Markay timaaddo 800V, shirkadaha baabuurta ee hadda jira waxay inta badan kor u qaadaan 800V ee dallaca degdega ah, iyo macaamiishu si hoose ayay u malaynayaan in 800V uu yahay nidaamka dallacaadda degdegga ah.
Dhab ahaantii, fahamkan waa mid si khaldan loo fahmay.Si aad u noqoto mid sax ah, 800V korantada degdega ah ee degdega ah waa mid ka mid ah sifooyinka nidaamka 800V.
Maqaalkan, waxaan rabaa inaan si nidaamsan u tuso akhristayaasha nidaam 800V ah oo dhammaystiran oo ka yimid shan cabbir, oo ay ku jiraan:
1. Waa maxay nidaamka 800V ee gaadhiga tamarta cusub?
2. Waa maxay sababta 800V loo soo bandhigay xilligan?
3. Waa maxay faa'iidooyinka dareenka leh ee nidaamka 800V hadda keeni karaa?
4. Waa maxay dhibaatooyinka ku jira codsiga nidaamka 800V ee hadda jira?
5. Waa maxay qaabka suurtogalka ah ee dallacaadda mustaqbalka?
01.Waa maxay nidaamka 800V ee gaariga tamarta cusub?
Nidaamka korantada sare waxaa ka mid ah dhammaan qaybaha korantada sare ee goobta sare ee korontada. Jaantuska soo socdaa wuxuu muujinayaa qaybaha korantada sare ee caadiga ahtamarta cusub gaari koronto saafi ahku qalabaysan madal danab 400V-qaboojiyeyxirmo batari.
Goobta korantada ee nidaamka-voltage-ka sare waxaa laga soo qaatay danab soo-saarka xirmada baytariga awoodda baabuurta.
Kala duwanaanshaha korantada gaarka ah ee noocyada kala duwan ee korantada saafiga ah waxay la xiriirtaa tirada unugyada taxanaha ah ee xirmada batari kasta iyo nooca unugyada (ternary, lithium iron phosphate, iwm.).
Waxaa ka mid ah, tirada xirmooyinka batteriga ternary ee taxane ah oo leh 100 unug waa qiyaastii 400V danab sare.
Qalabka korantada ee 400V ee aynu inta badan nidhaahno waa erey ballaadhan. Qaado tusaale ahaan 400V platform Jikrypton 001. Marka xirmada batteriga ternary uu sido waxay ka socotaa 100% SOC ilaa 0% SOC, ballaciisa isbeddelka danabku wuu ku dhow yahay100V (qiyaastii 350V-450V). ).
Sawir 3D ah xirmo batari danab sare leh
Marka la eego goobta hadda jirta ee 400V, dhammaan qaybaha iyo qaybaha nidaamka korantada sare waxay ka shaqeeyaan heerka korantada 400V, naqshadeynta cabbirka, horumarinta iyo xaqiijinta waxaa lagu fuliyaa iyadoo loo eegayo heerka korantada 400V.
Si loo gaaro nidaam madal koronto-sare ah oo 800V ah, ugu horreyntii, marka la eego korantada xirmada batteriga, baakidh 800V ah ayaa loo baahan yahay in la isticmaalo, oo u dhiganta ilaa 200ternary lithiumunugyo batari oo taxane ah.
Waxaa la socda matoorrada, qaboojiyeyaasha, dabaylaha, taageerada DCDC 800V iyo xadhkaha fiilooyinka la xidhiidha, isku xidhayaasha korantada sare iyo qaybaha kale ee dhammaan wareegyada korantada sare ayaa loo qaabeeyey, la sameeyay oo la xaqiijiyay si waafaqsan shuruudaha 800V.
Horumarinta qaab dhismeedka madal 800V, si ay ula jaanqaadaan 500V/750V xirmooyinka degdega ah ee suuqa, 800V baabuurta korantada saafiga ah waxaa lagu qalabayn doonaa 400V ilaa 800V modules kor u DCDCmuddo dheer.
Shaqadeedu waa ingo'aanso waqti ku filan in la dhaqaajiyo moduleka kor u qaadista si loogu dallaco batteriga 800V iyadoo loo eegayo awoodda korantada dhabta ah eedallacsiinta .
