  "textContent": "A circuit arrangement discharges at least one energy store charged to a high voltage in a motor vehicle. The circuit arrangement includes a discharge circuit which is connected in parallel with the energy store and contains an auxiliary microcontroller for actuating the discharge circuit. The auxiliary microcontroller can be operated with a low voltage of 3-5 volts and contains a first voltage supply circuit for supplying the auxiliary microcontroller with the low voltage of 3-5 volts, which first voltage supply circuit is fed from a buffer capacitor with a voltage of 10-15 volts. The circuit arrangement further contains a main microcontroller, which is configured to actuate the auxiliary microcontroller so that the latter actuates the discharge circuit.",
