Intelligent Battery Sensor (IBS)

Brief description:
The intelligent battery sensor (IBS) is a mechatronic component with its own microprocessor for monitoring the battery status.

The IBS is secured and connected to the negative terminal of the battery. The power supply for the IBS is fed across a separate cable. For data transmission, the IBS is connected to the DME (Digital Engine Electronics) or DDE (Digital Diesel Electronics) via the BSD (bit-serial data interface).

The vehicle with the new IBS must be placed in the idle state for at least 3 hours: Only then can the new IBS determine the battery status.
