  • Switching status check with circuit parts of an insulation monitor
    Patent number: 9817073
    Abstract: A battery management system for a high-voltage battery that has a switching device with controllable switching elements for establishing and disconnecting an electrical connection between the poles of the high-voltage battery and the connection points for a consumer network, and a device for insulation monitoring. The poles and connection points are each switched to a reference potential for insulation measurement via a voltage divider. The battery management system may have a device for checking the switching status of the controllable switching elements by means of measuring devices for determining the electrical voltage. The measuring devices are arranged so that they measure the voltage between the output of the respective voltage divider and the reference potential. The device for checking the switching status of the controllable switching elements has a device for comparing the measured voltage values of the two measuring devices.