Marka loo eego isku darka waxqabadka kharashka, waxaa jira qiyaas ahaan laba nooc:
Mid ka mid ah waa qaab-dhismeedka 800V oo buuxa.
Dhammaan qaybaha baabuurta ee dhismahan waxaa loogu talagalay 800V.
Full 800V dhismaha nidaamka danab sare
Qaybta labaad waa qaybta wax ku oolka leh ee dhismaha 800V.
Hayso qaybo 400V ah: Maaddaama qiimaha hadda jira ee 800V ee qalabka beddelka awoodda uu yahay dhowr jeer oo ka mid ah 400V IGBTs, si loo dheellitiro qiimaha baabuurka oo dhan iyo hufnaanta wadista, OEM-yada waxaa lagu dhiirigeliyaa inay isticmaalaan qaybaha 800V.(sida matoorada)onHayso qaybo 400V ah(tusaale qaboojiyaha korontada, DCDC).
Isku dhufashada qalabka korontadaMaaddaama aysan jirin baahi loo qabo in la wado inta lagu jiro habka dallacaadda, OEM-yada qiimaha leh ayaa dib u isticmaali doona aaladaha korantada ee matoorka dabada dambe ee 400V-800 kor u qaadista DCDC.
Nidaamka Awooda 800V Platform Architecture
02.Maxay tahay sababta baabuurta tamarta cusub ay u soo bandhigaan nidaamyada 800V xilligan?
Wadista maalinlaha ah ee baabuurta korantada saafiga ah ee hadda, ku dhawaad 80% korontadu waxa ay ku isticmaashaa matoorka.
Inverter-ka, ama kantaroolaha mootada, ayaa maamula mootada korontada waana mid ka mid ah qaybaha ugu muhiimsan ee gaariga.
Saddex-in-hal nidaamka wadista koronto
Xilligii Si IGBT, hagaajinta hufnaanta ee 800V madal koronto-sare waa mid yar, iyo awoodda codsigu kuma filna.
Luminta waxtarka ee nidaamka mootada wadista waxay inta badan ka kooban tahay luminta jidhka mootada iyo luminta beddelka:
Qaybta koowaad ee khasaaraha - luminta jidhka matoorka:
- Naxaasta luminta - kulaylka oo lumayamatoorka istoorka(silig naxaas ah);
- Luminta birta Nidaamyada uu matoorku isticmaalo xoog birlabeed, luminta kulaylka(Kuleylka Joule)oo ay sababto qulqulka qulqulka ee ka dhasha birta(ama aluminium)qayb ka mid ah matoorka sababtoo ah isbeddelka xoogga magnetic;
- Khasaaraha khaldan waxaa loo aaneynayaa khasaaraha ka dhashay qulqulka aan joogtada ahayn;
- luminta dabaysha.
Nooc gaar ah oo ah 400V matoorka fidsan sida soo socota ayaa leh waxtarka ugu badan ee 97%, iyo 400V Extreme Krypton 001 Wei Rui motor jirka ayaa la sheegay inuu leeyahay waxtarka ugu badan ee 98%.
Marxaladda 400V, oo gaadhay waxtarka ugu sarreeya ee 97-98%, si fudud loo isticmaalo 800V platform waxay leedahay meel xaddidan si loo yareeyo khasaaraha mashiinka laftiisa.
Qeybta 2 Khasaaraha: Khasaaraha Wareegtada Matoorka:
- luminta habdhaqanka;
- beddelidda khasaaraha.
Kuwa soo socda waaHonda400V madal IGBT hufnaanta beddelka matoorka Map[1].In ka badan 95%aagagga waxtarka sare leh waxay ku dhow yihiin 50%.
Marka la barbardhigo heerka khasaaraha hadda ee labada qaybood:
Isbarbardhigga qalafsan ee u dhexeeya luminta jidhka mootada (> 2%)iyo luminta matoorka beddelka(> 4%), khasaaraha inverter waa mid aad u weyn.
Sidaa darteed, kala duwanaanshaha wadista baabuurku waxay aad ugu xiran tahay waxtarka beddelka ugu weyn ee mashiinka wadista.
