A backup circuit for supplying electricity to an electronic overspeed governor in connection with a malfunction of a main electricity supply is disclosed. The backup circuit includes an energy storage. The backup circuit is configured to disconnect the supply of electricity from the energy storage to the electronic overspeed governor with a delay when the malfunction of the main electricity supply is detected, and when the malfunction of the main electricity supply continues for a predetermined amount of time, restarting the supply of electricity from the energy storage to the electronic overspeed governor.
