CIRCUIT ARRANGEMENT FOR MONITORING THE STATE OF CHARGE OF AN ACCUMULATOR

摘要

The invention relates to a circuit arrangement for monitoring the state of charge of an accumulator, which in particular, is built into a motor vehicle, comprising a control device (1), which detects and analyses the flow of current into and out of the accumulator. The circuit arrangement is characterised in that the control device (1) may be set in a state with reduced current draw (Sleep Mode) out of which said device may be called by an activation signal (1a). Furthermore a sensor (2a, 2b, 2c, 3, 7) is provided which gives a signal on a flow of current into or out of the accumulator.
