Kutheni ibhetri yeblade ye-BYD ngoku iyinto eshushu?
"Ibhetri yeblade" yeBYD, ebixoxwa kakhulu kweli shishini ixesha elide, ekugqibeleni ityhile inkangeleko yayo yokwenyani.
Mhlawumbi kutshanje abantu abaninzi bebesiva igama elithi "blade battery", kodwa mhlawumbi bengaqhelananga nalo, ngoko ke namhlanje siza kulichaza ngokweenkcukacha eli gama.
Ngubani owaqala ukuphakamisa ibhetri yeblade
USihlalo we-BYD uWang Chuanfu ubhengeze ukuba i-BYD "blade battery" (isizukulwana esitsha seebhetri ze-lithium iron phosphate) iza kuqala ukuveliswa ngobuninzi kwifektri yaseChongqing ngoMatshi kulo nyaka, kwaye ngoJuni idweliswe kwiHan EV The okokuqala ukuyithwala. Emva koko i-BYD yaphinda yafika kwiindaba eziphambili kwiimoto nakwiindawo zezimali zamaqonga eendaba amakhulu.
Kutheni ibhetri yeBlade
Ibhetri yeblade ikhutshwe yi-BYD nge-29 kaMatshi 2020. Igama layo elipheleleyo yibhetri ye-lithium iron phosphate yohlobo lweblade, eyaziwa ngokuba yi-"super lithium iron phosphate battery". Ibhetri isebenzisa ubuchwepheshe be-lithium iron phosphate, kwaye iza kuqala ixhotyiswe ngemodeli ye-BYD "Han".
Enyanisweni, "ibhetri yeblade" sisizukulwana esitsha sebhetri ye-lithium iron phosphate esandula ukukhutshwa yi-BYD, eneneni, i-BYD igxile kuphuhliso lwe-"super lithium iron phosphate" ngeminyaka emininzi yophando, mhlawumbi umenzi unethemba lokuba ngegama elibukhali nelingokomfuziselo, ukufumana ingqalelo engakumbi kunye nempembelelo.
Umzobo wesakhiwo sebhetri yeblade
Xa kuthelekiswa nebhetri ye-lithium iron phosphate yangaphambili ye-BYD, isitshixo "sebhetri yeblade" senziwe ngaphandle kwemodyuli, sidityaniswe ngokuthe ngqo kwiphakheji yebhetri (oko kukuthi iteknoloji ye-CTP), ngaloo ndlela siphucula kakhulu ukusebenza kakuhle kokuhlanganiswa.
Kodwa eneneni, i-BYD ayisiye umenzi wokuqala ukusebenzisa itekhnoloji ye-CPT. Njengomenzi omkhulu webhetri yamandla efakiweyo ehlabathini, i-Ningde Times yasebenzisa itekhnoloji ye-CPT ngaphambi kwe-BYD. ngoSeptemba 2019, i-Ningde Times yabonisa obu buchwepheshe kwiFrankfurt Motor Show.
I-Tesla, i-Ningde Times, i-BYD kunye ne-Hive Energy, baqalile ukuphuhlisa kwaye babhengeze ukuba baza kuvelisa ngobuninzi iimveliso ezinxulumene ne-CTP, kwaye iipakethe zebhetri zamandla ezingenamandla ziqala ukuba yindlela yetekhnoloji eqhelekileyo.
Iphakheji yebhetri ye-ternary lithium yendabuko
Le module ibizwa ngokuba yinxalenye yamacandelo afanelekileyo abumba imodule, ikwaqondwa njengengcamango yokuhlanganiswa kwamalungu. Kule ndawo yebhetri, inani leeseli, imigca eqhubayo, iiyunithi zokuthatha iisampulu kunye nezinye izinto ezifunekayo zenkxaso yesakhiwo zidityaniswe kunye ukwenza imodule, ekwabizwa ngokuba yimodule.
Ibhetri yeNingde Times CPT
I-CPT (iseli ukuya kwiphakheji) kukuhlanganiswa ngokuthe ngqo kweeseli kwiphakheji yebhetri. Ngenxa yokususwa kwekhonkco lokuhlanganisa imodyuli yebhetri, inani leenxalenye zephakheji yebhetri lincitshiswa ngama-40%, izinga lokusetyenziswa kwevolumu yephakheji yebhetri ye-CTP linyuswa ngama-15%-20%, kwaye ukusebenza kakuhle kwemveliso kunyuswa ngama-50%, nto leyo enciphisa kakhulu iindleko zokuvelisa ibhetri yamandla.
