Eli nqaku lithatyathwe kwinqaku lokuqala leBit Bit News
Emva kweminyaka yee-1940, izixhobo zombane ziye zaba sisixhobo sokuvelisa amazwe ngamazwe, kwaye izinga lokungena kwazo liye landa kakhulu.Ngoku ziye zaba sesinye sezixhobo zekhaya eziyimfuneko kubomi bentsapho yamazwe ahambele phambili kwezoqoqosho.izixhobo zamandla elizwe lam zaqala ukungena kwimveliso yobuninzi kwi-1970s, kwaye yahluma kwi-1990s, kwaye isikali semizi-mveliso siphelele siqhubeka sisanda.Kule minyaka ingamashumi amabini idlulileyo, ishishini lezixhobo zamandla eTshayina liye laqhubeleka liphuhla kwinkqubo yokwenza ukudluliselwa kolwahlulo lwabasebenzi kumazwe ngamazwe.Nangona kunjalo, ngaphandle kokunyuka kwesabelo semarike yeempawu zasekhaya, abakayishukumisi imeko yeenkampani ezinkulu zamazwe ngamazwe ezithatha imarike yezixhobo zamandla eziphezulu.
Uhlalutyo lwemarike yesixhobo sombane
Ngoku imarike yezixhobo zamandla yahlulahlulwe kakhulu kwizixhobo eziphathwayo, izixhobo zegadi kunye nezinye izixhobo.Imarike yonke ifuna izixhobo zamandla ukuqinisekisa uzinzo kunye nokhuseleko, amandla amaninzi kunye ne-torque, ingxolo encinci, i-telemetry yesixhobo se-elektroniki esihlakaniphile, kwaye iteknoloji yezixhobo zamandla iyatshintsha ngokuthe ngcembe, kwaye injini ine-torque ephezulu kunye namandla, kwaye isebenze ngakumbi. .Ukuqhutywa kweemoto, ubomi bebhetri obude, i-compact kunye nesayizi encinci, uyilo olungaphumeleliyo, i-telemetry ye-IoT, uyilo olungaphumeleliyo.
Ukuphendula kwimfuno entsha yeemarike, abavelisi abakhulu bahlala bephucula iteknoloji yabo.I-Toshiba izise i-LSSL (ayikho i-speed sensor ephantsi) iteknoloji, ekwazi ukulawula i-motor ngesantya esiphantsi ngaphandle kwenzwa yendawo.I-LSSL inokuphucula ukusebenza kakuhle kwe-inverter kunye nemoto., Nciphisa ukusetyenziswa kwamandla.
Ngokubanzi, izixhobo zamandla zanamhlanje zikhula kancinci kancinci, zinamandla ngakumbi, kwaye zikhula ngokuqhubekayo ubunzima beyunithi.Kwangaxeshanye, imakethi iphuhlisa izixhobo zamandla e-ergonomic kunye nezixhobo zamandla ezingenazo izinto eziyingozi.Ngophuhliso oluqhubekayo lwenzululwazi nobuchwepheshe, izixhobo zombane, njengesixhobo esinabasebenzi abondisiweyo, ziya kudlala indima enkulu kuqoqosho lwesizwe nakubomi babantu, kwaye izixhobo zombane zelizwe lam ziya kuhlaziywa.
Uluhlu olubanzi lwezicelo zeebhetri ze-lithium
Ngomkhwa wokuphuhliswa kwe-miniaturization kunye nokulula kwezixhobo zombane, iibhetri ze-lithium zisetyenziswa ngokubanzi kwizixhobo zombane.Ukusetyenziswa kweebhetri ze-lithium kwizixhobo zamandla kukhule ukusuka kwiintambo ezi-3 ukuya kwii-6-10 iintambo.Ukwanda kwenani leemveliso ezisetyenzisiweyo kuzise ukwanda okukhulu.Ezinye izixhobo zombane zikwaxhotyiswe ngeebhetri ezisecaleni.
