Namhlanje, xa iimveliso zokugcina amandla zikhula, ii-supercapacitors (i-farad-level capacitors) ezineempawu zokugcina amandla njengamandla aphezulu, i-ultra-high current, i-ultra-wide work range, i-ultra-high ukhuseleko, kunye nobomi be-ultra-long busetyenziswa. yedwa, kwaye ngokudibanisa nezinye iimveliso zokugcina amandla.Ukusetyenziswa okuhlanganisiweyo kuba yinto eqhelekileyo.Kubasebenzisi, kubaluleke kakhulu ukukhetha i-supercapacitor efanelekileyo.
Zeziphi iimeko apho ii-supercapacitors ziza kusebenza kuzo?
1) Amandla aphezulu ngokukhawuleza, njengesixhobo sokukhupha i-UAV;
2)Ubonelelo lwangoku lwexeshana elifutshane, olufana nezibane zamapolisa;
I-3)Ukukhawuleza okuqhelekileyo (ezantsi) kunye neemeko zokunciphisa (phezulu), ezifana nezixhobo zokubuyisela amandla e-braking;
4)Izithuthi zedizili ziqalwa kwimozulu ebanda kakhulu okanye kwimeko yokusilela kwebhetri;
5)Gcina unikezelo lwamandla ombane oveliswa ngumoya, ukuvelisa amandla elanga, amandla enyukliya kunye nezinye iitheminali zokuvelisa amandla;
6) Zonke iintlobo zobomi obude, ukuthembeka okuphezulu, ukugcinwa kwe-free, ubuninzi bamandla okugcina amandla ombane;
Ukuba ufuna isixhobo esineempawu eziphezulu zamandla kunye nesixa esithile samandla okuqhuba izixhobo zombane, ukugcinwa kwexesha elide-free, kunye nokukwazi ukusebenza kuluhlu olubanzi lobushushu, ngakumbi xa iimfuno zokhuseleko zingqongqo kwi-minus 30 ukuya. I-40 degrees, lixesha lokukhetha i-supercapacitor efanelekileyo.
Ulwazi omele uyazi ngaphambi kokuba ukhethe i-supercapacitor
Ke luhlobo luni lwe-supercapacitor olunokuhlangabezana neemfuno zakho?Ziziphi iiparameters ezibalulekileyo ze-supercapacitors?Iiparamitha zayo eziphambili ziyi-voltage (V), i-capacitance (F) kunye ne-current rated (A).
Iimfuno zamandla, ixesha lokukhutshwa kunye notshintsho lwenkqubo yombane kwisicelo esithile se-supercapacitors sidlala indima ecacileyo ekukhetheni imodeli.Ngamagama alula, iintlobo ezimbini zeeparamitha kufuneka zichazwe: 1) Uluhlu lwe-voltage yokusebenza;2) Ixabiso lemveliso yamandla okanye ixesha elingakanani imveliso yangoku ihlala.
Indlela yokubala i-supercapacitor capacitance efunekayo
(1) I-Constant current, oko kukuthi, xa ixesha langoku kunye nobude bokusebenza kwimeko yokusebenza ye-supercapacitor ihlala: C = It / ( Vwork -Vmin)
Umzekelo: ukusebenza kombane wokuqalisa iVwork=5V;amandla ombane acinyiweyo asebenzayo Vmin=4.2V;ixesha lokusebenza t=10s;umbane osebenzayo I=100mA=0.1A.Umthamo ofunekayo ngu: C =0.1*10/(5 -4.2)= 1.25F
Kule meko, unokukhetha imveliso ene-capacitance ye-5.5V1.5F.
(2) Amandla ahlala ehleli, oko kukuthi, xa ixabiso lemveliso yombane lingaguquki: C*ΔU2/2=PT
Umzekelo, ukukhutshwa okuqhubekayo phantsi kwe-200KW amandla imizuzwana eyi-10, uluhlu lwamandla ombane osebenzayo yi-450V-750V, i-capacitance capacitance efunekayo: C = 220kw10 / (7502-4502) = 11F
Ngoko ke, i-capacitor (inkqubo yokugcina amandla) ene-capacitance ye-11F ngaphezu kwe-750V inokuhlangabezana nale mfuno.
Ukuba i-capacitance yokubalwa ayikho ngaphakathi kwinqanaba leyunithi enye, i-supercapacitors ezininzi zinokudibaniswa kwichungechunge kunye nokuhambelana nokwenza imodyuli ukuhlangabezana neemfuno ezithile zabathengi.
I-Multi-capacitor parallel formulal yokubala: C=C1+C2+C3+…+Cn
I-Multi-capacitor series formula wokubala: 1/C=1/C1+1/C2+…+1/Cn
Iingcebiso kwezinye iimveliso
(1) Iimveliso ze-high-voltage series zineenzuzo kwiimeko ezininzi
Ziziphi iingenelo ze-high-voltage (2.85V kunye ne-3.0V) iimveliso?
Isalathiso sobomi (ubomi bomjikelezo we-1,000,000) sihlala singatshintshi, kwaye amandla athile kunye namandla athile anyuka phantsi komthamo ofanayo.
Ngaphantsi kwemeko yamandla aqhubekayo kunye namandla, ukunciphisa inani leeyunithi kunye nobunzima benkqubo yonke kunokwandisa ukuyila kwenkqubo.
(2) Ukuhlangabezana neemfuno ezikhethekileyo
Kwimeko yeemfuno ezikhethekileyo zesicelo, ireferensi yexabiso lombane elula ayinantsingiselo.Umzekelo, ubushushu obuphezulu obungaphezulu kwe-65 ℃, i-2.5V yeemveliso zechungechunge lukhetho oluhle.Kufuneka kuqatshelwe ukuba, njengawo onke amacandelo e-electrochemical, ubushushu be-ambient buya kuchaphazela kakhulu ubomi be-supercapacitors, kwaye ubomi buya kuphinda-phindwe kabini kwi-10 ℃ yokuncipha kwindawo ephezulu yobushushu.
Isakhiwo kunye nezixhobo ze-electrode ze-supercapacitors azichazwanga kweli phepha, kuba iiparitha ezingenakulinganiswa zinentsingiselo encinci yokukhethwa kwangempela kwee-supercapacitors.Kufuneka kuqatshelwe ukuba akukho sixhobo sokugcina amandla kwindalo yonke, kwaye ukusetyenziswa okudibeneyo kwezixhobo ezininzi zokugcina amandla kuye kwaba yinto engcono kakhulu.Ngokufanayo, ii-supercapacitors zisebenzisa ezinye izixhobo zokugcina amandla ukuze ziqhubele phambili izibonelelo zazo, kwaye zibuye zibe yinto eqhelekileyo.
