2.4 Battery Management System(BMS)
2.4.1 Voltage Protection
Low Voltage Protection in Discharging：
When any battery cell voltage or total voltage is lower than the rated protection value during
discharging, the over-discharging protection is activated, and the battery buzzer makes an alarm
sound. Then battery system stops supplying power to the outside. When the voltage of each cell
back to rated return range, the protection is over.
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 total
voltage or all cell back to rated range, the protection is over.

PowerDepot H5B series User Manual

2.4.2 Current Protection
Over Current Protection in Charging：
When the charge current of each module ＞90A, current limit protection mode is activated,
current will be limited to 1A，protection is removed after rated time delaying 10S. Circulate like
this until the current is lower than 90A.
Over Current Protection in Discharging：
When the discharge current is higher than 100A, the battery buzzer alarms and the system stops
discharging after 15s. After protection, the discharging will restore in 60s delay or immediately
when there is charging current.
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 0 ℃~+55 ℃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 -20℃~+55℃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.
