Abstract
An energy management system for a hybrid internal combustion and electric vehicle provides a highly energy-efficient and yet highly agile hybrid vehicle. The vehicle includes an internal combustion engine, an electric motor/generator and at least one electric storage battery for storing and dispensing energy, all operating in conjunction with an energy storage system including a sensing and control unit and a superconducting magnetic energy storage device. The sensing and control unit is connected to the motor/generator, the battery and the storage device, and has as an input at least one sensor signal representative of a preselected sensed vehicle condition. The sensing and control unit selectably charges the battery at a charging rate compatible with maximum battery efficiency, discharges the battery at a discharging rate also compatible with maximum battery efficiency, causes the storage device to store energy from the motor/generator, and causes the storage device to supply stored energy to the motor/generator, in response to the sensed vehicle condition.
