Nidaamka Korontada 800-Volt— Furaha Gaabinta Waqtiga Dallacaadda Baabuurta Tamarta Cusub

2021, iibka caalamiga ah ee EV wuxuu xisaabin doonaa 9% wadarta iibka baabuurta rakaabka.

Si kor loogu qaado tiradaas, marka lagu daro maalgelinta ballaaran ee muuqaallada ganacsi ee cusub si loo dardargeliyo horumarinta, soo saarista iyo kor u qaadida koronto-siinta, gawaarida iyo alaab-qeybiyeyaasha ayaa sidoo kale maskaxda ku haya si ay ugu diyaar garoobaan jiilka soo socda ee qaybaha baabuurta.

Tusaalooyinka waxaa ka mid ah baytariyada gobolka adag, matoorada qulqulka axial-ka ah, iyo nidaamyada korantada ee 800-volt kuwaas oo ballan qaadaya inay jarayaan waqtiyada dallacaadda nus, si aad ah u yareeyaan cabbirka iyo qiimaha batteriga, iyo hagaajinta hufnaanta wadista.

Ilaa hadda, kaliya tiro yar oo baabuur cusub ah ayaa isticmaalay nidaamka 800-volt halkii ay ka isticmaali lahaayeen 400 ee caadiga ah.

Moodooyinka leh nidaamka 800-volt ee horeyba suuqa ugu jiray waa: Porsche Taycan, Audi E-tron GT, Hyundai Ioniq 5 iyo Kia EV6.Lucid Air limousine waxay isticmaashaa naqshad 900-volt ah, in kasta oo khubarada warshaduhu aaminsan yihiin inay farsamo ahaan tahay nidaam 800-volt ah.

Marka loo eego alaab-qeybiyeyaasha qaybaha EV, qaab-dhismeedka batteriga 800-volt wuxuu noqon doonaa tignoolajiyada ugu weyn dhamaadka 2020-meeyada, gaar ahaan sida aad iyo aad uga sii go'an tahay 800-volt qaab-dhismeedka dhammaan aaladaha korontada ku shaqeeya, sida Hyundai's E-GMP iyo PPE Kooxda Volkswagen.

Hyundai Motor's E-GMP module koronto ah waxaa bixiya Vitesco Technologies, shirkad powertrain ah oo ka soo baxday Continental AG, si ay u bixiso 800-volt rogayaasha;Kooxda Volkswagen PPE waa batari 800-volt ah oo ay si wadajir ah u soo saareen Audi iyo Porsche.Qalabka korantada ee modulka ah.

"Marka la gaaro 2025, moodooyinka leh nidaamyada 800-volt waxay noqon doonaan kuwo caan ah," ayuu yiri Dirk Kesselgruber, oo ah madaxa GKN qaybteeda wadista gawaarida korontada, shirkad horumarinta tignoolajiyada.GKN sidoo kale waa mid ka mid ah alaab-qeybiyeyaal dhowr ah oo Tier 1 ah oo isticmaalaya tignoolajiyada, oo siinaya qaybo ay ka mid yihiin 800-volt axles koronto, oo isha ku haya wax soo saarka ballaaran ee 2025.

Waxa uu u sheegay Automotive News Europe, "Waxaan u maleyneynaa in nidaamka 800-volt uu noqon doono mid guud. Hyundai ayaa sidoo kale caddeeyey in ay si siman ugu tartami karto qiimaha."

Dalka Maraykanka, Hyundai IQNIQ 5 waxa uu ka bilaabmaa $43,650, taas oo ka badan qiimaha celceliska $60,054 ee baabuurta korontada ku shaqeeya February 2022, oo ay aqbali karaan macaamiil badan.

"800 volts waa tallaabada xigta ee macquulka ah ee horumarinta baabuurta korantada saafiga ah," Alexander Reich, oo ah madaxa qalabka korontada ee casriga ah ee Vitesco, ayaa ku sheegay wareysi.

Marka lagu daro bixinta 800-volt inverters ee Hyundai's E-GMP qaab korantada, Vitesco waxay xaqiijisatay qandaraasyo kale oo waaweyn, oo ay ku jiraan rogayaasha baabuurta waaweyn ee Waqooyiga Ameerika iyo laba EVs hormuudka ka ah Shiinaha iyo Japan.Alaab-qeybiyaha ayaa bixiya mootada.

Qeybta nidaamyada korantada ee 800-volt waxay u kordheysaa si ka dhakhso badan sidii la filayay dhowr sano ka hor, macaamiishana way sii xoogeysanayaan, Harry Husted, madaxa tignoolajiyada ee alaab-qeybiyaha Mareykanka ee BorgWarner, ayaa ku yiri iimaylka.xiisaha.Alaab-qeybiyaha ayaa sidoo kale ku guuleystay qaar ka mid ah dalabaadka, oo ay ku jiraan moduleka wadista isku dhafan ee sumadda raaxada ee Shiinaha.

1. Maxay 800 volts u tahay "tallaabada xigta ee macquulka ah"?

 

Maxay yihiin waxyaabaha ugu muhiimsan ee nidaamka 800-volt marka la barbar dhigo nidaamka 400-volt ee jira?

