Abstract: An energy management system for controlling an electrical system comprises data collection components, such as sensors, for providing quantified variables for forming an instantaneous state vector. A time series predictor generates an estimated future vector value in response to the instantaneous state vector. An electrical system manager includes predetermined decision rules invoked in response to the estimated future vector value to adapt the electrical system to expected electrical conditions.

Abstract: The invention is designed for vehicles having two electrical power supply systems and corresponding differentiated voltage level charges and two batteries operating at a first and a second voltage level. A bidirectional voltage converter cooperates with both systems whose input and output stages are galvanically insulated and include a switch. The batteries are connected to said input and output at a first and a second voltage level so that said bidirectional converter can provide a first reduced voltage mode and a second increased voltage mode. The passive components, e.g. the magnetic components and capacitances, of said stages have been chosen to provide an identical transitional behavior in both modes when a disruption occurs in the regulating system either in the charge or the input voltage.
