Can the Battery Be Charged by Idling for Twenty Minutes?

The reasons for increased fuel consumption in the Tayron GTE charging mode are as follows: Dirty Throttle: A dirty throttle can cause increased fuel consumption, so it is necessary to clean the throttle regularly, generally every 20,000 kilometers or so. Since modern vehicles use electronic throttles, it is essential to perform an idle learning procedure after cleaning the throttle; otherwise, the idle speed will become higher. Excessive Carbon Deposits in the Intake Tract: Excessive carbon deposits in the intake tract and cylinders can also lead to increased fuel consumption, so it is necessary to clean the carbon deposits in the cylinders and intake tract regularly. Generally, this should be done every 2 years or 60,000 kilometers. Aging Spark Plugs: Aging spark plugs can also cause increased fuel consumption, so they need to be replaced periodically. Ordinary spark plugs should be replaced every 30,000 kilometers or so, while platinum spark plugs should be replaced every 100,000 kilometers or so. If you notice a lack of power, they should be replaced as soon as possible.
When it comes to whether idling a car for twenty minutes can charge the battery, I think it can indeed charge the battery a little, but the effect is minimal. In the past, when I left my car idling, I thought the alternator would operate when the engine was running, and although the RPM was low, it could still output some current. However, the engine idles slowly, so the charging speed is particularly low—twenty minutes at most would only add a few volts, which is basically useless for a deeply discharged battery. Thinking about it now, if you really want to recharge the battery, it's better to drive a short distance of a few kilometers. When the engine RPM increases, the charging becomes more efficient. Prolonged idling also wastes fuel and money, so it's best to avoid it.
