A method for controlling a charging apparatus of a vehicle, in particular an electric or hybrid vehicle, wherein the charging apparatus has a charging device including a protection and monitoring device. The vehicle includes a high-voltage on-board power system and an electrical energy storage apparatus connected to the high-voltage on-board power system. The method includes electrically connecting the high-voltage on-board power system to charging connections of an energy supply system by the charging apparatus. The charging connections include a neutral conductor, a protective conductor and at least one phase conductor. A protective conductor resistance is detected between the neutral conductor and the protective conductor by feeding in a test current by the protection and monitoring device. A frequency of the test current is filtered out of the compensation frequency range on a narrowband basis.
