    2. Battery Pack Reliability Test


    2.1 Testing condition (Unless Special Requirements)

    Temperature:20±5℃ Relative Humidity: 45~75%

    Atmosphere Pressure: 86~106kPa

    All testing under full capacity


    2.2 Reliability Test

    No.ItemsStandardsTesting Methods
    1Vibration TestingThe appearance of battery should not leakage, break or explosionFix a charged battery on a vibrating table, vibrate it for 90 minutes in three mutually perpendicular directions at the 0.8mm resonance. The frequency is to be varied at the rate of 1hz/min between 10 and 55 hertz.
    2High Temperature Discharge TestingThe battery should be no remarkable breakage, distortion. Discharge time should not less than 255minsPlace a full charged battery under the environments of 55℃ for 2 hours. Discharge it at the current of 0.2C to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.
    3Low Temperature Discharge TestingThe battery should be no remarkable breakage, distortion. Discharge time should not less than 180 minutePlace a full charged battery under the environments of -20℃ for 15-24 hours. Discharge it at the current of 0.2C to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.
    4Constant Humidity & Temperature TestingThe battery should be no remarkable breakage, distortion. Discharge time should not less than180minsPlace a full charged battery under the environments of 40℃ and 90% - 95%RH for 48 hours. And keep it in the room temperature for 2 hours. Then discharge it at the current of 0.2C to the cut-off voltage.
    5High & Low Temperature StorageThe battery should be no remarkable breakage, distortion. And charge/discharge normallyPlace a full charged battery in a oven with 55±2℃ for 2 hours, then keep it under 20±5℃ for 4hrs, then place it in a oven with -20±2℃ for 2 hours, then keep for 4 hours under 20±5℃, cycle as high temperature-normal temperature-low temperature-normal temperature-high temperature for 10 times

    3. BATTERY PACK SAFETY TEST


    3.1 Testing condition (Unless Special Requirements)

    Temperature:20±5℃ Relative Humidity: 45~75%

    Atmosphere Pressure: 86~106kPa

    All testing under full capacity


    3.2 Battery Pack Safety Test

    No.ItemsStandardsTesting Methods
    1Short-CircuitThe battery should be no remarkable breakage, distortion. And charge normally.Use a resistor with less than 0.05Ω to make the battery short circuit for 1 hour. The appearance and characteristics are normal.
    2Over Discharge Protection TestThe battery should be no remarkable breakage, distortion. Appearance and charge are normal.Discharge the battery at the rate of 0.2C with the load of 30Ω for 24h . Charging for 10sec with specified adapter , and check the voltage(8V)
    3Impact TestThe battery should be no explosion or catch firePlace a full charged battery on a flat and put a stainless steel stick (Diamond 7.9mm) in the middle of the battery upright . Beat the steel stick with 9.1Kg
