The three different types of power sources are the battery, the starter, and the alternator.
The battery is the most common type of power source in cars. It’s a chemical reaction that generates electricity when it is charged with a circuit. The battery has a limited life span and needs to be recharged over time, especially if it is not used for long periods of time.
The starter motor is what turns the engine over to get it running when you turn the key in your car. It’s an electric motor that gets its energy from electricity stored in a battery or from another power source like an alternator or dynamo.
The starter motor can also run on its own internal energy source, like gasoline or diesel fuel, but this makes it noisier and less efficient. The alternator provides electricity by converting rotational kinetic energy from the engine’s crankshaft into electric current.
