DEVICE FOR DETECTING THE DISCONNECTION OF A BATTERY FROM AN ELECTRIC POWER SUPPLY NETWORK, BY ANALYSIS OF CURRENT STABILITY CONSIDERED BY AN IMPOSED OPERATING VARIATION OF AN ELECTRICAL DEVICE
DEVICE FOR DETECTING THE DISCONNECTION OF A BATTERY FROM AN ELECTRIC POWER SUPPLY NETWORK, BY ANALYSIS OF CURRENT STABILITY CONSIDERED BY AN IMPOSED OPERATING VARIATION OF AN ELECTRICAL DEVICE
The device (D) has an analysis unit (MA) analyzing current measured close to a terminal of a battery (BA) and delivering a current signal when the current is stable. A control unit (MC) commands operation variation of an electric body formed of electricity consuming bodies (O1-O3) and a power supply source (AL) e.g. alternator, during reception of an alert signal. The control unit generates an alarm signal representative of disconnection of the battery of a power supply network (RA) in case of continuity of reception of the signal after initiation of the variation.
