Hyundai Veloster: Battery Sensor
Description and Operation
Description
Vehicles have many control units that use more electricity. These units
control their own system based on information from diverse sensors. It is important
to have a stable power supply as there diverse sensors giving a variety of information.
Battery sensor (A) is mounted on battery (-) terminal. It transmits battery
voltage, current, temperature information to ECM. ECM controls generating voltage
by duty cycle based on these signals.

When battery sensor signal fault occurs, inspect the vehicle parasitic
draw in advance after inspecting the sensor because the sensor will
behave abnormally when the parasitic draw is more than 100mA. (Refer
to vehicle parasitic current inspection)

It takes a few hours for a new battery sensor to detect the battery
state correctly.
Perform the following process after replacing the battery sensor.
1. |
Ignition switch ON/OFF.
|
2. |
Park the vehicle about 4 hours.
|
3. |
After 4 hours later, check that the SOC (State of charge)
of battery is displayed on GDS properly.
|
|
For the vehicle equipped with a battery sensor, be careful not
to damage the battery sensor when the battery is replaced or recharged.
•
|
When replacing the battery, it should be same one (type,
capacity and brand) that is originally installed on your vehicle.
If a battery of a different type is replaced, the battery sensor
may recognize the battery to be abnormal.

|
When installing the ground cable on the negative post
of battery, tighten the clamp with specified torque of 4.0~6.0N.m
(0.4~0.6kgf.m, 3.0~4.4lb-ft). An excessive tightening torque
can damage the PCB internal circuit and the battery terminal.
|
•
|
When recharging the battery, ground the negative terminal
of the booster battery to the vehicle body.
