PROBLEM TO BE SOLVED: To accurately detect grounding of a car body and an electric power source without being accompanied with erroneous detection. SOLUTION: When the grounding of a vehicle body B and the battery pack 4 is detected by comparing an electrostatic capacity between the body B and the battery pack 4 with a prescribed threshold value, an electrostatic capacity of the body is estimated by a battery controller 9, and the threshold value is set based on an estimated electrostatic capacity of the body.