Kahor inta uusan qaan gaarin semiconductor-ka awooda seddexaad ee SiC MOSFET, qaybaha awooda gawaarida tamarta cusub, sida matoorka wadista, waxay u adeegsadaan Si IGBT sida aaladda wareejinta, iyo heerka korantada ee taageeraya inta badan waa 650V. Xirmooyinka korontadu, mashiinnada korantada iyo dhacdooyinka kale ee aan la isticmaalin.
Marka laga eego aragtida suurtogalka ah, gaadhi rakaab cusub oo tamar ah ayaa aragti ahaan u isticmaali kara IGBT oo leh danab adkeysi u leh 1200V sida daaran korantada ee 800V matoorka kontoroolka, iyo nidaamka 800V ayaa la horumarin doonaa xilliga IGBT.
Marka loo eego waxqabadka qiimaha, madal koronto 800V waxay leedahay horumar xaddidan ee hufnaanta jirka. Isticmaalka joogtada ah ee 1200V IGBTs ma wanaajiso waxtarka rogaha matoorka, kaas oo xisaabiya inta badan khasaaraha. Taa beddelkeeda, waxay keenaysaa kharashyo horumarineed oo taxane ah. Inta badan shirkadaha baabuurta ma laha codsi koronto xilligii IGBT. 800V madal.
Xilligii SiC MOSFETs, waxqabadka nidaamyada 800V ayaa bilaabay in la hagaajiyo sababtoo ah dhalashada qaybaha muhiimka ah.
Ka dib imaatinka jiilka saddexaad ee semiconductor qalabka silikon carbide, waxay heshay fiiro gaar ah sababtoo ah sifooyinkeeda ugu wanaagsan [2].Waxay isku daraysaa faa'iidooyinka soo noqnoqda sare ee Si MOSFETs iyo danab sare Si IGBTs:
- Inta jeer ee hawlgalka sare - ilaa heerka MHz, xorriyadda habaynta sare
- Iska caabin danab wanaagsan - ilaa 3000 kV, xaaladaha codsiga ballaaran
- Iska caabbinta heerkulka wanaagsan - waxay ku socon kartaa si deggan heerkulka sare ee 200 ℃
- Cabbir yar oo isku dhafan - heerkulka hawlgalka sare wuxuu yareeyaa cabbirka heatsink iyo miisaanka
- Hufnaanta Hawleed Sare - Qaadashada aaladaha korantada ee SiC waxay kordhisaa waxtarka qaybaha korantada sida rogaha matoorka sababtoo ah khasaaraha oo yaraada.QaadoCaqli lehGenie tusaale ahaan hoos. Under madal danab isku mid ah iyo asal ahaan iska caabin wadada isku mid ah(ku dhawaad wax farqi ah uma laha miisaanka/qaabka/ ballaca taayirka),dhamaantood waa matoorada Virui. Marka la barbar dhigo rogayaasha IGBT, waxtarka guud ee beddelayaasha SiC ayaa la hagaajiyay ilaa 3%.Fiiro gaar ah: Horumarka dhabta ah ee hufnaanta beddelka ayaa sidoo kale la xidhiidha awoodaha naqshadaynta qalabka iyo horumarinta software ee shirkad kasta.
Alaabooyinka hore ee SiC waxaa xadiday habka kobaca waferka ee SiC iyo awoodaha farsamaynta jajabka, iyo awooda qaadida hal-chip ee hadda ee SiC MOSFETs aad ayay uga hoosaysay ta Si IGBTs.
2016, koox cilmi baaris ah oo ku sugan Japan ayaa ku dhawaaqday horumarka guusha leh ee rogaha cufnaanta sare ee awoodda iyadoo la adeegsanayo aaladaha SiC, ka dibna lagu daabacay natiijooyinka (Macaamilada Injineerada Korontada iyo Elektrooniga ee Machadka Injineerada Korontada ee Japan)IEEJ[3].Inverter-ku wuxuu lahaa wax soo saarka ugu badnaan 35kW wakhtigaas.
Sannadka 2021, iyadoo horumarka tignoolajiyada sannadba sanadka ka dambeeya, awoodda hadda jirta ee SiC MOSFET-yada wax soo saarka badan leh ee korontadu ay tahay 1200V ay horumartay, waxaana la arkay alaab la qabsan karta awood ka badan 200kW.
Marxaladan, tignoolajiyadani waxay bilaabatay in lagu dabaqo gawaarida dhabta ah.
