Abstract (en)

[origin: WO0208777A1] The invention relates to an electronic unit for identifying the charged state and/or the wear and tear of a motor vehicle battery. Said unit comprises elements for detecting the battery voltage and in addition, elements for detecting the speed (n*) of the internal combustion engine. The unit also has elements for evaluating the battery voltage (uBatt) according to the internal combustion engine speed during the starting operation (t2-t3), in relation to the charged state and/or the wear and tear of the motor vehicle battery.
