Can the car battery charge when the engine is running but the car is not moving?

[McJoseph]

Can the car battery charge when the engine is running but the car is not moving? The car battery is charged by the engine. After the car is started, the engine begins to work, and the power is transmitted to the generator through the engine belt. As long as the engine is running, the car battery will remain in working condition. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine is stopped or idling at low speed, it supplies power to the car's electrical equipment; 3. When the generator output is insufficient, it can assist in supplying power to the electrical equipment; 4. It mitigates voltage surges in the electrical system and protects the car's electronic devices; 5. It can store excess electricity generated by the generator.
