Abstract:
Provided is a system method for periodically charging a sub-battery for an electric vehicle. In this method, an SOC self-discharge rate of the sub-battery is calculated. An LDC output voltage and a charging time of the sub-battery are set using the SOC self-discharge rate of the sub-battery and information received from an IBS. It is determined whether or not an SOC of a main battery is equal to or greater than a set value. Periodic charging is performed on the sub-battery through an operation of an LDC when the SOC of the main battery is equal to or greater than the set value.
