Lesi sihloko sithathwe esihlokweni sokuqala se-Big Bit News
Ngemva kweminyaka yawo-1940, amathuluzi kagesi asephenduke ithuluzi lokukhiqiza lamazwe ngamazwe, futhi izinga lawo lokungena liye landa kakhulu.Manje seziphenduke enye yezinto zasendlini ezibalulekile empilweni yomndeni yamazwe athuthukile.amathuluzi kagesi ezwe lami aqala ukungena ekukhiqizeni ngobuningi ngeminyaka yawo-1970, futhi achuma ngawo-1990, futhi isilinganiso sezimboni sezimboni saqhubeka nokukhula.Kule minyaka engamashumi amabili edlule, imboni yamathuluzi kagesi yaseShayina iqhubekile nokuthuthuka ohlelweni lokudluliswa kokuhlukaniswa kwemisebenzi yamazwe ngamazwe.Kodwa-ke, naphezu kokwenyuka kwesabelo semakethe yemikhiqizo yasekhaya, azikanyakazi isimo sezinkampani ezinkulu zamazwe ngamazwe ezithatha imakethe yamathuluzi kagesi asezingeni eliphezulu.
Ukuhlaziywa kwemakethe yamathuluzi kagesi
Manje imakethe yamathuluzi kagesi ihlukaniswe ikakhulukazi ngamathuluzi aphathwayo, amathuluzi engadini namanye amathuluzi.Imakethe yonke idinga amathuluzi kagesi ukuqinisekisa ukuzinza nokuphepha, ibe namandla engeziwe kanye ne-torque, umsindo omncane, i-telemetry yethuluzi le-elekthronikhi ehlakaniphile, nobuchwepheshe bamathuluzi amandla buyashintsha kancane kancane, futhi injini ine-torque ephakeme namandla, futhi isebenza kahle kakhulu. .Ukushayela kwezimoto, impilo yebhethri ende, usayizi ohlangene futhi omncane, umklamo ongaphumeleli, i-IoT telemetry, idizayini ehlulekayo.
Ekuphenduleni isidingo semakethe entsha, abakhiqizi abakhulu bahlala bethuthukisa ubuchwepheshe babo.I-Toshiba ilethe ubuchwepheshe be-LSSL (ayikho inzwa yejubane eliphansi), obungakwazi ukulawula imoto ngesivinini esiphansi ngaphandle kwenzwa yendawo.I-LSSL ingathuthukisa nokusebenza kahle kwe-inverter kanye ne-motor., Yehlisa ukusetshenziswa kwamandla.
Ngokuvamile, amathuluzi wamandla wanamuhla akhula kancane kancane, abe namandla kakhulu, futhi akhule ngokuqhubekayo isisindo seyunithi.Ngasikhathi sinye, imakethe ithuthukisa amathuluzi wamandla we-ergonomic namathuluzi kagesi angenazo izinto eziyingozi.Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, amathuluzi kagesi, njengethuluzi elinabasebenzi abengeziwe, azodlala indima enkulu emnothweni kazwelonke nasezimpilweni zabantu, futhi amathuluzi kagesi ezwe lami azothuthukiswa.
Uhla olubanzi lwezicelo zamabhethri e-lithium
Ngomkhuba wokuthuthuka we-miniaturization kanye nokusebenziseka kalula kwamathuluzi kagesi, amabhethri e-lithium asetshenziswa kabanzi kumathuluzi kagesi.Ukusetshenziswa kwamabhethri e-lithium kumathuluzi wamandla kukhule kusuka kuzintambo ezingu-3 kuya kuzintambo ezingu-6-10.Ukwanda kwenani lemikhiqizo eyodwa esetshenzisiwe kulethe ukwanda okukhulu.Amanye amathuluzi kagesi afakwe namabhethri ayisipele.
Mayelana namabhethri e-lithium asetshenziswa kumathuluzi kagesi, kusenokungaqondi kahle emakethe.Bakholelwa ukuthi ubuchwepheshe bebhethri lamandla ezimoto buphezulu, obuyinkimbinkimbi futhi obusezingeni eliphezulu.Eqinisweni, abanjalo.Amabhethri e-lithium asetshenziswa kumathuluzi kagesi adinga ukusetshenziswa ezindaweni eziphakeme kakhulu neziphansi., Futhi ukuzivumelanisa nokudlidliza okuqinile, ukushaja okusheshayo nokukhululwa okusheshayo, futhi idizayini yokuvikela ilula uma kuqhathaniswa, lezi zidingo azikho ngaphansi kunebhethri lamandla emoto, ngakho empeleni kuyinselele kakhulu ukwenza amabhethri asebenza kahle kakhulu, anezinga eliphezulu.Impela kungenxa yalezi zimo ezinzima ukuthi kwaze kwaba yiminyaka yamuva lapho izinhlobo ezinkulu zamathuluzi amandla omhlaba wonke zaqala ukusebenzisa amabhethri e-lithium asekhaya ngamaqoqo ngemva kweminyaka yokuqinisekiswa nokuqinisekiswa.Ngenxa yokuthi amathuluzi kagesi anezidingo eziphakeme kakhulu kumabhethri futhi nesigaba sokunikeza isitifiketi side kakhulu, iningi lazo alikangeni ochungechungeni lokuhlinzekwa kwezinkampani zamathuluzi kagesi ezinokuthunyelwa okukhulu kwamanye amazwe.
