Abstract

A motor vehicle is configured to include a first battery; a second battery; a first converter configured to step-down an electric power of the first power line and supply the stepped-down electric power to a second power line with which the second battery is connected; a third battery; a solar charging device configured to generate electric power using sunlight and supply the generated electric power to the third battery; and a second converter configured to transmit electric power accompanied with a change in a voltage between the second power line and a third power line with which the third battery is connected. The motor vehicle of this configuration is configured to provide permission for relief charging that is charging of the third battery using an electric power on a first power line side, when a voltage of the second battery is not lower than a predetermined voltage.
