Abstract:
1. A device for connection of a battery to an electric or hybrid motor vehicle, comprising at least one input adapted to be connected to a first terminal of the battery and at least one output adapted to be connected to a first terminal of an electrical circuit of the vehicle, wherein the device also comprises: a device for measuring the voltage between the first terminal of the battery and a reference potential; a control unit adapted to receive the voltage values measured by the voltage-measuring device adapted to determine an insulation resistance between the first terminal of the battery and the reference potential, and adapted for connecting or keeping connected the first terminal of the battery and the first terminal of the electrical circuit if said insulation resistance is greater than a determined threshold; and an electrical circuit disconnection device fitted in series between the input and the output of the connection device, the electrical circuit disconnection device being controlled by the control unit; wherein the disconnection device comprises a pyrotechnic igniter connected to control terminals, the electrical opening of the disconnection device being controlled by an electrical control signal applied to said control terminals.
