How Does an Electric Vehicle Work?
1 Answers
Electric vehicles operate on the principle that a battery supplies current, which is then regulated by a power controller to drive the motor's powertrain system, propelling the vehicle forward. An electric vehicle (BEV) refers to a vehicle that uses an onboard power source as its driving force, employs an electric motor to drive the wheels, and meets all the requirements of road traffic and safety regulations. For cars powered by fuel cells, the chemical reaction process in the fuel cell does not produce harmful byproducts, making fuel cell vehicles pollution-free. Moreover, the energy conversion efficiency of fuel cells is 2 to 3 times higher than that of internal combustion engines. Therefore, from the perspectives of energy utilization and environmental protection, fuel cell vehicles represent an ideal mode of transportation.
