  "textContent": "The present disclosure relates to a ground fault monitoring system for an energy storage system, an energy storage system comprising such a ground fault monitoring system, a vehicle comprising such an energy storage system, a method for ground fault monitoring for an energy storage system and a computer program element for such a ground fault monitoring system. [0002] The ground fault monitoring system comprises an isolation monitoring unit, a first main switch, a second main switch and a control unit. The isolation monitoring unit is arrangeable between the energy storage system and a ground element. The first main switch and the second main switch are arrangeable between the energy storage system and an external energy supply system. The isolation monitoring unit comprises a first switchable resistor branch, a second switchable resistor branch and a third switchable resistor branch. The control unit is configured to close the first main switch and the second main switch during charging of the energy storage system for connecting the energy storage system to the external energy supply system. The control unit is further configured to disconnect the first switchable resistor branch from the energy storage system and connect the second switchable resistor branch and the third switchable resistor branch to the energy storage system for monitoring a current leakage to the ground element during charging of the energy storage system.",
