Ngaba ii-Supercapacitors zifezekisa njani ukulinganisa kwamandla ombane

Iimodyuli ze-Supercapacitorbahlala bejongana nengxaki yokungalingani kwamandla phakathi kweeseli.Imodyuli ebizwa ngokuba yi-supercapacitor yimodyuli equlethe ii-supercapacitors ezininzi;ngenxa yokuba iiparamitha ze-supercapacitor zinzima ukuba zingaguquguquki ngokupheleleyo, ukungalingani kwamandla ombane kuthanda ukwenzeka, kwaye ezinye ii-supercapacitors zinokufumana ukugqithiswa kwamandla, okuchaphazela kakhulu iimpawu zemveliso kunye nobomi be-supercapacitor, kwaye zikhokelela ekungaphumeleli.

Kwinkqubo yokusetyenziswa kwe-supercapacitor, ukulinganisa kwamandla ombane kuyimfuneko.Itekhnoloji ekhoyo yokulinganisa amandla ombane yahlulahlulwe yaziindidi ezimbini: i-passive balancing kunye ne-active balancing.

I-Pasisive Balancing

I-Passive balancing kukusebenzisa i-resistors kunye ne-semiconductor switch okanye i-diode ukulinganisa amandla ombane, kunye nokudlala indima yokukhusela i-overvoltage ngokusebenzisa amandla angaphezulu kwe-high-voltage supercapacitor.Ezona zixhaphakileyo ziquka ukulinganisa ukuchasana okuhambelanayo, ukutshintshiselana kwe-resistor balancing, kunye ne-voltage regulator tube balancing.
Apha sithetha ikakhulu ngeyona ndlela ilula yokulinganisa i-resistor voltage balancing (iimpawu eziguqukayo azilunganga kakhulu):

 

I-Supercapacitor passive balancing

 

I-Req yi-resistor yokulinganisa, edityaniswe ngokuthe ngqo ngokuhambelana neseli ye-supercapacitor.Ngexesha lokutshaja kwemodyuli, iseli iphinda ikhuphe ngeReq, kwaye iseli ene-voltage ephezulu ikhupha ngokukhawuleza, ngaloo ndlela idlala indima yokukhusela ukulinganisa.Apha, ngokweendlela ezahlukeneyo zokutshaja (ukutshaja kombane rhoqo kunye nokutshaja okuthe rhoqo kwangoku, zombini ezinokuthi zisetyenziswe ngokupheleleyo kwizicelo ezisebenzayo), kukho umahluko kwiikhrayitheriya zokukhetha i-Req.

Ukutshaja umbane rhoqo
Ukucinga ukuba i-voltage yokutshaja i-U, ekubeni i-voltage yemodyuli ye-supercapacitor kwisimo esizinzileyo isasazwa ngokwe-EPR (malunga nesekethe evulekileyo emva kokuba i-C ihlawulwe ngokupheleleyo, kwaye i-ESR incinci kakhulu), emva kokongeza i-Req, iyakwazi. eneneni iqondwe njengokutshintsha i-EPR nge-Req, ngoko ke i-Req kufuneka ikhethe izichasi ezinokuxhathisa ngokulinganayo kwaye zincinci kune-EPR, ukuze unxibelelwano oluhambelanayo ludlale indima ephambili (ngokubanzi i-0.01 ~ 0.1EPR).Umbane we-supercapacitor kwindawo ezinzileyo yi-ReqU/(nReq).

Ukutshaja rhoqo ngoku
Ukucinga ukuba umjelo wokutshaja ndim, iseli nganye ye-supercapacitor kunye ne-Req zenza i-loop eyahlukileyo.Xa i-voltage ye-capacitor cell iphakama, i-current flowing through the capacitor cell drops, kwaye i-current flowing through Req iyanda.Xa i-capacitor ihlawuliswa ngokupheleleyo, i-current ye-capacitor yi-0, kwaye i-voltage yeseli ye-capacitor yi-ReqI, oko kukuthi, xa i-voltages yeseli yazo zonke ii-series capacitors ifikelela kwi-ReqI, ukulinganisa kugqityiwe.Ngoko ke, ixabiso le-bancing resistor yi-Req=U(rated)/I.

 

Ulungelelaniso olusebenzayo


Ukulinganisa okusebenzayo kukudlulisa amandla eeseli zombane eziphezulu okanye imodyuli iyonke kwezinye iiseli de amandla ombane azo zonke iiseli alingane.Ngokuqhelekileyo, ilahleko iphantsi, kodwa ukuyila kuya kuba nzima ngakumbi.Ezona ziqhelekileyo ziyi-DC/DC converter balancing, iichips ezikhethekileyo zolawulo lwe-super capacitor, njl.
