Description And Operation: Description
The Intelligent Battery Sensor (IBS) (1):
- Is packaged on the battery negative pole.
- Is a microcontroller based device used to measure battery current, voltage, and temperature.
- Sends calculated battery health state to the Body Control Module (BCM) via LIN bus.
The signals from the IBS will be used in the energy management strategy
The IBS
- Does not have a direct diagnostic interface.
- Must be diagnosed through its LIN master, the BCM
- Any IBS faults will be present in the BCM