Dhanka kale, waxqabadka aaladaha korantada korantada ee elektiroonigga ah ayaa u muuqda mid ku habboon.Aaladaha korontada ee SiC waxay leeyihiin waxtar ka sarreeya IGBTs, waxayna la jaan qaadi karaan awoodda korantada(1200V) eemadal 800V ah, oo ay ku horumareen awood koronto oo ka badan 200kW sanadihii ugu dambeeyay;
Dhanka kale, 800V faa'iidooyin madal koronto ah ayaa la arki karaa.Laba-laabashada danabku waxay keenaysaa xadka sare ee awoodda dallaca ee gaadhiga oo dhan mid ka sarreeya, luminta naxaasta ee nidaamka ayaa hooseeya, cufnaanta korantada ee matoorka ayaa ka sarreeya.(dabeecad ahaan, qulqulka iyo awoodda matoorka cabbirka la mid ah ayaa sarreeya);
Midda saddexaad waa in la kordhiyo kacdoonka suuqa tamarta cusub.Raacitaanka baaxadda safarka sare iyo buuxinta tamarta degdegga ah ee dhinaca macaamiisha, dhinaca ganacsigu wuxuu jecel yahay inuu sameeyo farqiga u dhexeeya tamarta tamarta ee suuqa tamarta cusub;
Qodobbada kor ku xusan ayaa ugu dambeyntii keenay sahaminta baaxadda weyn iyo adeegsiga tamarta cusub ee 800V aaladaha korantada sare ee labadii sano ee la soo dhaafay.Hadda liiska 800V moodooyinka madal waxaa ka mid ah Xiaopeng G9,PorscheTaycaniyo wixi la mida.
Intaa waxaa dheer, SAIC, Krypton,Lotusku haboonGaariga Tianjiiyo shirkadaha kale ee baabuurta sidoo kale waxay leeyihiin moodooyinka 800V ee la xidhiidha oo diyaar u ah in lagu soo bandhigo suuqa.
03.Waa maxay faa'iidooyinka dareenka leh ee nidaamka 800V hadda keeni karaa?
Nidaamka 800V aragti ahaan wuxuu qori karaa faa'iidooyin badan. Waxaan filayaa in faa'iidooyinka ugu dareen ee macaamiisha hadda jira ay u badan yihiin labadan soo socda.
Marka hore, nolosha batteriga ayaa dheer oo adag, taas oo ah faa'iidada ugu dareen.
Heerka isticmaalka korantada ee 100 kiiloomitir ee hoos yimaada xaaladaha hawlgalka CLTC, faa'iidooyinka uu keenay nidaamka 800V(sawirka hoose wuxuu muujinayaa isbarbardhigga u dhexeeya Xiaopeng G9 iyoBMWiX3, G9 waa ka culus yahay, jirku waa ka ballaaran yahay, iyotaayirradaway ka sii ballaadhan yihiin, kuwaas oo dhammaantood ah arrimo aan fiicnayn isticmaalka tamarta), qiyaasaha muxaafidka ah Waxaa jira koror 5% ah.
Xawaaraha sare, hagaajinta isticmaalka tamarta ee nidaamka 800V ayaa la sheegay inay aad u caddahay.
Intii lagu guda jiray furitaanka Xiaopeng G9, soosaarayaashu waxay si ula kac ah u hageen warbaahinta si ay u qabtaan tijaabooyinka nolosha batteriga xawaaraha sare leh. Warbaahino badan ayaa sheegay in 800V Xiaopeng G9 uu gaadhay heerka nolosha batteriga xawaare sare leh (nolosha batteriga xawaaraha sare / CLTC nolosha batteriga * 100%).
Saamaynta tamarta-badbaadinta dhabta ah waxay u baahan tahay xaqiijin dheeraad ah oo laga helo suuqa dabagalka.
Midda labaad waa in la siiyo ciyaar buuxda si ay u awoodaan tuusmada dallacaadda jira.
Moodooyinka 400V, marka ay wajahayaan 120kW, 180kW xirmooyinka dallacaadda, xawaaraha dallacadu waa isku mid. (Xogta imtixaanku waxay ka timid Chedi)Module-kordhinta DC-ga ee loo isticmaalo qaabka 800V wuxuu si toos ah u dalacayaa raso ku dallaca korantada yar ee hadda jira.(200kW/750V/250A)taas oo aan ku xaddidnayn korontadu awoodda buuxda ee 750V/250A.