Marka hore, waxay awood isku mid ah ku bixin karaan hadda hoose.Ku kordhi wakhtiga dallacaadda 50% oo leh cabbirka batari la mid ah.

Natiijo ahaan, batteriga, qaybta ugu qaalisan ee gawaarida korantada, ayaa laga dhigi karaa mid yar, kordhinta waxtarka iyada oo la yareeyo miisaanka guud.

Otmar Scharrer, oo ah madaxweyne ku xigeenka sare ee tignoolajiyada tamarta korantada ee ZF, ayaa yidhi: "Qiimaha baabuurta korontadu weli ma aha heer la mid ah baabuurta shidaalka, iyo baytari yar ayaa noqon lahaa xal wanaagsan. Sidoo kale, haysashada batari aad u weyn Qaabka guud ee isafgaradka ah sida Ioniq 5 laftiisu macno ma samaynayo."

"Iyadoo la labanlaabo korontada iyo isla hadda, baabuurka wuxuu heli karaa labanlaab tamar ka badan," ayuu yiri Reich."Haddii wakhtiga dallacadu uu yahay mid degdeg ah, baabuurka korantada ayaa laga yaabaa inuusan u baahnayn inuu waqti ku qaato raadinta masaafo dhan 1,000 kiiloomitir."

Marka labaad, sababtoo ah korantada sare waxay bixisaa awood isku mid ah oo leh hadda yar, fiilooyinka iyo fiilooyinka ayaa sidoo kale laga dhigi karaa kuwo yaryar oo fudud, yareynta isticmaalka qaaliga iyo naxaasta culus.

Tamarta lunta ayaa sidoo kale loo dhimi doonaa si ku habboon, taasoo keenaysa dulqaad wanaagsan iyo horumarinta waxqabadka dhaqdhaqaaqa.Mana jirto nidaam maaraynta kulaylka adag oo loo baahan yahay si loo hubiyo in batarigu ku shaqeeyo heerkulka ugu fiican.

Ugu dambeyntii, marka lagu daro tignoolajiyada soo ifbaxa ee silikoon carbide microchip, nidaamka 800-volt wuxuu kordhin karaa waxtarka tamarta ilaa 5 boqolkiiba.Chip-kani waxa uu lumiyaa tamar yar marka uu beddelanayo waxana uu si gaar ah waxtar ugu leeyahay bareegga dib-u-kicinta.

Sababtoo ah chips-ka silikoon carbide-ka cusub waxay isticmaalaan silikon saafi ah oo ka yar, qiimuhu wuu yarayn karaa oo jajabyo badan ayaa la siin karaa warshadaha baabuurta, alaab-qeybiyeyaashu waxay yiraahdeen.Sababtoo ah warshadaha kale waxay u muuqdaan inay isticmaalaan dhammaan chips-silicon, waxay kula tartamayaan baabuurta sameeya khadka wax soo saarka semiconductor.

"Gabagabadii, horumarinta nidaamyada 800-volt waa muhiim," ayuu GKN's Kessel Gruber ku soo gabagabeeyay.

 

2. 800-volt qaabeynta saldhiga dallacaadda

 

Waa tan su'aal kale: Inta badan xarumaha dallaca ee jira waxay ku saleysan yihiin nidaamka 400-volt, runtii faa'iido ma u leedahay baabuurta isticmaalaya nidaamka 800-volt?

Jawaabta ay bixiyeen khubarada warshaduhu waa: haa.In kasta oo baabuurku u baahan yahay kaabayaal dallacaad ku salaysan 800-volt.

"Inta badan kaabayaasha dhaqaale ee degdegga ah ee DC ee jira waxaa loogu talagalay baabuurta 400-volt," ayuu yiri Hursted."Si loo gaaro dallacaadda degdega ah ee 800-volt, waxaan u baahannahay jiilkii ugu dambeeyay ee korantada sare, awoodda sare ee DC-xajiyeyaasha degdega ah."

Taasi dhib kuma aha dallacaadda guriga, laakiin ilaa hadda shabakadaha dallacaadaha dadweynaha ee ugu dhaqsaha badan Maraykanka ayaa xaddidan.Reich waxa uu qabaa in dhibaatadu ay xitaa ku adag tahay saldhigyada dallaca ee wadooyinka.

Yurub dhexdeeda, si kastaba ha ahaatee, shabakadaha dallacaadda ee 800-volt ayaa kor u kacaya, Ionity-na waxa ay leedahay tiro 800-volt ah, 350-kilowatt ah oo ku dallaca meelaha Yurub oo dhan.

Ionity EU waa mashruuc shuraako badan oo automaker ah oo loogu talagalay shabakad awood sare leh oo lagu dallaco baabuurta korontada, oo ay aasaaseen BMW Group, Daimler AG, Ford Motor iyo Volkswagen.Sanadka 2020, Hyundai Motor wuxuu ku biiray saamilayda shanaad ee ugu wayn.

"Xeeriyaha 800-volt, 350-kilowatt macnaheedu waa 100-kilomitir oo dalacsiin ah oo ah 5-7 daqiiqo," ayuu yiri ZF's Schaller."Taasi waa koob kafee ah oo kaliya."

