Intangiriro ：
Kwishyuza iminota 5 hamwe na kilometero 400! Ku ya 17 Werurwe, BYD yasohoye sisitemu ya "megawatt flash charging", izafasha ibinyabiziga byamashanyarazi kwishyurwa vuba nka lisansi.
Ariko, kugirango tugere ku ntego ya "peteroli n'amashanyarazi ku muvuduko umwe", BYD isa nkaho yageze ku mbibi za batiri ya lithium fer fosifate. Nubgo ubwinshi bwingufu za lithium fer fosifate ubwayo iri hafi kurwego rwayo, BYD iracyakomeza gushushanya ibicuruzwa no gutezimbere ikoranabuhanga bikabije.
Kina bikabije! 10C lithium fer fosifate
Ubwa mbere, dukurikije amakuru yashyizwe ahagaragara n’abanyamakuru ba BYD, tekinoroji ya flash ya BYD ikoresha ibicuruzwa byitwa "flash charging blade bateri", kugeza na n'ubu bikaba ari ubwoko bwa batiri ya lithium fer fosifate.
Ibi ntibisenya gusa ubutware bwa bateri ya lithium yo mu rwego rwo hejuru nka bateri nini ya nikel ternary yo hejuru ku isoko ryihuta ryihuta, ariko kandi bituma BYD ituma imikorere ya fosifate ya lithium fer ikomeza gukabya, bigatuma BYD ikomeza agaciro kayo ku isoko mu nzira y’ikoranabuhanga ya batiri ya lisiyumu ya fosifate.
Dukurikije amakuru yashyizwe ahagaragara na BYD, BYD imaze kugera ku mbaraga zingana na megawatt 1 (1000 kWt) kuri moderi zimwe na zimwe nka Han L na Tang L, kandi flash yamashanyarazi yiminota 5 irashobora kuzuza ibirometero 400. Bateri ya 'flash charging' igeze ku gipimo cya 10C.
Ni ikihe gitekerezo? Ku bijyanye n’amahame ya siyansi, kuri ubu bizwi mu nganda ko ingufu za batiri za lithium fer fosifate yegereye imipaka. Mubisanzwe, kugirango harebwe ingufu nyinshi, abayikora bazatanga bimwe mubyo bashinzwe no gusohora imikorere. Mubisanzwe, 3-5C isohoka ifatwa nkigipimo cyiza cyo gusohora bateri ya lithium fer fosifate.
Ariko, kuriyi nshuro BYD yongereye igipimo cyo gusohora fosifate ya lithium fer igera kuri 10C, ntibisobanura gusa ko ikigezweho cyikubye hafi kabiri, ariko kandi bivuze ko kurwanya imbere hamwe ningorane zo gucunga ubushyuhe byikubye kabiri.
BYD ivuga ko hashingiwe ku cyuma, "bateri ya flash charger" ya BYD itunganya imiterere ya electrode ya batiri ya blade, igabanya 50% yo kwimuka kwa lithium ion, bityo bikagera ku nshuro ya mbere yo kwishyuza hejuru ya 10C ku nshuro ya mbere.
Ku bikoresho byiza bya electrode, BYD ikoresha ubuziranenge bwinshi, umuvuduko mwinshi, hamwe nubucucike bukabije bwibisekuru bya kane bya lithium fer fosifate, hamwe nuburyo bwo kumenagura nanoscale, inyongeramusaruro zidasanzwe, hamwe nuburyo bwo kubara ubushyuhe bwo hejuru. Inzira nziza yimbere yimbere hamwe ninzira ngufi yo gukwirakwiza kuri lithium ion byongera umuvuduko wimuka wa lithium ion, bityo bikagabanya kurwanya imbere ya bateri no kunoza imikorere yisohoka.
Mubyongeyeho, mubijyanye no guhitamo electrode mbi na electrolytite, birakenewe kandi guhitamo ibyiza mubyiza. Gukoresha ibishushanyo mbonera bifite ubuso bwihariye kandi hiyongereyeho ingufu za PEO (polyethylene oxyde) electrolytite nazo zabaye ibintu nkenerwa kugirango dushyigikire bateri 10C ya lithium fer fosifate.
Muri make, kugirango tugere ku bikorwa bigezweho, BYD isigarana amafaranga. Mu kiganiro n’abanyamakuru, igiciro cya BYD Han L EV gifite bateri ya "flash charging" kigeze kuri 270000-350000, kikaba kiri hejuru y’amafaranga 70000 ugereranije n’igiciro cyacyo cyo mu bwoko bwa 2025 EV gifite ubwenge bwo gutwara (701KM Icyubahiro).
Ni ubuhe buzima n'umutekano bya bateri zishyuza?
