Status indication
4.3 Functional description
●
Standby state: After the BMS is correctly connected and powered on, and there is no
protection state of over-voltage, under-voltage, over-current, short circuit, over-temperature,
under-temperature, etc., press the reset button to turn on the device, and the BMS is in standby
state.
In the BMS standby state, the running light flashes, and the battery can be charged and
discharged.
●
Cell overcharge protection and recovery: When any section of the battery cell is higher
than the set value of cell overcharge protection, the BMS enters the overcharge protection state,
and the charging device cannot charge the battery.
After cell over-voltage protection, when the highest cell voltage drops below the cell
overcharge recovery value and the SOC is lower than 96%, the overcharge protection state is
released. It can also be discharged.
●
Total voltage overcharge protection and recovery: When the battery voltage is higher
than the total voltage overcharge protection setting value, the BMS enters the overcharge
protection state, and the charging device cannot charge the battery. When the total voltage drops
below the total overcharge recovery value and the SOC is lower than 96%, the overcharge
protection state is released. It can also be discharged.
●
Single over-discharge protection and recovery: When any section of the battery cell is
lower than the set value of the single over-discharge protection, the BMS enters the
over-discharge protection state, and the load cannot discharge the battery. BMS shuts down after
1 minute of communication.
After over-discharge protection occurs, charging the battery pack can release the
over-discharge protection state. Or press the reset button once, and the BMS will turn on and
re-check whether the battery pack voltage reaches the restored value.
●
Total voltage over-discharge protection and recovery: When the battery voltage is lower
than the total voltage over-discharge protection setting value, the BMS enters the over-discharge
protection state, and the load cannot discharge the battery. BMS shuts down after 1 minute of
communication.
