Understanding electrical: starters, alternators, batteries
Essentially, the foundation of your vehicle's electrical system rests upon these key components: the battery, alternator, and starter. They work together to provide power for starting the engine, generating electricity, and storing electrical energy.
- Starters: The starter is an electric motor that initiates the engine's combustion process. When the driver turns the ignition key or presses the start button, the starter motor engages with the engine's flywheel or flexplate. It then turns the engine over, allowing the combustion process to begin. Once the engine starts, the starter disengages.
- Alternators: Alternators are responsible for generating electrical power while the engine is running. They convert mechanical energy from the engine's rotation into electrical energy. Alternators produce electricity to power the vehicle's electrical systems and accessories, as well as to recharge the battery. They also provide power to the vehicle's ignition system and fuel injection system.
- Batteries: Batteries store electrical energy and provide the initial power required to start the engine. They are rechargeable and supply electrical power when the engine is off or when the alternator cannot meet the electrical demand. Batteries also stabilize the electrical system, ensuring a steady supply of power for the vehicle's electronics and accessories.
Starter vs alternator
Many individuals tend to associate the battery as the main power provider for their vehicle, but in fact, it is the alternator that plays a crucial role. The alternator converts mechanical energy into electrical energy, allowing the car to charge the battery while driving. On the other hand, the starter functions differently by converting electrical energy from the vehicle into mechanical energy, facilitating the engine's initial combustion process.
Over time, both the alternator and starter may experience wear and require repair or replacement. A-Premium offers different types of starters, alternators, and battery components fitting for various models. Good parts at reasonable prices!
