Bishii Sebtembar 13, Wasaaradda Warshadaha iyo Tiknoolajiyada Warfaafinta ayaa ku dhawaaqday in GB/T 20234.1-2023 "Xiriirka Aaladaha loogu dallaco Gaadiidka Korontada Qaybta 1: Ujeedada Guud" waxaa dhawaan soo jeediyay Wasaaradda Warshadaha iyo Tignoolajiyada Warfaafinta iyo iyadoo hoos timaad awoodda Guddiga Farsamada Qaranka ee Habaynta Baabuurta. Shuruudaha" iyo GB/T 20234.3-2023 "Isku xidhka Aaladaha loogu dallaco Dhaqaale ee Baabuurta Korontada Qaybta 3: Interface Charging DC" laba heer qaran oo lagu taliyay ayaa si rasmi ah loo sii daayay.
Iyadoo la raacayo xalalka farsamada ee dalkeyga hadda ee dallacaadda DC-ga iyo hubinta iswaafajinta caalamiga ah ee is-dhexgalka cusub iyo kuwii hore, heerka cusub wuxuu kordhiyaa dallacaadda ugu badan ee hadda laga bilaabo 250 amps ilaa 800 amps iyo awoodda ku dallaca ilaa800 kw, oo ku dara qaboojin firfircoon, la socodka heerkulka iyo sifooyinka kale ee la xidhiidha. Shuruudaha farsamada, hagaajinta iyo hagaajinta hababka tijaabada ee guryaha farsamada, qalabka qufulka, nolosha adeegga, iwm.
Wasaaradda Warshadaha iyo Tignoolajiyada ayaa tilmaamtay in qiimaha dallacadu ay saldhig u yihiin hubinta isku xidhka gaadiidka korontada ku shaqeeya iyo goobaha lagu dallaco iyo sidoo kale dallacado sugan oo la isku halayn karo. Sanadihii la soo dhaafay, iyadoo tirada wadista baabuurta korontadu ay kordheyso iyo heerka ku dallaca baytariyada korantada uu kordho, macaamiishu waxay leeyihiin baahi xoog leh oo sii kordheysa oo baabuurta si ay si dhakhso ah u buuxiyaan tamarta korontada. Tignoolajiyada cusub, qaababka cusub ee ganacsiga, iyo dalabaadka cusub ee ay matalaan "dallacaadda awoodda sare leh ee DC" ayaa sii socota soo ifbaxa, waxay noqotay heshiis guud oo warshadaha si loo dedejiyo dib u eegis iyo hagaajinta heerarka asalka ah ee la xidhiidha isdhaafsiga lacag bixinta.
Marka loo eego horumarinta tikniyoolajiyadda ku dallaca baabuurta korantada iyo baahida loo qabo dib-u-kicinta degdegga ah, Wasaaradda Warshadaha iyo Teknolojiyadda Warfaafinta waxay abaabushay Guddiga Farsamada ee Halbeegga Baabuurta Qaranka si ay u dhammaystiraan dib-u-eegista laba heerar qaran oo lagu taliyey, gaaritaanka casriyeyn cusub oo ah nooca asalka ah ee 2015 ee nidaamka heerka qaran (oo loo yaqaan '2015 +' standard), kaas oo u sahlaya la qabsiga deegaanka iyo hagaajinta isku xirnaanta deegaanka wakhtiga buuxinta baahiyaha dhabta ah ee ku dallacaadda awood-yar ee DC.
Talaabada xigta, Wasaaradda Warshadaha iyo Tignoolajiyada Macluumaadka waxay qabanqaabin doontaa cutubyo khuseeya si ay u fuliyaan xayeysiin qotodheer, dhiirigelin iyo hirgelinta labada heer qaran, kor u qaadida iyo adeegsiga awoodda sare ee awoodda DC iyo tignoolajiyada kale, iyo abuurista jawi horumarineed oo tayo sare leh oo loogu talagalay warshadaha baabuurta tamarta cusub iyo warshadaha xarumaha lacag-bixinta. Deegaan wanaagsan. Ku dallacaadda qunyar socodka ah waxay had iyo jeer ahayd barta xanuunka udub dhexaadka u ah warshadaha baabuurta korontada.
