An energy monitoring system for discharging energy in an energy transfer device of a vehicle, including an isolation monitoring unit, a capacitor unit, a voltage terminal unit and a control unit. The voltage terminal unit is connectable to an energy storage system and transfers energy from the energy storage system to a vehicle subsystem. The isolation monitoring unit includes a first isolation resistor element and switch element. The resistor element is connectable to the voltage terminal unit via the switch element. The capacitor unit is connected to the voltage terminal unit and filters electromagnetic interference by storing energy during energy transfer to the subsystem. The control unit closes the first isolation switch element in case of a disconnection of the energy transfer to form a discharge circuit connecting the isolation monitoring unit and the capacitor unit. The discharge circuit discharges energy stored in the capacitor unit.
