How exactly does the battery charge while driving? Learn in simple language

You may think that the battery in your car or bike is only used to start the vehicle. But once the car is started, a small power plant is running inside the car to operate the horn, headlights, AC and screen, and also to keep the battery constantly charged. Here’s the interesting process of exactly how the battery charges while driving:

1. Main Hero: Stator Coil or Alternator

The main task of charging the battery is done by the ‘Stator Coil’ in a bike and the ‘Alternator’ in a car. It is the car’s own ‘mini power house’. When we start the engine, the rotation of the engine causes this stator coil or alternator to rotate. According to science’s law of electromagnetic induction, this rotation produces a large amount of electricity.

2. Conversion of current: R.R. unit

The electricity produced by the engine’s rotation is ‘alternating current’ (AC), while your battery can only store ‘direct current’ (DC). Also, when the engine speeds up, this current builds up to very high levels, sometimes up to 30-40 volts, which can burn out the battery.

• Here R.R. The unit comes to work. It converts this AC current into DC and regulates the voltage to a constant 12 to 14 volts, which is required to safely charge the battery.

3. Battery charging and supply

RR This regulated DC current from the unit is sent directly to the battery. The longer the vehicle is driven or the engine is running, the more current is stored in the battery and the battery is fully charged. Once the car is started, the headlights and horn are powered directly from this coil/alternator, reducing the load on the battery.

‘This‘ Be sure to remember

Disadvantages of Short Trips: If you only use the car for 2-3 minute intervals, there is no time to recharge the electricity used during self-driving. As a result, the battery deteriorates quickly.

Additional Modifications: Adding fancy fog lights or a big horn to the outside of the car puts stress on the stator coil and the battery begins to discharge instead of charging.

As the car runs, its battery stays charged. So if you want to increase the life of the battery, it is very important to drive the car continuously for 10-15 km at least once a week.
