Safety Performance Requirements
| Item | Test Method | Require |
|---|---|---|
| Short Circuit | After being fully charged using the standard charging method at 25 °C, short-circuit the positive and negative terminals of the battery pack’s discharge port with wires (wire resistance 80 ± 20 mΩ) for 1 hour. | The battery pack should not leak, ignite, or explode. |
| OverCharge | After charging with the standard charging method at 25 °C, set the constant current source to 1.25 times the nominal voltage and 0.11 (A). | |
| Discharge | Discharge the battery pack to the termination voltage or battery pack protection, and then continue discharging for 5 hours at 0.11 (A). | |
| Constant Damp Heat Test | After charging using the standard charging method at 25 °C, place it in a constant temperature and humidity chamber at (40 ± 2) °C and relative humidity of 90-95% for 48 hours; After 7 hours of storage, visually inspect. | Visually inspect the appearance and ensure that there is no leakage, smoke, fire, or explosion. |
| High and low temperature impact | After charging using the standard charging method at 25 °C, place the battery pack in an environment with a temperature of 75 °C ± 2 °C for 6 hours, then move it to an environment with a temperature of -40 °C for 6 hours. The time interval between moving from the highest temperature to the lowest temperature should not exceed 3 minutes. Repeat the above steps, after 10 cycles, remove and let it sit for 24 hours, and visually inspect. |
