Kuki bateri y'icyuma cya BYD ubu ari ingingo ishyushye cyane
"Bateri y'icyuma ya BYD", imaze igihe kinini ivugwaho rumwe mu nganda, yashyize ahagaragara uko igaragara koko.
Birashoboka ko vuba aha abantu benshi bagiye bumva ijambo "bateri y'umukara", ariko wenda ntibarimenyereye cyane, bityo uyu munsi tuzasobanura mu buryo burambuye ijambo "bateri y'umukara".
Ni nde wabanje gutanga batiri y'icyuma
Umuyobozi wa BYD, Wang Chuanfu, yatangaje ko "bateri y'umukara" ya BYD (ubwoko bushya bwa bateri za fosfeti ya lithium iron) izatangira gukorwa ku bwinshi mu ruganda rwa Chongqing muri Werurwe uyu mwaka, no muri Kamena izashyirwa ku rutonde rwa mbere rwa Han EV. Hanyuma BYD yongeye kugaragara mu makuru y'ibinyabiziga ndetse n'iby'imari by'ibitangazamakuru bikomeye.
Impamvu Bateri y'Ibyuma
Bateri y'icyuma yasohotse na BYD ku ya 29 Werurwe 2020. Izina ryayo ryuzuye ni bateri ya lithium iron phosphate yo mu bwoko bwa blade, izwi kandi ku izina rya "bateri ya super lithium iron phosphate". Bateri ikoresha ikoranabuhanga rya lithium iron phosphate, izabanza gushyirwamo ubwoko bwa BYD "Han".
Mu by’ukuri, "bateri y'icyuma" ni ubwoko bushya bwa bateri ya fosifate ya lithium iherutse gusohorwa na BYD, mu by’ukuri, BYD yibanda ku iterambere rya "fosifate ya fosifate ya super lithium iron" binyuze mu bushakashatsi bw’imyaka myinshi, wenda uruganda rwifuza ko binyuze mu izina risobanutse neza kandi ry’ikigereranyo, rurushaho kwitabwaho no kugira uruhare.
Imbonerahamwe y'imiterere ya bateri y'icyuma
Ugereranyije na bateri ya lithium iron phosphate ya BYD yabanje, urufunguzo rwa "bateri y'icyuma" rukorwa nta module, rushyirwa mu buryo butaziguye muri bateri (ni ukuvuga ikoranabuhanga rya CTP), bityo bikanoza cyane imikorere yo guhuza.
Ariko mu by’ukuri, BYD si yo ruganda rwa mbere rukoresha ikoranabuhanga rya CPT. Nk’uruganda runini ku isi rukora bateri zikoresha ingufu, Ningde Times yakoresheje ikoranabuhanga rya CPT mbere ya BYD. Muri Nzeri 2019, Ningde Times yagaragaje iri koranabuhanga mu imurikagurisha rya Frankfurt Motor Show.
Tesla, Ningde Times, BYD na Hive Energy, batangiye gutera imbere kandi batangaza ko bazakora ku bwinshi ibicuruzwa bifitanye isano na CTP, kandi paki z'amashanyarazi zidafite module zirimo kuba inzira y'ikoranabuhanga ikoreshwa cyane.
Paki gakondo ya bateri ya ternari lithium
Icyo bita module, ni igice cy'ibice bireba bigize module, gishobora kandi kumvikana nk'igitekerezo cyo guteranya ibice. Muri uru rwego rwa bateri, utunyangingo twinshi, imirongo iyobora, ibice byo gupima hamwe n'ibice bimwe na bimwe by'ingenzi bishyigikiwe mu miterere y'imiterere bihurizwa hamwe kugira ngo bikore module, nanone yitwa module.
Paki ya bateri ya Ningde Times CPT
CPT (cell to pack) ni uburyo bwo guhuza utunyangingo mu ipaki ya bateri. Bitewe no gukuraho umurongo wo guteranya bateri, umubare w'ibice bya bateri ugabanukaho 40%, igipimo cy'ikoreshwa rya bateri ya CTP cyongerwaho 15%-20%, kandi umusaruro wiyongeraho 50%, ibi bigabanya cyane ikiguzi cyo gukora bateri y'amashanyarazi.
Bite se ku giciro cya batiri y'icyuma?
Tuvuze ku giciro, bateri ya fosfeti ya lithiamu ubwayo ntikoresha ibyuma bidasanzwe nka cobalt, igiciro ni inyungu yayo. Birumvikana ko isoko rya bateri ya lithiamu ya ternary yo mu 2019 ritanga hafi 900 RMB / kW-h, mu gihe bateri ya fosfeti ya lithiamu ya fer iri ku giciro cya 700 RMB / kW-h, mu gihe kizaza hazashyirwa ku rutonde rwa Han urugero, intera yayo ishobora kugera kuri 605km, bateri iteganijwe kuba irenga 80kW-h, ikoreshwa rya bateri ya fosfeti ya lithiamu ya fer rishobora kuba nibura 16.000 RMB (2355.3 USD) ihendutse. Tekereza indi modoka nshya ikoresha ingufu mu gihugu ifite igiciro n'uburebure nk'ubwa BYD Han, bateri ipaki yonyine ifite inyungu ya 20.000 RMB (2944.16 USD), bityo biragaragara ko ikomeye cyangwa idakomeye.
