Momwe Ma Supercapacitors Amakwanitsira Kulinganiza kwa Voltage

Supercapacitor modulesnthawi zambiri amakumana ndi vuto la kusalinganika kwamagetsi pakati pa maselo.Zomwe zimatchedwa supercapacitor module ndi module yomwe ili ndi ma supercapacitors angapo;chifukwa magawo a supercapacitor ndi ovuta kuti agwirizane kwathunthu, kusalinganika kwa voteji kumakhala kosavuta kuchitika, ndipo ma supercapacitor ena amatha kukumana ndi kuchulukirachulukira, komwe kumakhudza kwambiri mawonekedwe ndi moyo wa supercapacitor, ndipo ngakhale kumabweretsa kulephera.

Pogwiritsa ntchito supercapacitor, kusinthanitsa kwamagetsi ndikofunikira.Tekinoloje yomwe ilipo yamagetsi yama voliyumu imagawika m'magulu awiri: kusanja mokhazikika komanso kusanja mwachangu.

Passive Balancing

Kusanjikiza kosalekeza ndiko kugwiritsa ntchito ma resistor ndi ma semiconductor switch kapena ma diode kuti azitha kuwongolera mphamvu yamagetsi, komanso kutenga gawo lachitetezo chochulukirapo pogwiritsa ntchito mphamvu zochulukirapo za supercapacitor yamphamvu kwambiri.Zodziwika bwino zimaphatikizapo kusanja kofananira, kusintha kopingasa, ndi kusanja machubu owongolera ma voltage.
Apa tikulankhula makamaka za kusanja kwamagetsi kofananirako kosavuta (makhalidwe amphamvu siabwino kwambiri):

Req ndi chopinga chofananira, chomwe chimalumikizidwa mwachindunji ndi cell ya supercapacitor.Panthawi yolipiritsa gawoli, seloyo imatulukanso kudzera mu Req, ndipo selo lomwe lili ndi mphamvu zambiri limatuluka mofulumira, motero limasewera gawo lotetezera chitetezo.Apa, molingana ndi njira zolipirira zosiyanasiyana (kuthamangitsa voteji nthawi zonse komanso kuyitanitsa komweko, zonse zomwe zingagwiritsidwe ntchito momveka bwino pamapulogalamu ogwiritsira ntchito), palinso kusiyana pamiyeso yosankha Req.

Kuthamanga kwamagetsi kosalekeza
Kungoganiza kuti voteji yolipiritsa ndi U, popeza voteji ya gawo la supercapacitor pamalo okhazikika amagawika molingana ndi EPR (pafupifupi dera lotseguka pambuyo pa C litayimitsidwa, ndipo ESR ndi yaying'ono kwambiri), pambuyo powonjezera Req, imatha zimveka ngati kusintha EPR ndi Req, kotero Req ayenera kusankha resistors ofanana kukana ndi ang'onoang'ono kuposa EPR, kotero kuti kulumikizana kofanana kutha kutenga gawo lotsogola (nthawi zambiri 0.01 ~ 0.1EPR).Mphamvu yamagetsi ya supercapacitor pamalo okhazikika ndi ReqU/(nReq).

Kuchapira nthawi zonse
Pongoganiza kuti pakali pano ndi ine, selo iliyonse ya supercapacitor ndi Req imapanga loop yosiyana.Mphamvu ya cell capacitor ikakwera, yomwe ikuyenda mu cell capacitor imatsika, ndipo yomwe ikuyenda kudzera mu Req imawonjezeka.Pamene capacitor ili ndi mlandu, mphamvu ya capacitor ndi 0, ndipo mphamvu yamagetsi ya capacitor ndi ReqI, ndiko kuti, pamene magetsi amtundu wa ma capacitors onse afika ku ReqI, kugwirizanitsa kumatsirizidwa.Chifukwa chake, mtengo wa zopinga zofananira ndi Req=U(rated)/I.

Kusamalitsa Mwachangu

Kusamutsa kwamphamvu ndikusamutsa mphamvu yamagetsi apamwamba kwambiri kapena gawo lonse kupita ku ma cell ena mpaka mphamvu ya ma cell onse ikhala yokwanira.Kawirikawiri, kutayika kumakhala kochepa, koma mapangidwe ake adzakhala ovuta kwambiri.Zodziwika bwino ndi DC/DC converter balancing, zida zapadera zowongolera ma super capacitor, ndi zina zambiri.
