Battery Operation Manual
When the temperature of the NTC drops to the set value of recovery over-temperature, the BMS
recovers from over-temperature state, and the red ALM light extinguishes.
APL48150LFP is equipped with heater, sampling temperature is 0
℃
~ +10
℃
when charging,
sampling temperature is below 0
℃
when standing, heater power supply is 100W, heater starts.
Heater is optional for other models.
Battery capacity calculation function
Cell algorithm: About the use of soc and soh, soc uses the basic elements of the Ampere
integration and OCV method. The Ampere integration method and voltage, by the adjustment of
the algorithm, with higher precision data and Independent clock system, ensures reasonable
display during a single cycle. And the SOC estimation accuracy is
≤ ±
2%.
Balancing Function
When the battery pack is charged, if the cell voltage reaches the equalization turn-on voltage,
and the maximum voltage difference is greater than the equalization voltage difference, the cell
that meets the condition turns on the equalization function. Battery supports up to 7 channels
simultaneously to turn on equalization. The maximum equalization current is about 75mA.
Balance will stop when charging stops or the voltage difference of the cell is less than the setting
value.
Sleep and Wake Function
No.

Wake-up condition
Remark
1
In the idle state (no charge, discharge, no
communication), the lowest voltage of any cell is
lower than the set sleep voltage (can be set), after
30 minutes, enter normal sleep.

2
When the minimum cell voltage is lower than the
cell over-discharge protection value (can be set) or
the total voltage is lower than the overall over-
discharge protection value (can be set), and after 1
minute, the under-voltage sleep is entered.

Battery will enter to normal sleep after keeping
idle state (no charge and discharge, no
communication) for 24 hours.
