Device and method for charging a battery from a three-phase network, having a degraded charging mode. This device for charging a battery, in particular a battery of an electric traction automotive vehicle, from a three-phase supply network, comprises a first filtering stage intended to be connected to the three-phase network, a voltage step-down stage (3) connected to the filtering stage, a voltage step-up stage (4) intended to be connected to the battery and coupled to the voltage step-down stage via an inductive component, and a regulating unit (CPU) adapted for imposing cyclic switching ratios on the voltage step-down stage (3) and on the voltage step-up stage (4). It comprises means (CPU) for comparing the operating temperature of the regulating unit with a threshold value and means for controlling the charging on the basis of two phases of the three-phase network when the operating temperature of the regulating unit exceeds said threshold value. |
