Brief description

The intelligent battery sensor (IBS) is a mechatronic component with its own microcontroller for monitoring the battery condition. The IBS is secured and connected to the negative terminal of the battery. The supply voltage for the IBS is fed across a separate cable. For data transfer, the IBS is connected to the DME (Digital Engine Electronics) or DDE (Digital Diesel Electronics) via the BSD (bit-serial data interface).
