Battery
It converts the chemical energy to the
electrical energy and supplies power to the
corresponding electric units when starting
the engine.Alternator
The alternator charges the battery and
supplies power to each electric unit by
converting the mechanical energy to the
electrical energy.
1. SYSTEM DESCRIPTION
1) Overview
The charge system is designed to supply electrical energy to the vehicle while driving, and supplies a
constant direct current voltage by converting mechanical rotational movement to electrical energy.
The voltage regulator on the back of the alternator controls the generated voltage in all rotating ranges
and adjusts the system voltage according to the electric load and ambient temperature change.

3) Charging
The alternator uses a new regulator which has three diodes. It consists of the delta stator, rectifier bridge,
slip ring and brush.
Charging time according to vehicle conditions and environment
Specification: Charging a fully depleted high-
capacity battery takes twice or more as long as
charging a fully depleted battery for small vehicles.
Temperature: The lower the temperature is, the
longer the time taken to charge the battery. When
connecting the battery charger to the cold battery,
the amount of current the battery can accept
initially is very small. As the battery gets warmer, it
can accept more current.
Charging capacity: Charging a battery with a low-capacity charger takes longer time than charging with
a high-capacity charger.
Charging status: Charging a fully depleted battery takes twice or more as long as charging a half-
depleted battery. Since the electrolyte in a fully depleted battery consists of nearly pure water and
conductor, only a very small amount of current can be accepted by the battery initially. The charging
current increases as the amount of acids in the electrolyte is increased by the charging current.

(9) PTC heater control
a. Overview
The supplementary electrical heater is installed in DI engine equipped vehicle as a basic equipment. The
PTC system is operated according to two temperature values measured at the coolant temperature
sensor and HFM sensor. This device is mounted in the heater air outlet and increase the temperature of
air to the passenger compartment. Because PTC system is heated by electrical power, high capacity
alternator is required. PTC does not operate during engine cranking, while the battery voltage is lower
than 11 V or during preheating process of glow plugs.

1) Drive Belt
Overview
There are two types of belt system; EPS (Electric Power Steering) and HPS (Hydraulic Power Steering).
In the vehicle with ESP, instead of power steering pulley, the idle pulley is installed on the engine.
The belt system is a single belt drive system which uses single V-belt with 6 grooves. This design
provides the long life span and minimizes the belt slip and noise.
