WIPO Patent Application WO/2013/038098
Kind Code:
A3
Abstract:
Device (1) for charging a battery (2), in particular a battery of an electric traction automotive vehicle, on the basis of a three-phase or single-phase power supply network (3), comprising a filtering stage (5) comprising a capacitive assembly (5b) and intended to be connected to the power supply network (3). The device (1) comprises means (8) for monitoring the capacitive assembly (5b) able to detect a deviation in the value of the capacitance of at least one capacitor (C) of the capacitive assembly (5b) on the basis of the voltages and currents measured across the input terminals (Bls, B2, B3) of the filtering stage (5).
