Tri-Energy Source Hybrid Vehicle Powertrain

Technology Benefits

Ability to split power among three energy sources Additional flywheel SESS is low cost, low weight, high power and compact

Technology Application

Alternative energy vehicle powertrains and energy systems

Detailed Technology Description

Increasing fuel costs and tightening emissions regulations have pushed researchers in the automotive industry to develop alternative energy technologies that can replace conventional ICE systems. While some researchers focus on singular alternative energy vehicle powertrains such as pure electric powertrains, many researchers see the benefit in developing hybrid powertrains that incorporate ICE and alternative energy sources. Researchers at the University of California, Davis have developed a TES hybrid vehicle powertrain consisting of three different propulsion systems including: (i) an ICE; (ii) an electric motor and battery and; (iii) a flywheel and CVT. The primary and secondary propulsion systems, consisting of an ICE and electric motor, provide continuous power to the drive train while operating at nearly optimal states. The third propulsion system encompasses a dedicated short-term energy storage system (SESS), designed for load leveling and power surges.
