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.
Claims15
A hybrid electric vehicle drive system, comprising:
- a combustion engine;
- an electric motor;
- and
- at least one nickel metal hydride battery module providing electric power to said electric motor, said at least one nickel metal hydride battery module having an internal resistance effective to provide a peak power density in relation to an energy density as defined by:
- P>1,420−16E, with P 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.
A hybrid electric vehicle incorporating an integrated propulsion system, comprising:
- a power system comprising:
- a combustion engine, and
- an electric motor;
- and
- at least one nickel-metal hydride battery module coupled to said power system and providing electric power to said electric motor, said battery module having an internal resistance effective to provide a peak power density in relation to an energy density as defined by:
- P>1,420−16E, with P 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.
