Abstract

A method for controlling a battery charger circuit of a vehicle. The method includes injecting a first current pulse between at least one line and a protective earth connection of the battery charger circuit. The method also includes measuring at least one line voltage value of at least one node of the battery charger circuit. The method also includes identifying a noise value by performing one or more operations on the battery charger circuit. The method also includes determining a protective earth connection impedance based on the at least one line voltage value and the noise value.