Fiiro gaar ah: Korantada dhabta ah ee buuxda ee Xpeng G9 waxay ka hooseysaa 800V sababtoo ah tixgelin injineernimada.
Qaadashada tusaalaha tusaale ahaan, awoodda ku dallaca ee Xiaopeng G9 (800V platform)oo wata batari 100-degree ah oo isku mid ahwaa ku dhawaad 2 jeerTusmada ugu hooseysa ee JK001(400V madal).
04.Waa maxay dhibaatooyinka ku jira codsiga nidaamka 800V ee hadda?
Dhibaatada ugu weyn ee codsiga 800V ayaa weli ah mid aan kala sooc lahayn qiimaha.
Kharashkan waxa loo qaybiyaa laba qaybood: kharashka qaybta iyo kharashka horumarinta.
Aan ku bilowno qiimaha qaybaha.
Qalab koronto oo sarreeya waa qaali waxaana loo isticmaalaa tiro badan.Naqshadaynta guud ahaan 1200-voltage qalabka korantada sare ee leh qaab dhismeedka 800V oo buuxa ayaa isticmaala in ka badan30, iyo ugu yaraan 12SiC ee moodooyinka laba-motoor.
Laga bilaabo Sebtembar 2021, qiimaha tafaariiqda ee 100-A SiC MOSFETs (650 V iyo 1,200 V) waa ku dhawaad 3 jeerSicirka u dhigma Si IGBT.[4]
Laga bilaabo Oktoobar 11, 2022, waxaan bartay in farqiga qiimaha tafaariiqda ee u dhexeeya labada Infineon IGBTs iyo SiC MOSFETs oo leh tilmaamo waxqabad la mid ah uu yahay ilaa 2.5 jeer.(Isha xogta Infineon website-ka rasmiga ah Oktoobar 11, 2022)
Iyada oo ku saleysan labada ilo xog ee kor ku xusan, waxaa asal ahaan loo tixgelin karaa in suuqa SiC ee hadda jira uu ku saabsan yahay 3 jeer farqiga qiimaha IGBT.
Midda labaad waa kharashka horumarinta.
Maaddaama inta badan qaybaha 800V ee la xidhiidha ay u baahan yihiin in dib loo habeeyo oo la xaqiijiyo, mugga imtixaanku wuu ka weyn yahay alaabta yaryar ee soo noqnoqda.
Qaar ka mid ah qalabka tijaabada ee 400V ma noqon doonaan kuwo ku haboon alaabta 800V, iyo qalab cusub oo tijaabo ah ayaa loo baahan yahay in la soo iibiyo.
Dufcaddii ugu horreysay ee OEM-yada loo isticmaalo 800V alaabada cusub waxay badanaa u baahan yihiin inay la wadaagaan kharashaadyo horumarineed oo tijaabo ah oo dheeraad ah alaab-qeybiyeyaasha.
Marxaladdan, OEM-yadu waxay dooran doonaan alaabada 800V alaab-qeybiyeyaal la aasaasay si taxaddar leh, iyo kharashyada horumarinta alaab-qeybiyeyaasha la aasaasay ayaa noqon doona mid aad u sarreeya.
Marka loo eego qiyaasta injineerka baabuurta OEM sanadka 2021, qiimaha gaadhi koronto saafi ah oo heerkiisu yahay 400kW oo leh naqshad 800V buuxa ah iyo nidaamka 400kW dual-motor wuxuu ka kordhin doonaa 400V ilaa 800V, kharashkuna wuu kordhi doonaa qiyaastii10,000-20,000 yuan.
Midda saddexaad waa waxqabadka qiimaha jaban ee nidaamka 800V.
Qaadashada macaamiil koronto saafi ah iyadoo la isticmaalayo tusin dallacaad guri ah tusaale ahaan, iyadoo loo qaadanayo kharashka ku dallaca 0.5 yuan/kWh iyo isticmaalka tamarta 20kWh/100km (isticmaalka tamarta caadiga ah ee safarka xawaaraha sare leh ee moodooyinka EV ee dhexdhexaadka ah iyo kuwa waaweyn), Qiimaha kor u kaca ee hadda ee nidaamka 800V waxa uu macmiilku isticmaali karaa 10-200,000 kiiloomitir.
