<p>According to a method for determining the characteristics of an insulation fault between an electric circuit including an accumulator battery (2) in a motor vehicle and the vehicle ground (3), the battery (2) comprising first and second terminals (22) for supplying the circuit, measuring means comprising a first resistive branch (16) are connected between a first terminal 21 of the battery (2) and the ground (3), and a first measurement is taken representative of the current in the first resistive branch (16), a second measurement similar to the first measurement is taken by connecting the measuring means between the second terminal (22) of the battery (2) and the ground (3), and a position of an insulation fault inside the battery (2) is deduced from the relationship between the first and second measurements . A device taking such measurements.</p> |
