CA 2281537

A hybrid electric vehicle drive system comprising a combustion engine (79), an electric motor (76) and at least one nickel-metal hydride battery module (75) having an internal resistance effective to provide a peak power density in relation to an energy density as defined by: P > 1,375 - 15E, 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. The at least one nickel-metal hydride battery module provides an energy density and a power density for proper hybrid electric vehicle operation.

Cette invention se rapporte à un système d'entraînement de véhicule électrique hybride, comprenant un moteur à combustion (79), un moteur électrique (76) et au moins un module (75) de batterie hybride nickel-métal constituant une source de puissance destinée à fournir l'énergie électrique au moteur électrique (76). Le ou les modules de batterie hybride nickel-métal comportent une densité de puissance crête, par rapport à la densité d'énergie, définie par la relation: P > 1420 - 16E, où P représente la densité de puissance crête mesurée en Watts/kilogramme et E représente la densité d'énergie mesurée en Watt-heures/kilogramme.
