The electric car is more than a vehicle that runs on batteriesIt differs from the conventional car in many waysOne essential difference is the absence of the internal combustion engineAnother is the lack of a fuel tank and an exhaust pipeThere is another big difference - the way power is transmitted to the wheel to move the car.

The electric car moves by transfer of power from the batteries to the controller then to the motorThe motor is the internal combustion equivalent of the electric carIt is the main component that causes movementThe electric car does not use a flywheel so there is a challenge for the designers as to how power can be transmitted to the wheel at varying speedsThe transmission needs to get a special device that will enable it to adapt to changing speeds.
