A driving device includes a motor; a power storage device; a first boost converter configured to exchange power by voltage conversion between a power storage device side and a motor side; a second boost converter connected to the first boost converter in parallel and configured to exchange power by voltage conversion between the power storage device side and the motor side; and an electronic control unit configured to control the first boost converter and the second boost converter. The electronic control unit controls the first boost converter and the second boost converter such that the loss of each of the first boost converter and the second boost converter is not minimized during an excessive power input in which power to be input to the power storage device from the motor side is greater than an input limit of the power storage device.
