Original Abstract Submitted
An electric work vehicle includes a battery, an inverter to convert output from the battery to AC power, a motor drivable by the converted AC power, a travel device drivable by the motor, a controller configured or programmed to control a current flowing through the motor by operating the inverter in accordance with rotational speed information indicative of a rotational speed of the motor and a required rotational speed for the motor, a DC/DC converter to convert an output voltage of the battery to a voltage applicable to the controller, and a current limiter to limit the current flowing through the motor when a temperature of the inverter is higher than a predetermined temperature. The controller is configured or programmed to limit the current flowing through the motor when at least one temperature of the inverter, the motor, or the DC/DC converter is higher than a predetermined temperature.
