2.4.1 Voltage Protection
Low Voltage Protection in Discharging：
When any module cell voltage is lower than the rated protection value during discharging, the over-
discharging protection be activated, and the battery buzzer makes alarm sound. Then battery
system stops supplying power to the outside. When the voltage of each cell recovers to rated value
and total voltage restored to above 45V, the protection is released.
Over Voltage Protection in Charging：
During charging stage, the system will stop charging when the total voltage of the battery pack is
higher than rated value or the voltage of any single cell reaches the protection value. When the
total voltage returns to below 52V and the cell voltage back to below the rated protection value,
the protection is released.

PowerDepot H5 series User Manual

2.4.2 Current Protection
Over Current Protection in Charging：
When the charge current of each module＞45A, current limit protection mode is activated, current
will be limited to 5A，protection is removed after rated time delaying 10S. Circulate like this until
the current is lower than 45A.
Over Current Protection in Discharging：
When the discharge current is higher than the protection value 55A, the battery buzzer alarms and
the system stops discharging. The system is released from protection after the rated delay time of
1min.
Note:
The buzzer sound alarm setting can be turned off on the background software manually, and the
factory default is on.
2.4.3 Temperature Protection
Low/Over temperature protection in charging：
When battery’s temperature is beyond range of -5oC~+55oC during charging, temperature
protection be activated, device stops charging. The protection is released when it back to rated
range of working temperature.
Low/Over temperature protection in discharging：
When battery’s temperature is beyond range of -20oC ~+55oC during discharging, temperature
protection be activated, device stops supplying power to the outside. The protection is released
when it back to rated range of working temperature.
2.4.4 Other Protection
Short Circuit Protection：
When the battery is activated from the off state, if a short circuit occurs, the DC circuit breaker will
respond first. If the DC circuit breaker does not operate, the short circuit protection function of
BMS will be activated automatically and cut off the device’s output.
Self Shutdown：
When device have no connection of external loads, power supply and communication equipment
for over 72 hours, the device will go into hibernation automatically.
Caution
The maximum operating current required for the electrical load shall be less than the maximum
discharge current capacity of the battery.
