If an alternator works fine to charge a battery, why don’t we use one in an Electric Car? The two main reasons are: 1) An E.V. doesn’t have an engine 2) There’s a BETTER device to use than an alternator.

The purpose of the alternator is to produce AC electricity from an internal combustion engine. EVs don’t have an internal combustion engines. Instead they have this huge electric motor that can generate electricity while slowing down. Alternators ...

Consumers (starter motor, spark plugs, fans, windows, lights, radio, etc.). The alternator will charge the battery when the car is running, the charge being managed by very basic control electronics. While the engine is running, the consumers draw power from the alternator. While it is stopped, they will be consuming from the battery.

Why not just leave the original regulator in place and use the alternator as she was designed? Replacing the field coils does sound like a lot of bother and a loss of a useful function. Report ...

The alternator does not produce electricity for free, it actually slows down the motor. And the energy that the motor loses due to that is more than the energy produced by the alternator. If you're wondering why they don't make an electric car with a gasoline engine to recharge the battery, they've actually done that: Chevy Volt is an example.

The first car to come standard with an alternator was, believe it or not, the 1960 Plymouth (though, at first, they wanted Valiant to be its own marque) Valiant. Some of the more immediately ...

Whatever your prime mover (water, wind, donkey on a treadmill) the alternator from a car will waste 30–50% of the input power as heat, especially at the upper end of the current range. You can ameliorate that by allowing the alternator to put out more than 12 volts.

An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators. As silicon diode rectifiers became widely available and affordable, the alternator gradually replaced the dynamo. This was encouraged by the increasing electrical power required for cars in this period, with increasing loads from larger headlamps, electric wipers ...
