Abstract

A method for controlling low-voltage battery charging may include determining a state-of-charge (SOC) of a low-voltage battery based on a voltage of the low-voltage battery. A base charging voltage is set according to the SOC of the low-voltage battery. A charging voltage of the low-voltage battery is set based on the base charging voltage, a vehicle operation mode, and a SOC of a high-voltage battery.
