An electric vehicle comprises an electric motor for generating driving power for moving a vehicle body of the electric vehicle; a battery unit for supplying electric power to the electric motor; a charging connector connected to an outside electric power supply for supplying the electric power to be charged; a main controller for controlling switching between a first connection state in which the battery unit is connected to the electric motor and a second connection state in which the battery unit is connected to the charging connector; and a relay for opening and closing a power supply path from the low-voltage battery to the main controller; wherein a relay opens the power supply path to cut off electric power supply to the main controller for a specified time, when the relay switches one of the first connection state and the second connection state to the other connection state.
