CHARGING CONTROL METHOD FOR PLUG-IN HYBRID ELECTRIC VEHICLE AND ELECTRIC VEHICLE

摘要

The present invention relates to a battery charging control method for eco-friendly vehicles and, more particularly, to a charging control method which can achieve high charging efficiency by improving an output control method of a power factor correction (PFC) converter during battery charging using a slow charger in electric vehicles or plug-in hybrid vehicles. To achieve the objective of the present invention, the charging control method for plug-in hybrid vehicles and electric vehicles having a slow charger including a PFC converter and a DC-DC converter comprises the steps of: sensing a battery voltage during charging by a voltage detection unit; calculating a target value for controlling an output voltage of a PFC converter from the sensed battery voltage and an available maximum duty value of a DC-DC converter; and controlling the output voltage of the PFC converter according to the calculated target value.
