Vehicle

A vehicle includes: a rotating electrical machine configured to drive the vehicle; a high-voltage power source configured to supply electricity for driving the rotating electrical machine; main and backup low-voltage power sources; a normal load configured to operate on the electricity supplied from the main low-voltage power source; a critical load configured to operate on the electricity supplied from the backup low-voltage power source; and a floor panel. The critical load includes an auxiliary load for controlling, braking, steering, or acquiring external information of the vehicle. A central tunnel extending in a central part of the vehicle in the vehicle width direction along the vehicle length direction is formed in the floor panel. The low-voltage power sources are placed right above the floor panel. One of them is placed to one side of the central tunnel in the vehicle width direction, and the other one the other side.
