Communication equipment lithium battery protection function what?

Lithium battery protection and alarm function of communication equipment:

1. Over-charge protection. When the battery string is in the overcharged state, disconnect the charging circuit and generate an alarm. Ensure that the battery string does not leak, smoke, fire, or explode.

2. Short circuit protection. If a short circuit occurs at the output end of the battery string, cut off the circuit immediately and generate an alarm. The battery string should not leak, smoke, fire, or explode. After troubleshooting, it should be able to resume work manually or automatically. After instantaneous charging, the battery pack voltage should be no less than the nominal voltage.

3. Reverse connection protection. If the battery pack is required to test, the circuit should be cut off and the alarm should be generated. The battery pack should not leak, smoke, fire or explosion. After troubleshooting, should be able to automatically resume work; After instantaneous charging, the battery pack voltage should be no less than the nominal voltage.

4. Overload protection. When the battery string discharge current reaches the overload protection current value, cut off the circuit and generate an alarm. The battery string should not leak, smoke, fire, or explode. After troubleshooting, should be able to automatically resume work; After instantaneous charging, the battery pack voltage should be no less than the nominal voltage.

5. Temperature protection. When the temperature reaches the protection point range listed in Table 2, the battery string should cut off the circuit and generate an alarm. Except for the high temperature protection of BMS components in the battery string, the battery string will automatically resume working when the temperature reaches the recovery point range listed in Table 2. The battery pack should not leak, smoke, fire, or explode.
