Nkhaniyi idachokera ku nkhani yoyambirira ya Big Bit News
Pambuyo pa zaka za m'ma 1940, zida zamagetsi zakhala chida chopangira padziko lonse lapansi, ndipo chiwerengero chawo cholowera chawonjezeka kwambiri.Tsopano akhala chimodzi mwa zida zapakhomo zofunika kwambiri m'moyo wabanja wa mayiko otukuka.zida zamphamvu za dziko langa zidayamba kupanga zambiri m'zaka za m'ma 1970, ndipo zidakula m'ma 1990, ndipo kuchuluka kwa mafakitale kunapitilira kukula.M'zaka makumi awiri zapitazi, makampani opanga zida zamagetsi ku China akupitilizabe kupititsa patsogolo ntchito yosinthira magawo a ntchito padziko lonse lapansi.Komabe, ngakhale kuchuluka kwa msika wazinthu zapakhomo, sikunagwedezeke pamakampani akuluakulu amitundu yonse omwe akukhala pamsika wamagetsi apamwamba kwambiri.
Kusanthula kwa msika wa zida zamagetsi
Tsopano msika wa zida zamagetsi umagawidwa m'manja, zida zam'munda ndi zida zina.Msika wonse umafunikira zida zamagetsi kuti zitsimikizire kukhazikika ndi chitetezo, kukhala ndi mphamvu zambiri ndi makokedwe, phokoso lochepa, kukhala ndi telemetry yanzeru yamagetsi, ndipo ukadaulo wa zida zamagetsi ukusintha pang'onopang'ono, ndipo injini imakhala ndi torque yayikulu ndi mphamvu, ndipo imagwira ntchito bwino. .Kuyendetsa galimoto, moyo wautali wa batri, yaying'ono komanso yaying'ono, kapangidwe kotetezeka, IoT telemetry, kapangidwe kolephera.
Poyankha zofuna zatsopano za msika, opanga akuluakulu nthawi zonse akuwongolera luso lawo.Toshiba wabweretsa LSSL (palibe low speed sensor) luso, amene angathe kulamulira galimoto pa otsika liwiro popanda udindo sensa.LSSL imathanso kukonza magwiridwe antchito a inverter ndi mota., Chepetsani kugwiritsa ntchito mphamvu.
Nthawi zambiri, zida zamakono zamakono zikukula pang'onopang'ono mpaka kupepuka, zamphamvu kwambiri, ndikuwonjezera kulemera kwa mayunitsi mosalekeza.Nthawi yomweyo, msika ukupanga zida zamagetsi za ergonomic ndi zida zamagetsi zomwe zilibe zinthu zovulaza.Ndi chitukuko chosalekeza cha sayansi ndi luso lamakono, zida zamagetsi, monga chida chokhala ndi antchito owonjezereka, zidzatenga gawo lalikulu pa chuma cha dziko ndi miyoyo ya anthu, ndipo zida za mphamvu za dziko langa zidzasinthidwa.
Ntchito zambiri zamabatire a lithiamu
Ndi chitukuko cha miniaturization komanso kusavuta kwa zida zamagetsi, mabatire a lithiamu amagwiritsidwa ntchito kwambiri pazida zamagetsi.Kugwiritsa ntchito mabatire a lithiamu mu zida zamagetsi kwakula kuchokera ku zingwe zitatu mpaka zingwe 6-10.Kuwonjezeka kwa chiwerengero cha mankhwala amodzi omwe amagwiritsidwa ntchito kwabweretsa kuwonjezeka kwakukulu.Zida zina zamagetsi zilinso ndi mabatire otsala.
