How long does it take the car to start charging the battery?

If the vehicle is not malfunctioning, the battery will start charging after the engine starts, and the power consumed at the start can be filled in almost 3-5 minutes. The engine charging the battery is actually not much related to time, mainly related to the operation of the engine. When the engine is normally idling, the charging indicator is turned off, so the generator begins to generate electricity. The higher the engine speed, the greater the power generation will be. After the generator's power generation meets the electricity of the car's electrical appliances, the rest will be charged.

The engine is normally idling, the charging indicator is extinguished, and the generator begins to generate electricity. The higher the engine speed, the greater the power generation. The remaining part of the generator's power generation can only charge the battery after meeting the electricity of the vehicle's appliances. So charging the battery isn't a matter of time, it's a matter of how the engine works.

When the engine starts, the generator replaces the battery to supply the electric equipment on the car and charge the battery. After the engine starts, about two or three minutes as the generator continues to operate, the voltage emitted will slowly be higher than the battery voltage. At this time, the generator will slowly replace the battery to power the electric equipment on the car and charge the battery.

Like our mobile phones, charging takes time. If the vehicle runs for a long period of three or five minutes, then the generator can not fill the power lost when the vehicle is started. In the long run, the battery has been in a state of loss. It will lead to the shortening of the service life of the battery and often the failure to start the vehicle. If it is a vehicle that often runs short distances, it is recommended to run away from time to time. Or often use a dedicated battery charger for charging.

In fact, the charging indicator on the vehicle does not indicate whether the battery is charging or not, nor does it indicate what speed the engine is charging at. When the alternator is heavily loaded, the charging indicator will also be extinguished. The battery is not charging but discharging. It is also important to note that if the charging indicator does not go out at high speed, it indicates that the alternator, regulator, line or transmission belt has failed.
