A Technical Research Report: The Electric Vehicle
holms.faculty.writing.ucsb.eduThe electric vehicle operates on an electric/current principle. It uses a battery pack (batteries) to provide power for the electric motor. The motor then uses the power (voltage) received from the batteries to rotate a transmission and the transmission turns the wheels [3].
