An automotive vehicle may include a battery charger that receives electrical energy, via an electrical connection including a ground wire, from an electrical source remote from the vehicle, and outputs the electrical energy to at least one electrical load. The vehicle may also include at least one controller that commands a change in the electrical energy output by the battery charger. The battery charger, in response to the command, may control a rate of change in the electrical energy output such that a coupling current to the ground wire resulting from the change in the electrical energy output by the battery charger has a magnitude less than a predetermined threshold.
