PROJECT : DESIGN OF ELECTRIC VEHICLE EV HISTORY & THERORY: Electric motive power started in 1827, when Hungarian priest Ányos Jedlik built the first crude but viable electric motor, provided with stator, rotor and commutator; the next year, he used it to power a tiny car. In 1835, professor Sibrandus Stratingh…

What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Mapped Model: Model uses a set of steady-state lookup tables to characterize engine performance. The tables provide overall engine characteristics, including actual torque, fuel flow rate, BSFC,…
