1. A power interface control device of a vehicle propulsion battery comprising:
a single closed container made of insulating material, wherein the single closed container houses:
at least four potential ports configured to carry out at least three potential differential measurements for electrical conductors associated with a power supply line interposed between a propulsion battery and a vehicle data network, the power supply line including first and second electrical conductors (BB1, BB2), wherein a first and second electrical switch (INT1, INT2) are respectively arranged on the first and second electrical conductors when in contact therewith, wherein the at least four potential ports are electrically connected upstream and downstream of each of said first and second switches (INT1, INT2) to detect any opening and dosing thereof, wherein the at least first three potential differential measurements comprise a voltage V0 measured between terminals of the propulsion battery and a power interface, a voltage V1 measured between a point upstream of a first switch (INT1) and a point downstream of a second switch (INT2) in the power supply line, and a voltage V2 measured between a point upstream of the second switch (INT2) and downstream of the first switch (INT1) in the power supply line, wherein V3 downstream from the power interface is calculated from V0, V1 and V2 voltages;
a first current sensor to carry out a first measurement of the current passing through one of the first and second electrical conductors (BB1, BB2) of said power interface;
actuation means to control opening and closing of the first and second electrical switches of said power interface;
processing means configured for:
acquiring said differential measurements and said current measurement,
controlling said actuation means; and
interface means to allow an operational interfacing between said processing means and the vehicle data network;
wherein the single closed container further comprises connection means to allow a mechanical coupling between the container and both the first and second electrical conductors (BB1, BB2), and an electrical coupling between one of the at least four potential ports in the container and one of the first and second electrical conductors of the power supply line via a first connector (CONN1) to provide power directly to the device, wherein a remainder of the at least four ports are in electrical communication with a third connector (CONN3) configured for connection via the interface means to the vehicle data network, wherein a second connector (CONN2) is configured to provide connection between the actuation means and at least first and second electrical switches (INT1, INT2) to detect and control any opening and closing of at least the first and second electrical switches (INT1, INT2).
