Mu myaka ya vuba aha, inkongi z'umuriro zikoresha amashanyarazi ziracyagaragara cyane, cyane cyane mu gihe cy'ubushyuhe bwinshi bw'impeshyi, umuriro w'amashanyarazi woroshye gushya mu buryo butunguranye!
Nk’uko byatangajwe n’itsinda ry’igihugu rishinzwe ubutabazi bw’umuriro ryo mu 2021 ryakiriye amakuru ya polisi n’ay’inkongi yashyizwe ahagaragara n’Ibiro bishinzwe ubutabazi bw’umuriro muri Minisiteri y’Ubutabazi bw’Ibiza, inkongi zigera ku 18.000 zatewe n’imodoka zikoresha amashanyarazi zifite amapine abiri n’amabati yazo byagaragaye mu gihugu hose, zigahitana abantu 57. Nk’uko byatangajwe, mu gice kimwe cya kabiri cy’umwaka wa 2022 gusa, muri uyu mwaka habaye inkongi 26 z’imodoka zikoresha amashanyarazi zifite amapine abiri i Yantai.
Ni iki gitera inkongi z'umuriro zikoresha amashanyarazi zigurumana kenshi?
Impamvu nyamukuru itera gutwika mu buryo bwikora kw'imodoka ifite amapine abiri ni ugutwika kwa bateri za lithium, icyo bita gutwika kwa thermal ni uruhererekane rw'ibikorwa biterwa n'ibintu bitandukanye, kandi ubushyuhe bushobora gutuma ubushyuhe bwa bateri buzamukaho dogere ibihumbi, bigatera gutwika mu buryo bwikora. Bateri y'imodoka ifite amapine abiri irimo gushyushya cyane, gutobora, ubushyuhe bwinshi, gufunga umurongo mugufi, kwangirika kw'inyuma n'izindi mpamvu bitera gutwika kwa thermal mu buryo bworoshye.
Uburyo bwo kwirinda gushyuha cyane
Gutera ubushyuhe bwinshi ni byinshi, bityo hagomba gufatwa ingamba nyinshi zo gukumira ubushyuhe bwinshi.
Impamvu nyamukuru ituma ubushyuhe bugenda ni "ubushyuhe", kugira ngo bateri ikore ku bushyuhe bukwiye, kugira ngo hirindwe ko ubushyuhe bugenda butera. Ariko, mu gihe cy'ubushyuhe bwinshi bw'impeshyi, "ubushyuhe" ntibushobora kwirindwa, icyo gihe ugomba gutangirira kuri bateri, kugira ngo bateri za lithiamu-ion zigire ubushobozi bwo kurwanya ubushyuhe no gukwirakwiza ubushyuhe neza.
Mbere na mbere, abaguzi bagomba kwita ku miterere ijyanye na bateri za lithium iyo bagura imodoka zikoresha amashanyarazi zifite amapine abiri, kandi niba ibikoresho by'imbere mu gasanduku ka bateri bifite ubushobozi bwo kurwanya ubushyuhe n'imikorere myiza yo gukwirakwiza ubushyuhe. Icya kabiri, niba umuhuza uhujwe na bateri iri imbere mu modoka y'amashanyarazi ufite ubushobozi bwo kurwanya ubushyuhe bwinshi, kugira ngo umuhuza utazagabanuka cyangwa ngo unanirane n'ubushyuhe bwinshi, kugira ngo barebe ko umuhuza ugenda neza kandi birinde ko habaho umuhuza ugufi.
Nk'inzobere mu guhuza imodoka zikoresha amashanyarazi, AmasS ifite uburambe bw'imyaka 20 mu bushakashatsi no guteza imbere imiyoboro y'amashanyarazi ya lithium, kandi itanga ibisubizo byo guhuza imodoka zikoresha amashanyarazi ku bigo bibiri by'amashanyarazi bifite amapine nka SUNRA, AIMA, YADEA. Imiyoboro y'amashanyarazi ifite amapine abiri ifite ubushyuhe bwinshi ikoresha PBT ifite ubushyuhe bukabije, irwanya ikirere n'imiterere myiza y'amashanyarazi, kandi aho ishongesha PBT ifite amashanyarazi ni 225-235℃.
Imikorere ihamye y’igerageza n’amahame meza yo gupima ni byo shingiro ryo kwemeza ubuziranenge bw’umuyoboro w’imodoka zikoresha amashanyarazi ufite amapine abiri
Laboratwari ya Amass
Ibikoresho bikoresha amashanyarazi bifite ubushyuhe bwinshi byatsinze ikizamini cyo kugabanya umuriro, imikorere yabyo igera kuri V0 igabanya umuriro, bishobora no kugera ku bushyuhe buri hagati ya -20 ° C ~ 120 ° C. Kugira ngo bikoreshwe mu bushyuhe buri hejuru, igice cy'ingenzi cy'ibinyabiziga bifite amashanyarazi gifite ubushyuhe bwinshi ntikizagabanuka bitewe n'ubushyuhe bwinshi, bigatuma habaho umuvuduko muke.
Uretse guhitamo bateri n'ibiyigize, ubwiza bw'icyuma gikoresha amashanyarazi, igihe cyo gusharija ni kirekire cyane, ndetse no guhindura imodoka y'amashanyarazi ifite amapine abiri mu buryo butemewe n'amategeko ni ingenzi mu kunoza imikorere y'umutekano wa bateri ya lithium y'imodoka y'amashanyarazi.
