This mode is called charge depletion mode where the battery is depleted. The electric motor works alone to provide the torque required to move the vehicle. As far as the working is concerned, the PHEVs use both the ICE and the electric motor. The series of Li-ion battery ensures a bigger life span and increases the overall efficiency of the electric motor. There can either be a single large battery or a series of Li-ion battery. In a plug-in hybrid electrical car, electrical motor and combustion engine work in perfect harmony to fulfill the needs of the vehicle. The plug-in hybrid electric vehicles mainly comprises of four parts-Internal combustion engine, no emission electric motor, high performance series of rechargeable battery, and transmission system. Plug-in electrical vehicles include Toyota Prius, Audi A3 e-tron, Lexus, Tesla Model 3. Although the history of PHEVs go way back in time, the development for commercial use took place after 2002.

Henry Ford with the initiation of mass production of gas-powered vehicles brought prices down and ensured their demise. The above normal cost, low top speed, and short range electric vehicles saw their decline with the invention of electric starters by Charles Kettering. Thomas Parker built the first practical electric car in the year 1895. The first model electric vehicle is attributed to various people in the year 1828, Anyos Jedlik invented an electric motor and created a model car. The history of electric vehicles go back to the late eighteenth and early nineteenth century. But to know more about the plug-in hybrid, we must know when and where it all started. It is as energy conserving as the electric vehicles and as efficient as the conventional vehicles. Plug-in hybrid electric vehicles are nothing but a mixture of an electric vehicle and a conventional vehicle.
