The present invention prevents electricity from passing through two relays simultaneously at the time of a collision. A first relay (21) and a second relay (22), which are two-contact movable relays that connect/disconnect a high voltage circuit (8), are arranged according to the present invention. When arranging the first relay (21) and the second relay (22) in this travel motor power supply system for an electric vehicle, the directions in which a first movable contact (21b) and a second movable contact (22b) move when connecting/disconnecting are arranged so as to be mutually opposite directions, and one relay from among the first relay (21) and the second relay (22) is oriented such that the movable contact separates from the fixed contacts in a direction in which a greatest acceleration input is applied at a time of a collision. |
