US 10,118,501 B2 · Control method and system for charging high voltage battery of vehicle

Abstract

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.
