Ukutshintshela kwihlabathi jikelele kwizithuthi zamandla amatsha (NEVs) ayiseyiyo into efunekayo-kuyimfuneko. Njengoko ii-automakers zibaleka ukwakha izithuthi zombane ezisebenza kakuhle, ezithembekileyo, nezizinzileyo, onke amacandelo kwinkqubo yamandla iba likhonkco elibalulekileyo kwikhonkco. Phakathi kwezi,iibhasi zebhasi eziguquguqukayo zobhedubagqame njengamagorha angakhange adunyiswe: "zezindlela ze-eneji" ezihambisa imisinga ephezulu phakathi kwebhetri, i-inverter, kunye nemoto{0}}ngaphandle kokuba i-NEV ingakwazi ukuhamba. Kodwa nantsi into yokubambisa: ukuvelisa{2}}iibhasi zebhasi eziguquguqukayo eziphezulu akukho lula. Iindlela zewelding zesiNtu zihlala zisilela ekuhlangabezaneni neemfuno ezingqongqo zeshishini le-NEV zokuqhuba, ukomelela, kunye nokuqina. KulaphoUmatshini weWelding we-HAIFEIingena. Njengenkokeli kubuchwephesha bokuwelda, izisombululo ze-HAIFEI zokusasazwa kwe-welding zilungiselelwe ukusombulula imiceli mngeni eyodwa yokuveliswa kwebhasi yebhasi ebhetyebhetye, ukuqinisekisa amacandelo akho e-NEV anikezela ngokuqhubekayo,-ukusebenza okuhlala ixesha elide.
Kutheni iCopper Flexible Busbars Ingaxoxiswana-i-NEVs
Phambi kokuntywila kwindlela umatshini we-HAIFEI oyiguqula ngayo imveliso, masiqale siqonde ukuba kutheniiibhasi zebhasi eziguquguqukayo zobheduziyimfuneko kwiiNEVs. Ngokungafaniyo nepetroli yesintu{1}imoto ezinenjini{2}}apho amandla ahamba ukusuka ekutshisweni kwamafutha ukuya kwintshukumo yoomatshini{3}}ii-NEV zixhomekeke ngokupheleleyo kumbane. Oku kuthetha ukuba yonke i-ampere yangoku esuka kwibhetri kufuneka ihanjiswe ngokufanelekileyo kwi-motor, kwaye nakuphi na ukungasebenzi (njengokuchasana okuphezulu kuqhagamshelwano) kunokukhokelela kuluhlu oluncitshisiweyo, ukutshaja okucothayo, okanye ukusilela kwecandelo.
Ubhedu luyinto efanelekileyo kulo msebenzi. Njengomqhubi, unomnye weyona ndlela iphantsi yokumelana nayo nayiphi na isinyithi, eqinisekisa ukulahlekelwa kwamandla amancinci ngexesha lokudluliselwa. Kodwa ii-NEV azifuni nje iintsimbi zobhedu eziqinileyo{2}}zifuna ubhetyebhetye. Iipakethi zebhetri, ii-inverters, kunye neenjini zihlala zibekwe kwindawo ezixineneyo, ezingaqhelekanga, kwayeiibhasi zebhasi eziguquguqukayo zobhedu(eyenziwe kwiifoyile zobhedu ezinomaleko okanye imicu yobhedu ebhityileyo) inokugoba kwaye ihambelane nolu cwangciso ngaphandle kokuphazamisana ne-conductivity. Zikwafunxa nokungcangcazela kwintshukumo yesithuthi, nto leyo ethintela ukuqhekeka koxinzelelo kumalungu e-solder athwaxa uqhagamshelo oluqinileyo.
Ngaphaya kwe-NEVs,iibhasi zebhasi eziguquguqukayo zobheduzisetyenziswa{{0}kusetyenziso lwangoku oluphezulu njengeenguqu kwimizi-mveliso, iinkqubo zokugcina amandla, kunye nezikhululo zokutshaja zombane{1}kodwa indima yazo kwii-NEVs ibalulekile. Kubenzi beemoto kunye nabanikezeli becandelo, injongo icacile: ukuvelisa iibhasi ze-1) eziqhuba kakhulu (ezihambelana nokusebenza kobhedu olusisiseko), i-2) yomelele ngokwaneleyo yokumelana neminyaka yokungcangcazela, kunye ne-3) ehambelana ngokwaneleyo kwimveliso yobuninzi. Iindlela zokuwelding zemveli ziyasokola ukuhlangabezana nazo zontathu.
Unyino lweWelding yesiNtu kwiiBusbars zeCopper Flexible
Makhe sithethe ngemingeni yokuweldaiibhasi zebhasi eziguquguqukayo zobhedungobuchule obuqhelekileyo. Umzekelo, okuphakathi{1}}ukuwelda kwebala (indlela eqhelekileyo yeendawo eziqinileyo zobhedu) ifuna ukongeza isithambiso sokubopha ukubopha ubhedu{2}}ukuya{3}}kobhedu. Ngelixa oku kusebenzela uqhagamshelo olulula, inezithintelo ezinkulu kwiibhasi eziguquguqukayo:
- Ukwanda koKuchasa: Isihluzi sebrazing (esidla ngokuba yicopper{0}}ingxubevange yesilivere) inokumelana okuphezulu kunobhedu olusulungekileyo. Nokuba umaleko obhityileyo unokudala "ukumelana nebhotile" kwi-busbar, okukhokelela ekulahlekeni kwamandla kunye nokwanda kobushushu{2}}imingcipheko emibini i-NEVs engenako ukuyifikelela.
- Ubuqhophololo: Iintsimbi zokuzalisa aziguquguquki kakhulu kunobhedu olucocekileyo. Ngokuhamba kwexesha, njengoko i-busbar ishukuma kwisithuthi, i-filler joint ingaqhekeka, ibangele ukusilela kombane okanye iingozi zokhuseleko.
- Ukungangqinelani: I-Spot welding ixhomekeke kubushushu obuchanekileyo kunye nolawulo loxinzelelo, kodwa i-copper ephezulu ye-thermal conductivity ithetha ubushushu buyaphela ngokukhawuleza. Oku kukhokelela kwiiwelds ezingalinganiyo, ngakumbi kwiifoyile zobhedu ezinomaleko kwiibhasi eziguquguqukayo.
Olunye ukhetho, i-ultrasonic welding, isebenzela ubhedu olucekethekileyo lwezicelo kodwa iyasokola ngokungqindilili,-kwangoku kweebhasi zebhasi. Ihlala ishiya umonakalo ongaphezulu okanye ukudibanisa okungaphelelanga, okuyi-dealbreaker kumacandelo e-NEV ekufuneka aphumelele uphicotho olungqongqo lwekhwalithi (njenge-ISO 15500 yamacandelo emoto yombane).
Ngoko ke, siyintoni isisombululo? Indlela ye-welding edibanisa ubhedu ngaphandle kweentsimbi zokuzalisa, igcina i-conductivity, kwaye idala amajoyina aguquguqukayo, ahlala ixesha elide. Yiloo nto kanye eyenziwa yi-diffusion welding-kwayeUmatshini weWelding we-HAIFEIyenzelwe ukugqwesa le nkqubo yeebhasi zebhasi eziguquguqukayo.