Sida lagu sheegay warbixin ay soo saartay Soochow Securities, celceliska celceliska dallacaadda aragtida ee moodooyinka iibka kulul ee taageeraya ku dallaca degdegga ah ee 2021 waa qiyaastii 1C (C waxay ka dhigan tahay heerka ku dallaca nidaamka batteriga. In shuruudaha layman, ku dallaca 1C si buuxda u dallaci karaan nidaamka batteriga 60 daqiiqo) , taas oo ah, waxay qaadataa qiyaastii 30-daqiiqo nolosha SOC si ay u gaarto 30% batteriga, 219km (Heerka NEDC).
Ficil ahaan, badi baabuurta korantada saafiga ah waxay u baahan yihiin 40-50 daqiiqo oo lacag ah si ay u gaaraan SOC 30% -80% waxayna socon karaan ilaa 150-200km. Haddii wakhtiga lagu galo lagana baxo saldhiga dallacaadda (ilaa 10 daqiiqo) lagu daro, gaadhi koronto saafi ah oo qaadata ku dhawaad 1 saac in lagu dallaco waxa uu kaliya ku wadi karaa wadada in ka badan 1 saac.
Horumarinta iyo adeegsiga tignoolajiyada sida ku dallacaadda awoodda sare leh ee DC waxay u baahan doontaa cusboonaysiinta shabakada dallacaadda mustaqbalka. Wasaaradda Sayniska iyo Tignoolajiyada ayaa hore u soo bandhigtay in dalkaygu uu hadda dhisay shabakad tas-hiilaad lacag-bixineed oo leh tirada ugu badan ee qalabka lagu dallaco, halka ugu badanna uu dabooli karo. Inta badan tas-hiilaadka cusub ee dallacaadda dadweynaha ayaa u badan qalabka degdegga ah ee DC ee leh 120kW ama ka badan.7kW AC oo xajmi gaabis ahwaxay noqdeen halbeeg ay ku leeyihiin ganacsiga gaarka loo leeyahay. Codsiga ku dallacaadda degdegga ah ee DC ayaa asal ahaan caan ka noqday goobta baabuurta gaarka ah. Tas-hiilaadka dallacaadda dadweynuhu waxay leeyihiin isku-xidhka dariiqa daruuriga ah ee la socodka wakhtiga dhabta ah. Awoodaha, helitaanka APP-da iyo lacag-bixinta khadka tooska ah ayaa si weyn loo isticmaalay, iyo tignoolajiyada cusub sida ku dallacaadda awoodda sare leh, ku dallacaadda awoodda yar ee DC, isku xirka dallacaadda tooska ah iyo dallacaadda nidaamsan ayaa si tartiib tartiib ah loo warshadeeyay.
Mustaqbalka, Wasaaradda Sayniska iyo Tiknoolajiyada waxay diiradda saari doontaa tignoolajiyada muhiimka ah iyo qalabka loogu talagalay dallacaadda iskaashiga hufan iyo isdhaafsiga, sida teknoolojiyadda muhiimka ah ee isku xirka daruuraha gawaarida, dallacaadda hababka qorsheynta xarunta iyo tignoolajiyada maamulka lacag bixinta, tignoolajiyada muhiimka ah ee ku dallacaadda wireless-ka ee awoodda sare leh, iyo teknoolojiyadda muhiimka ah ee beddelka degdegga ah ee baytariyada korontada. Xoojinta cilmi baarista sayniska iyo tignoolajiyada.
Dhanka kale,ku dallacaadda awoodda sare ee DCdhigaya shuruudaha sare ee waxqabadka baytariyada korontada, qaybaha muhiimka ah ee baabuurta korontada.
