Enhanced Energy Efficiency Methods of Hybrid Systems

A hybrid system that uses two motive power sources and utilizes their advantages is expected to have a significant effect on enhancing the energy efficiency of automobiles and to reduce emissions of air polluting substances. The Laboratory is conducting research into methods to reduce energy consumption and to correctly assess fuel consumption performance with an electric-hybrid motive power system that runs the vehicle by both a motor and engine while storing electric energy in batteries and a super capacitor.

Series Hybrid Electric Power System

(1)The engine generates electric power and the motor drives the vehicle.
(2)The cruising distance of electric vehicles can be increased significantly.
(3)A compact engine runs at a constant speed to reduce fuel consumption
and emission of air polluting substances.
