Abstract: 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.

Abstract: The invention relates to a method and a measuring arrangement for identifying insulation faults and line defects occurring in a modularly set-up voltage source during the production process as soon as possible. Simultaneously to the assembly progress, electrical parameters, such as the leakage resistance and the leakage capacitance, are determined. Furthermore, it is ensured by means of monitoring a connection in the mostly automated production process that the measuring arrangement is properly connected to the voltage source.

Abstract: The invention relates to a method for controlling electric power provided at a charging station for an electric vehicle, the charging station being fed by a plant for generating renewable energy, said plant being installed close enough to the charging station that a physical and meteorological parameter value acting at the location of the plant and determining the power generated by the plant is approximately equal to the value of the parameter at the location of the charging station. The physical meteorological parameter is measured at the location of the charging station and the electric power provided by the charging station is controlled by changing a charging current as a function of the measured physical and meteorological parameter. Furthermore, the invention relates to a charging station for an electric vehicle that implements the aforementioned method for controlling the provided electric power.
