Method for optimizing the use of a device connected to an electric machine energy storage

It is proposed a method for optimizing the use of the connected to the electrical machine of a parallel hybrid vehicle energy storage device, whose different for the operation of the energy store lower limits are defined or specified in the frame, wherein for the execution of electric power is required for each vehicle function, a priority is assigned, wherein different priorities are assigned to different lower energy-storage-limits such that the energy-storage-limits are reduced for higher priority vehicle functions, so that these are carried out within the physical limits of the energy store.
