Njengomthombo oyintloko wamandla kwizithuthi zamandla amatsha, iibhetri zamandla zibaluleke kakhulu kwizithuthi zamandla amatsha. Ngexesha lokusetyenziswa kwesithuthi, ibhetri iya kujongana neemeko zokusebenza ezinzima nezitshintshayo.
Kwiqondo lobushushu eliphantsi, ukumelana kwangaphakathi kweebhetri ze-lithium-ion kuya kwanda kwaye amandla aya kuncipha. Kwiimeko ezigqithisileyo, i-electrolyte iya kubanda kwaye ibhetri ayinakukhutshwa. Ukusebenza kobushushu obuphantsi kwenkqubo yebhetri kuya kuphazamiseka kakhulu, okubangela ukusebenza kwamandla okukhupha amandla ezithuthi zombane. Ukuncipha kobushushu kunye nobubanzi. Xa utshaja izithuthi zamandla amatsha phantsi kweemeko zobushushu obuphantsi, i-BMS eqhelekileyo iqala ifudumeze ibhetri kubushushu obufanelekileyo ngaphambi kokuba itshaje. Ukuba ayiphathwanga kakuhle, iya kukhokelela ekutshajisweni ngamandla oko nangoko, okubangela ukujikeleza okufutshane kwangaphakathi, kwaye umsi, umlilo okanye ukuqhuma kunokwenzeka.
Xa kushushu kakhulu, ukuba ulawulo lwetshaja aluphumeleli, lunokubangela ukusabela okunamandla kweekhemikhali ngaphakathi kwebhetri kwaye luvelise ubushushu obuninzi. Ukuba ubushushu buqokelelana ngokukhawuleza ngaphakathi kwebhetri ngaphandle kwexesha lokunyamalala, ibhetri inokuvuza, iphume igesi, umsi, njl. Kwiimeko ezinzima, ibhetri iya kutsha ngamandla ize iqhume.
Inkqubo yolawulo lobushushu bebhetri (iBattery Thermal Management System, BTMS) ngumsebenzi ophambili wenkqubo yolawulo lwebhetri. Ulawulo lobushushu bebhetri luquka ikakhulu imisebenzi yokupholisa, ukufudumeza kunye nokulinganisa ubushushu. Imisebenzi yokupholisa kunye nokufudumeza ihlengahlengiswa kakhulu ngokwempembelelo enokubakho yobushushu obungaphandle kwibhetri. Ukulinganisa ubushushu kusetyenziselwa ukunciphisa umahluko wobushushu ngaphakathi kwepakethi yebhetri kunye nokuthintela ukubola ngokukhawuleza okubangelwa kukushisa kakhulu kwenxalenye ethile yebhetri. Inkqubo yokulawula i-closed-loop yenziwe nge-heat-conducting medium, iyunithi yokulinganisa kunye nokulawula, kunye nezixhobo zokulawula ubushushu, ukuze ibhetri yamandla isebenze ngaphakathi koluhlu lobushushu olufanelekileyo ukugcina imeko yayo efanelekileyo yokusetyenziswa kunye nokuqinisekisa ukusebenza kunye nobomi benkqubo yebhetri.
1. Indlela yophuhliso lwemodeli "V" yenkqubo yolawulo lobushushu
Njengenxalenye yenkqubo yebhetri yamandla, inkqubo yolawulo lobushushu ikwaphuhliswa ngokuhambelana nemodeli yophuhliso lwemodeli ye-V" yoshishino lweemoto. Ngoncedo lwezixhobo zokulinganisa kunye nenani elikhulu lokuqinisekiswa kovavanyo, kuphela ngale ndlela apho ukusebenza kakuhle kophuhliso kunokuphuculwa, iindleko zophuhliso kunye nenkqubo yesiqinisekiso zinokugcinwa. Ukuthembeka, ukhuseleko kunye nobomi obude.
