An electric drive vehicle which is capable of performing a bidirectional voltage conversion between two DC power supplies and a rotary electric machine, and a connection switch between a series connection and a parallel connection of the two power supplies with respect to the rotary electric machine. The electric drive vehicle can supply electric power without a delay in response to a change in a load request. A controller sets the connection between the two power supplies to the parallel connection when an estimated value of an output electric current in accordance with a torque command to the rotary electric machine exceeds a tolerable electric current value of at least one of the two power supplies.
