A vehicle includes an electric motor, a direct current power source, and an inverter operatively connected to the direct current power source and the electric motor. The inverter is configured to convert direct current from the power source to alternating current and to transmit the alternating current to the electric motor. The inverter is characterized by an on status and an off status. A controller is operatively connected to the inverter and is configured to control whether the inverter is on or off. The controller is configured to selectively cause the inverter to enter a mode of operation in which the inverter cycles between being on and off.
