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>1,420−16E where P is the peak power density as measured in Watts/kilogram and E is the energy density as measured in Watt-hours/kilogram.
Claims34
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 said electric motor, said at least one nickel metal battery module having a peak power density in relation to energy density as defined by:
- P>1,420−16E
- where P is the peak power density as measured in Watts/kilogram and E is the energy density as measured in Watt-hours/kilogram.
A hybrid electric vehicle incorporating an integrated propulsion system comprising:
- a power system comprising a combustion engine and an electric motor,
- nickel metal hydride batteries configured for maximum peak power density and high energy density coupled to said power system, and
- power controlling means governing said power system and configured for optimum operation of said combustion engine and said electric motor.
The hybrid electric vehicle incorporating an integrated propulsion system of claim 25, where said negative electrode or the surface of said reduced thickness separator facing said negative electrode has a uniform distribution of hydrophobic material to increase gas recombination and reduce cell pressure.
The hybrid electric vehicle incorporating an integrated propulsion system of claim 26, where said hydrophobic material comprises a 1% aqueous solution of polytetrafluoroethylene.
