How Electric Cars Work. An electric car is a car powered by an electric motor rather than a gasoline engine. From the outside, you would probably have no idea that a car is electric. In most cases, electric cars are created by converting a gasoline-powered car, and in that case it is impossible to tell.
How Do All-Electric Cars Work? All-electric vehicles (EVs) have an electric motor instead of an internal combustion engine. The vehicle uses a large traction battery pack to power the electric motor and must be plugged in to a charging station or wall outlet to charge. Because it runs on electricity, the vehicle emits no exhaust from a tailpipe and does not contain the typical liquid fuel components, such as a fuel pump, fuel line, or fuel tank.
The electric motor is used to drive the car’s wheels and, if two motors are used with one being placed on each axle, then electric cars can have four-wheel drive too.
How Electric Cars Work. The controller takes power from the battery and passes it on to the electric motor. Before passing the current to motor, the controller converts the 300V DC into a maximum of 240 volts AC, 2 phase power which is suitable for motor. The electric motor then converts electrical energy to mechanical energy.
Battery electric cars have the added benefit of home recharging. A 240-volt outlet, similar to those used for clothes dryers, can charge a vehicle overnight. Fully-charged, most battery electric cars have a driving range of between 70 to 100 miles, well within the day-to-day range requirements of most Americans, though some BEVs can go up to 265 miles on a single charge.
Now, in a typical car that isn’t electric, there is both an engine and an alternator. The battery powers the engine, which powers the gears and wheels. The rotation of the wheels is what then powers the alternator in the car and the alternator recharges the battery.