Qiimaha tamarta ee lagu badbaadiyay hagaajinta hufnaanta ee meertada nolosha baabuurka (oo ku salaysan hagaajinta hufnaanta madal koronto-sare iyo SiC, qoraagu waxa uu qiyaas ahaan ku qiyaasay faa'iidada waxtarka ee 3-5%)ma dabooli karo kororka qiimaha baabuurta.
Waxa kale oo jira xaddidaadda suuqa ee moodooyinka 800V.
Faa'iidooyinka qalabka 800V ee dhaqaalaha maaha mid cad, sidaas darteed waxay ku habboon tahay moodooyinka heerka sare ee B +/C kuwaas oo leh raadinta kama dambaysta ah ee waxqabadka baabuurta oo aan dareen lahayn qiimaha hal baabuur.
Gaadhiga noocaan ah waxa uu leeyahay saami yar oo suuqa ah.
Marka loo eego burburka xogta Xiriirka Rakaabka, laga bilaabo Janaayo ilaa Agoosto 2022, marka loo eego falanqaynta fasalka qiimaha baabuurta tamarta cusub ee Shiinaha, mugga iibka ee 200,000-300,000 ayaa xisaabay 22%, iibka 300,000 ilaa 400,000 ayaa lagu xisaabtamay16%, iyo iibka in ka badan 400,000 ayaa lagu xisaabtamay4%.
Qaadashada qiimaha 300,000 ee baabuurta xuduud ahaan, muddada qiimaha 800V ee qaybaha aan si weyn loo dhimin, moodooyinka 800V waxay xisaabin karaan qiyaastii 20% saamiga suuqa..
Afar, silsiladda sahayda qaybaha 800V waa mid aan qaan-gaarin.
Codsiga nidaamka 800V wuxuu u baahan yahay dib u cusboonaysiinta qaybaha wareegga korantada sare ee asalka ah.Batariyada madal-sare ee korantada, korantada korantada, dabaysha, nidaamyada maaraynta kulaylka iyo qaybaha, inta badan Tire1 iyo Tire2 ayaa weli ku jira marxaladda horumarinta mana lahan wax khibrad ah codsiyada wax soo saarka ballaaran. Waxaa jira alaab-qeybiyeyaal yar oo OEM-yada ah, iyo alaabooyinka aadka u bislaaday ayaa u nugul inay soo baxaan arrimo lama filaan ah dartood. arrimaha wax soo saarka.
Shanaad, 800V suuqa dambe waa mid aan la ansixin.
Nidaamka 800V wuxuu adeegsadaa alaabooyin badan oo dhawaan la sameeyay (matoorka roga, jirka mootada, baytariga, daareeyaha + DCDC, xiriiriyaha korantada sare, qaboojiyaha korantada sare, iwm.), waxaana lagama maarmaan ah in la xaqiijiyo nadiifinta, masaafada gurguurta, dahaarka, EMC, kuleylka kuleylka, iwm.
Waqtigan xaadirka ah, wareegga horumarinta iyo xaqiijinta badeecada ee suuqa tamarta cusub ee gudaha waa mid gaaban (sida caadiga ah, wareegga horumarinta mashaariicda cusub ee ganacsiyada hore ee wadajirka ah waa 5-6 sano, iyo wareegga horumarinta hadda ee suuqa gudaha waa wax ka yar 3 sano). ).Isla mar ahaantaana, wakhtiga dhabta ah ee baaritaanka suuqa baabuurta ee alaabta 800V kuma filna, iyo suurtogalnimada iibka ka dib ayaa ah mid aad u sarreeya. .
Lixaad, qiimaha codsiga wax ku oolka ah ee nidaamka 800V ee ku dallaca degdega ah maaha mid sarreeya.
Marka shirkadaha baabuurta ay kor u qaadaan 250kW,480kW (800V)Awoodda sare ee xawaaraha sare leh, waxay caadi ahaan soo bandhigaan tirada magaalooyinka ay ku yaalaan meelaha lagu dallaco, iyagoo damacsan inay ku hagaan macaamiisha si ay ugu fekeraan inay ku raaxaysan karaan khibradan wakhti kasta ka dib markay iibsadaan baabuur, laakiin xaqiiqadu sidaas uma fiicna.
