A hybrid vehicle comprises an internal combustion engine, a traction motor, a starter motor, and a battery bank, all controlled by a microprocessor in accordance with the vehicle's instantaneous torque demands so that the engine is run only under conditions of high efficiency, typically only when the load is at least equal to 30% of the engine's maximum torque output. In some embodiments, a turbocharger may be provided, activated only when the load exceeds the engine's maximum torque output for an extended period; a two-speed transmission may further be provided, to further broaden the vehicle's load range. A hybrid brake system provides regenerative braking, with mechanical braking available in the event the battery bank is fully charged, in emergencies, or at rest; a control mechanism is provided to control the brake system to provide linear brake feel under varying circumstances.

Hybrid vehicle configuration

A hybrid vehicle comprising an internal combustion engine controllably coupled to road wheels of the vehicle by a clutch, and having a turbocharger that is operated only when extra power is needed for a extended time, a traction motor coupled to road wheels of said vehicle, a starting motor coupled to the engine, both motors being operable as generators, a battery bank for providing electrical energy to and accepting energy from said motors, and a microprocessor for controlling these components, is operated in different modes, depending on its instantaneous torque requirements, the state of charge of the battery bank, and other operating parameters. The mode of operation is selected by the microprocessor in response to a control strategy.

A stand-by uninterruptible power supply which provides for extended backup time and/or an increase in power rating for stand-by power supply applications. The uninterruptible power supply also has a waveshape circuit for rating the power capacity of the supply. The waveshape circuit provides a more effective way of rating the capacity of the power supply so that different supplies may be easily compared with little confusion.
