A VERY LOW EMISSION HYBRID ELECTRIC VEHICLE INCORPORATING AN INTEGRATED PROPULSION SYSTEM INCLUDING A HYDROGEN POWERED INTERNAL COMBUSTION ENGINE AND A HIGH POWER NI-MH BATTERY PACK

摘要

A very low emission hybrid electric vehicle incorporating an integrated propulsion system which includes a hydrogen powered internal combustion engine, 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 > 1,420 - 16E, 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.
