Problems solved by technology

At this time, after the normal power supply is restored, the battery power supply is charged, and the rescue operation is performed after the charging is completed, so there is a problem that the rescue operation to the nearest floor cannot be performed when the normal power supply abnormality occurs, and passengers are trapped. The state of the elevator

Embodiment 1

[0022] figure 1 It is a block diagram showing the configuration of the power supply system according to Embodiment 1 of the present invention. Such as figure 1 As shown, the power supply system 10 of this embodiment includes a general power supply 100 , an electrical storage device 300 , a charging and discharging control device 400 , a power supply control device 500 , and an integrated control ECU (electronic control unit: electronic control unit) 600 .

[0023] The general power supply 100 is, for example, a commercial power supply, and also includes a generator using an engine as a power source, and the like. The load device 200 includes various loads driven based on power supply.

[0024] Power storage device 300 stores surplus power from general power supply 100 and regenerative electric power generated in load device 200 , and supplies the stored power to load device 200 as needed. The power storage device 300 has a configuration in which N power storage element bloc...

Embodiment 2

[0061] Next, Example 2 of the present invention will be described. In Embodiment 1 above, the power supply capacity of the power storage device is increased by resetting the operable voltage of the power storage device when the normal power supply is stopped. On the other hand, in Embodiment 2 of the present invention, when the normal power supply is stopped, the outputtable electric power or the electric power amount of the power storage device is compared with the electric power or electric power amount required for the minimum operation of the load device, and when When the electric power or the amount of electric power required for the minimum operation of the load device is greater than the outputtable electric power or electric power of the electric storage device, the power supply amount of the electric storage device is increased by resetting the operable voltage of the electric storage device.

[0062] Hereinafter, power supply control processing of the power supply c...

Abstract

The invention provides a power supply system in which power supply capacity of an electric power accumulator can be increased temporarily when normal power supply is stopped, a power supply control method of the power supply system, a power supply control program of the system, and a computer readable recording medium having power supply control program of the system recorded thereon. Upon receiving normal power supply stop information from an integral control ECU, a control section lowers an operatable voltage determined as an output voltage for ending discharge of the electric power accumulator and delivers the lowered operatable voltage from a communicating section to the integral control ECU. Based on the lowered operatable voltage, the integral control ECU controls a charge / discharge controller to increase power supply capacity of the electric power accumulator.

Description

technical field [0001] The present invention relates to a power supply system including a power storage device that supplies power when a general power supply such as a commercial power supply fails, a power supply control method for the power supply system, a power supply control program for the power supply system, and a computer-readable recording medium for recording the power supply control program for the power supply system . Background technique [0002] In recent years, power storage devices have attracted attention and been utilized as backup power sources for commercial power sources. The backup power supply is a mechanism that is charged when the commercial power supply is working normally, and continuously supplies power to the equipment instead of the commercial power supply when the commercial power supply is abnormal. As such an example, UPS (Uninterruptible Power Supply: uninterruptible power supply) can be mentioned. When the commercial power supply fails...
