Intshayelelo:
Ukutshaja kwemizuzu emi-5 kumgama weekhilomitha ezingama-400! Ngomhla we-17 kweyoKwindla, i-BYD ikhuphe inkqubo yayo "yokutshaja nge-megawatt flash", eya kwenza ukuba izithuthi zombane zikwazi ukutshaja ngokukhawuleza njengokugcwalisa ipetroli.
Nangona kunjalo, ukuze kufezekiswe injongo "yeoyile nombane ngesantya esifanayo", i-BYD ibonakala ngathi ifikelele kumda webhetri yayo ye-lithium iron phosphate. Nangona ubuninzi bamandla bezinto ze-lithium iron phosphate ngokwayo busondela kumda wayo wethiyori, i-BYD isaqhubeka nokunyusa uyilo lwemveliso kunye nokuphuculwa kwetekhnoloji kakhulu.
Dlala ngokugqithisileyo! I-10C lithium iron phosphate
Okokuqala, ngokweenkcukacha ezikhutshwe kwinkomfa yabezindaba ye-BYD, iteknoloji yokutshaja nge-flash ye-BYD isebenzisa imveliso ebizwa ngokuba yi-"flash charging blade battery", eseluhlobo lwebhetri ye-lithium iron phosphate.
Oku akupheleli nje ekupheliseni ulawulo lweebhetri ze-lithium ezikumgangatho ophezulu ezifana neebhetri ze-nickel ternary eziphezulu kwimarike yokutshaja ngokukhawuleza, kodwa kukwavumela i-BYD ukuba iphinde inyuse ukusebenza kwe-lithium iron phosphate, okuvumela i-BYD ukuba iqhubeke nexabiso layo kwimarike kwindlela yetekhnoloji yeebhetri ze-lithium iron phosphate.
Ngokwedatha ekhutshwe yi-BYD, i-BYD ifikelele kwinqanaba eliphezulu lokutshaja eliyi-1 megawatt (1000 kW) kwezinye iimodeli ezifana neHan L kunye neTang L, kwaye ukutshaja okukhawulezayo kwemizuzu emi-5 kunokongeza kumgama weekhilomitha ezingama-400. Ibhetri yayo yokutshaja okukhanyayo ifikelele kwinqanaba lokutshaja eliyi-10C.
Ngowuphi lo mbono? Ngokwemigaqo yesayensi, okwangoku kuyaziwa kwishishini ukuba uxinano lwamandla eebhetri ze-lithium iron phosphate lusondele kumda wethiyori. Ngokwesiqhelo, ukuqinisekisa uxinano lwamandla aphezulu, abavelisi baya kuncama ukusebenza kwabo kokutshaja kunye nokukhupha. Ngokubanzi, ukukhupha kwe-3-5C kuthathwa njengelona zinga lifanelekileyo lokukhupha iibhetri ze-lithium iron phosphate.
Nangona kunjalo, ngeli xesha i-BYD yonyuse izinga lokukhupha i-lithium iron phosphate ukuya kwi-10C, nto leyo engathethi nje kuphela ukuba umsinga uphantse waphindaphindeka kabini, kodwa ikwathetha nokuba ukumelana kwangaphakathi kunye nobunzima bokulawula ubushushu buphindaphindeke kabini.
I-BYD ithi ngokusekelwe kwi-blade, "ibhetri yokutshaja nge-flash" ye-BYD iphucula ulwakhiwo lwe-electrode yebhetri ye-blade, inciphisa ukumelana kokufuduka kwee-ion ze-lithium nge-50%, ngaloo ndlela ifikelela kwisantya sokutshaja esingaphezulu kwe-10C okokuqala.
Kwizinto ze-electrode ezilungileyo, i-BYD isebenzisa izixhobo ze-lithium iron phosphate zesizukulwana sesine ezicocekileyo kakhulu, ezixineneyo kakhulu, kunye nezixineneyo kakhulu, kunye neenkqubo zokutyumza ze-nanoscale, izongezo ezikhethekileyo zefomula, kunye neenkqubo ze-calcination zobushushu obuphezulu. Ulwakhiwo lwekristale yangaphakathi olugqibeleleyo kunye nendlela emfutshane yokusasazwa kwee-ion ze-lithium yonyusa izinga lokufuduka kwee-ion ze-lithium, ngaloo ndlela kunciphisa ukumelana kwangaphakathi kwebhetri kunye nokuphucula ukusebenza kwesantya sokukhupha.
Ukongeza, ngokwemigaqo yokukhetha ii-electrode ezingalunganga kunye nee-electrolytes, kuyimfuneko ukukhetha eyona ilungileyo kweyona ilungileyo. Ukusetyenziswa kwe-graphite yokwenziwa enommandla ophezulu womphezulu kunye nokongezwa kwee-electrolytes ze-PEO (polyethylene oxide) ezisebenzayo nazo ziye zaba ziimeko eziyimfuneko zokuxhasa iibhetri ze-10C lithium iron phosphate.
Ngamafutshane, ukuze kufezekiswe impumelelo yokusebenza, i-BYD ayichithi mali. Kwinkomfa yabezindaba, ixabiso le-BYD Han L EV elinebhetri "yokutshaja nge-flash" lifikelele kwi-270000-350000 yuan, eliphantse libe yi-70000 yuan ephezulu kunexabiso le-2025 EV intelligent driving version (701KM Honor model).
Ingakanani ixesha lokuphila kunye nokhuseleko lweebhetri zokutshaja nge-flash?