Nibyo, kubuhanga buhanitse, kubahenze ntabwo arikibazo. Buri wese aracyahangayikishijwe n'ubwiza n'umutekano by'ibicuruzwa. Ku bijyanye n'iki kibazo, Lian Yubo, Visi Perezida Nshingwabikorwa wa BYD Group, yatangaje ko bateri zishyuza flash zishobora kumara igihe kirekire kabone niyo zaba zishyuwe ku gipimo cyo hejuru cyane, hamwe na 35% by'ubuzima bwa cycle.
Birashobora kuvugwa ko igisubizo cya BYD muriki gihe ari cyiza kandi cyuzuye ubuhanga, byibuze ntahakana ingaruka zokwishyurwa hejuru mubuzima bwa bateri.
Kuberako mubisanzwe, kwishyuza byihuse no gusohora bizagira ingaruka zidasubirwaho kumiterere ya bateri. Byihuta kwishyuza no gusohora umuvuduko, niko ingaruka nyinshi mubuzima bwa bateri. Kubijyanye no kwishyuza, gukoresha igihe kirekire kugabanya ubuzima bwa bateri 20% kugeza 30%. Kubwibyo, abayikora benshi barasaba kwishyuza birenze urugero byihutirwa.
Bamwe mubakora ibicuruzwa bazashyiraho amafaranga arenze urugero ashingiye kubuzima bwa cycle ya bateri ubwayo. Igabanuka ryubuzima bwa bateri ryatewe no kwishyuza birenze urugero byongerwaho nubuzima bwubuzima bwa bateri nuwabikoze, amaherezo bigatuma ibicuruzwa byose bikomeza kwishyurwa neza no gusohora mubikorwa byateganijwe.
Byongeye kandi, kugirango tugere kuri "flash charging", BYD yanashyize mubikorwa gahunda yo kuzamura sisitemu hafi yintege nke za bateri ya fosifate ya lithium na sisitemu yose itanga amashanyarazi.
Kugirango hishyurwe ibitagenda neza byubushyuhe buke muri bateri ya lithium fer fosifate, sisitemu ya "flash charging" ya BYD itangiza igikoresho cyo gushyushya pulse kugirango gikomeze kwihuta no gusohora imikorere ya bateri binyuze mu gushyushya ubwayo ahantu hakonje. Muri icyo gihe, kugira ngo duhangane n’ubushyuhe bwa batiri buterwa no kwishyurwa n’umuriro mwinshi no gusohora, icyumba cya batiri cyahujwe na sisitemu yo gukonjesha ubushyuhe bwo gukonjesha, ikuraho mu buryo butaziguye ubushyuhe bwa batiri binyuze muri firigo.
Ku bijyanye n’imikorere yumutekano, lithium fer fosifate yongeye kwerekana agaciro kayo. Nk’uko BYD ibitangaza, bateri ya "flash charging" ya blade yoroheje yatsinze ikizamini cya toni 1200 yo guhonyora hamwe n'ikizamini cyo kugongana 70km / h. Imiterere yimiti ihamye hamwe na flame retardant ya lithium fer fosifate yongeye gutanga garanti yingenzi kumutekano wibinyabiziga byamashanyarazi.
Guhura n'ikibazo cyo kwishyuza
Birashoboka ko abantu benshi badafite igitekerezo cyingufu za megawatt, ariko ni ngombwa kumva ko megawatt 1 ishobora kuba imbaraga zuruganda ruciriritse, ubushobozi bwashyizweho n’uruganda ruciriritse rukomoka ku mirasire y'izuba, cyangwa gukoresha amashanyarazi y’umuryango wabantu igihumbi.
Nibyo, wabyumvise neza. Imbaraga zo kwishyuza imodoka zingana niz'uruganda cyangwa ahantu ho gutura. Sitasiyo yumuriro ihwanye no gukoresha amashanyarazi igice cyumuhanda. Iki gipimo cyo gukoresha amashanyarazi kizaba ikibazo gikomeye kuri gride y'amashanyarazi yo mumijyi.
Ntabwo ari uko nta mafranga yo kubaka sitasiyo yishyuza, ahubwo ni ukubaka sitasiyo yumuriro, birakenewe kuvugurura umujyi wose numuyoboro wamashanyarazi. Nkuko gukora ibibyimba byumwihariko kubisahani ya vinegere, uyu mushinga usaba imbaraga nyinshi. Nimbaraga zubu, BYD yateguye gusa kubaka sitasiyo zirenga 4000 "megawatt flash charging" mu gihugu hose.
4000 'megawatt flash charging station' mubyukuri ntabwo bihagije. Amashanyarazi ya "bateri" na "flash charging" imodoka nintambwe yambere yo kugera kuri "peteroli n'amashanyarazi kumuvuduko umwe".
Hamwe niterambere ryibinyabiziga byamashanyarazi nubuhanga bwa batiri, ikibazo nyacyo cyatangiye guhinduka mukubaka ibikoresho byamashanyarazi numuyoboro. BYD na CATL, kimwe nandi masosiyete akoresha bateri n’amashanyarazi mu Bushinwa, barashobora guhura n’amahirwe menshi ku isoko muri urwo rwego.
