Abstract:
1. A motor vehicle, comprising: at least one electric motor; an energy storage device for providing drive energy for the electric motor; a plug connector connected to the energy storage device for connection to a current source; and a control means for controlling flow of current between the current source and the energy storage device, wherein the control means permits a flow of current from the energy storage device to the current source, and the control means includes a device for detecting an amount of charge in the energy storage device and interrupts the flow of current from the energy storage device to the current source if a predeterminable threshold value of a remaining residual charge amount is reached, wherein the control means is programmable to allow discharge of the energy storage device by the flow of current from the energy storage device to the current source only during a predeterminable time period that is set by a user.