Kuthekani ngexabiso lebhetri yeblade
Ukuthetha ngexabiso, ibhetri ye-lithium iron phosphate ngokwayo ayisebenzisi zisinyithi ezinqabileyo ezifana ne-cobalt, ixabiso liyinzuzo yayo. Kuyaqondakala ukuba imakethi yeeseli zebhetri ye-lithium ye-ternary ka-2019 inikezela malunga ne-900 RMB / kW-h, ngelixa isibonelelo seeseli zebhetri ye-lithium iron phosphate malunga ne-700 RMB / kW-h, kwixesha elizayo kuya kudweliswa iHan umzekelo, uluhlu lwayo lunokufikelela kwi-605km, iphakheji yebhetri iqikelelwa ukuba ingaphezulu kwe-80kW-h, ukusetyenziswa kweebhetri ze-lithium iron phosphate kunokuba ngaphantsi kwe-16,000 RMB (2355.3 USD) engabizi kakhulu. Khawuthelekelele esinye isithuthi samandla esitsha sasekhaya esinexabiso elifanayo kunye noluhlu njenge-BYD Han, iphakheji yebhetri yodwa inenzuzo yexabiso le-20,000 RMB (2944.16 USD), ngoko ke kucacile ukuba yeyiphi enamandla okanye ebuthathaka.
Kwixesha elizayo, i-BYD Han EV ineenguqulelo ezimbini: uhlobo lwe-single-motor enamandla angama-163kW, i-330N-m peak torque kunye noluhlu lwe-605km NEDC; uhlobo lwe-dual-motor olunamandla angama-200kW, i-350N-m maximum torque kunye noluhlu lwe-550km NEDC.
Ngomhla we-12 ku-Agasti, kuxelwe ukuba ibhetri yeblade ye-BYD ithunyelwe kwiGigafactory Berlin yaseTesla, ekulindeleke ukuba ixhotyiswe ngebhetri yeemoto zeTesla ezingaphandle komgca ekupheleni kuka-Agasti ukuya ekuqaleni kukaSeptemba kwangoko, ngelixa i-gigafactory yaseTesla yaseShanghai ingenazicwangciso zokusebenzisa iibhetri ze-BYD.
I-teslamag.de iqinisekisile ubunyani beendaba. I-Model Y eneebhetri ze-BYD kuthiwa ifumene imvume yohlobo oluvela kwi-EU, eyanikwa yi-Dutch RDW (uMnyango wezoThutho waseDatshi) ngoJulayi 1, 2022. Kolu xwebhu, i-Model Y entsha ibizwa ngokuba yi-Type 005, enomthamo webhetri we-55 kWh kunye nomgama we-440 km.
Zithini iingenelo zeebhetri zeblade
Ikhuselekile ngakumbi:Kwiminyaka yakutshanje, iingozi zokhuseleko lwezithuthi zombane bezixhaphakile, kwaye uninzi lwazo lubangelwa kukutshisa kweebhetri. "Ibhetri yeblade" kunokuthiwa yeyona ikhuselekileyo kwimarike. Ngokwezilingo ezipapashwe yiBYD malunga novavanyo lokungena kwezipikili zebhetri, sinokubona ukuba "ibhetri yeblade" emva kokungena, ubushushu bebhetri bunokugcinwa phakathi kwama-30-60 ℃, oku kungenxa yokuba isekethe yebhetri yeblade inde, indawo enkulu yomphezulu kwaye isasazeka ngokukhawuleza. U-Ouyang Minggao, ingcali yezemfundo ye-Chinese Academy of Sciences, ubonise ukuba uyilo lwebhetri yeblade lwenza ukuba ivelise ubushushu obuncinci kwaye ichithe ubushushu ngokukhawuleza xa i-short-circuit, kwaye uvavanye ukusebenza kwayo "kuvavanyo lokungena kwezipikili" njengogqwesileyo.
Uxinano lwamandla aphezulu:Xa kuthelekiswa neebhetri ze-ternary lithium, iibhetri ze-lithium iron phosphate zikhuselekile kwaye zinobomi obude bomjikelo, kodwa ngaphambili kwibhetri amandla oxinano aye acinezelwa intloko. Ngoku ibhetri yeblade wh/kg uxinano kunesizukulwana sangaphambili seebhetri, nangona ukwanda kwe-9% kumandla e-wh/l, kodwa ukwanda ukuya kuthi ga kwi-50%. Oko kukuthi, amandla ebhetri "yeblade" anokwandiswa nge-50%.
Ubomi bebhetri obude:Ngokwezilingo, ubomi bomjikelo wokutshaja kwebhetri yeblade budlula amaxesha angama-4500, oko kukuthi ukubola kwebhetri kungaphantsi kwama-20% emva kokutshaja amaxesha angama-4500, ubomi bungaphezulu kwamaxesha ama-3 ebhetri ye-lithium ye-ternary, kwaye ubomi obulinganayo bemayile yebhetri yeblade budlula i-1.2 yezigidi zeekhilomitha.
Ungenza njani umsebenzi olungileyo kumphezulu weqokobhe eliphambili, ipleyiti yokupholisa, isigqubuthelo esingaphezulu nesisezantsi, itreyi, i-baffle kunye nezinye izinto ukuze kufezekiswe iimfuno zokhuseleko zokukhusela, ukuthintela ubushushu, ukuthintela ilangatye, ukungatshi kwaye kuhlangatyezwane neemfuno zemveliso ezenzekelayo? Ngumceli mngeni omkhulu kunye noxanduva lomzi-mveliso wokufaka iipayinti kwixesha elitsha.
