Claim:
1. An electric vehicle, comprising: a first direct current (DC) power supply; a second DC power supply; a voltage converter configured to perform bidirectional voltage conversion between an output electric path and one or both of the first and second DC power supplies, while allowing switching of an operating mode between a serial operating mode in which the first and second DC power supplies are connected in series relative to the output electric path, and a parallel operating mode in which the first and second DC power supplies are connected in parallel; a temperature sensor configured to detect a temperature of each of the DC power supplies; and a control unit configured to switch the operating mode of the voltage converter, wherein the control unit switches the operating mode of the voltage converter to the parallel operating mode when the temperature of one of the DC power supplies detected by the temperature sensor is equal to or higher than a predetermined upper threshold value or equal to or lower than a predetermined lower threshold value.
