On-board charger uses a 2-converter system which consists of the PFC circuit and the DC/DC converter. It improves charging efficiency, full-charge accuracy and service life of the Li-ion battery. On-board charger judges if external power supply is 100 V or 200 V, and automatically switches to the charging appropriate for the power supply.
NOTE:
PFC (Power Factor Correction) circuit is a power factor improvement circuit. It is a device for converting AC power (input from external source) to DC power efficiently.
