Abstract
A vehicle driven by an electric motor includes a drive unit (16) with at least one electric motor (18), with at least one energy storage device (22) permanently installed in the vehicle and an actuating unit (24) for controlling the flow of energy between the at least one electric motor (18) and the at least one energy storage device (22) permanently installed in the vehicle. An interface (30) has with at least one terminal area (32, 34, 36) for a replaceable energy storage device (38, 40).
Claims20
A vehicle driven by an electric motor, the vehicle comprising:
- a drive unit comprising at least one electric motor;
- at least one energy storage device permanently installed in the vehicle;
- an actuating unit for controlling a flow of energy between the at least one electric motor and the at least one energy storage device permanently installed in the vehicle;
- an interface comprising a plurality of terminal areas, each terminal area being provided for a replaceable energy storage devices;
- a plurality of replaceable energy storage devices, each replaceable energy storage device being connected to one of the terminal areas, wherein the actuating unit is configured to influence a flow of energy between the at least one electric motor and the replaceable energy storage devices connected to the terminal areas, wherein the actuating unit is configured to influence a flow of energy from the replaceable energy storage devices to the at least one electric motor such that the replaceable energy storage devices are run down sequentially, wherein the actuating unit is further configured to influence a flow of energy from the energy storage device permanently installed in the vehicle and the replaceable energy storage devices to the at least one electric motor in a traction mode such that first the replaceable energy storage devices are run down and, only if the replaceable energy storage devices can no longer supply the at least one electric motor, the energy storage device permanently installed in the vehicle is accessed for supplying energy to the at least one electric motor.

- an energy storage device permanently installed in the vehicle;
- an actuating unit for controlling a flow of energy between the at least one electric motor and at least the energy storage device permanently installed in the vehicle;
- a plurality of replaceable energy storage devices;
- an interface comprising a plurality of terminal areas, each of the terminal areas being associated with one of the replaceable energy storage devices, each of the replaceable energy storage devices being connected to one of the terminal areas, wherein the actuating unit is configured to:
- control a flow of energy between the at least one electric motor and the replaceable energy storage devices;
- control a flow of energy from the replaceable energy storage devices to the at least one electric motor such that energy from each of the replaceable energy storage devices is delivered to the at least one electric motor one after one another prior to energy from the energy storage device permanently installed in the vehicle being supplied to the at least one electric motor;
- provide the energy from the energy storage device permanently installed in the vehicle to the at least one electric motor only if the replaceable energy storage devices can no longer supply the at least one electric motor.
