Abstract: A method for determining the state of an electrical line connecting a cell of a battery to a monitoring unit of said battery, said electrical line including a first electrical branch connecting a positive terminal of said cell to a first input terminal of said monitoring unit and a second electrical branch connecting a negative terminal of said cell to a second input terminal of said monitoring unit, said method includes: calculating a value of the line resistance of said electrical line; and determining the state of said electrical line as a function of said calculated line resistance value.

Abstract: A device for charging a battery, or a battery of an electric traction automotive vehicle, based on a three-phase or single-phase power supply network, including a filtering stage including a capacitive assembly and configured to be connected to the power supply network. The device includes a mechanism to monitor capacitive assembly and to detect a deviation in value of the capacitance of at least one capacitor of the capacitive assembly on the basis of voltages and currents measured across the input terminals of the filtering stage.
