Energy storage specification requirements for hybrid-electric vehicle

PDF Version Also Available for Download.

Description

A study has been made of energy storage unit requirements for hybrid-electric vehicles. The drivelines for these vehicles included both primary energy storage units and/or pulse power units. The primary energy storage units were sized to provide ``primary energy`` ranges up to 60 km. The total power capability of the drivelines were such that the vehicles had 0 to 100 km/h acceleration times of 10 to 12 s. The power density requirements for primary energy storage devices to be used in hybrid vehicles are much higher than that for devices to be used in electric vehicles. The energy density and ... continued below

Description

A study has been made of energy storage unit requirements for hybrid-electric vehicles. The drivelines for these vehicles included both primary energy storage units and/or pulse power units. The primary energy storage units were sized to provide ``primary energy`` ranges up to 60 km. The total power capability of the drivelines were such that the vehicles had 0 to 100 km/h acceleration times of 10 to 12 s. The power density requirements for primary energy storage devices to be used in hybrid vehicles are much higher than that for devices to be used in electric vehicles. The energy density and power density requirements for pulse-power devices for hybrid vehicles, are not much different than those in an electric vehicle. The cycle life requirements for primary energy-storage units for hybrid vehicles are about double that for electric vehicles, because of the reduced size of the storage units in the hybrid vehicles. The cycle life for pulse-power devices for hybrid vehicles is about the same as for electric vehicles having battery load leveling. Because of the need for additional components in the hybrid driveline, the cost of the energy storage units in hybrid vehicles should be much less (at least a factor of two) than those in electric vehicles. There are no presently available energy storage units that meet all the specifications for hybrid vehicle applications, but ultracapacitors and bipolar lead-acid batteries are under development that have the potential for meeting them. If flywheel systems having a mechanical system energy density of 40 to 50 W{center_dot}h/kg and an electrical system power density of 2 to 3 kw/kg can be developed, they would have the potential of meeting specifications for primary storage and pulse power units.