Ngokumalunga neebhetri ze-lithium ezisetyenziswa kwizixhobo zamandla, kusekho ukungaqondi kakuhle kwiimarike.Bakholelwa ukuba itekhnoloji yebhetri yamandla emoto iphezulu, iphucukile kwaye ikwinqanaba letekhnoloji.Enyanisweni, azinjalo.Iibhetri ze-lithium ezisetyenziselwa izixhobo zamandla kufuneka zisetyenziswe kwiindawo eziphakamileyo eziphezulu kunye neziphantsi zokushisa., Kwaye ukulungelelanisa ukunyakaza okunamandla, ukutshaja ngokukhawuleza kunye nokukhululwa ngokukhawuleza, kunye noyilo lokukhusela lulula, ezi mfuno azikho ngaphantsi kwebhetri yamandla esithuthi, ngoko ngokwenene kunzima kakhulu ukwenza ukusebenza okuphezulu, iibhetri eziphezulu.Kungenxa yezi meko zinzima ukuba akuzange kube kwiminyaka yakutshanje apho izixhobo zamandla zamazwe ngamazwe zaqala ukusebenzisa iibhetri ze-lithium zasekhaya kwiibhetshi emva kweminyaka yokuqinisekisa kunye nokuqinisekiswa.Ngenxa yokuba izixhobo zombane zineemfuno eziphezulu kakhulu kwiibhetri kwaye nesigaba soqinisekiso side noko, uninzi lwazo alukhange lungene kwikhonkco lonikezelo lweenkampani zezixhobo zamandla ezinothutho olukhulu lwamazwe ngamazwe.
Nangona iibhetri ze-lithium zinethemba elibanzi kwimarike yesixhobo samandla, zingcono kuneebhetri zamandla ngokwexabiso (i-10% ephezulu kuneebhetri zamandla), inzuzo, kunye nesantya sokuthunyelwa kwentlawulo, kodwa izixhobo zamandla zamazwe ngamazwe zikhetha iinkampani zebhetri ze-lithium zikhetha kakhulu, hayi. ifuna kuphela isikali esithile kumthamo wemveliso, kodwa ifuna eqolileyo i-nickel cylindrical NCM811 kunye neenkqubo zemveliso zeNCA ngokwemigaqo ye-R&D kunye namandla obugcisa.Ngoko ke, kwiinkampani ezifuna ukuguqula kwisixhobo samandla se-lithium ibhetri yemarike, ngaphandle koovimba bezobugcisa, kunzima ukungena kwinkqubo yokubonelela ngezixhobo zamandla zamazwe ngamazwe.
Ngokubanzi, ngaphambi kwe-2025, ukusetyenziswa kweebhetri ze-lithium kwizixhobo zamandla kuya kukhula ngokukhawuleza.Nabani na onokuhlala kweli candelo lentengiso kuqala uya kuba nakho ukusinda kuhlengahlengiso olukhawulezileyo lweenkampani zebhetri zamandla.
Ngexesha elifanayo, ibhetri ye-lithium idinga ukukhuselwa okuhambelanayo.I-Neusoft Carrier yakha yazisa ibhodi yokukhusela ibhetri ye-lithium kwintetho.Isizathu sokuba ibhetri ye-lithium idinga ukukhuselwa inqunywe ngokusebenza kwayo.Izinto eziphathekayo zebhetri ye-lithium ngokwayo inquma ukuba ayinakugqithiswa, ikhutshwe, i-overcurrent, i-short circuited, kwaye ikhutshwe kwiqondo lokushisa eliphezulu.Ukongeza, iibhetri azinakho ukuhambelana ngokupheleleyo.Emva kokuba iibhetri zenziwe zibe yimicu, ukungahambelani kwamandla phakathi kweebhetri kudlula umda othile, okuya kuchaphazela amandla okwenene asebenzisekayo eebhetri zonke.Ukuza kuthi ga ngoku, kufuneka silinganise iibhetri ezingahambelaniyo.
Izinto eziphambili zokungalingani kwepakethi yebhetri zivela kwimiba emithathu: 1. Ukuveliswa kweeseli, impazamo ye-sub-capacity (ubunakho besixhobo, ulawulo lomgangatho), 2. Impazamo yokudibanisa i-cell (impedance, i-SOC status), 3. I-cell self- ukukhupha Ireyithi engalinganiyo [inkqubo yeseli, utshintsho lwe-impedance, inkqubo yeqela (ulawulo lwenkqubo, ukugquma), indawo (intsimi ye-thermal)].
Ngoko ke, phantse yonke ibhetri ye-lithium kufuneka ixhotyiswe ngebhodi yokukhusela ekhuselekileyo, ehlanganiswe ne-IC ezinikeleyo kunye namacandelo amaninzi angaphandle.Iyakwazi ukubeka iliso ngokufanelekileyo kwaye ithintele umonakalo kwibhetri ngokusebenzisa i-loop yokukhusela, kwaye ithintele ukutshisa okubangelwa ukugqithiswa, ukukhutshwa kunye nesiphaluka esifutshane.Iingozi ezifana nokudubula.Njengoko ibhetri ye-lithium-ion nganye kufuneka ifake i-IC yokukhusela ibhetri, i-lithium yokukhusela ibhetri ye-IC ikhula ngokuthe ngcembe, kwaye ithemba lemarike libanzi kakhulu.
