Automotive Electrical System or Automobile Electrical System: Engineering Hulk describes in detail how the electrical system of an automobile car, vehicle, bike works
There are mainly two types of charging methods in Automobiles namely constant voltage charging and constant current charging: Constant Voltage Charging: In this method, the charging voltage is kept constant throughout the charging process. In this method, the charging current is high at first, when the battery is discharged, and gradually drops off as the…

Definition: Batteries use sponge lead and lead peroxide to convert chemical energy into electrical energy. This type of battery is called the lead-acid battery. Lead-acid batteries are often used in power stations and substations because of their high cell voltage and low cost. Construction of lead-acid batteries The different parts of lead-acid batteries are shown…

All alternators work on the principle of electromagnetic induction. According to this act, a conductor, magnetic field, and mechanical energy are required to generate electricity The main parts of an alternator are, apparently, a stator and a rotor. But, unlike other machines, in most alternators, the field exciter rotates and the armature coil becomes stationary….
Definition of Dynamo An electrical machine that converts mechanical energy into direct current electricity. Dynamo construction It consists of three main parts, namely the magnetic field system, the armature and the commutator, and the brush gear. Other parts of a DC generator are a magnetic frame and yoke, pole core and pole shoes, field or…
Construction of Bendix drive The figure shows the Bendix drive to start the motor. It is attached to the starter motor armature shaft. The drive head is fitted to the end of the armature shaft. The pinion gear, which has internal threads, is mounted in a threaded sleeve, just like a bolt nut. The sleeve…
Starter Motor: A starter motor converts the electrical energy stored in the battery into mechanical energy to crank the engine for starting. A simple electric motor includes a horseshoe-shaped soft-iron yoke with field windings wound around each of the two pole pieces. The armature winding rotates between the pole-pieces with its ends attached to each…
