Abstract
Emergency current supply equipment for lift installations with electric motor drives has the task of bridging over temporary drops or interruptions in main voltage and of supplying, in the event of failure of the mains supply during a lift travel, all components of the lift installation needed for an evacuation travel with energy until such time as the lift car has reached the level of a story. The energy storage unit used for that purpose comprises as the storage medium exclusively capacitors in the form of super capacitors or a combination of super capacitors and electrochemically acting batteries.