"Tani runtii waa tignoolajiyada carqaladaynaysa. Waxay sidoo kale ka caawin doontaa warshadaha baabuurta inay dad badan ku qanciyaan inay qaataan gawaarida korontada."

Sida laga soo xigtay warbixin dhowaan ka soo baxday Porsche, waxay qaadataa ilaa 80 daqiiqo in lagu daro 250 mayl oo kala duwan oo ah xarun koronto oo 50kW ah, 400V;40 daqiiqo haddii ay tahay 100kW;Haddii la qaboojiyo furka dallacaadda (qiimaha, miisaanka iyo kakanaanta), taas oo sii yareyn karta wakhtiga 30 daqiiqo.

"Sidaas darteed, raadinta si loo gaaro dallacaadda xawaaraha sare leh, u gudubka tamarta sare waa lama huraan," ayaa lagu soo gabagabeeyay warbixinta.Porsche wuxuu aaminsan yahay in korantada ku dallaca 800-volt, waqtigu hoos ugu dhici doono ilaa 15 daqiiqo.

Ku dallacida sida fudud oo degdega ah sida shidaalka - waxaa jirta fursad wanaagsan inay dhacdo.

3. Hormoodka warshadaha muxaafidka ah

 

Haddii tignoolajiyada 800-volt runtii aad u wanaagsan tahay, waxaa habboon in la is weydiiyo sababta, marka laga reebo moodooyinka aan soo sheegnay, ku dhawaad ​​​​dhammaan baabuurta korantada ayaa wali ku saleysan nidaamyada 400-volt, xitaa hogaamiyayaasha suuqa Tesla iyo Volkswagen.?

Schaller iyo khubarada kale waxay sababaha u nisbeeyaan "fududeynta" iyo "inaad noqoto warshad marka hore."

Guriga caadiga ah wuxuu isticmaalaa 380 volts oo ah saddex-waji AC ah (heerka korantada dhab ahaantii waa kala duwanaansho, ma aha qiime go'an), markaa markii baabuur-sameeyayaashu bilaabeen inay soo rogaan isku-dhafka isku-dhafka ah iyo baabuurta korantada ee saafiga ah, kaabayaasha dallacadu horay ayay u jireen.Iyo mowjadihii ugu horreeyay ee baabuurta korontada ku shaqeeya ayaa lagu dhisay qaybo loo sameeyay isku-dhafka isku-dhafka ah, kuwaas oo ku salaysan nidaamka 400-volt.

"Marka qof kastaa uu ku jiro 400 volts, waxay la macno tahay in heerka korantada ee laga heli karo kaabayaasha meel walba," ayuu yiri Schaller."Waa tan ugu habboon, isla markiiba waa la heli karaa. Markaa dadku wax badan kama fikiraan. Isla markiiba go'aansadeen."

Kessel Gruber wuxuu ku qiimeeyay Porsche inuu yahay hormuudka nidaamka 800-volt sababtoo ah waxay diiradda saartay wax qabad marka loo eego waxqabadka.

Porsche waxay ku dhiirran tahay inay dib u qiimeyso waxa warshaduhu ka soo qabteen wixii la soo dhaafay.Waxa uu is weydiinayaa: "Runtii kani ma yahay xalka ugu fiican?""Miyaan ka naqshadeyn karnaa meel eber?"Taasi waa quruxda ka mid noqoshada baabuur-sameeyaha waxqabadka sarreeya.

Khubarada warshadaha ayaa isku raacay in ay tahay arrin wakhti uun ka hor inta 800-volt EVs ay suuqa soo gelin.

Ma jiraan caqabado badan oo farsamo, laakiin qaybo ayaa u baahan in la horumariyo oo la ansixiyo;Qiimuhu wuxuu noqon karaa arrin, laakiin miisaanka, unugyada yaryar iyo naxaasta ka yar, kharash yar ayaa iman doona dhawaan.

Volvo, Polestar, Stellantis iyo General Motors ayaa horey u sheegay in moodooyinka mustaqbalka ay isticmaali doonaan tignoolajiyada.

Kooxda Volkswagen waxa ay qorshaynaysaa in ay ku soo bandhigto gawaadhi kala duwan 800-volt PPE madalkeeda, oo ay ku jiraan Macan cusub iyo gaadhi boosteejo ah oo ku salaysan fikradda cusub ee A6 Avant E-tron.

Tiro ka mid ah baabuurta Shiinaha ayaa sidoo kale ku dhawaaqay inay u guurayaan 800-volt architecture, oo ay ku jiraan Xpeng Motors, NIO, Li Auto, BYD iyo Lotus uu Geely leeyahay.

"Taycan iyo E-tron GT, waxaad haysataa baabuur leh waxqabadka hogaaminta fasalka. Ioniq 5 waa caddaynta in baabuur qoys oo la awoodi karo uu suurtogal yahay," ayuu Kessel Gruber ku soo gabagabeeyey."Haddii baabuurtan yar ay samayn karaan, markaa baabuur kasta wuu samayn karaa."
