BackgroundArt

Inrecentyears,apoweraccumulatorhasdrawnwideattentionandbeenusedasbackuppowersource.Abackuppowersourceischangedwhenacommercialpowersourceoperatednormally,andcontinuessupplypowertoequipmentinplaceofthecommercialpowersourcewhencommercialpowersourcehasadefect.ExamplesofsuchabackuppowersourceincludeaUPS（UninterruptivePowerSource）.Byinstantaneouslyswitchingthecommercialpowersourcetoanoutputofthebackuppowersourceincaseofpoweroutage,acomputerorastorageunitinuse,aswellasnetworkequipmentsuchasaserverarepreventedfrombeingstopped.

Suchabackuppowersourcecombinedwiththepoweraccumulatoriscontrolledtomaintainresidualcapacityrepresentingthestateofchargeatahighlevel.Inthissystem,generallybecausesurpluspowerischargedinpoweraccumulatorefficientlybyapowergenerationactionofanelectricmotor,charge|dischargecontrolisperformedsothattheSOCdoesnotexceed100%.Inordertosupplypowertotheelectricmotorwhennecessary,charge|dischargecontrolisperformedsothattheSOCdoesnotdecreaseto0（zero）.Specially,normallyinpoweraccumulator,thecontrolisperformedsothattheSOCfluctuateswithinarangeof20%to80%.

Withregardtoelevators,ontheotherhand,ahybridelevatorthathasacageandacounterweighttoinhibitunnecessarypowerconsumptionduringtheoperationofhybridelevatorhasbeendeveloped.Suchahybridelevatorutilizesthepowerofitsbatteryatthetimeofpoweroutage,sothatincaseofpoweroutageorotherabnormalstateduringofoperationofthehybridelevator,thepowerfordrivingtheelevatorissuppliedfromapowersourcetocarrytheelevatortothenearestfloororanyfloorandsafelyretrievethepassagefromthestage.

Thefollowingmethodisproposedasamethodforcontrollinganautomaticlandingdeviceoftheelevator.PatentDocument1,forexample,disclosesamethodfordetectingtheoutputvoltage,outputcurrent,andatemperatureofabatterypowersourcetoperformarescueoperationinresponsetothepowersupplycapacityofthebatterypowersource.

Moreover,thehybridelevatorhastoalwayssecureenergyamountforcarryingtheelevatortoanecessaryfloorincaseofemergencyduringthenormaloperationofcommercialpowersource,andthereonalargepoweraccumulatorwithalargecapacityrequired.

InthemethoddisclosedinPatentDocument1,theoutputvoltageandthevoltagesetvaluearecomparedwitheachotherbyadischargetimeanddischargestateofthebatteryisdetectedbythemagnituderelationtherebetweentocontroltheoperationoftheelevator.Therefore,whenthepowersupplycapacityofthebatterypowersourceislow,thepowersupplycapacitywillbelost,therebystoppingthepowersupplyfromthebattery.Inthiscase,becausechargingofthebatterypowersourceisstartedaftertheinterruptiblepowersourcereturns,andtherescueoperationisconducteduponcompletionofthecharging,theelevatorcannotbecarriedtothenearestfloortoperformrescueoperationinthecaseofanabnormalsituationoftheinterruptiblepowersource.Asaresult,thepassengersremaintrappedintheelevator.

Moreover,whentheinterruptiblepowersourceisstoppedduetodisasterlikeasinthehybridelevator,itisnecessaryforthebackuppowersourcetoensuretheminimumpowersupplycapacityforenablingminimumoperation.Consequently,becauseamarginbecomesnecessaryinthecapacityofthebackuppowersource,alargepoweraccumulatorisnecessary.

Inaddition,theminimumvoltageusedforcalculatingthepowersupplycapacityhasamargin,inviewofthelifeproperty.Therefore,thevalueoftheactualpowersupplycapacityissmallerthanthethatoftheprimarypowersupplycapacityofthepoweraccumulator.