Waxaa jira saddex caqabadood oo waaweyn:
Xiaopeng G9 800V Buug-yaraha Kharashka Degdegga ah ee Korantada Sare
(1) 800V xirmooyinka dallacaadda ayaa lagu dari doonaa.
Waqtigan xaadirka ah, xirmooyinka dallacaadda DC ee aadka u badan ee suuqa ayaa taageeraya danab ugu badnaan 500V/750V iyo hadda xaddidan ee 250A, kaas oo aan siin karin ciyaar buuxdaAwoodda dallacaadda degdegga ah ee nidaamka 800V(300-400kW) .
(2) Waxaa jira caqabado ku saabsan awoodda ugu badan ee 800V xirmooyinka sare-u-qaadka ah.
Qaadashada Xiaopeng S4 supercharger (qabow cadaadis sarreeya)Tusaale ahaan, awoodda dallacaadda ugu badan waa 480kW/670A.Sababtoo ah xaddidaadda awoodda korantada, saldhigga bannaanka ayaa kaliya taageera ku dallacaadda hal-baabuur, kaas oo kicin kara awoodda ugu sarreysa ee noocyada 800V. Inta lagu jiro saacadaha ugu sarreeya, isku mar ku dallaca baabuurta badan waxay sababi doontaa leexinta tamarta.
Marka loo eego tusaale ahaan xirfadlayaasha tamarta korontada: dugsiyada leh in ka badan 3,000 oo arday oo ku yaal aagga xeebta bari waxay dalbanayaan awoodda 600kVA, taas oo taageeri karta 480kW 800V tusin sare leh oo ku salaysan qiyaasta 80% waxtarka.
(3) Kharashka maalgashiga ee 800V tusinnada la soo dalacday waa mid sarreeya.
Tani waxay ku lug leedahay Transformers, piles, kaydinta tamarta, iwm. Kharashka dhabta ah waxaa lagu qiyaasaa inuu ka badan yahay kan isweydaarsiga, iyo suurtagalnimada in la geeyo baaxad weyn.
800V supercharging waa keega kaliya ee lagu dallaci karo, markaa noocee ah qaabaynta xarunta dallacaadda ayaa wanaajin kara khibrada dallacaadda?
Beerta Dallacaadda Xawaaraha Sare ee Fasaxa 2022
05.Male-awaalka qaabaynta xarumaha dallacaadda mustaqbalka
Waqtigan xaadirka ah, dhammaan kaabayaasha dal-ku-dallaca ee gudaha, saamiga gaadhi-ilaa-tuul (oo ay ku jiraan tuunnada dadweynaha + tuunnada gaarka ah)ayaa weli ku jirta heerka qiyaastii 3:1(ku salaysan xogta 2021).
Kor u kaca iibka baabuurta tamarta cusub iyo fududaynta welwelka macaamiisha ee dallacaadda, waxaa lagama maarmaan ah in la kordhiyo saamiga-baabuur-kuul. Tilmaamo kala duwan oo ku saabsan xirmooyinka dallacaadda degdega ah iyo raasamaal-ku dallacaadda ayaa si macquul ah loo habayn karaa xaaladaha loo socdo iyo xaaladaha degdegga ah ee dallacaadda, si loo horumariyo khibradda dallacaadda. Si loo horumariyo, oo runtii isu dheelitiri karo culeyska sharoobada.
Midda kowaad waa dallacaadda goobta, dallacaadda iyada oo aan wakhti dheeraad ah la sugin:
(1) Goobaha baarkinka ee la deggan yahay: Tiro badan oo la wadaago oo nidaamsan oo lagu dallaco gaabis ah oo 7kW ah ayaa la dhisay, baabuurta saliidda ayaa la siiyaa mudnaanta si ay u dhigtaan meelaha baabuurta la dhigto ee aan tamar cusub ahayn, kuwaas oo dabooli kara baahida dadka deggan, iyo kharashka dhigista waa in yar oo hooseeya, iyo habka xakamaynta habsamida leh ayaa sidoo kale ka fogaan kara in uu dhaafo xadhkaha korantada ee gobolka. kartida.
