Safety  Characteristic of car 18650 battery

NO. Item Standard Test Method
1 Overcharge No fire、No explosion After standard charge, rest for 10mins; then charge at constant current of 3C to 10V.(or charge at 3C for90mins).
2 Forced discharge No fire、No explosion The battery to be discharged with standard discharging condition, Inverse charge current =1C;time: ≥90mins

               3 Short Circuit test No fireNo explosion The battery to be fully charged with standard charging condition, and short the positive and negative terminals with wire resistance ≤50mΩ.Tests are to be conducted at 23℃±3℃  and at 55℃ ±5℃, keep 24h or casetemperature decline to 20% of the max temperature ,test is over.
4 Crush test No fire/No explosion A battery is crushed between two flat surfaces. The applied force is 13 kN±1kN by hydrocylinder, Once the maximum pressure has been obtained or voltage decrease to 1/3 of nominal voltage sharply, then release pressure.
5 Shock test No fire/No explosion The full charged battery is fixed on shock table, to force a certain shock to three mutual vertical direction, in initial3ms, the min. average acceleration is 75gn,the peak acceleration is between 125gn and 175gn.
6 Heating test(130°C) No fire/No explosion The cells are fully charged with standard charging condition, and put into incubator with nature air or cycled air convected, heat battery by velocity of 5°C ±2°C/min to130°C±2°C,and maintain for 10mins.
7 TemperatureCycling Test no leakage, no fire, no explosion The fully charged batteries are placed in a test chamber and subjected to the following cycles: a) Raising the temperature to 75°C ±2°C within 30 minutes and maintaining this temperature for 6 hours.
