Partially solar powered full electric vehicles

Electric Vehicles (EV) are known to have three times more energy efficient than petroleum internal combustion engine (ICE) vehicles. This is true if we do not consider electricity generation, transmission and vehicle battery charging efficiency. ICE vehicles have various vendor-specific technologies regarding fuel efficiency including engines, transmissions and their matching. EV, on the other hand, fuel efficiency is largely dependent on the vehicle weight thanks to simplified drivetrain such as direct drive without a transmission. Nevertheless, true energy efficiency of EV should be justified by the source of electricity. This paper introduces a custom, light-weight EV prototype for partial solar powered EV. We demonstrate the custom energy-efficient EV prototype and possibility of partially solar-powered EV.
