Abstract
The present invention relates to an electric vehicle, and to a method for managing the charging of an auxiliary battery for an electric vehicle. The electric vehicle according to the present invention comprises: a high voltage battery for driving the electric vehicle; an auxiliary battery for supplying a plurality of electronic loads with driving power; a converter converting the voltage of the high voltage battery to a voltage required by the electronic loads via PWM switching; and a current detection unit for detecting the output current of the converter wherein the converter includes a converter control unit for reducing the output voltage of the converter when the energy required by the loads, based on the current detected by the current detection unit, is greater than the rated capacity of the converter. Accordingly, energy supplied to the loads can be handled by the converter and the auxiliary battery so as to enable the safe operation of an electric vehicle system.
