![]() Some modern RVs are already set up to do this. With a few tweaks here and there, you can use the same alternator that charges the car battery and powers the car’s electrical system to charge your off-grid lithium battery bank (your “house” batteries). Now let’s get to the “hands-on” part of adapting your alternator to charge your lithium battery bank. How do you charge a lithium battery with an alternator? Here’s a great video explaining how car alternators work if you’re more of a visual person: The rectifier converts the alternating current (AC) generated by the alternator into direct current (DC). Since the car battery and its electrical devices need direct current (DC), every alternator has a rectifier. Thus, an alternator generates alternating current (AC), hence the name “alternator.” One is the magnet’s south pole, and the other is the north pole.Īs the engine turns the shaft (rotating the magnet), the changing magnetic field induces a current flow in a set of coils (the stator), as predicted by Faraday’s Law.īecause the magnetic field on the rotor alternates polarity (north/south), the direction of the flow of current induced in the coil also alternates many times per second. Two iron “claws” (the electromagnet) enhance this magnetic field. This electricity passing through the coil generates an electromagnetic field. The starter battery initially provides a small amount of electricity to the rotor’s coil. Thus, the alternator’s pulley (connected to the rotor shaft) also rotates. Therefore, when you turn on your car’s engine, its crankshaft begins rotating. An example of a system where a drive belt connects the crankshaft from the engine to the alternator’s pulley. This belt connects the alternator’s pulley to the engine’s crankshaft. In short, this law states that any change in the magnetic field of a coil of wire will induce a voltage in the coil.Īs previously mentioned, the alternator is connected to the engine through a drive belt. Bearings: Support the rotor shaft, allowing the rotor to rotate freely.Īn alternator works according to Faraday’s Law of Induction.Its function is to rotate the rotor as the engine runs. Pulley: Connects the engine to the rotor shaft through a drive belt.Rectifier: Converts the alternating current (AC) to direct current (DC).Voltage regulator: Limits the alternator’s voltage, ensuring it stays in the appropriate range (12V to 14V).It’s fixed to the shell of the alternator. Stator: A stationary part that houses three sets of copper wire coil windings.Rotor: A rotating magnetic element made of a wire coil enveloped around a magnet (two iron “claws”).Housing: Usually made of aluminum, given its lightweight and paramagnetic properties.An alternator’s components Alternator’s primary components.Īn alternator includes the following components: It does this through a rotor and stator system, where the rotor spins inside the stator, creating a magnetic field that induces an electrical current in the stator windings.Ī voltage regulator regulates the electrical power produced by the alternator to ensure that the battery and electrical system do not succumb to excessive voltage or current.Įssentially, the alternator is responsible for keeping the battery charged and providing electrical power to your vehicle’s electrical system while the engine runs. The alternator converts mechanical energy from the engine’s rotating crankshaft into electrical energy. What is an alternator? An alternator charges your vehicle’s battery and supplies power to its electrical system while it’s running.Ī vehicle’s alternator is an essential component of its electrical system, responsible for generating electrical power to charge the battery and power the vehicle’s electrical systems. Note to our readers: Even though any AC electrical generator can be technically called an alternator, we’re using the term alternator to refer to automotive or marine alternators. Unlike traditional lead-acid batteries, lithium batteries require a specific charging profile, so you must use a battery charger that matches up well with lithium batteries.Īdditionally, you must ensure that the charging voltage and current are within the battery manufacturer’s recommended range and monitor the battery’s temperature during charging. Regardless of the method you choose, it’s important that you exercise caution. There are three ways you can connect an alternator to your lithium battery: Yes, you can charge your lithium battery with an alternator.
