Masiku ano, pamene zinthu zosungiramo mphamvu zikuyenda bwino, ma supercapacitor (farad-level capacitors) okhala ndi mphamvu zosungirako mphamvu monga ultra-high mphamvu, ultra-high current, ultra-wide working range, ultra-high chitetezo, ndi moyo wautali wautali amagwiritsidwa ntchito. yekha, komanso kuphatikiza ndi zinthu zina zosungira mphamvu.Kugwiritsa ntchito kompositi kumakhala kofala.Kwa ogwiritsa ntchito, ndikofunikira kwambiri kusankha supercapacitor yoyenera.
Ndi zochitika ziti zomwe ma supercapacitors angagwiritse ntchito?
1) Instant mkulu mphamvu, monga UAV ejection chipangizo;
2) Kupezeka kwakanthawi kochepa, monga tochi za apolisi;
3) Kuthamanga pafupipafupi (kutsika) ndi kutsika (m'mwamba), monga zida zobwezeretsa mphamvu zamagetsi;
4) Magalimoto a dizilo amayambika nyengo yozizira kwambiri kapena ngati batire ikulephera;
5) Kusungirako magetsi opangira mphamvu zamphepo, kupangira magetsi a solar, magetsi a nyukiliya ndi malo ena opangira magetsi;
6) Mitundu yonse ya moyo wautali, wodalirika kwambiri, wopanda kukonza, mphamvu zosunga zobwezeretsera zamphamvu kwambiri;
Ngati mukufuna chipangizo chokhala ndi mphamvu zambiri komanso mphamvu zina zoyendetsera zida zamagetsi, kukonza kwanthawi yayitali, komanso kuthekera kogwira ntchito mosiyanasiyana kutentha, makamaka ngati zofunikira zachitetezo ndizokhazikika paminus 30 mpaka Madigiri 40, ndi nthawi yoti musankhe supercapacitor yoyenera.
Zomwe muyenera kudziwa musanasankhe supercapacitor
Ndiye ndi mtundu wanji wa supercapacitor womwe ungakwaniritse zosowa zanu?Kodi magawo ofunikira a supercapacitor ndi ati?Magawo ake akuluakulu ndi magetsi (V), capacitance (F) ndi ovotera panopa (A).
Zofunikira zamagetsi, nthawi yotulutsa ndi kusintha kwamagetsi pamakina ogwiritsira ntchito ma supercapacitors amatenga gawo lalikulu pakusankha kwachitsanzo.Mwachidule, mitundu iwiri ya magawo iyenera kufotokozedwa: 1) Mtundu wamagetsi ogwiritsira ntchito;2) Mphamvu yotulutsa mphamvu kapena kuchuluka kwa zomwe zikuchitika panopa.
Momwe mungawerengere capacitance yofunikira ya supercapacitor
(1) Pakali pano, ndiye kuti, pamene panopa ndi nthawi ya supercapacitor yogwira ntchito nthawi zonse: C=It/( Vwork -Vmin)
Mwachitsanzo: kugwira ntchito yoyambira magetsi Vwork = 5V;voteji yodulidwa yogwira ntchito Vmin = 4.2V;nthawi yogwira ntchito t=10s;magetsi ogwira ntchito I=100mA=0.1A.Mphamvu yofunikira ndi: C =0.1*10/(5 -4.2)= 1.25F
Pankhaniyi, mukhoza kusankha mankhwala ndi capacitance wa 5.5V1.5F.
(2) Mphamvu yosalekeza, ndiko kuti, pamene mphamvu yotulutsa mphamvu imakhala yosasintha: C*ΔU2/2=PT
Mwachitsanzo, kutulutsa kosalekeza pansi pa mphamvu ya 200KW kwa masekondi 10, mtundu wamagetsi ogwirira ntchito ndi 450V-750V, capacitance yofunika: C=220kw10/(7502-4502)=11F
Choncho, capacitor (dongosolo yosungirako mphamvu) ndi capacitance ya 11F pamwamba 750V akhoza kukwaniritsa zofunika izi.
Ngati capacitance yowerengeka siili mkati mwa gawo limodzi, ma supercapacitor angapo amatha kulumikizidwa mndandanda ndi kufanana kuti apange gawo kuti akwaniritse zosowa zenizeni za makasitomala.
Njira yowerengera yofanana ya ma capacitor ambiri: C=C1+C2+C3+…+Cn
Mipikisano capacitor mndandanda wowerengera formula: 1/C=1/C1+1/C2+…+1/Cn
Malingaliro pazinthu zina
(1) Zogulitsa zamtundu wapamwamba kwambiri zimakhala ndi zabwino nthawi zambiri
Ubwino wazinthu zamagetsi zamagetsi (2.85V ndi 3.0V) ndi zotani?
Mndandanda wa moyo (1,000,000 cycle life) umakhalabe wosasinthika, ndipo mphamvu yeniyeni ndi mphamvu zenizeni zimawonjezeka pansi pa voliyumu yomweyo.
Pansi pa mphamvu ndi mphamvu zokhazikika, kuchepetsa chiwerengero cha mayunitsi ndi kulemera kwa dongosolo lonse kungathe kupititsa patsogolo mapangidwe a dongosolo.
(2) Kukwaniritsa zosowa zapadera
Pakafunika kugwiritsa ntchito mwapadera, mawu osavuta a voltage value reference alibe tanthauzo.Mwachitsanzo, kutentha pamwamba pa 65 ℃, 2.5V mndandanda wazinthu ndi chisankho chabwino.Tiyenera kuzindikira kuti, monga zigawo zonse za electrochemical, kutentha kozungulira kudzakhudza kwambiri moyo wa ma supercapacitor, ndipo moyo udzawonjezeka kawiri pa 10 ℃ iliyonse kuchepa kwa kutentha kwakukulu.
Mapangidwe ndi zipangizo za electrode za supercapacitors sizikufotokozedwa mu pepala ili, chifukwa magawo osawerengeka alibe tanthauzo lenileni la kusankha kwenikweni kwa supercapacitors.Tiyenera kukumbukira kuti palibe chipangizo chosungira mphamvu zonse, ndipo kugwiritsa ntchito zipangizo zambiri zosungiramo mphamvu zakhala chisankho chabwino kwambiri.Momwemonso, ma supercapacitor amagwiritsa ntchito zida zina zosungira mphamvu kuti apititse patsogolo zabwino zawo, ndipo akukhalanso odziwika.
Kuti mugule zida zamagetsi, muyenera kupeza wopanga wodalirika poyamba.JYH HSU(JEC) Electronics Ltd (kapena Dongguan Zhixu Electronic Co., Ltd.) ili ndi mitundu yonse yamitundumitundu ndi ma capacitor okhala ndi zotsimikizika zotsimikizika.JEC wadutsa ISO9001: 2015 khalidwe kasamalidwe dongosolo chitsimikizo.Takulandilani kuti mutilumikizane ndi zovuta zaukadaulo kapena mgwirizano wamabizinesi.Webusaiti yathu yovomerezeka: www.jeccapacitor.com
