EV consists of three major components motors, energy storage/generation, and power converter. EVs use electric motor for locomotion and consume electrical energy stored in the batteries (Chan, 2002). EV never exhaust any pollution while running as conventional vehicles release, which makes EV alone as eco-friendly vehicles (Chan and Chau, 1997).

The energy storage system is the most important component of the electric vehicle and has been so since its early pioneering days. This system can have various designs depending on the selected technology (battery packs, ultracapacitors, etc.).
The EV is assumed to be connected within this system, permitting the DC charger to draw the accumulated energy from the ESS, efficiently transmitting it to the EV’s battery. More energy is generated and stored at higher solar irradiance levels, so more power is available for EV battery charging.
