CHG-7

< SYSTEM DESCRIPTION >

[TYPE 1]

The battery current sensor is installed to the battery negative cable.
The sensor measures the charging/discharging current of the bat-
tery.

BATTERY TEMPERATURE SENSOR

Battery temperature sensor is integrated in battery current sensor.
The sensor measures temperature around the battery.
The electrical resistance of the thermistor decreases as temperature
increases.

SYSTEM DIAGRAM

SYSTEM DESCRIPTION

• Battery current sensor (With battery temperature sensor) measures the charging/discharging current of the

battery and the temperature around the battery.

• IPDM E/R judges battery condition according to the charging/discharging current of the battery and the tem-

perature around the battery.

• IPDM E/R calculates the target power generation voltage according to the battery condition and sends the

calculated value as alternator voltage request signal to ECM via CAN communication.

• ECM transmits alternator voltage request signal to alternator via LIN communication.
• Control module inside alternator controls the power generation voltage based on the received alternator volt-

age request signal.

• Alternator includes a self-diagnosis function and transmits the diagnosis result to ECM via LIN communica-

tion when detecting any malfunction.

• Charge warning lamp turns ON when any of the following symptom occurs while ignition switch is ON:
- Excessive voltage is produced.
- No voltage is produced.
- High voltage is detected from battery positive terminal.
- The communication between alternator and ECM is not available.

NOTE:
Charge warning lamp turns OFF while stop/start system is activated.
