Abstract
A method for operating a vehicle in particular a commercial vehicle having electric energy storage and an electric driving machine, includes determining an absorbable amount of energy of the electric energy storage, determining a driving route drivable by the vehicle at least partially in an overrun mode, and determining a recuperation power by which the vehicle may by operated along the driving route and/or determining a target speed at which the vehicle is to be driven on the driving route, such that at the end of the driving route the energy content of the energy storage has been increased by the determined absorbable amount of energy. Also provided is a device, a computer program product and a storage medium for the energy management of an electrically driven vehicle as well as such vehicle.
Claims20
A method for operating a vehicle comprising an electric energy storage and an electric driving machine, the method comprising:
- determining an absorbable amount of energy of the electric energy storage of the vehicle, wherein the vehicle further comprises a control device comprising a data processing device that performs the determining via at least one interface configured to receive data of the vehicle;
- and
- controlling the electric driving machine by the control device and by at least one interface configured for delivering control data to the vehicle so as to supply an amount of recuperation energy to the electric energy storage during an entirety of a driving route driven by the vehicle, such that at the end of the driving route, but not before, energy content of the electric energy storage has been increased by the absorbable amount of energy and such that the entirety of the driving route is driven solely by a permanent braking effect generated by the electric driving machine based on recuperation.
A vehicle comprising:
- a battery;
- an electric driving machine configured to provide a permanent braking effect on the vehicle by charging the battery with recuperation energy of the electric driving machine;
- and
- a data processing unit configured to control the electric driving machine to provide the permanent braking effect on the vehicle along an entire route by ensuring that the battery is prevented from charging to a certain level until the vehicle is at the end of the route and to ensure that the entirety of the driving route is driven solely by a permanent braking effect generated by the electric driving machine based on recuperation.
A vehicle comprising:
- an electric driving machine;
- an electric energy storage;
- and
- a control device comprising a data processing device, wherein the control device is configured to control the electric driving machine to supply an amount of recuperation energy to the electric energy storage along an entirety of a driving route, such that a predetermined energy level of the electric energy storage is not reached until an end of the driving route and to ensure that the entirety of the driving route is driven solely by a permanent braking effect generated by the electric driving machine based on recuperation.