Marka loo eego falanqaynta Soochow Securities, ugu horreyntii, kordhinta heerka dallacaadda batteriga waa lid ku ah mabda'a kordhinta cufnaanta tamarta, sababtoo ah heerka sare wuxuu u baahan yahay qaybo yaryar oo ka mid ah qalabka elektiroonigga ah ee wanaagsan iyo kuwa taban ee batteriga, iyo cufnaanta tamarta sare waxay u baahan tahay qaybo waaweyn oo ah qalabka elektiroonigga ah ee taban.
Marka labaad, ku dallaca heerka sare ee xaalad awood sare leh waxay keenaysaa falcelin dhinaca lithium-ka ah oo aad u daran iyo saamaynta kulaylka batteriga, taasoo keentay hoos u dhaca badbaadada batteriga.
Waxaa ka mid ah, walxaha korantada taban ee baytarigu waa qodobka ugu weyn ee xaddidaya ku dallacaadda degdegga ah. Tani waa sababta oo ah graphite electrode taban wuxuu ka samaysan yahay xaashiyo graphene, iyo ions lithium waxay galaan xaashida geesaha. Sidaa darteed, inta lagu jiro habka degdegga ah ee dallacaadda, electrode negative si degdeg ah u gaaro xadka ay awood u ah inuu nuugo ions, iyo lithium ions bilaabay in ay sameeyaan lithium bir adag on sare ee qaybaha graphite, taas oo ah, jiilka Lithium falcelinta dhinaca. Roobka lithium-ku waxa uu yarayn doonaa aagga waxtarka leh ee korantada taban ee ion lithium in la dhex dhigo. Dhinaca kale, waxay yaraynaysaa awoodda batteriga, waxay kordhisaa caabbinta gudaha, waxayna yaraynaysaa cimriga. Dhanka kale, kirismaska interface ayaa koraan oo dalooliya kala-soocida, saameynaya badbaadada.
Professor Wu Ningning iyo kuwa kale oo ka socda Shanghai Handwe Industry Co., Ltd. ayaa sidoo kale hore u qoray in si loo hagaajiyo awoodda degdegga ah ee awoodda baytariyada korontada, ay lagama maarmaan tahay in la kordhiyo xawaaraha socdaalka ee ions lithium ee walxaha batteriga ah iyo in la dedejiyo dhejinta lithium ions ee walxaha anode. Hagaajinta habdhaqanka ionic ee elektrolytka, dooro kala-soocida degdega ah, wanaaji socodka ionic iyo elektiroonigga ee korantada, oo dooro istaraatiijiyad dallacaad ku habboon.
Si kastaba ha ahaatee, waxa macaamiishu ay sugi karaan waa tan iyo sannadkii hore, shirkadaha baytariyada gudaha waxay bilaabeen inay horumariyaan oo ay geeyaan baytariyada degdega ah. Bishii Agoosto ee sanadkan, hogaanka CATL ayaa sii daayay 4C Shenxing batteriga superchargeable oo ku salaysan nidaamka fosfateed lithium birta wanaagsan (4C macnaheedu waa in batteriga si buuxda loo dallaci karo rubuc saac ah), kaas oo gaari kara "10 daqiiqo oo dallac ah iyo kala duwan oo ah 400 kw" Xawaaraha sare u qaadista xawaaraha. Heerkulka caadiga ah, batteriga waxaa lagu dalaci karaa 80% SOC 10 daqiiqo gudahood. Isla mar ahaantaana, CATL waxay isticmaashaa tignoolajiyada xakamaynta heerkulka unugga ee nidaamka nidaamka, kaas oo si dhakhso ah u kululayn kara heerkulka hawlgalka ugu fiican ee jawiga heerkulka hooseeya. Xataa jawiga heerkulka hooseeya ee -10 ° C, waxaa lagu dallaci karaa 80% 30 daqiiqo gudaheed, iyo xitaa heerkulka hooseeya ee xawaaraha Eber-boqol-boqol-xawaaraha ma qudhmo gobolka korontada.
Marka loo eego CATL, baytariyada Shenxing supercharged waxaa la soo saari doonaa tiro badan sanadkan gudihiisa waxayna noqon doonaan kuwii ugu horreeyay ee loo isticmaalo moodooyinka Avita.