Mu gihe kizaza, BYD Han EV ifite verisiyo ebyiri: verisiyo ya moteri imwe ifite ingufu za 163kW, torque ya 330N-m na NEDC ya 605km; verisiyo ya moteri ebyiri ifite ingufu za 200kW, torque ya 350N-m ntarengwa na NEDC ya 550km.
Ku itariki ya 12 Kanama, byatangajwe ko bateri y'icyuma ya BYD yagejejwe kuri Gigafactory ya Tesla Berlin, biteganijwe ko izaba ifite bateri y'imodoka za Tesla zitari ku murongo mu mpera za Kanama kugeza mu ntangiriro za Nzeri, mu gihe uruganda runini rwa Tesla rwo muri Shanghai rudateganya gukoresha bateri za BYD.
teslamag.de yemeje ukuri kw'aya makuru. Bivugwa ko Model Y ifite bateri za BYD yahawe uburenganzira bwo gukoresha ubwoko bw'imodoka buturutse mu Muryango w'Ubumwe bw'u Burayi, bwemejwe na Minisiteri y'Ubwikorezi y'Abaholandi (Minisiteri y'Ubwikorezi y'Abaholandi) ku ya 1 Nyakanga 2022. Muri iyo nyandiko, Model Y nshya yitwa Type 005, ifite ubushobozi bwa bateri ya 55 kWh n'uburebure bwa kilometero 440.
Ni izihe nyungu za batiri z'icyuma
Umutekano:Mu myaka ya vuba aha, impanuka zijyanye n'umutekano w'ibinyabiziga bikoresha amashanyarazi zakunze kugaragara, kandi inyinshi muri zo ziterwa n'inkongi z'umuriro wa bateri. "Bateri y'icyuma" ishobora kuvugwa ko ari yo irinda umutekano mwiza ku isoko. Dukurikije igerageza rya BYD ryasohotse ku igeragezwa ryo kwinjira mu nzara za bateri, tubona ko "bateri y'icyuma" nyuma yo kwinjira, ubushyuhe bwa bateri bushobora no kugumana hagati ya 30-60 ℃, ibi biterwa nuko umurongo wa bateri y'icyuma ari muremure, ubuso bunini kandi ubushyuhe buhita bushira. Ouyang Minggao, umuhanga mu by'ubumenyi bw'Abashinwa, yagaragaje ko imiterere ya bateri y'icyuma ituma itanga ubushyuhe buke kandi igakuraho ubushyuhe vuba iyo ikora ku buryo bugufi, kandi yasuzumye imikorere yayo mu "igerageza ryo kwinjira mu nzara" nk'iy'ingirakamaro.
Ubucucike bw'ingufu nyinshi:Ugereranyije na bateri za lithium ternary, bateri za fosfeti ya lithium fer zitekanye kandi zifite ubuzima burebure, ariko mbere muri bateri ubucucike bw'ingufu bwashyizwemo umutwe. Ubu ubucucike bwa bateri y'icyuma wh/kg ugereranyije n'ubwa bateri zabanjirije iyi, nubwo ubucucike bw'ingufu bwa wh/l bwiyongeraho 9%, ariko bwiyongeraho kugeza kuri 50%. Ni ukuvuga ko ubushobozi bwa bateri ya "blade battery" bushobora kwiyongeraho 50%.
Bateri iramba:Dukurikije igerageza, igihe cyo gushyushya batiri y'icyuma kirenga inshuro 4500, ni ukuvuga ko igihe cyo gushyushya batiri kiri munsi ya 20% nyuma yo gushyushya inshuro 4500, igihe cyo gushyushya batiri kirenga inshuro 3 za batiri ya lithium ternary, kandi igihe kingana n'ikirometero cya batiri y'icyuma gishobora kurenza kilometero miliyoni 1.2.
Ni gute wakora akazi keza ku buso bw'igishishwa cy'imbere, isahani ikonjesha, igipfukisho cyo hejuru n'icyo hasi, isahani, baffle n'ibindi bice kugira ngo ugere ku bipimo by'umutekano byo gukingira, gukingira ubushyuhe, gukingira umuriro, kwirinda umuriro no kuzuza ibisabwa mu gukora mu buryo bwikora? Ni imbogamizi ikomeye n'inshingano by'uruganda rukora irangi muri iki gihe gishya.
