Compensation system and method for a battery charger on board a vehicle

A compensation system for compensating for a leakage current of an electric battery charger within a powertrain 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, the system comprising:

• a compensation means for compensating for a leakage current flowing from the battery charger to the power supply network on the electrical ground, the compensation means 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.

A compensation method for compensating for a leakage current of an electric battery charger contained within a powertrain 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, the method comprising:

• generating on the electrical ground a compensation current of same amplitude as a leakage current flowing from the battery charger to the power supply network on the electrical ground and of a phase that is the opposite of phase of the leakage current.