Kakade ke, kubuchwepheshe obuphezulu, ukubiza kakhulu akuyongxaki. Wonke umntu usaxhalabile ngomgangatho kunye nokhuseleko lwemveliso. Ngokuphathelele oku, uLian Yubo, uSekela Mongameli oPhetheyo weBYD Group, uthe iibhetri zokutshaja ngeflash zinokuphila ixesha elide nangona zitshajwa ngamaxabiso aphezulu kakhulu, kunye nokonyuka kwama-35% kubomi bomjikelo webhetri.
Kunokuthiwa impendulo yeBYD ngeli xesha ilungile kwaye igcwele izakhono, ubuncinane ayikhanyeli impembelelo yokutshaja kakhulu kubomi bebhetri.
Kuba ngokwesiseko, ukutshaja nokukhupha ngokukhawuleza kuya kuba nemiphumo engenakuguqulwa kwisakhiwo sebhetri. Okukhona isantya sokutshaja nokukhupha sikhawuleza, kokukhona impembelelo enkulu kubomi bomjikelo webhetri. Ngokuphathelele ukutshaja kakhulu, ukusetyenziswa ixesha elide kudla ngokunciphisa ubomi bebhetri ngama-20% ukuya kuma-30%. Ke ngoko, uninzi lwabavelisi bacebisa ukutshaja kakhulu njengendlela yokutshaja engxamisekileyo.
Abanye abavelisi baya kungenisa ukutshaja kakhulu ngokusekelwe ekuphuculeni ubomi bomjikelo webhetri ngokwayo. Ukuncipha kobomi bebhetri okubangelwa kukutshaja kakhulu kuncitshiswa kukwanda kobomi bebhetri ngumvelisi, ekugqibeleni kuvumela yonke imveliso ukuba iqhubeke nokutshaja kakuhle kunye nokusebenza kakuhle ngexesha layo elilindelekileyo.
Ukongeza, ukuze kufezekiswe "ukutshaja nge-flash", i-BYD ikwaqalise uthotho lohlaziyo lwenkqubo malunga nokusilela kweebhetri ze-lithium iron phosphate kunye nenkqubo yonke yokubonelela ngombane.
Ukuze kulungiswe iingxaki zokungasebenzi kakuhle kobushushu obuphantsi kwiibhetri ze-lithium iron phosphate, inkqubo ye-BYD ethi "flash charging" ingenisa isixhobo sokufudumeza i-pulse ukugcina ukusebenza kokutshaja nokukhupha ibhetri ngokukhawuleza ngokuzifudumeza kwiindawo ezibandayo. Kwangaxeshanye, ukuze kujongwane nokufudumeza kwebhetri okubangelwa kukutshaja nokukhupha ibhetri ngamandla aphezulu, indawo yebhetri idityaniswe nenkqubo yokulawula ubushushu bokupholisa ulwelo oludibeneyo, olususa ngqo ubushushu bebhetri ngefriji.
Ngokuphathelele ukusebenza kokhuseleko, i-lithium iron phosphate iphinde yabonakalisa ixabiso layo. Ngokutsho kwe-BYD, ibhetri yayo yeblade "yokutshaja nge-flash" iphumelele ngokulula uvavanyo lokutyumza oluyi-1200 ton kunye novavanyo lokungqubana lwe-70km/h. Ulwakhiwo oluzinzileyo lweekhemikhali kunye neempawu ezithintela ilangatye ze-lithium iron phosphate kwakhona zibonelela ngesiqinisekiso esisisiseko sokhuseleko lwezithuthi zombane.
Ukujongana nengxaki yokutshaja
Mhlawumbi uninzi lwabantu alunalo ulwazi ngamandla asemgangathweni eemegawatt, kodwa kubalulekile ukuqonda ukuba i-1 megawatt isenokuba ngamandla efektri ephakathi, amandla afakiweyo esityalo samandla elanga esincinci, okanye ukusetyenziswa kombane kuluntu lwabantu abaliwaka.
Ewe, uyivile kakuhle. Amandla okutshaja emoto alingana nalawo omzi-mveliso okanye indawo yokuhlala. Isikhululo sokutshaja esingaphezulu kwemoto silingana nokusetyenziswa kombane kwesiqingatha sesitalato. Olu bungakanani bokusetyenziswa kombane buza kuba ngumceli mngeni omkhulu kwigridi yamandla yasezidolophini yangoku.
Asikuko ukuba akukho mali yokwakha izitishi zokutshaja, kodwa ukwakha izitishi zokutshaja kakhulu, kuyimfuneko ukuhlaziya igridi yamandla yesixeko sonke kunye nesitalato. Njengokwenza iidumpling ngokukodwa kwipleyiti yeviniga, le projekthi ifuna umgudu omkhulu. Ngamandla ayo angoku, i-BYD icwangcise kuphela ukwakhiwa kwezikhululo zokutshaja ze-"megawatt flash" ezingaphezu kwama-4000 kuzwelonke kwixesha elizayo.
Izikhululo zokutshaja nge-flash ezingama-4000 'zeemegawatt' azanelanga. "Iibhetri kunye" neemoto zokutshaja nge-flash "ziinyathelo lokuqala lokufikelela" kwi-oyile kunye nombane ngesantya esifanayo".
Ngenxa yophuhliso olukhulu kwiteknoloji yezithuthi zombane kunye neebhetri, ingxaki yokwenyani iqalile ukutshintshela ekwakhiweni kwezixhobo zombane kunye neenethiwekhi zamandla. Zombini i-BYD kunye ne-CATL, kunye nezinye iinkampani zebhetri kunye neebhetri kunye neebhetri eTshayina, zinokujongana namathuba amakhulu emarike kulo mba.
