Abstract:Inordertorealize theidentificationof the electric bicyclecharging loadontheuser side,the load current ontheuser sideiscollectedinreal time through theInternetof Things(IoT)circuit breaker.The disturbance timepointof thecurentcurve isquickly identified.Theinfluenceof theperiodic loadis filteredout, andthe basic characteristics of the disturbance current curve are extractedto form theabsolutevalue increment curve.Accordingto theformationcriteriaofthe initial transient pulse peak,time limitwidthofthecharging current curve and thepulse peak,time limit widthand symmetry ofthe current waveform at the beginning of steady-state charging,combined with the change of power increment and harmonic increment beforeand after charging,the chargingloadoftheelectricbicycleisidentifiedtoalarmortripthecircuitbreaker,soastoensurethatthe chargingloadof theelectric bicycleisforbiddeninthechargingareaofthenon-electricbicycle.Experimentsshow thatthe proposed method is simpleand effctive,and can be implemented locallythrough theIoTcircuit breaker.
