Abstract: A very low emission hybrid electric vehicle incorporating an integrated propulsion system which includes a fuel cell, a metal hydride hydrogen storage unit, an electric motor, high specific power, high energy density nickel-metal hydride (NiMH) batteries, and preferably a regenerative braking system. The nickel-metal hydride battery module preferably has a peak power density in relation to energy density as defined by: P>1,375?15E, where P is greater than 600 Watts/kilogram, where P is the peak power density as measured in Watts/kilogram and E is the energy density as measured in Watt-hours/kilogram.

Abstract: A hybrid electric vehicle drive system comprising a combustion engine, an electric motor and at least one nickel metal hydride battery module forming a power source for providing electric power to the electric motor, the at least one nickel metal battery module having a peak power density in relation to energy density as defined by: P>1,375?15E where P is the peak power density as measured in Watts/kilogram and E is the energy density as measured in Watt-hours/kilogram.

Abstract: A hybrid vehicle having a hydrogen powered internal combustion engine employing a cylinder deactivation strategy during idle or light load conditions. A continuous stream of air is supplied to the hydrogen internal combustion engine. A control system responsive to engine speed and accelerator pedal position calculates a specific amount of hydrogen to inject into the continuous air stream. The resulting stream is combusted in the engine to provide power to the vehicle. During idling or light load conditions, the hydrogen supply to one or more cylinders may cease while maintaining the flow of air to the cylinders. A rechargeable battery and an electric motor receiving power from the battery are used to supplement the hydrogen powered internal combustion engine.
