Supercapacitor moduleskazhinji vanotarisana nedambudziko remagetsi kusaenzana pakati pemasero.Iyo inonzi supercapacitor module imodule ine akati wandei supercapacitors;nekuti iyo parameter ye supercapacitor yakaoma kuenderana zvachose, iyo voltage kusaenzana kunowanzo kuitika, uye mamwe ma supercapacitor anogona kusangana ne overvoltage, iyo inokanganisa zvakanyanya kuburitsa maitiro uye hupenyu hweiyo supercapacitor, uye inototungamira mukukundikana.
Mukuita kwesupercapacitor application, voltage balancing inodiwa.Iyo iripo voltage balancing tekinoroji inonyanya kukamurwa kuita mapoka maviri: passive balancing uye inoshanda kuenzanisa.
Passive Bancing
Passive balancing ndeye kushandisa resistors uye semiconductor switch kana diode kudzikamisa voltage, uye kuita basa rekudzivirira kwe overvoltage nekushandisa yakawandisa simba reyakakwira-voltage supercapacitor.Zvakajairika zvinosanganisira parallel resistor balancing, switch resistor balancing, uye voltage regulator tube balancing.
Pano isu tinonyanya kutaura nezve yakapusa parallel resistor voltage balancing (maitiro ane simba haana kunyanya kunaka):
Req is a balancing resistor, iyo yakabatana zvakananga mukuenderana neiyo supercapacitor cell.Munguva yekuchaja yemodule, sero iri zvakare kubuda kuburikidza neReq, uye sero rine yakakwira voltage inobuda nekukurumidza, nekudaro ichitamba basa rekuenzanisa kudzivirira.Pano, maererano nenzira dzakasiyana dzekuchaja (nguva dzose yekuchaja magetsi uye inogara ichichaja, ese ari maviri anogona kushandiswa zvakazara mukuita zvinoshanda), kune zvakare misiyano mumaitiro ekusarudza Req.
Constant voltage kuchaja
Tichifunga kuti magetsi ekuchaja iU, sezvo voltage ye supercapacitor module iri munzvimbo yakatsiga inogovaniswa zvinoenderana neEPR (inenge yakavhurika dunhu mushure mekunge C yazara chaji, uye ESR idiki kwazvo), mushure mekuwedzera Req, inogona. zvinonyatso nzwisiswa sekutsiva EPR neReq, saka Req inofanirwa kusarudza zvinopikisa zvine kupikisa zvakaenzana uye zvidiki pane EPR, kuitira kuti kubatanidza kwakafanana kuite basa rinotungamira (kazhinji 0.01 ~ 0.1EPR).Iyo voltage yeiyo supercapacitor pane yakatsiga mamiriro ndeye ReqU/(nReq).
Kugara kuri kuchaja
Tichifunga kuti kuchaja ikozvino ndini, imwe neimwe supercapacitor sero uye Req inoumba yakaparadzana loop.Kana iyo voltage ye capacitor cell ichikwira, ikozvino inoyerera kuburikidza ne capacitor cell inodonha, uye ikozvino inoyerera kuburikidza neReq inowedzera.Kana iyo capacitor yazara yakazara, ikozvino ye capacitor iri 0, uye sero voltage ye capacitor iri ReqI, ndiko kuti, kana maseru emagetsi eese akatevedzana capacitors asvika ReqI, kuenzanisa kunopedzwa.Naizvozvo, kukosha kweiyo bancing resistor ndeye Req=U(rated)/I.
Active Bancing
Active balancing ndeye kuendesa simba repamusoro voltage sero kana module yese kune mamwe maseru kusvika voltage yemasero ese yadzikama.Kazhinji, kurasikirwa kunenge kwakaderera, asi kugadzirwa kuchave kwakaoma.Zvakajairika ndeye DC/DC inoshandura kuenzanisa, yakakosha super capacitor manejimendi machipisi, nezvimwe.
