차량제어부에서 저전압컨버터를 이용하여 고전압배터리를 충전하는 단계; 차량제어부에서 고전압배터리의 충전진행 중 저전압컨버터의 전류 및 온도를 포함하는 저전압컨버터의 상태정보를 감지하는 단계; 및 감지한 저전압컨버터의 상태정보가 기설정된 컨버터디레이팅 조건을 만족하는 경우 차량제어부에서 고전압배터리 충전전류를 디레이팅(derating)하는 단계;를 포함하는 차량의 고전압배터리 충전 제어방법이 소개된다.
a control method for charging a high voltage battery of a vehicle includes charging, by a vehicle controller, the high voltage battery using a low voltage DC-DC converter The state information. of the low voltage DC-DC converter, which includes the current and the temperature of the low voltage DC-DC converter, is sensed by the vehicle controller while charging the high voltage battery. The charging current of the high voltage battery is derated by the vehicle controller when the sensed state information of the low voltage DC-DC converter satisfies a converter derating condition.
