Car battery charging system diagram.

The regulated dc out voltage is given to battery. If the power came from an ordinary battery it would soon run down so a car has a rechargeable battery and a charging system to keep it topped up. Usually the first sign that your charging system is in trouble is a battery alt or charge warning light illuminating on your instrument panel while driving. A car uses quite a lot of electricity to work the ignition and other electrical equipment.

A summer circuits edition on all things outdoors good but what of all the battery powered circuits that remains indoors. Once the fine weather starts the family car tends to remain increasingly in the garage which is as beneficial to the owner his her bank account and the air that we breathe as it helps to an extent to reduce co2 emissions. Half of the plates are connected to each terminal. Test your charging and electrical system.

The battery has pairs of lead plates immersed in a mixture of sulphuric acid and distilled water. It means that the alternator voltage output is below 12 volts or over its limit or has stopped charging the battery and your car is running on battery power. I hope this helps people avoid wasting money on parts. The circuit diagram of the lead acid battery charger is given below.

The purpose of the charging system is to maintain the charge in the vehicle s battery and to provide the main source of electrical energy while the engine is running. There is also a trickle charge mode circuitry which will help to reduce the current when the battery is fully charged. A lead acid battery has certain defined characteristics than make it easy to evaluate the health of the charging system without fancy test gear.
