ABSTRACT:
A circuit configuration for monitoring the state of charge of an accumulator battery, which is installed in particular in a motor vehicle, has a control unit that records and evaluates the flow of current out of or into the accumulator battery. The control unit is able to be shifted into a state with low current consumption (sleep mode), out of which it may be brought again by an activation signal. Moreover, a sensor is provided that emits a signal in response to a flow of current out of or into the accumulator battery.
