Vehicle Charging- and Starting systems

How do a vehicle charging and starting system work?



The battery stores electrical energy and the starter convert that energy that turns the engine to start. The alternator produces an electric current to replace what the starter used during start-up and to support electrical loads when the engine is running. An ignition module, including the ignition coil produces the high voltage for the ignition system. This creates a spark at the spark plugs and ignites the air/fuel mixture in the engine. A belt transmits power from the vehicle’s engine to an alternator’s pulley, along with other accessories.

Factors influencing the system

  • Frequent switching and engine on/off will cause more wear on the charging and starter system than a single long-distance trip.
  • Weather and driving conditions also impact the longevity of a battery in conjunction with the vehicle’s age, kilometers done, and the extensive use of in-vehicle infotainment and communication systems.

Symptoms indicating possible problems with the Charging & Starting system includes:

  • System warning lights illuminate - e.g. “Check Engine” or “Battery
  • Headlights and interior lights dim
  • Infotainment and other electronic accessories fail to operate
