    General Check

    ItemTest methodStandard
    AppearanceVisually inspect the appearanceThe appearance of the product should be clean and should not have cracks or cracks.
    lines, dents, trachoma, deformation and other forms of
    Mechanical damage, there should be no rust on the output end.
    polarity markUse a multimeter to test the positive and negative terminals of the battery packThe polarity should be consistent with the mark
    Tag & ModelVisually inspectShould be correct
    open circuit voltageUse a multimeter to test the open circuit voltage为51.2V~53V
    Discharge capacity at room temperatureCharge the battery pack according to constant current and constant voltage. After leaving it aside for 1 hour, place the battery pack in a standard environment and discharge it at a constant current of (0.2C) to the end-of-discharge voltage or battery pack protection.Discharge capacity ≥ minimum nominal capacity

    Environmental adaptability

    ItemTest methodStandard
    Low temperature capacityCharge the battery pack according to according to constant current and constant voltage, and then place the battery pack in a low temperature box at -10℃±2℃ for 8 hours, and then
    (0.1C) Current discharge to end voltage or until trigger battery pack protection.
    Battery pack capacity ≥70% rated capacity
    High temperature capacityCharge the battery pack according to according to constant current and constant voltage, and then place the battery pack in high temperature box at 55℃±2℃ for 8 hours, and then
    (0.1C) Current discharge to end voltage or until trigger battery pack protection.
    Battery pack capacity ≥99% rated capacity
    Charge retention ability and charge recovery abilityCharge the battery pack according to according to constant current and constant voltage and place the pack in a standard environment for 28 days;Then discharge battery pack to the end voltage with (0.2C) current or battery pack protection is triggered. Then fully charge the pack, then leave it for 1 hour, discharge it with (0.2C) current to the end voltage or trigger battery pack protection.After 28 days, the discharge capacity of the battery pack is ≥96% of the rated capacity;
    Life cycleAfter the battery pack is fully charged, leave it aside for at least 10 minutes. The battery pack is discharged with (0.2C) current until it reaches the end voltage or triggers battery pack protection. A charge-discharge cycle is completed.
    ring. Repeat the charge and discharge cycle.
    The 1000th discharge capacity of the battery pack is ≥80% rated capacity
    Cycle in high temperatureAfter the battery pack is fully charged in an environment of 55°C, it is left aside for at least 30 minutes. The battery pack is discharged with a current of 1C until it is discharged to the end voltage or battery pack protection, which completes one charge and discharge cycle. Repeat the charge and discharge cycle.The normal temperature discharge capacity of the battery pack after the 100th high-temperature cycle is ≥95% of the pre-cycle capacity
    Cycle in low temperatureAfter the battery pack is fully charged in an environment of -40°C, it is left aside for at least 30 minutes. The battery pack is discharged with a current of 1C until it reaches the end voltage or battery pack protection, which completes one charge and discharge cycle. Repeat the charge and discharge cycle.The normal temperature discharge capacity of the battery pack after the 100th low-temperature cycle is ≥95% of the pre-cycle capacity

    Safety performance

    ItemTest methodStandard
    Short circuitAfter standard charging of the battery pack, place it in an explosion-proof box and use a wire with an internal resistance of less than 100mΩ to short-circuit the positive and negative terminals outside the battery pack.Record the battery surface temperature during the test, and the short-circuit duration is 10 minutes, that is, the test is completed or assess the safety performance of some single battery cells.No fire, no explosion
    Over chargeAfter standard charging of the battery pack, use a constant current and constant voltage source to charge a single cell of the battery pack (0.2C). After constant current charging reaches 5V, switch to constant voltage charging until the cut-off current reaches 0A or the surface temperature is low.
    The test ends when the ambient temperature is below +10°C.
    No fire, no explosion
    Over dischargeAfter charging the battery pack to the standard, use a load meter to continuously discharge the battery pack at 0.5C until the voltage of a single cell reaches 0~0.5V, then end the test.No fire, no explosion
    VibrationFix the fully charged battery pack on the vibration table and vibrate cyclically from 10Hz to 55Hz for 90min to 100min with a frequency sweep rate of 1oct/min and a displacement amplitude of 0.76mm (single amplitude).No fire, no leakage, no explosion, The battery pack works fine.