(2) Goobaha dukaamaysiga/goobaha quruxda badan/ jardiinooyinka warshadaha/dhismaha xafiisyada/huteelada iyo meelaha kale ee baabuurta la dhigto: 20kW dallacaadda degdega ah waa la kabay, tiro badan oo 7kW ah ayaa la dhisay.Dhinaca horumarinta: kharash yar oo dallacaadda tartiib tartiib ah oo aan lahayn kharash balaadhin; Dhinaca macaamiisha: iska ilaali inaad ku dallacdo meel bannaan/baabuur dhaqaaqo ka dib markii dallacaadda degdega ah si buuxda loogu dallaco muddo gaaban gudaheed.
Midda labaad waa buuxinta tamarta degdegga ah, sida loo badbaadiyo guud ahaan wakhtiga isticmaalka tamarta:
(1) Aagga adeegga jidka degdega ah: ilaali tirada hadda ee dallacaadda degdegga ah, si adag u xaddid dallacaadda xadka sare (sida 90% -85% ee ugu sarreysa), oo hubi xawaaraha ku dallaca ee baabuurta wadista masaafo dheer.
(2) Kaalmaha shidaalka ee u dhow halka laga soo galo ee magaalooyinka waaweyn/magaalooyinka: waxay habeeyaan ku dallacaadda awoodda sare leh, oo si adag u xaddid dallacaadda xadka sare (sida 90%-85% marka ugu sarreysa), sida kaabista aagga adeegga xawaaraha sare leh, oo u dhow wadista fogaanta fog ee isticmaalayaasha tamarta cusub, iyada oo la iftiiminayo baahida ku dallaca dhulka ee magaalada/magaalada.Fiiro gaar ah: Sida caadiga ah, saldhigga gaaska dhulka waxaa lagu qalabeeyaa awood koronto oo 250kVA ah, taas oo qiyaas ahaan taageeri karta laba xabbo oo xajmi ah oo 100kW isku mar ah.
(3) Kaalinta shidaalka ee magaalada/Barkinta hawada-furan: habee ku dallacaadda awoodda sare leh si loo xaddido xadka sare ee dallacaadda.Waqtigan xaadirka ah, PetroChina waxay geyneysaa tas-hiilaad degdeg ah oo lagu dallaco / sarrifka tamarta cusub, waxaana la filayaa in kaalmaha shidaalka oo badan oo dheeraad ah ay ku qalabaysan doonaan xirmooyin degdeg ah mustaqbalka.
Fiiro gaar ah: Goobta juqraafiyeed ee saldhigga shidaalka / baarkinka hawada furan lafteedu waxay u dhowdahay wadada dhinaceeda iyo sifooyinka dhismuhu waa kuwo aad u muuqda, taas oo ku habboon in lagu dallaco macaamiisha si ay si dhakhso ah u helaan rasin oo ay uga baxaan goobta si degdeg ah.
06.Qor dhamaadka
Waqtigan xaadirka ah, nidaamka 800V ayaa wali la kulma dhibaatooyin badan oo xagga kharashka, tignoolajiyada iyo kaabayaasha. Dhibaatooyinkan ayaa ah habka kaliya ee hal-abuurka iyo horumarinta tignoolajiyada baabuurta tamarta cusub iyo soo celinta warshadaha. marxaladda.
Shirkadaha baabuurta ee Shiinaha, oo leh awooddooda codsi injineernimo oo degdeg ah oo hufan, ayaa laga yaabaa inay awoodaan inay ogaadaan tiro badan oo ah codsiyada degdega ah ee nidaamyada 800V, oo ay hormuud ka noqdaan hogaaminta isbeddelka tiknoolajiyada ee berrinka baabuurta tamarta cusub.
Macaamiisha Shiinaha ayaa sidoo kale noqon doona kuwa ugu horreeya ee ku raaxaysta khibradda tayada sare leh ee uu keenay horumarka tignoolajiyada.Hadda ma aha sidii waagii baabuurta shidaalka, marka macaamiisha waddanku ay ka iibsadaan moodallo duug ah shirkado baabuur oo caalami ah, tignoolajiyada hore ama tignoolajiyada la tuuray.
