ºC≥3500 cycle @1C/1CAt (25±2)ºC, 300kgf clamp force: the cell is charged by current 1.0C (A) to 3.65V, then kept at this voltage until the current is less than 0.05 C(A), followed by 30min rest, subsequently the cell is diacharged by current 1.0C (A) to 2.5V . Cycle continues until the capacity decays to 80% of the nominal capacity6End-of-life managementDischarge capacity / Nominal capacity <70%The cell shall be stopped using when the life limit is exceeded.Safety PerformanceNo.ItemRequirementsMeasuring Procedure1OverdischargeNo fire,explosion,electrolyte leakageReference: GB/T 31485-2015 safety requirements and test methods for power batteries for electricvehicles2OverchargeNo fire,explosion3ShortcircuitNo fire,explosion4DroppingNo fire,explosion,electrolyte leakage5HeatingNo fire,explosion6CrushingNo fire,explosion7PriskingNo fire,explosion8Seawater immersionNo fire,explosion9Temperature cycleNo fire,explosion,electrolyte leakage10Low pressureNo fire,explosion,electrolyte leakage
