Abstract
A motor vehicle is provided having a control device, an electronic power unit and an energy storage system including first and second electric energy storage devices connectable in parallel so as to have a common base voltage at respectively different states of charge. The base voltage is substantially adjustable by the electronic power unit. A predictive energy management system executed by the control device determines a predefined setpoint value of a base voltage as a function of a predicted charge balance of the energy storage device.
