Can a Car Charge While Running but Not Moving? A car can charge while running but not moving, but the charging current depends on the engine speed. Within certain limits, the higher the engine speed, the greater the charging current. The method for charging a car is: 1. Connect the positive terminal of the charger to the positive terminal of the car battery, and the negative terminal of the charger to the negative terminal of the battery; 2. Press the charging button to start charging. Precautions for charging a car include: 1. If the battery voltage is 10% lower than the rated voltage, it may lead to battery depletion; 2. Avoid water entering the battery during charging; 3. Charge the battery directly without removing it to prevent data loss.
I've been driving for over 30 years and have experienced all sorts of battery issues. The car can charge when idling after starting because the engine operation drives the alternator to recharge the battery. I often do this in winter myself to prevent battery drain and freezing, especially with older models. But be careful not to idle the engine for too long - it wastes gasoline and emits more exhaust, which is bad for the environment. Once I did this in the garage for over 40 minutes and the exhaust pipe started smoking, nearly causing an accident. If you just need a temporary charge (like when the battery is slightly weak), idling the engine for about 10 minutes is sufficient. However, I recommend regularly driving the car for better results - this charges the battery more fully and lasts longer, while also keeping the engine healthier with less wear. Remember to check the charging indicator light on the dashboard - it's fine if it stays on normally.
