Battery Current Sensor: Description and Operation
GF54.10-P-2100CW Battery Sensor Component Description
Component Identification
Location
The battery sensor is located at the negative terminal of the on-board electrical system battery (G1).
The battery sensor and on-board electrical system battery on vehicles with a gasoline engine are located in the engine compartment, on vehicles with a
diesel engine in the trunk.
Task
The battery sensor provides the following on-board electrical system battery (G1) values to the rear SAM control unit with fuse and relay module
(N10/2) over the on-board electrical system LIN:
^
Voltage
^
Interior temperature
Function
The battery sensor is connected in series with the negative terminal of the on-board electrical system battery and the ground point. It records the voltage
of the on-board electrical system battery and the on-board electrical system's power consumption. These measurements are used by the battery sensor to
calculate the internal resistance of the on-board electrical system battery. A temperature sensor integrated into the battery sensor measures the
temperature at the negative terminal. This is then used to calculate the inside temperature of the on-board electrical system battery.
