摘要
The invention relates to a device for controlling the electrical power supply of a circuit for a vehicle, said vehicle comprising: an electrical battery (2); an electrical energy storage element (C1), one terminal of which is connected to the first terminal (VBAT) of the battery and the other terminal of which is connected to an electrical earth; a first circuit (5), capable of consuming electricity coming from the electrical battery (2), and having first and second terminals respectively connected to the first and second terminals (-VBAT, VBAT) of the battery (2); and electrical supply management means (Q1) configured to allow or prevent the passage of electrical current between said electrical energy storage element (C1) and said first circuit (5). Said control device comprises detection means (41) configured to detect a drop in voltage of the battery (2) below a threshold value, and command means (42) configured, in the event of detection of a drop in voltage of the battery below said threshold value, to command said electrical supply management means (Q1) in order to prevent the passage of electrical current between the electrical energy storage element (C1) and said first circuit (5).
