Abstract
Official abstract text for this publication.
An elevator system provided in an existing apartment building, includes a motor that is a drive source for a lifting mechanism of an elevator car, a power storage device configured to store power supplied to the motor, and a charger configured to charge the power storage device with power supplied from a power grid. A traveling motor, an in-vehicle power storage device, and an in-vehicle charger of a used vehicle are diverted to the motor, the power storage device and the charger. The power storage device is used as a normal power supply of the elevator system. The motor is driven by power supplied from not the power grid but the power storage device.
First claim
Opening claim text (preview).
What is claimed is: 1 . An elevator system provided in an existing apartment building, comprising: a motor that is a drive source for a lifting mechanism of an elevator car; a power storage device configured to store power supplied to the motor; and a charger configured to charge the power storage device with power supplied from a power grid, wherein a traveling motor, an in-vehicle power storage device, and an in-vehicle charger of a used vehicle are diverted to the motor, the power storage device and the charger of the elevator system, the in-vehicle power storage device is used as a power supply of the elevator system in case of an emergency of a power failure, and the motor is driven by power supplied from not the power grid but the in-vehicle power storage device. 2 . The elevator system according to claim 1 , further comprising: an air conditioner configured to air-condition inside the elevator car, wherein an in-vehicle air conditioner of a used vehicle is diverted to the air conditioner. 3 . The elevator system according to claim 1 , wherein the motor is driven by power supplied from the in-vehicle power storage device whether it is in a normal or emergency situation. 4 . The elevator system according to claim 1 , further comprising: a drive circuit configured to drive the motor, wherein an in-vehicle drive circuit, of the used vehicle, configured to drive the traveling motor is diverted to the drive circuit. 5 . The elevator system according to claim 1 , further comprising: a supply unit configured to supply power of the power storage device to an electric load of the apartment building. 6 . The elevator system according to claim 1 , wherein the power storage device is charged with the charger in a predetermined unused time zone of the elevator.
