How do electric vehicles work? Electric cars use an on-board battery to store electrical energy, which is recharged by connecting it to an electricity supply (usually the 'mains'). When required, energy is drawn from the electric-cells and converted to motive power by the use of one or more electric motors.
Electric motors are used to produce linear or rotary force (torque), and should be distinguished from devices such as magnetic solenoids and loudspeakers that convert electricity into motion but do not generate usable mechanical powers, which are respectively referred to as actuators and transducers.
