A main relay protection device includes a motor generator, a rechargeable driving battery, an externally-coupled charger, a main relay, a charging bus bar, a charging relay, a main relay temperature sensor, and a controller. The motor generator drives a vehicle. The battery supplies power to the motor generator. The charger charges the battery. The main bus bar is disposed between the battery and the motor generator. The main relay is disposed in the main bus bar. The charging bus bar is disposed between the main bus bar and the charger. The charging relay is disposed in the charging bus bar. The sensor is configured to detect a temperature of the main relay. The controller performs ON-control on the charging relay in a state where the main relay is turned on, if the detected temperature of the main relay is higher than or equal to a preset heat radiation starting threshold.