Oku kulandelayo yimodeli "V" yophuhliso lwenkqubo yolawulo lobushushu. Ngokubanzi, imodeli inee-axes ezimbini, enye ethe tye kunye nenye ethe nkqo: i-axis ethe tye yenziwe yimigca emine ephambili yophuhliso oluya phambili kunye nomgca oyintloko wokuqinisekiswa okungasemva, kwaye umgca oyintloko luphuhliso oluya phambili. , kuthathelwa ingqalelo ukuqinisekiswa okungasemva okuvaliweyo; i-axis ethe nkqo inamanqanaba amathathu: iinxalenye, iinkqubo ezingaphantsi kunye neenkqubo.
Ubushushu bebhetri buchaphazela ngokuthe ngqo ukhuseleko lwebhetri, ngoko ke uyilo kunye nophando lwenkqubo yolawulo lobushushu bebhetri ngomnye wemisebenzi ebalulekileyo kuyilo lwenkqubo yebhetri. Uyilo lolawulo lobushushu kunye nokuqinisekiswa kwenkqubo yebhetri kufuneka lwenziwe ngokuhambelana ngqo nenkqubo yoyilo lolawulo lobushushu bebhetri, inkqubo yolawulo lobushushu bebhetri kunye neentlobo zamacandelo, ukukhethwa kwamacandelo enkqubo yolawulo lobushushu, kunye novavanyo lokusebenza kwenkqubo yolawulo lobushushu. Ukuze kuqinisekiswe ukusebenza kunye nokhuseleko lwebhetri.
1. Iimfuno zenkqubo yolawulo lobushushu. Ngokweeparamitha zokufaka uyilo ezifana nendawo yokusetyenziswa kwesithuthi, iimeko zokusebenza kwesithuthi, kunye nefestile yobushushu yeseli yebhetri, yenza uhlalutyo lweemfuno ukuze kucaciswe iimfuno zenkqubo yebhetri kwinkqubo yolawulo lobushushu; iimfuneko zenkqubo, ngokutsho kohlalutyo lweemfuno, zimisela imisebenzi yenkqubo yolawulo lobushushu kunye neenjongo zoyilo lwenkqubo. Ezi njongo zoyilo ziquka ikakhulu ulawulo lobushushu beeseli zebhetri, umahluko wobushushu phakathi kweeseli zebhetri, ukusetyenziswa kwamandla enkqubo kunye neendleko.
2. Isakhelo senkqubo yolawulo lobushushu. Ngokweemfuno zenkqubo, inkqubo yahlulwe yaba yinkqubo engaphantsi kokupholisa, inkqubo engaphantsi kobushushu, inkqubo engaphantsi kobushushu kunye nenkqubo engaphantsi kobushushu ebalekayo (TRo), kwaye iimfuno zoyilo lwenkqubo nganye engaphantsi ziyachazwa. Kwangaxeshanye uhlalutyo lokulinganisa lwenziwa ukuqinisekisa uyilo lwenkqubo ekuqaleni. EzifanaIsifudumezi esipholileyo se-PTC, Isifudumezi somoya se-PTC, impompo yamanzi ye-elektroniki, njl. njl.
3. Uyilo lwenkqubo engaphantsi, kuqala kumiselwe injongo yoyilo lwenkqubo engaphantsi nganye ngokwendlela yoyilo lwenkqubo, kuze emva koko kwenziwe ukhetho lwendlela, uyilo lweskimu, uyilo oluneenkcukacha kunye nohlalutyo lokulinganisa kunye nokuqinisekiswa kwenkqubo engaphantsi nganye ngokulandelelana.
4. Uyilo lweendawo, kuqala lugqibe iinjongo zoyilo lweendawo ngokoyilo lwenkqubo engaphantsi, luze emva koko lwenze uhlalutyo oluneenkcukacha kunye novavanyo lokulinganisa.
5. Ukwenziwa nokuvavanywa kweenxalenye, ukwenziwa kweenxalenye, kunye nokuvavanywa nokuqinisekiswa.
6. Ukuhlanganiswa nokuqinisekiswa kwenkqubo engaphantsi, ukuhlanganiswa kwenkqubo engaphantsi kunye nokuqinisekiswa kovavanyo.
7. Ukuhlanganiswa kwenkqubo novavanyo, ukuhlanganiswa kwenkqubo nokuqinisekiswa kovavanyo.
