Iyadoo ay jirto cilmi-baaris muujinaysa in degdegga badan (DC) ku dallacadu ay xoogaa hoos u dhigi karto batteriga si ka dhakhso badanKu dallaca AC, Saamaynta kulaylka batteriga aad bay u yar tahay. Dhab ahaantii, dallacaadda DC waxay kordhisaa xumaanshaha batteriga qiyaastii 0.1 boqolkiiba celcelis ahaan.
In si fiican loola dhaqmo baytarigaaga wax badan ayay ka qabtaa maaraynta heerkulka marka loo eego wax kasta oo kale, maadaama baytariyada lithium-ion (Li-ion) ay xasaasi u yihiin heerkulka sare. Nasiib wanaag, ugu casrisanEVswaxay leeyihiin habab maareyn heerkul ku dhex dhisan si ay u ilaaliyaan batteriga, xitaa marka si degdeg ah loo dallaci doono.
Mid ka mid ah welwelka caadiga ah ayaa ah agagaarka saameynta ku dallacaadda degdega ah ee xaalufka batteriga - walaac la fahmi karo marka la eego taasXajiyeyaasha EVsoosaarayaasha sida Kia iyo xitaa Tesla waxay ku talinayaan isticmaalka dallaca degdega ah ee sharraxaadda faahfaahsan ee qaar ka mid ah moodooyinkooda.
Haddaba waa maxay saamaynta degdegga ah ee ku dallacaadda batterigaaga, oo ma saamaynaysaa caafimaadka batterigaaga? Maqaalkan, waxaan ku kala jebin doonaa sida degdega ah ee dallacadu u shaqeyso una sharaxno inay badbaado tahay in loo isticmaalo EV-gaaga.
Waa maxaydallacaadda degdega ah?
Kahor intaanan isku dayin in aan ka jawaabno in dallacaadda degdega ah ay badbaado u tahay EV-gaaga, waxaan marka hore u baahannahay inaan sharaxno waxa ku dallacaadda degdega ah ay tahay meesha ugu horeysa. Dallacaadda degdegga ah, oo sidoo kale loo yaqaanno heerka 3 ama dallacaadda DC, waxaa loola jeedaa saldhigyada dallacaadda ee ugu dhaqsaha badan ee la heli karo kuwaas oo ku dallaci kara EV-gaaga daqiiqado beddelka saacado.
Wax soo saarka korontadu way kala duwan yihiinsaldhigyada dallacaadda, laakiin dabaysha degdega ah ee DC waxay keeni kartaa inta u dhaxaysa 7 iyo 50 jeer ka awood badan saldhiga caadiga ah ee AC. In kasta oo awooddan sare ay ku fiican tahay in si dhakhso ah kor loogu qaado EV, waxay sidoo kale dhalinaysaa kuleyl aad u badan waxayna batteriga gelin kartaa walaac.
Saamaynta ku dallacaadda degdega ah ee baytariyada baabuurta korontada
Haddaba, waa maxay xaqiiqada ku saabsan saamaynta degdegga ah ee dallacaaddaEV bataricaafimaadka?
Daraasadaha qaarkood, sida cilmi-baarista Geotab ee laga soo bilaabo 2020, ayaa lagu ogaaday in muddo laba sano ah, ku dallaca degdega ah in ka badan saddex jeer bishii ay kordhisay xaalufka batteriga 0.1 boqolkiiba marka loo eego darawallada aan waligood isticmaalin dallaca degdega ah.
Daraasad kale oo ay samaysay Shaybaadhka Qaranka ee Idaho (INL) ayaa tijaabiyay laba lammaane oo Nissan Leafs ah, iyaga oo ku dallacay laba jeer maalin kasta sannadkii, iyada oo hal lammaan oo keliya ay isticmaaleen ku dallaca AC caadiga ah halka kan kalena si gaar ah u isticmaalay DC si degdeg ah.
Ku dhawaad 85,000 kiiloomitir oo ay jidka ku jireen, labada qof ee lagu dallacay kaliya iyaga oo isticmaalaya xajiyeyaasha degdega ah ayaa lumiyay 27 boqolkiiba awoodoodii asalka ahayd, halka labada isticmaale ee AC ku dallacay ay lumiyeen boqolkiiba 23 awoodda baytarigoodii ugu horreeyay.
Sida labada daraasadoodba muujinayaan, dallacaadda degdegga ah ee joogtada ah waxay hoos u dhigtaa caafimaadka batteriga in ka badan ku dallaca AC, in kasta oo saameynteedu ay weli tahay mid aad u yar, gaar ahaan marka la tixgeliyo xaaladaha nolosha dhabta ah ee ka baahi yar batteriga marka loo eego tijaabooyinkan la kantaroolo.
Marka, ma tahay inaad si degdeg ah u dallacato EV-gaaga?
Dallacaadda heerka 3 waa xal ku habboon in si degdeg ah kor loogu qaado socodka, laakiin ficil ahaan, waxaad u badan tahay inaad ogaato in dallacaadda AC ee joogtada ahi ay si ku filan u buuxiso baahiyahaaga maalinlaha ah.
Dhab ahaantii, xitaa heerka ugu hooseeya ee 2 dallacaadda, cabbir dhexdhexaad ah EV ayaa weli si buuxda loo dalaci doonaa wax ka yar 8 saacadood, markaa isticmaalka degdegga ah uma badna inay noqoto waayo-aragnimo maalinle ah dadka intooda badan.
Sababtoo ah dabaysha degdega ah ee DC ayaa aad uga culus, qaali ah in la rakibo, waxayna u baahan yihiin koronto aad u sareysa si ay u shaqeeyaan, kaliya waxaa laga heli karaa meelo gaar ah, waxayna u muuqdaan kuwo aad uga kharash badan isticmaalkaSaldhigyada dallaca dadweynaha ee AC.
Horumarka ku dallacaadda degdega ah
Mid ka mid ah qaybahayada muuqaalka tooska ah ee REVOLUTION Live podcast, FastNed's Head of Charging Technology, Roland van der Put, wuxuu iftiimiyay in badi baytariyada casriga ah loo qorsheeyay in si degdeg ah loo dallaco oo ay leeyihiin habab qaboojin isku dhafan si ay u xakameeyaan culeyska sare ee korontada degdegga ah.
Tani muhiim ma aha oo kaliya dallacaadda degdega ah, laakiin sidoo kale xaaladaha cimilada aadka u daran, batterigaaga EV waxa uu la kulmi doonaa qabow aad u qabow ama heerkul aad u kulul. Dhab ahaantii, batterigaaga EVs-ku wuxuu si wanaagsan ugu shaqeeyaa heerkul cidhiidhi ah oo u dhexeeya 25 iyo 45°C. Nidaamkani waxa uu u ogolaanayaa gaadhigaaga in uu sii shaqeeyo oo uu ku dallaco heerkul hoose ama sare laakiin waxa laga yaabaa in uu kordhiyo wakhtiyada lacag bixinta haddii heerkulku ka baxsan yahay heerka ugu fican.