Nakuba amabhethri e-lithium anamathemba abanzi emakethe yamathuluzi kagesi, angcono kunamabhethri amandla ngokwenani (amaphesenti angu-10 aphezulu kunamabhethri amandla), inzuzo, nesivinini sokuthunyelwa kwemali, kodwa ama-giants amathuluzi wamazwe ngamazwe akhetha izinkampani zebhethri ye-lithium Zikhetha kakhulu, hhayi. idinga kuphela isikali esithile kumthamo wokukhiqiza, kodwa futhi idinga i-NCM811 ephezulu ye-nickel cylindrical kanye nezinqubo zokukhiqiza ze-NCA ezivuthiwe ngokwe-R&D namandla obuchwepheshe.Ngakho-ke, ezinkampanini ezifuna ukuguqula zibe ithuluzi lamandla emakethe yebhethri ye-lithium, ngaphandle kwezinqolobane zobuchwepheshe, kunzima ukungena ohlelweni lokuhlinzeka ngamatshe amathuluzi wamazwe ngamazwe.
Ngokuvamile, ngaphambi kuka-2025, ukusetshenziswa kwamabhethri e-lithium kumathuluzi wamandla kuzokhula ngokushesha.Noma ubani ongathatha lesi sigaba semakethe kuqala uzokwazi ukusinda ekuhlelweni kabusha okusheshisiwe kwezinkampani zebhethri lamandla.
Ngesikhathi esifanayo, ibhethri ye-lithium idinga ukuvikelwa okuhambisanayo.I-Neusoft Carrier yake yaletha ibhodi lokuvikela ibhethri le-lithium enkulumweni.Isizathu sokuthi kungani ibhethri ye-lithium idinga ukuvikelwa sinqunywa ukusebenza kwayo.Impahla yebhethri ye-lithium ngokwayo inquma ukuthi ayikwazi ukushajwa ngokweqile, ikhishwe ngokweqile, i-overcurrent, i-short circuited, futhi ikhishwe ekushiseni okuphezulu kakhulu.Ngaphezu kwalokho, amabhethri awanakho ukuvumelana okuphelele.Ngemuva kokuthi amabhethri enziwe abe izintambo, ukungafani kwamandla phakathi kwamabhethri kweqa umkhawulo othile, okuzophazamisa umthamo wangempela osebenzisekayo wephakethe lonke lebhethri.Ukuze senze lokhu, sidinga ukulinganisa amabhethri angafani.
Izici eziyinhloko zokungalingani kwephakethe lebhethri zivela ezicini ezintathu: 1. Ukukhiqizwa kwamaseli, iphutha lomthamo omncane (amandla wezinto zokusebenza, ukulawula ikhwalithi), 2. Iphutha lokufanisa ukuhlanganiswa kwamaseli (i-impedance, isimo se-SOC), 3. Iseli ngokwayo- ukukhishwa kwezinga elilinganayo [inqubo yeseli, ukuguqulwa kwe-impedance, inqubo yeqembu (ukulawula inqubo, ukuhlukanisa), indawo (inkambu eshisayo)].
Ngakho-ke, cishe yonke ibhethri ye-lithium kufanele ifakwe ibhodi lokuvikela ukuphepha, elakhiwe i-IC ezinikezele kanye nezingxenye ezimbalwa zangaphandle.Ingakwazi ukuqapha ngempumelelo futhi ivimbele ukulimala kwebhethri ngokusebenzisa iluphu yokuvikela, futhi ivimbele ukushiswa okubangelwa ukushajwa ngokweqile, ukukhishwa ngokweqile kanye nokujikeleza okufushane.Izingozi ezifana nokuqhuma.Njengoba ibhethri ngalinye le-lithium-ion kufanele lifake i-IC yokuvikela ibhethri, imakethe ye-IC yokuvikela ibhethri ye-lithium ikhula kancane kancane, futhi ithemba lemakethe libanzi kakhulu.
