Abstract

An electric power supply system includes: a high-voltage battery; a low-voltage battery having a nominal voltage lower than that of the high-voltage battery, the low-voltage battery being electrically connected to a load; a first converter electrically connected between the high-voltage battery and the low-voltage battery, the first converter being configured to perform voltage conversion between the high-voltage battery and the low-voltage battery; a second converter electrically connected between the high-voltage battery and the low-voltage battery, the second converter being configured to perform voltage conversion between the high-voltage battery and the low-voltage battery, the second converter having rated electric power lower than that of the first converter; and a control device that controls operations of the first converter and the second converter. The control device can selectively execute a plurality of operation modes depending on a total value of output currents of the first converter and the second converter.
