When the control means 1 determines that the charging capacity of the battery 11 has reached a predetermined value or less during the service of the car 6, the car call and the hall corresponding to the driving direction of the car 6 are performed. In addition to responding to the call, the car 6 is moved to a predetermined position and charged after these services are completed. The invalidation means for invalidating the hall call until the battery 11 is charged to a predetermined capacity or more is:
For example, the control unit 11 includes the control unit 11. Further, the calculating means 20 calculates the battery 1 based on the charging / discharging current of the battery 11.
