发明名称 SYSTEM AND METHOD OF CONTROLLING LOW-VOLTAGE DC/DC CONVERTER FOR ELECTRIC VEHICLE
摘要 A system and method of controlling a low-voltage DC/DC converter for an electric vehicle that include a battery sensor that senses information regarding a low-voltage battery during a stop of the electric vehicle for each first period when the electric vehicle stops and a controller that operates a low-voltage DC/DC converter to charge the low-voltage battery for a predefined time when an error occurs in the battery sensor. In addition, the controller determines a charge time of the low-voltage battery based on first SOC values of the information regarding the low-voltage battery sensed for each first period when no error in the battery sensor is detected and operates the low-voltage DC/DC converter for the determined charge time to charge the low-voltage battery.

主权项 1. A method of controlling a low-voltage DC/DC converter for a vehicle, comprising: sensing information, by a battery sensor, regarding a low-voltage battery during a stop of the vehicle for each first period when the vehicle stops; operating, by a controller, a low-voltage DC/DC converter to charge the low-voltage battery for a predefined time when an error occurs in the battery sensor to sense the information of the low-voltage battery during the stop of the vehicle; determining, by the controller, a charge time of the low-voltage battery based on first SOC values of the information regarding the low-voltage battery sensed for each first period when error in the battery sensor is not detected; and operating, by the controller, the low-voltage DC/DC converter for the determined charge time to charge the low-voltage battery.
