1. A battery electric vehicle, comprising:

  • a propulsion system, comprising;

    a battery with a DC output,an inverter with a DC input and an AC output, the inverter operative to convert DC power from the battery to provide AC electrical power to the AC output, andan electric motor having an output shaft providing mechanical power To drive at least one wheel for propelling the vehicle using AC power generated by the inverter; and

    a navigation system operative to determine a traveling route for the battery electric vehicle extending from a current vehicle location to a destination location based at least in part on a present state of charge value indicating a remaining amount of energy stored in the battery, where the navigation system preferentially selects low speed routes over higher speed routes in determining the traveling route when the present state of charge value is insufficient to reach the destination location using shortest time or shortest distance routes.
