Can the Battery Be Charged While the Car Is Idling?

[DiLincoln]

Yes, the battery can be charged while the car is idling. When the battery charging indicator light on the dashboard is off, it indicates that the car is charging the battery. Precautions for battery charging include: 1. Connect the charger directly to the battery to avoid removing it, as this may result in data loss; 2. If the battery voltage is 10% lower than the rated voltage, it may lead to battery depletion; 3. Avoid exposing the battery to water during charging. The functions of the battery are: 1. Providing power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. Supplying power to the car's electrical equipment when the engine is off or idling at low speed; 3. Assisting in powering electrical devices when the generator's output is insufficient; 4. Mitigating voltage surges in the electrical system to protect the car's electronic devices; 5. Storing excess electricity generated by the alternator.
