Can a Car Charge the Battery at Idle Speed?

[SebastianLee]

Yes. Here is the relevant information about the battery: How the battery is charged: The engine directly drives the generator via a belt, so once the engine is started, the electricity generated by the alternator is rectified and voltage-regulated before being directly supplied to the car battery for charging. Introduction to the battery: It refers to a battery that can be reused after being discharged and recharged. Types include lead-acid batteries, nickel-iron batteries, and nickel-cadmium batteries. In a lead-acid battery, the positive electrode is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution. During discharge (use), the positive and negative electrodes react with sulfuric acid to form lead sulfate. When the concentration of the sulfuric acid solution drops to a certain level, the battery must be recharged. Using an external power source for charging can restore the electrodes and electrolyte to their original state, allowing the battery to be reused after charging.
