Different from the passive balance board, the active balance circuit uses energy transfer to balance the battery voltage, which significantly improves the overall efficiency of the battery pack!
2. Balance principle:
When the voltage difference between adjacent batteries reaches more than 0.1V, the chip triggers equalization work internally, until the voltage difference between adjacent batteries stops working within 0.03V.
3. Wiring definition (4S as an example):
0, the total negative pole of the battery pack (the negative pole of the first battery)
1. The positive pole of the first battery
2. The anode of the second battery
3. The positive pole of the third battery
4. The positive electrode of the fourth battery
If 3 strings of battery packs are not connected to terminal 4, if 2 strings of battery packs are not connected to terminals 3 and 4
This product contains equalizing circuit and line set
Performance parameters:
Working voltage 2.0V-4.5V (3.7V ternary, 3.2V lithium iron battery common) (not applicable to lithium titanate batteries)
Balance current:
The adjacent voltage difference is above 0.1V (current is about 0.5-6A);
The adjacent voltage difference is more than 0.2V (reach the maximum equalization current 6A);
The smaller the pressure difference, the smaller the equalizing current.
