  Battery sensor (as of 1.6.06) 74    M  o   d  e   l   2   1   1   /   2   1   9 Overview of Battery and On-Board Electrical System - Passenger Car Model Series 2006 b Battery sensor (B95) (as of 1.6.06) Function/location As of 1.6.06, the battery sensor (B95) together with the rear SAM control unit with fuse and relay module (N10/2) manages the on-board electrical system, thus replacing the previous battery control unit (N82).Installed directly at the negative terminal of the battery, the battery sensor (B95) measures the voltage, current and temperature at the battery (G1) and from these it evaluates the state of the battery.Over a LIN interface the battery sensor (B95) forwards the measured values, which are used to manage the on-board electrical system, to the rear SAM control unit with fuse and relay module (N10/2).The following measures can be initiated to stabilize the on-board electrical system:ãShutoff of consumer groups 1 and 2 (now not until 10.5 V and both simultaneously (previously emergency stage 3), no display in instrument cluster (A1))ãShutoff of the electrical accessory socketãIdle speed increase on shutoff of consumer group 2 P54.15-2983-00 B95 Battery sensor G1 Battery  P54.15-2984-00  – This printout will not be recorded by the update service. Status: 04 / 2007 –  Battery sensor (as of 1.6.06)    M  o   d  e   l   2   1   1   /   2   1   9 75 Overview of Battery and On-Board Electrical System - Passenger Car Model Series 2006 b Function/design The battery sensor (B95) is integrated in the nega-tive clip of the ground line at the battery (G1) itself. The measurement electronics (circuit board) in the battery sensor (B95) is mounted directly on a shunt (defined resistance). It has an extremely large measuring range (from mA values up to over 1000 A) at a high resolution. This means that it is possible to monitor quiescent current.If a quiescent current greater than 75 mA is measured 75 min after the vehicle is locked, the battery sensor (B95) wakes the rear SAM control unit with fuse and relay module (N10/2) and a data record is created.This data record stores information about the magnitude of the quiescent current (min./max. value, the battery voltage (start/end of the event), duration (min) and kilometer reading of the quies-cent current event in a non-volatile memory (EEPROM), i.e. the data are preserved even if a voltage reset is carried out.A total of 5 data records with information about the quiescent current event can be stored in the rear SAM control unit with fuse and relay module (N10/2) and read out using DAS (accessed via Control units , Body , On-board electrical system , Actual values ).In addition, these data records also indicate the active/inactive status for consumers such as the low beam, stationary heater etc. This makes fault diagnosis easier.
