42V 4A charger for 36V 10 cells Li-ion battery pack
a. The charger integrates power factor correction (PFC), it can avoid the impact of high current and can't produce pollution on the grid.
b. Efficiency>94% ,Power Factor>0.98 for charger @120V input, or >0.94 for charger @230V input.
c. With MCU controller, Precharge-CC-CV-Cutoff 4-stage charge method.
Protection:
1. Short circuit protection: when the output of charger is shorted, the charger will close output automatically without any damage.
2. Reverse polarity protection: when the output is connected to a battery reversely, the charger will close output automatically without any damage.
3. Overheating protection: the internal temperature exceeds 80 ℃, the charger will close output automatically.
