2.4.1 Voltage Protection
Low Voltage Protection in Charging When any module cell 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 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.
2.4.2 Current Protection
Over Current Protection in Charging
When the charge current of each module45A, current limit protection mode is activated, current will be limited to 4Aprotection is removed after rated time delaying 10S. Circulate like this until the current is lower than 45A.
Over Current Protection in Discharging
9

Powerbox F series User Manual
When the discharge current is higher than the protection value, the battery buzzer alarms and the system stops discharging. The system is released from protection after the rated delay time of 1min.
Caution:
The buzzer sound alarm setting can be manually turned off on the background software, 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 -5 ~+55 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 -20~+55 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 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 connects no external loads for over 72hours, device will dormant standby automatically.
Caution
The maximum operating current required for the electrical load shall be less than the maximum discharge current capacity of the battery.
