Ni izihe nyungu za 800V yumuvuduko ukabije wa buri wese ashyushye, kandi irashobora kwerekana ejo hazaza ha tram?

Guhangayikishwa cyane ni icyuho kinini kibuza iterambere ry’isoko ry’amashanyarazi, kandi igisobanuro cyihishe inyuma yisesengura ryitondewe ryimpungenge ni "kwihangana kugufi" no "kwishyuza buhoro". Kugeza ubu, usibye ubuzima bwa bateri, biragoye gutera intambwe ishimishije, bityo "kwishyuza byihuse" na "supercharge" nibyo byibandwaho muburyo bugezweho bwibigo bitandukanye byimodoka. Noneho800V Umuvuduko mwinshiurubuga rwabayeho.

Ku baguzi basanzwe, porogaramu ya 800V y’umuvuduko mwinshi utezwa imbere n’amasosiyete y’imodoka ni ijambo rya tekiniki gusa, ariko nk'ikoranabuhanga rikomeye mu gihe kizaza, rifitanye isano n'uburambe bw'imodoka, kandi tugomba gusobanukirwa muri rusange n'ikoranabuhanga rishya. . Kubwibyo, iyi mpapuro izakora isesengura ryimbitse rya 800V yumuvuduko mwinshi uturutse kubintu bitandukanye nk'ihame, ibisabwa, iterambere no kugwa.

Kuki ukeneye platform ya 800V?

Mu myaka ibiri ishize, hamwe n’ubwiyongere buhoro buhoro bw’imodoka z’amashanyarazi, umubare w’ibirundo byo kwishyuza wazamutse icyarimwe, ariko igipimo cy’ibirundo nticyagabanutse. Mu mpera za 2020, "igipimo cy’imodoka-ikirundo" cy’ibinyabiziga bishya by’imbere mu gihugu ni 2.9: 1 (umubare w’ibinyabiziga ni miliyoni 4.92 naho umubare w’ibirundo ni miliyoni 1.681). Muri 2021, igipimo cyimodoka nikirundo kizaba 3: 1, kitazagabanuka ahubwo kiziyongera. Igisubizo nuko igihe cyumurongo ari kirekire kuruta igihe cyo kwishyuza.

Noneho kubijyanye numubare wibikoresho byo kwishyuza ntibishobora gukomeza, kugirango ugabanye igihe cyakazi cyo kwishyiriraho ibirundo, tekinoroji yo kwishyuza byihuse irakenewe cyane.

Ubwiyongere bwumuvuduko wumuriro burashobora kumvikana gusa nkukwiyongera kwingufu zumuriro, ni ukuvuga P = U · I muri P (P: ingufu zumuriro, U: kwishyuza voltage, I: kwishyuza amashanyarazi). Kubwibyo, niba ushaka kongera ingufu zumuriro, komeza imwe mumashanyarazi cyangwa amashanyarazi adahindutse, kongera voltage cyangwa amashanyarazi birashobora kunoza ingufu zumuriro. Itangizwa rya platifomu nini cyane ni ukunoza uburyo bwo kwishyuza impera yikinyabiziga no kumenya kwishyurwa byihuse byimodoka.

800Vkubinyabiziga byamashanyarazi nibyo byingenzi guhitamo kwishyurwa byihuse. Kuri bateri yingufu, kwishyuza byihuse ningirakamaro kugirango wongere amashanyarazi yumuriro, bizwi kandi nkigipimo cyo kwishyuza; Kugeza ubu, amasosiyete menshi yimodoka ari mumiterere ya kilometero 1000 zo gutwara ibinyabiziga, ariko tekinoroji ya batiri iriho, niyo yaba yaratejwe imbere kuri bateri zikomeye, ikenera kandi ipaki yamashanyarazi ifite 100kWh zirenga, ibyo bikazageraho kwiyongera k'umubare w'utugingo ngengabuzima, niba imiyoboro rusange ya 400V ikomeje gukoreshwa, umubare w'utugingo ngengabuzima twiyongera, bigatuma kwiyongera kwa bisi. Bizana ikibazo gikomeye kubisobanuro byumuringa wumuringa hamwe nubushyuhe bwa pipe.

Niyo mpamvu, birakenewe guhindura urukurikirane rwimiterere ya selile ya batiri mumapaki ya bateri, kugabanya parallel no kongera urukurikirane, kugirango wongere amashanyarazi mugihe ukomeza imiyoboro ya platifomu murwego rwumvikana. Ariko, uko umubare wurukurikirane wiyongera, bateri yamashanyarazi ya voltage iziyongera. Umuvuduko ukenewe kuri paki ya batiri 100kWh kugirango ugere kuri 4C byihuse ni 800V. Kugirango uhuze nibikorwa byihuse byo kwishyuza byinzego zose za moderi, 800V yububiko bwamashanyarazi nuburyo bwiza.
