Heres another type of hybrid technology you might not have heard of: Hydraulic Hybrid.

Chrysler and the EPA announced today they are working together to determine the possibility of adapting a hydraulic hybrid system for large passenger cars and light-duty vehicles.

The hydraulic hybrid system, developed by the EPAs lab in Ann Arbor, is currently used in refuse trucks and delivery trucks, including some UPS vehicles. Chrysler hopes to reduce the size and complexity of the hybrid system.

The research project will focus on adapting the hydraulic hybrid system to a Chrysler Town & Country minivan equipped with a 2. 4-liter, four-cylinder engine. Components of the hydraulic hybrid system include a small engine pump, an electric motor and a two-speed automatic transmission. Fluid for the system will be stored in a high-pressure accumulator.

The system produces power with engine torque driving a hydraulic pump that charges the high-pressure accumulator up to 5,000 psi. The high-pressure accumulator delivers the pressure energy to the axle hydraulic motor, giving the vehicle power to drive the wheels. The engine shuts off if the accumulator charge is sufficient to drive the motor.
