Car Charging System Diagram Pdf

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.

Car charging system diagram pdf.

The battery has pairs of lead plates immersed in a mixture of sulphuric acid and distilled water. Half of the plates are connected to each terminal. A car uses quite a lot of electricity to work the ignition and other electrical equipment. A battery which provides current to initiate the magnetic field required to operate the ac.

If the charging system stopped working the battery s charge would soon be depleted leaving the car with a dead battery. A charging system voltage drop check can help you locate the source of an under charge or over charge condition due to problems in the wiring or connections between the battery and alternator. 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. This energy is needed to operate the loads in the vehicle s electrical system.

Start the engine and let it idle. The charging system converts mechanical energy into electrical energy when the engine is running. Troubleshooting for unusual charging system voltage drops. The charging system requires little maintenance.

Diagnosis of charging system problems is typically straightforward. Problems may be electrical or mechanical. Figure 8 2 contains the following. Ac charging system components the automotive charging system.

When the charging system s output is greater than that needed by the vehicle it sends current into the battery to maintain the battery s state of charge.
