Niaj hnub no, thaum lub zog cia khoom lag luam vam meej, supercapacitors (farad-theem capacitors) nrog lub zog cia cov yam ntxwv xws li ultra-siab zog, ultra-siab tam sim no, ultra-wide ua hauj lwm ntau, ultra-siab kev ruaj ntseg, thiab ultra-ntev lub neej yog siv. ib leeg, thiab ua ke nrog lwm cov khoom siv zog cia.Kev siv cov khoom sib xyaw ua qhov tseem ceeb.Rau cov neeg siv, nws yog ib qho tseem ceeb heev uas yuav tau xaiv ib tug haum supercapacitor.
Dab tsi scenarios yuav siv tau rau supercapacitor?
1) Lub zog siab tam sim ntawd, xws li UAV ejection ntaus ntawv;
2) Lub sijhawm luv luv tam sim no, xws li tub ceev xwm teeb nyem;
3) nquag acceleration (downward) thiab deceleration (nce) tej yam kev mob, xws li braking zog rov qab pab kiag li lawm;
4) Diesel tsheb pib nyob rau hauv huab cua txias heev los yog nyob rau hauv lub xeev ntawm roj teeb tsis ua hauj lwm;
5) Thaub qab fais fab mov rau cua fais fab tiam, hnub ci hluav taws xob hluav taws xob, hluav taws xob nuclear thiab lwm yam khoom siv hluav taws xob;
6) Txhua yam ntawm lub neej ntev, kev ntseeg siab, tsis muaj kev saib xyuas, muaj zog ceev ceev cov khoom siv hluav taws xob;
Yog tias koj xav tau ib lub cuab yeej uas muaj cov yam ntxwv ntawm lub zog siab thiab qee lub zog los tsav cov khoom siv hluav taws xob, kev tu ncua ntev-dawb, thiab muaj peev xwm ua haujlwm nyob rau hauv ntau qhov kub thiab txias, tshwj xeeb tshaj yog thaum kev nyab xeeb yuav tsum nruj me ntsis ntawm 30 mus rau 40 degrees, nws yog lub sij hawm los xaiv ib tug haum supercapacitor.
Cov ntaub ntawv koj yuav tsum paub ua ntej xaiv lub supercapacitor
Yog li dab tsi ntawm supercapacitor tuaj yeem ua tau raws li koj xav tau?Dab tsi yog qhov tseem ceeb ntawm supercapacitor?Nws lub ntsiab tsis yog voltage (V), capacitance (F) thiab ntsuas tam sim no (A).
Cov kev xav tau ntawm lub hwj chim, lub sij hawm tso tawm thiab qhov kev hloov hluav taws xob hauv qhov kev thov tshwj xeeb ntawm supercapacitors ua lub luag haujlwm txiav txim siab hauv kev xaiv cov qauv.Hauv cov ntsiab lus yooj yim, ob hom kev ntsuas yuav tsum tau teev tseg: 1) Kev ua haujlwm voltage ntau;2) Fais fab tso zis nqi los yog ntev npaum li cas cov zis tam sim no kav.
Yuav ua li cas xam qhov xav tau supercapacitor capacitance
(1) Tsis tu ncua tam sim no, uas yog, thaum lub sijhawm tam sim no thiab lub sijhawm ua haujlwm hauv supercapacitor ua haujlwm tsis tu ncua: C = Nws / (Vwork -Vmin)
Piv txwv li: ua hauj lwm pib voltage Vwork = 5V;ua hauj lwm txiav tawm voltage Vmin = 4.2V;lub sijhawm ua haujlwm t = 10s;ua hauj lwm fais fab mov I = 100mA = 0.1A.Qhov yuav tsum tau muaj peev xwm yog: C = 0.1 * 10 / (5 -4.2) = 1.25F
Hauv qhov no, koj tuaj yeem xaiv cov khoom lag luam nrog lub peev xwm ntawm 5.5V1.5F.
(2) Lub zog tsis tu ncua, uas yog, thaum lub zog tso tawm tus nqi tas li: C * ΔU2 / 2 = PT
Piv txwv li, kev tso tawm tsis tu ncua nyob rau hauv 200KW lub zog rau 10 vib nas this, qhov ua haujlwm voltage yog 450V-750V, qhov yuav tsum tau muaj peev xwm capacitance: C = 220kw10 / (7502-4502) = 11F
Yog li ntawd, lub capacitor (lub zog cia system) nrog lub peev xwm ntawm 11F saum 750V tuaj yeem ua tau raws li qhov kev thov no.
Yog hais tias tus xam capacitance tsis nyob rau hauv qhov ntau ntawm ib chav tsev, ntau lub supercapacitors tuaj yeem txuas nrog hauv series thiab sib npaug los tsim cov qauv kom tau raws li cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom.
Multi-capacitor parallel xam cov mis: C = C1 + C2 + C3 + ... + Cn
Multi-capacitor series suav cov mis: 1 / C = 1 / C1 + 1 / C2 + ... + 1 / Cn
Cov lus qhia rau lwm yam khoom
(1) High-voltage series khoom muaj qhov zoo nyob rau hauv feem ntau
Dab tsi yog qhov zoo ntawm high-voltage (2.85V thiab 3.0V) cov khoom?
Lub neej Performance index (1,000,000 lub voj voog lub neej) tseem tsis hloov, thiab lub zog tshwj xeeb thiab lub zog tshwj xeeb nce hauv tib lub ntim.
Nyob rau hauv qhov xwm txheej ntawm lub zog thiab lub zog tas li, txo cov naj npawb ntawm cov chav nyob thiab qhov hnyav ntawm tag nrho cov txheej txheem tuaj yeem ua kom zoo dua qhov tsim ntawm qhov system.
(2) Kom tau raws li cov kev xav tau tshwj xeeb
Nyob rau hauv cov ntaub ntawv ntawm daim ntawv thov tshwj xeeb yuav tsum tau, qhov yooj yim voltage siv tus nqi tsis muaj ntsiab lus.Piv txwv li, kub siab tshaj 65 ℃, 2.5V series khoom yog ib qho kev xaiv zoo.Nws yuav tsum tau muab sau tseg tias, zoo li tag nrho cov electrochemical Cheebtsam, lub ambient kub yuav zoo heev rau lub neej ntawm supercapacitor, thiab lub neej yuav tsum tau muab ob npaug rau txhua txhua 10 ℃ txo nyob rau hauv qhov kub thiab txias ib puag ncig.
Cov qauv thiab cov ntaub ntawv electrode ntawm supercapacitor tsis tau piav qhia hauv daim ntawv no, vim tias cov khoom tsis muaj qhov tsis muaj qhov tseem ceeb rau qhov kev xaiv ntawm supercapacitors.Nws yuav tsum raug sau tseg tias tsis muaj lub zog khaws cia thoob ntiaj teb, thiab kev sib xyaw ua ke ntawm ntau lub zog cia khoom tau dhau los ua qhov kev xaiv zoo tshaj plaws.Ib yam li ntawd, supercapacitors siv lwm lub zog cia khoom siv los nqa lawv tus kheej qhov zoo, thiab lawv kuj tau dhau los ua qhov tseem ceeb.
