Hyundai Kona: ISG (Idle Stop & Go) System / AGM Battery Description and operation
[AGM Battery for ISG System]
AGM battery is used for especially heavy load on the vehicle network depending
on equipment and requirements. AGM stands for Absorbent Glass Material Battery;
that is absorbent glass fibre fleece. AGM batteries are fitted in models with
electrical loads/consumers which have a high energy demand.
The constantly increasing energy demand of modern vehicle electrical systems
calls for ever more powerful battery solutions.
The power consumption is considerable even when the vehicle is parked.
The somewhat higher price compared with a battery of similar size is fully balanced
by the following benefits :
| – |
Significantly longer service life
|
| – |
Increased starting reliability at low temperatures
|
| – |
100 % freedom from maintenance
|
| – |
Low risk in event of an accident (reduced risk to the environment)
|
| Check the battery condition |
The battery condition cannot be determined solely on the basis of the battery
charge state. If there is a suspicion of a damaged battery, check the battery
condition whit battery tester and investigate the cause by means of the test
module. With a low battery charge state, recharge the battery.
| Recharging the AGM battery |
The battery may be charged using the battery chargers at a constant charge voltage
of 14.8V.
If possible, the battery temperature during charging should be between 20°C
(68°F) and 30°C (86°F).
Only chargers with voltage clamping (IU or WU curve) may be used or chargers
with IUoU curve which have a trickle.
|
IU or WU charging technique
Optimized charging voltage for IU or WU : 14.7V (at 20°C - 30°C (68°F
- 86°F)) about 24 hours
Min. charging voltage at 20°C (68°F) : 14.4V
Max. charging voltage at 20°C (68°F) : 14.8V
10% of capacity is recommended as charging current (e.g. 60Ah : 10 =
6,0A charging current).
|
| • |
Do not charge the AGM battery with>15.2V. No quick-charging
routines.
|
|
| • |
If the battery is charged directly at the battery terminals
on vehicles with battery sensor, misinterpretations of battery
condition and under certain circumstances also unwanted Check
Control messages or fault memory entire can occur.
After recharging finished, let the battery stand for over 10
hours with normal temperature for battery stabilization.

Inspection
1.
Check installation status of BBVPS and Vacuum hose or damage of vacuum
hose.
2.
Connect GDS to DLC (Data Link Cable).
