| Zusammenfassung: | The present invention provides an elevator system which calculates an energy storage amount of an energy storage device (1) in future. When a calculated value VB' of the energy storage amount in future exceeds a preset value, energy stored in the energy storage device (11) is discharged. Furthermore at least one part of the discharged energy is consumed in an elevator cage lighting device (17) and a control device (12). In the elevator system, increasing of the energy storage capacity of the energy storage device is not required. Even when the energy storage amount is increased because of sudden increase of regenerated power, the regenerated power can be effectively used. |