Ponena za mabatire a lithiamu omwe amagwiritsidwa ntchito pazida zamagetsi, padakali kusamvetsetsana pamsika.Amakhulupirira kuti ukadaulo wa batri wamagalimoto ndiukadaulo wapamwamba, wapamwamba komanso wotsogola.M’chenicheni, iwo sali.Mabatire a lithiamu omwe amagwiritsidwa ntchito pazida zamagetsi ayenera kugwiritsidwa ntchito pamalo okwera kwambiri komanso otsika kwambiri., Ndipo kuti agwirizane ndi kugwedezeka kwamphamvu, kuthamanga mofulumira ndi kumasulidwa mwamsanga, ndipo mapangidwe a chitetezo ndi ophweka, zofunikirazi sizotsika kuposa batri yamagetsi a galimoto, kotero zimakhala zovuta kwambiri kupanga mabatire apamwamba, apamwamba kwambiri.Ndi ndendende chifukwa cha zinthu zowawa izi kuti sizinali mpaka zaka zaposachedwa pomwe zida zazikulu zapadziko lonse lapansi zidayamba kugwiritsa ntchito mabatire a lithiamu m'magulu atatha zaka zambiri zotsimikizira ndi kutsimikizira.Chifukwa zida zamagetsi zili ndi zofunika kwambiri pamabatire ndipo gawo la certification ndi lalitali, ambiri aiwo sanalowe mgulu lamakampani opanga zida zamagetsi omwe ali ndi zotumiza zazikulu zapadziko lonse lapansi.
Ngakhale mabatire lifiyamu ndi chiyembekezo yotakata mu msika mphamvu chida, iwo ali bwino kuposa mphamvu mabatire mawu a mtengo (10% apamwamba kuposa mabatire mphamvu), phindu, ndi liwiro remittance, koma mayiko mphamvu chida zimphona kusankha lifiyamu batire makampani kwambiri kusankha, osati zimangofunika sikelo inayake mu mphamvu kupanga, komanso amafuna okhwima mkulu faifi yamphamvu cylindrical NCM811 ndi NCA kupanga njira mawu a R&D ndi mphamvu luso.Choncho, makampani amene akufuna kusintha mu mphamvu chida lifiyamu batire msika, popanda nkhokwe luso, n'zovuta kulowa dongosolo kotunga unyolo zimphona mayiko mphamvu chida.
Nthawi zambiri, 2025 isanafike, kugwiritsa ntchito mabatire a lithiamu mu zida zamagetsi kudzakula mwachangu.Aliyense amene atha kukhala pagawo la msika woyamba adzatha kupulumuka kukonzanso kwachangu kwamakampani amagetsi amagetsi.
Nthawi yomweyo, batire ya lithiamu imafunikira chitetezo chofananira.Neusoft Carrier nthawi ina adabweretsa chida champhamvu cha lithiamu batri chitetezo board mukulankhula.Chifukwa chomwe batire ya lithiamu imafunikira chitetezo imatsimikiziridwa ndi magwiridwe ake.Zinthu za batri ya lithiamu palokha zimatsimikizira kuti sizingachulukitsidwe, kuthamangitsidwa, kupitirira malire, kufupikitsa, ndi kutulutsidwa pa kutentha kwakukulu.Komanso, mabatire alibe mtheradi kugwirizana.Mabatire atapangidwa kukhala zingwe, kusagwirizana kwa mphamvu pakati pa mabatire kumapitilira malire ena, zomwe zingakhudze mphamvu yeniyeni ya batire yonse.Kuti tichite izi, tiyenera kulinganiza mabatire osagwirizana.
Mfundo zazikuluzikulu za kusalinganika kwa paketi ya batri zimachokera ku mbali zitatu: 1. Kupanga ma cell, kulakwitsa kwapang'onopang'ono (kuthekera kwa zida, kuwongolera khalidwe), 2. Kulakwitsa kwa ma cell (impedance, SOC status), 3. Cell self- kutulutsa Mlingo wosagwirizana [maselo a cell, kusintha kwa impedance, njira yamagulu (kuwongolera njira, kutsekereza), chilengedwe (malo otentha)].
Choncho, pafupifupi batri iliyonse ya lithiamu iyenera kukhala ndi bolodi yotetezera chitetezo, yomwe imapangidwa ndi IC yodzipatulira ndi zigawo zingapo zakunja.Itha kuyang'anira bwino ndikuletsa kuwonongeka kwa batri kudzera muchitetezo chotchinga, ndikuletsa kuyaka komwe kumachitika chifukwa cha kuchulukirachulukira, kutulutsa kwambiri komanso kuzungulira kwafupi.Zoopsa monga kuphulika.Monga batire iliyonse ya lithiamu-ion iyenera kukhazikitsa IC yoteteza batire, msika wa IC woteteza batire wa lithiamu ukukula pang'onopang'ono, ndipo chiyembekezo chamsika ndi chachikulu kwambiri.
