Problems solved by technology

[0008] In the traditional elevator control device as mentioned above, a storage battery is used as the power storage device, but the charging and discharging performance of the storage battery will change with the change of temperature, especially at low temperature, if all the regenerative power of the elevator is charged, there will be Such a problem: There is a possibility that the voltage of the battery will rise sharply, and gas will be generated inside the battery, which will significantly deteriorate the battery

Abstract

An elevator control device having a converter, an inverter, and a controller for controlling a motor to run an elevator according to alternating current with variable voltage and frequency from the inverter, and also having: an electric storage device (10) for storing the direct current , a thermistor (32) that detects the temperature of the electrical storage device, a charge and discharge control circuit (12) that controls the charge and discharge amount according to the detected temperature and outputs a drive signal, and performs a charge and discharge control circuit (12) for the electrical storage device according to the drive signal A charging and discharging circuit (11) for charging and discharging. This device can estimate the charging and discharging capability of the electric storage device, and can protect the electric storage device and suppress its rapid deterioration.

Description

technical field [0001] The present invention relates to an elevator control device using an electric storage device, and more particularly to an elevator control device for managing the temperature of the electric storage device. Background technique [0002] A conventional elevator control device will be described with reference to the drawings. Figure 20 It is, for example, a configuration diagram of a conventional elevator control device shown in Japanese Patent Laying-Open No. 267675, 1986. [0003] exist Figure 20 Among them, 1 is a power frequency three-phase AC power supply, 2 is a converter composed of diodes, etc., 3 is a capacitor, 4 is an inverter, 5 is an electric motor such as an induction motor, 6 is a traction machine, and 7 is an elevator car. 8 is a counterweight, and 9 is a traction wire rope. In addition, 10 is a power storage device composed of a battery, 11 is a charging and discharging circuit composed of a DC / DC converter for bidirectional power con...
