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

AE-48100 Lithium Battery Module User Manual
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：
Battery will stops charging when total voltage or any battery cell voltage reaches the rated
protection value during charging stage. When total voltage or all cell back to rated range, the
protection is over.
2.4.2 Current Protection
Over Current Protection in Charging：
when the charge current ＞75A, current limit protection mode is activated, current will be
limited to 10A.
Over Current Protection in Discharging：
When the discharge current is higher than the protection value, the battery buzzer alarms and
the system stops discharging. Protection is released after rated time delaying.
2.4.3 Temperature Protection
Low/Over temperature protection in charging：
When battery’s temperature is beyond range of 0℃~ +50℃during charging, temperature
protection is activated, device stops charging. The protection is over when temperature back to
rated working range.
Low/Over temperature protection in discharging：
When battery’s temperature is beyond range of -10℃~ +50℃during discharging, temperature
protection is activated, device stops supplying power to the outside. The protection is over when
temperature back to rated working range.
2.4.4 Other Protection
Short Circuit Protection：

AE-48100 Lithium Battery Module User Manual
If a short circuit occurs, the system starts short-circuit protection. It will recover after 60s if
unload. It won’t recover, if it still loaded.
Self-Shutdown：
When device connects no charge and discharge and no external communication for
over 48 hours, device will dormant standby automatically.
Caution
Battery’s maximum discharging current should be more than load’s maximum working current.
