Abstract: A device including a mechanism detecting a position of a neutral of a power supply source for an electrical energy apparatus, such as a battery charger of an electric or hybrid motor vehicle, and a mechanism connecting a capacitor for limiting leakage currents between the neutral and an electrically conducting structure in which the apparatus is placed. The device can be used to limit leakage current during recharging of an electric or hybrid traction motor vehicle.

Abstract: A compensation system for compensating for a leakage current of an electric battery charger on board a vehicle and connected to a power supply network by an electrical ground, by a neutral phase and by at least one phase other than the neutral phase, a residual current differential protection device being interposed between the battery charger and the power supply network, a leakage current flowing from the battery charger to the power supply network on the electrical ground. The compensation system includes a compensation mechanism for compensating for a leakage current and configured to emit, on the electrical ground, a compensation current of same amplitude as the leakage current and of a phase that is the opposite of phase of the leakage current.
