Amamojula we-Supercapacitorbavame ukubhekana nenkinga yokungalingani kwamandla kagesi phakathi kwamaseli.Okubizwa ngokuthi i-supercapacitor module iyimodyuli equkethe ama-supercapacitor amaningana;ngenxa yokuthi imingcele ye-supercapacitor inzima ukungaguquguquki ngokuphelele, ukungalingani kwamandla kagesi kujwayele ukwenzeka, futhi amanye ama-supercapacitor angase abhekane nokugcwala ngokweqile, okuthinta kakhulu izici zokukhishwa nokuphila kwe-supercapacitor, futhi kuholele ngisho nokwehluleka.
Enqubweni yokufaka isicelo se-supercapacitor, ukulinganisa kwamandla kagesi kuyadingeka.Ubuchwepheshe obukhona bokulinganisa amandla kagesi buhlukaniswe ikakhulukazi izigaba ezimbili: ukulinganisa okwenziwayo kanye nokulinganisa okusebenzayo.
I-Passive Bancing
I-Passive balancing iwukusebenzisa izinto eziphikisayo kanye namaswishi e-semiconductor noma ama-diode ukuze kulinganiswe amandla kagesi, kanye nokudlala indima yokuvikela i-overvoltage ngokusebenzisa amandla eqile e-high-voltage supercapacitor.Ezivamile zihlanganisa ukulinganisa okuhambisanayo kwe-resistor, ukulinganisa kwe-switch resistor, nokulinganisa kweshubhu yesilawuli se-voltage.
Lapha sikhuluma kakhulu ngokulinganisa okulula kwe-resistor voltage balancing (izici eziguqukayo azilungile kakhulu):
I-Req iyisixhasi sokulinganisa, esixhunywe ngokuqondile ngokuhambisana neseli ye-supercapacitor.Phakathi nenqubo yokushaja ye-module, iseli liphinde likhiphe nge-Req, futhi iseli elinogesi ophezulu likhipha ngokushesha, ngaleyo ndlela lidlala indima yokuvikela ukulinganisa.Lapha, ngokwezindlela zokushaja ezihlukene (ukushaja kwe-voltage njalo kanye nokushaja kwamanje okungashintshi, zombili ezingasetshenziswa ngokuphelele ezinhlelweni zokusebenza), kukhona futhi umehluko ezimisweni zokukhetha i-Req.
Ukushaja ugesi njalo
Uma sicabanga ukuthi i-voltage yokushaja ingu-U, njengoba i-voltage yemojula ye-supercapacitor esimweni esiqinile isatshalaliswa ngokuya nge-EPR (isifunda cishe esivulekile ngemuva kokuthi i-C ishajwe ngokugcwele, futhi i-ESR incane kakhulu), ngemuva kokwengeza i-Req, ingakwazi. empeleni kuqondwe njengokuthatha indawo ye-EPR nge-Req, ngakho-ke i-Req kufanele ikhethe ukumelana nokumelana okulinganayo nezincane kune-EPR, ukuze ukuxhumana okuhambisanayo kudlale indima eholayo (ngokuvamile i-0.01~0.1EPR).I-voltage ye-supercapacitor esimweni sokuzinza i-ReqU/(nReq).
Ukushaja kwamanje njalo
Ngokucabanga ukuthi ukushaja kwamanje I, iseli ngalinye le-supercapacitor kanye ne-Req bakha iluphu ehlukile.Lapho i-voltage yeseli ye-capacitor ikhuphuka, yamanje egeleza ngeseli ye-capacitor iyehla, futhi yamanje egeleza nge-Req iyanda.Uma i-capacitor ishajwe ngokugcwele, i-current ye-capacitor ingu-0, futhi i-voltage yeseli ye-capacitor i-ReqI, okungukuthi, lapho ama-voltages amaseli awo wonke ama-capacitor ochungechunge efika ku-ReqI, ukulinganisa kuqediwe.Ngakho-ke, inani le-bancing resistor lithi Req=U(rated)/I.
Ukulinganisa Okusebenzayo
Ukulinganisa okusebenzayo ukudlulisa amandla eseli ye-voltage ephezulu noma yonke imojula kwamanye amaseli kuze kube yilapho i-voltage yawo wonke amaseli isilingana.Ngokuvamile, ukulahlekelwa kuncane, kodwa ukuklama kuzoba nzima kakhulu.Okujwayelekile ukulinganisa kwe-DC/DC converter, ama-chips akhethekile okuphatha i-super capacitor, njll.
