Provided is an electric automobile that, without suddenly obstructing the operation of the vehicle, manages the temperature of a motor and can swiftly take appropriate countermeasures. This electric automobile is provided with: a motor (6) that drives wheels (2); and a control device containing an inverter (31) that controls the motor (6). A temperature sensor (Sma(Sia)) is provided that detects the temperature (Tic) of the inverter (31) or the temperature (Tmc) of the motor coil (78) of the motor (6), and a control means (95(102)) is provided that, when the temperature (Tmc(Tic)) detected by the temperature sensor (Sma(Sia)) exceeds an inverter temperature threshold or a motor coil temperature threshold, applies a limit to the current command applied to the inverter (31) or reduces the current value of the motor (6) until dTmc/dt (dTic/dt), which is temperature (Tmc(Tic)) differentiated with respect to time (t), becomes 0 or less. |
