Sensor arrangement for state detection of battery and load in motor vehicle, has sensors for electric state variables of current, voltage and temperature in area of battery

摘要

The sensor arrangement (4) has sensors for electric state variables of current, voltage and temperature in the area of the battery (1). The sensor arrangement has a storage unit for storing the processes of the values of current, voltage and temperature during an engine start of the motor vehicle, and a filter unit for comparison of the measured values with stored values or with time or temperature-dependent processes of the values.
