Nhasi, kana zvigadzirwa zvekuchengetedza simba zvichikura, supercapacitors (farad-level capacitors) ine simba rekuchengetedza simba senge Ultra-yakakwirira simba, yekupedzisira-yakakwira ikozvino, yekupedzisira-yakafara yekushanda, yekupedzisira-yakanyanya kuchengetedzwa, uye yekupedzisira-yakareba hupenyu hunoshandiswa. chete, uye pamwe chete nezvimwe zvigadzirwa zvekuchengetedza simba.Kushandiswa kweComposite kunova kwakajairika.Kune vashandisi, zvakakosha zvikuru kusarudza yakakodzera supercapacitor.
Ndeapi mamiriro achashanda kune supercapacitors?
1) Instant simba repamusoro, senge UAV ejection mudziyo;
2)Nguva pfupi-yezvino kuwanikwa, senge tochi dzemapurisa;
3)Kakawanda kukwirisa (kudzika) uye deceleration (kumusoro) mamiriro, akadai braking simba kudzoreredza midziyo;
4)Diesel mota dzinotangwa mukutonhora kwakanyanya kana mumamiriro ekutadza kwebhatiri;
5)Backup magetsi ekugadzira magetsi emhepo, solar thermal power generation, nuclear power uye mamwe materminals ekugadzira magetsi;
6) Mhando dzese dzehupenyu hurefu, kuvimbika kwepamusoro, kuchengetedza-isina, yakakwirira-simba density backup magetsi emagetsi;
Kana iwe uchida mudziyo une hukuru hwesimba hunhu uye humwe huwandu hwesimba kutyaira midziyo yemagetsi, yenguva refu yekuchengetedza-isina, uye kugona kushanda munzvimbo yakakura tembiricha, kunyanya kana izvo zvekuchengetedza zvinodiwa zvakanyanya kuomarara paminus 30 kusvika 40 madhigirii, inguva yekusarudza yakakodzera supercapacitor.
Ruzivo rwaunofanirwa kuziva usati wasarudza supercapacitor
Saka rudzii rwe supercapacitor runogona kusangana nezvido zvako?Ndeapi akakosha ma paramita e supercapacitors?Maparamita ayo makuru ndeye voltage (V), capacitance (F) uye yakayerwa ikozvino (A).
Izvo zvinodikanwa zvesimba, nguva yekuburitsa uye system voltage shanduko mune chaiyo mashandisirwo eiyo supercapacitors inoita basa rekuita mukusarudzwa kwemuenzaniso.Mumashoko akareruka, marudzi maviri eparameter anofanira kutsanangurwa: 1) Operating voltage range;2) Simba rinobuda kukosha kana kuti kuburitsa kwazvino kunotora nguva yakareba sei.
Maitiro ekuverenga iyo inodiwa supercapacitor capacitance
(1) Nguva dzose ikozvino, kureva, kana ikozvino uye nguva mu supercapacitor kushanda mamiriro anogara aripo: C = It / ( Vwork -Vmin)
Somuenzaniso: kushanda kutanga voltage Vwork = 5V;kushanda-cut-off voltage Vmin = 4.2V;nguva yekushanda t=10s;kushanda magetsi I=100mA=0.1A.Kugona kunodiwa ndiko: C =0.1*10/(5 -4.2)= 1.25F
Muchiitiko ichi, unogona kusarudza chigadzirwa chine capacitance ye 5.5V1.5F.
(2) Simba renguva dzose, ndiko kuti, kana simba rekubuda kwesimba risingaperi: C * ΔU2 / 2 = PT
Semuyenzaniso, inoenderera ichiburitsa pasi pe200KW simba kwemasekonzi gumi, iyo inoshanda voltage renji i450V-750V, inodiwa capacitance capacitance: C=220kw10/(7502-4502)=11F
Naizvozvo, capacitor (simba rekuchengetedza sisitimu) ine capacitance ye11F pamusoro pe750V inogona kusangana nezvinodiwa izvi.
Kana iyo yakaverengerwa capacitance isiri mukati mechikamu chechikamu chimwe chete, akawanda supercapacitors anogona kubatanidzwa munhevedzano uye akaenzana kugadzira module kuti isangane nezvinodiwa nevatengi.
Multi-capacitor parallel calculation formula: C=C1+C2+C3+…+Cn
Multi-capacitor akatevedzana calculation formula: 1/C=1/C1+1/C2+…+1/Cn
Mazano ezvimwe zvigadzirwa
(1) High-voltage series zvigadzirwa zvine zvakanakira muzviitiko zvakawanda
Ndezvipi zvakanakira zve-high-voltage (2.85V uye 3.0V) zvigadzirwa?
Indekisi yehupenyu (1,000,000 cycle life) inoramba isingachinji, uye iyo chaiyo simba uye chaiyo simba rinowedzera pasi pevhoriyamu imwechete.
Pasi pemamiriro ekugara nesimba uye simba, kuderedza nhamba yezvikamu uye uremu hwehurongwa hwese hunogona kukwidziridza dhizaini yehurongwa.
(2) Kuita zvinodikanwa chaizvo
Panyaya yezvinodikanwa zvekushandisa, iyo yakapfava voltage value reference haina zvazvinoreva.Semuenzaniso, tembiricha yakakwira pamusoro pe65 ℃, 2.5V yakatevedzana zvigadzirwa isarudzo yakanaka.Izvo zvinofanirwa kucherechedzwa kuti, senge ese e electrochemical zvikamu, ambient tembiricha ichakanganisa zvakanyanya hupenyu hwema supercapacitor, uye hupenyu huchapetwa kaviri kune yega 10 ℃ kuderera kwepamusoro tembiricha nharaunda.
Chimiro uye electrode zvinhu zve supercapacitors hazvina kutsanangurwa mupepa rino, nokuti zvisizvo zvisingaverengeki zvigadziro zvine zvishoma zvakakosha pakusarudzwa kweiyo supercapacitors.Zvinofanira kucherechedzwa kuti hapana chigadziriso chesimba rekuchengetedza simba, uye kushandiswa kwakasanganiswa kwemidziyo yakawanda yekuchengetedza simba kwave sarudzo yakanyanya kunaka.Saizvozvo, ma-supercapacitor anoshandisa mamwe masimba ekuchengetedza simba kuti aenderere mberi zvawo zvakanakira, uye ari kuitawo mukurumbira.
Kuti utenge zvigadzirwa zvemagetsi, unofanirwa kutsvaga mugadziri akavimbika kutanga.JYH HSU(JEC) Electronics Ltd (kana kuti Dongguan Zhixu Electronic Co., Ltd.) ine huwandu hwakazara hwemhando dzevaristor uye capacitor dzine mhando yakavimbiswa.JEC yakapfuura ISO9001: 2015 quality management system certification.Kugamuchirwa kuti utitane nesu kune matambudziko ehunyanzvi kana kushandira pamwe kwebhizinesi.Webhusaiti yedu yepamutemo: www.jeccapacitor.com
