Abstract
An energy management system for a vehicle, which assigns profiles to a plurality of energy converters, such as electric motors for traction drive or heating systems, receives requests for mechanical energy or thermal energy and selects energy converters on the basis of the respective profile in order to fulfil the requests. The energy management system can additionally define operating parameters for the selected energy converters. The profiles can be adapted to the operating state of the vehicle and to an environment of the vehicle. The profiles can further be adapted by machine learning.
Claims18
An energy management system for a vehicle comprising:
- a source of electrical energy;
- a multitude of energy converters configured to convert electrical energy from the source of electrical energy into at least one of mechanical energy or thermal energy, wherein the multitude of energy converters includes at least one electric motor for a traction drive of the vehicle;
- wherein
- each energy converter of the multitude of energy converters is assigned a profile which indicates the suitability of the respective energy converter for providing mechanical energy and for providing thermal energy;
- the energy management system is configured to:
- receive requests for mechanical energy and requests for thermal energy,
- select at least one of the energy converters of the multitude of energy converters based on the requests and the respective profile, and
- generate at least one control signal containing information to use the selected at least one energy converter to fulfil the requests.
