Supercapacitor moduleshangata ba tobana le bothata ba ho se leka-lekane ha motlakase pakeng tsa lisele.Seo ho thoeng ke supercapacitor module ke module e nang le li-supercapacitor tse 'maloa;hobane litekanyetso tsa supercapacitor li thata ho lumellana ka ho feletseng, ho se leka-lekane ha motlakase ho tloaelehile ho etsahala, 'me li-supercapacitor tse ling li ka' na tsa e-ba le overvoltage, tse amang ka ho teba litšobotsi tsa tlhahiso le bophelo ba supercapacitor, esita le ho lebisa ho hlōleha.
Ts'ebetsong ea ts'ebeliso ea supercapacitor, ho leka-lekanya ha motlakase hoa hlokahala.Theknoloji e teng ea ho leka-lekanya motlakase e arotsoe haholo ka mekhahlelo e 'meli: ho leka-lekanya ho sa sebetseng le ho leka-lekanya ho sebetsang.
Ho leka-lekanya ho sa Feleng
Passive balancing ke ho sebelisa li-resistors le semiconductor switch kapa diode ho leka-lekanya motlakase, le ho bapala karolo ea ts'ireletso ea overvoltage ka ho sebelisa matla a feteletseng a super-voltage supercapacitor.Tse tloaelehileng li kenyelletsa ho leka-lekanya ho hanyetsana, ho lekanngoa ha li-switch resistor, le voltage regulator tube balancing.
Mona re bua haholo ka "parallel resistor voltage balancing" (litšobotsi tse matla ha li ntle haholo):
Req ke mohanyetsi oa ho leka-lekanya, o hokahaneng ka kotloloho ho bapa le sele ea supercapacitor.Nakong ea ts'ebetso ea ho tjhaja mochine, sele e boetse e tsoa ka Req, 'me sele e nang le matla a phahameng a motlakase e tsoa ka potlako, kahoo e bapala karolo ea ho leka-lekanya tšireletso.Mona, ho latela mekhoa e fapaneng ea ho tjhaja (charging voltage kamehla le tjhaja e sa khaotseng ea hajoale, tseo ka bobeli li ka sebelisoang ka botlalo lits'ebetsong tse sebetsang), ho boetse ho na le phapang lipakeng tsa mekhoa ea ho khetha Req.
Ho tjhaja voltage kamehla
Ho nka hore motlakase oa ho tjhaja ke U, kaha motlakase oa mojule oa supercapacitor o boemong bo tsitsitseng o abuoa ho latela EPR (hoo e batlang e le potoloho e bulehileng ka mor'a hore C e lefelloe ka botlalo, 'me ESR e nyenyane haholo), ka mor'a ho eketsa Req, e ka khona. ha e le hantle e utloisisoa e le ho nkela EPR sebaka ka Req, kahoo Req e tlameha ho khetha lihanyetsi tse nang le khanyetso e lekanang le tse nyane ho feta EPR, e le hore khokahano e tšoanang e ka bapala karolo ea mantlha (ka kakaretso 0.01 ~ 0.1EPR).Matla a matla a supercapacitor ha a tsitsitse ke ReqU/(nReq).
Ho tjhaja kamehla
Ho nka hore hona joale ho tjhaja ke I, sele e 'ngoe le e' ngoe ea supercapacitor le Req e theha loop e arohaneng.Ha voltage ea sele ea capacitor e phahama, hona joale e phallang ka har'a sele ea capacitor e theoha, 'me hona joale e phallang ka Req e eketseha.Ha capacitor e qosoa ka ho feletseng, hona joale ea capacitor ke 0, 'me selefouno ea capacitor ke ReqI, ke hore, ha li-voltages tsa lisele tsa li-capacitor tsohle li fihla ReqI, ho leka-lekanya ho phethoa.Ka hona, boleng ba mohanyetsi oa ho leka-lekanya ke Req=U(rated)/I.
Ho leka-lekanya ka mafolofolo
Active balancing ke ho fetisetsa matla a sele e phahameng ea voltage kapa module kaofela ho lisele tse ling ho fihlela motlakase oa lisele tsohle o leka-lekane.Ka kakaretso, tahlehelo e batla e le tlaase, empa moralo o tla ba o rarahaneng haholoanyane.Tse tloaelehileng ke li-converter tsa DC / DC, li-chips tse khethehileng tsa tsamaiso ea super capacitor, joalo-joalo.
