First, the control device 19 determines whether or not the charging state of the power storage device 7 is an insufficient charging state based on the detection result of the charging state detection device 9 (step S101). When the control device 19 determines that the state of charge of the power storage device 7 is not an undercharged state in step S101, the control device 19 displaces the solar battery power changeover switch 12 to the normal position, and further changes the motor power changeover switch 14 to the normal state.

  Further, when the charging state detection device 9 detects that the charging state of the power storage device 7 is a fully charged state, the control device 19 sets the position of the motor power switch 14 to the discharging position. When the state of charge is a fully charged state, the electric power generated in the motor 31 can be switched from the power storage device 7 to the AC power supply device 11 and sent. Thereby, when the state of charge of the power storage device 7 is a fully charged state, the power sent to the power storage device 7 can be reduced, and the charge state of the power storage device 7 can be prevented from being overcharged. it can. As a result, deterioration of the power storage device 7 can be suppressed. Moreover, since the electric power which generate | occur | produces in the motor 31 is sent to the alternating current power supply device 11, surplus electric power can be utilized effectively.

  Moreover, since the control device 19 sets the position of the open / close switch 101 to the ON position when the charge state detection device 9 detects that the charge state of the power storage device 7 is an undercharged state, the charge state of the power storage device 7 Can be sent to the power storage device 7 when the battery is undercharged. Thereby, even if it is a case where the charge condition of the electrical storage apparatus 7 is an insufficient charge state, the cage | basket | car 1 can be raised / lowered.

  In addition, according to the control method for an elevator apparatus according to Embodiment 1 of the present invention, when the charging state detection device 9 detects that the charging state of the power storage device 7 is a fully charged state, the control device 19 Since the position of the solar battery power changeover switch 12 is set to the discharge position, the power of the solar battery 8 can be switched from the power storage device 7 to the AC power supply device 11 when the power storage device 7 is fully charged. it can. Thereby, when the state of charge of the power storage device 7 is a fully charged state, the power sent to the power storage device 7 can be reduced, and the charge state of the power storage device 7 can be prevented from being overcharged. it can. As a result, deterioration of the power storage device 7 can be suppressed. Moreover, since the electric power of the solar cell 8 is sent to the alternating current power supply device 11, surplus electric power can be used effectively.

Next, the operation of the elevator apparatus will be described. FIG. 6 is a flowchart showing the operation of the elevator apparatus of FIG. First, the control device 19 determines whether or not the car 1 is stopped between floors based on the information on the rotational position ω _s of the motor 31 sent from the encoder device 4 (step S201). If the control device 19 determines in step S201 that the car 1 is not stopped between the floors, step S201 is repeated.

  On the other hand, when the control device 19 determines in step S201 that the car 1 is stopped between the floors, the control device 19 displaces the solar battery power changeover switch 12 to the normal position, and moves the motor power changeover switch 14 to the normal position.
