I-EV Lithium Amabhethri Inezimfuneko Zokusebenza Ezikhawulelwe Ezengeziwe
Ngenxa yomkhawulo wosayizi nesisindo semoto kanye nezidingo zokuqalisa ukusheshisa, amabhethri e-EV anezidingo zokusebenza eziphakeme kunamabhethri ajwayelekile okugcina amandla.Isibonelo, ukuminyana kwamandla kufanele kube phezulu ngangokunokwenzeka, isivinini sokushaja sebhethri kufanele sisheshe, futhi umsinga wokuphuma kufanele ube mkhulu.Izidingo zamabhethri okugcina amandla aziphezulu kangako.Ngokwezindinganiso, amabhethri e-EV anamandla angaphansi kuka-80% awasakwazi ukusetshenziswa ezimotweni zamandla amasha, kodwa angasetshenziswa ezinhlelweni zokugcina amandla ngokuguqulwa okuncane.
Umehluko Wezimo Zokusebenza
Ngokombono wezimo zohlelo lokusebenza, amabhethri e-EV lithium asetshenziswa kakhulu ezimotweni zikagesi, amabhayisikili kagesi namanye amathuluzi kagesi, kuyilapho amabhethri e-lithium yokugcina amandla asetshenziswa kakhulu ezinsizakalweni zosizo zamandla aphezulu kanye nemvamisa, amandla avuselelekayo axhumeke kugridi kanye negridi encane. amasimu.
Amabhethri e-EV Lithium anomthamo Ophakeme Wamandla
Ngenxa yezimo ezihlukene zohlelo lokusebenza, izidingo zokusebenza kwebhethri nazo zihlukile.Okokuqala, njengomthombo wamandla weselula, ibhethri ye-lithium ye-EV inemfuneko ephezulu ngangokunokwenzeka kumthamo wamandla wevolumu (kanye nobuningi) ngaphansi kwesisekelo sokuphepha, ukuze kuzuzwe ukukhuthazela okude.Ngesikhathi esifanayo, abasebenzisi banethemba lokuthi izimoto zikagesi zingashajwa ngokuphepha futhi ngokushesha.Ngakho-ke, amabhethri e-lithium e-EV anezidingo eziphakeme zokuminyana kwamandla kanye nokuminyana kwamandla.Kungenxa nje yokucatshangelwa kwezokuphepha ukuthi amabhethri ohlobo lwamandla aneshaja namandla okuphuma acishe abe ngu-1C avame ukusetshenziswa.
Imishini eminingi yokugcina amandla imile, ngakho-ke amabhethri e-lithium okugcina amandla awanazo izidingo eziqondile zokuminyana kwamandla.Ngokuqondene nokuminyana kwamandla, izimo zesitoreji samandla ezihlukene zinezidingo ezihlukile.
Ngokuvamile, ibhethri yesitoreji samandla idinga ukushajwa ngokuqhubekayo noma ukushajwa ngokuqhubekayo isikhathi esingaphezu kwamahora amabili ngokushefa okuphezulu kwamandla, isitoreji samandla e-photovoltaic ngaphandle kwegridi, noma izimo zokulondoloza amandla ukusuka phezulu ukuya esigodini ohlangothini lomsebenzisi.Ngakho-ke kufanelekile ukusebenzisa uhlobo lomthamo ngenani lokushaja ≤0.5C ibhethri;Ezimeni zesitoreji samandla lapho kudingeka khona ukushintshashintsha kwefrikhwensi yamandla noma ukushintshashintsha kwamandla avuselelekayo abushelelezi, ibhethri lesitoreji samandla lidinga ukushajwa ngokushesha futhi lishajwe esikhathini sesibili ukuya kuminithi, ngakho lifanele izinhlelo zokusebenza ezinamabhethri anamandla angu-≥2C;futhi kwezinye izimo, idinga ukwenza i-frequency modulation Ezimweni zohlelo lokusebenza lokushefa okuphezulu, amabhethri ohlobo lwamandla afaneleka kakhulu.Kunjalo, amabhethri ohlobo lwamandla kanye nohlobo lomthamo angasetshenziswa ndawonye kulesi simo.
Ibhethri Lesitoreji Samandla Linokuphila Kwesevisi Okude
Uma kuqhathaniswa namandla amabhethri e-lithium, ukugcina amandla amabhethri e-lithium anezidingo eziphakeme zempilo yesevisi.Ukuphila kwezimoto ezintsha zamandla ngokuvamile kuyiminyaka emi-5-8, kuyilapho ukuphila kwamaphrojekthi okugcina amandla ngokuvamile kulindeleke ukuba kube ngaphezulu kweminyaka eyi-10.Impilo yomjikelezo webhethri ye-lithium yamandla izikhathi eziyi-1000-2000, futhi impilo yomjikelezo webhethri ye-lithium yokugcina amandla ngokuvamile idingeka ukuthi ibe nkulu kunezikhathi ze-5000.
Izindleko Zebhethri Lesitoreji Samandla Ziphansi
Mayelana nezindleko, amabhethri e-EV abhekana nokuncintisana nemithombo yamandla kaphethiloli evamile, kuyilapho amabhethri e-lithium esitoreji samandla adinga ukubhekana nokuncintisana kwezindleko kusukela kubuchwepheshe bokushintshaniswa kwemvamisa okuphezulu okuphezulu kanye nokulinganisa imvamisa.Ukwengeza, isikali seziteshi zamandla okugcina amandla ngokuyisisekelo singaphezu kwezinga le-megawatt noma ngisho namamegawathi ayi-100.Ngakho-ke, izindleko zokugcina amandla amabhethri e-lithium aphansi kunalawo amabhethri e-lithium yamandla, futhi izidingo zokuphepha nazo ziphakeme.
Kukhona omunye umehluko phakathi kwamabhethri e-lithium e-EV kanye namabhethri e-lithium okugcina amandla, kodwa ngokombono wamaseli, ayafana.Womabili amabhethri e-lithium iron phosphate namabhethri e-ternary lithium angasetshenziswa.Umehluko omkhulu ulele ohlelweni lokuphatha ibhethri le-BMS kanye nesivinini sokuphendula amandla ebhethri.Futhi izici zamandla, ukunemba kokulinganisa kwe-SOC, izici zokushaja nokukhipha, njll., konke kungenziwa ku-BMS.
