Abstract
A junction block is provided to a vehicle and is interposed between a motor and each of a first battery and a second battery connectable to each other to electrically connect the first battery, the second battery, and the motor. The junction block includes a first path that charges only the first battery and is provided with a first current sensor, a second path that charges only the second battery, a third path that charges the first battery and the second battery, and a second current sensor that is provided at a portion where the second path and the third path overlap each other and do not overlap the first path, and measures a current flowing through the second battery.
