Electric and hybrid vehicles design fundamentals pdf
Crc press electric and hybrid vehicles design fundamentals - i. hu…A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine to drive an electric generator that powers an electric motor , e. Other means to store energy include pressurized fluid in hydraulic hybrids. The basic principle with hybrid vehicles is that the different motors work better at different speeds; the electric motor is more efficient at producing torque, or turning power, and the combustion engine is better for maintaining high speed better than typical electric motor. Switching from one to the other at the proper time while speeding up yields a win-win in terms of energy efficiency , as such that translates into greater fuel efficiency , for example. Mopeds , electric bicycles , and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and the rider's muscles.
