Essentially, EV is as same as the Prius HS which belongs to power spit devices using double motors. he degree of hybridization (DOH) definition of EV based hybrid vehicle as well as the method of minimizing EV power is derived to minize the power of inner and outter motor when vehicle performance is satisfied. It is proved in this paper that EV is favored in the full-hybrid application. Simulaiton result shows that perfermance of EV based HEV designed as the proposed method is equivalent to a Prius.
