Njengowona mthombo wamandla wezithuthi ezitsha zamandla, iibhetri zamandla zibaluleke kakhulu kwizithuthi zamandla amatsha.Ngexesha lokusetyenziswa kwesithuthi, ibhetri iya kujongana neemeko zokusebenza ezinzima kunye neziguquguqukayo.
Kwiqondo lokushisa eliphantsi, ukuchasana kwangaphakathi kweebhetri ze-lithium-ion kuya kwanda kwaye umthamo uya kuncipha.Kwiimeko ezigqithisileyo, i-electrolyte iya kuba ngumkhenkce kwaye ibhetri ayinakukhutshelwa.Ukusebenza okuphantsi kweqondo lokushisa kwenkqubo yebhetri kuya kuchaphazeleka kakhulu, kubangele ukusebenza kombane wezithuthi zombane.Ukuphela kunye nokunciphisa uluhlu.Xa utshaja iimoto zamandla amatsha phantsi kweemeko zobushushu obuphantsi, i-BMS ngokubanzi iqala ngokufudumeza ibhetri kwiqondo lobushushu elifanelekileyo phambi kokutshaja.Ukuba ayiphathwa ngokufanelekileyo, iya kukhokelela ekutshajisweni kwamandla ombane ngoko nangoko, okukhokelela kumjikelezo omfutshane wangaphakathi, kunye nomsi ongaphaya, umlilo okanye uqhushumbo.
Kubushushu obuphezulu, ukuba ulawulo lwetshaja aluphumeleli, lunokubangela ukusabela kweekhemikhali ezinobundlobongela ngaphakathi ebhetrini kwaye kuvelise ubushushu obuninzi.Ukuba ubushushu buqokelelana ngokukhawuleza ngaphakathi kwebhetri ngaphandle kwexesha lokutshabalala, ibhetri inokuvuza, ikhuphe umoya, umsi, njl njl. Kwiimeko ezinzima, ibhetri iya kutshisa ngamandla kwaye iqhume.
Inkqubo yokulawula ibhetri ye-thermal (i-Battery Thermal Management System, i-BTMS) ngumsebenzi oyintloko wenkqubo yokulawula ibhetri.Ulawulo lwe-thermal yebhetri ikakhulu lubandakanya imisebenzi yokupholisa, ukufudumeza kunye nokulinganisa ubushushu.Imisebenzi yokupholisa kunye nokufudumeza ilungiswa ikakhulu ngenxa yempembelelo enokwenzeka yobushushu be-ambient yangaphandle kwibhetri.Ukulinganisa ubushushu kusetyenziswa ukunciphisa umahluko wobushushu ngaphakathi kwipakethi yebhetri kwaye kuthintelwe ukubola okukhawulezileyo okubangelwa kubushushu obugqithisileyo bendawo ethile yebhetri.Inkqubo yokulawula i-loop evaliweyo iqulunqwe ngumgangatho oqhuba ubushushu, iyunithi yokulinganisa kunye nokulawula, kunye nezixhobo zokulawula ubushushu, ukuze ibhetri yamandla ikwazi ukusebenza ngaphakathi komgangatho ofanelekileyo wokushisa ukugcina imeko yokusetyenziswa kakuhle kunye nokuqinisekisa ukusebenza kunye nobomi bebhetri. inkqubo yebhetri.
1. "V" imodeli yophuhliso lwenkqubo yolawulo lwe-thermal
Njengenxalenye yenkqubo yebhetri yamandla, inkqubo yokulawula i-thermal nayo iphuhliswe ngokuhambelana ne-V "imodeli yokuphuhlisa imodeli yoshishino lweemoto. uphuhliso olusebenzayo luphuculwe, iindleko zophuhliso kunye nenkqubo yesiqinisekiso zigcinwe Ukuthembeka, ukhuseleko kunye nokuphila ixesha elide.
Oku kulandelayo ngumzekelo "V" wophuhliso lwenkqubo yolawulo lwe-thermal.Ngokuqhelekileyo, imodeli iqulethe i-axes ezimbini, enye i-horizontal kunye ne-vertical enye: i-axis ethe tyaba iqulunqwe yimizila emine yophuhliso lwangaphambili kunye nomgca omnye oyintloko wokuqinisekisa umva, kwaye umgca oyintloko kuphuhliso lwangaphambili., kuthathela ingqalelo umva wokuqinisekiswa kwe-loop evaliweyo;i-axis ethe nkqo inamanqanaba amathathu: amacandelo, ii-subsystems kunye neenkqubo.
Ubushushu bebhetri buchaphazela ngqo ukhuseleko lwebhetri, ngoko ke uyilo kunye nophando lwenkqubo yolawulo lwe-thermal yebhetri yenye yeyona misebenzi ibalulekileyo kuyilo lwenkqubo yebhetri.Uyilo lolawulo lwe-thermal kunye nokuqinisekiswa kwenkqubo yebhetri kufuneka luqhutywe ngokuhambelana ngqongqo nenkqubo yoyilo lolawulo lwe-thermal, inkqubo yolawulo lwe-thermal yebhetri kunye neentlobo zecandelo, ukhetho lwecandelo lolawulo lwe-thermal, kunye novavanyo lwenkqubo yolawulo lwe-thermal.Ukuze uqinisekise ukusebenza kunye nokhuseleko lwebhetri.
1. Iimfuno zenkqubo yokulawula i-thermal.Ngokweeparamitha zegalelo loyilo ezifana nendawo yokusetyenziswa kwesithuthi, iimeko zokusebenza zesithuthi, kunye nefestile yeqondo lokushisa kwiseli yebhetri, yenza uhlalutyo lweemfuno ukucacisa iimfuno zenkqubo yebhetri yenkqubo yokulawula i-thermal;iimfuno inkqubo, ngokweeMfuno uhlalutyo imisela imisebenzi yenkqubo yolawulo thermal kunye neenjongo zoyilo lwenkqubo.Ezi njongo zoyilo ikakhulu zibandakanya ulawulo lobushushu beeseli zebhetri, umahluko wobushushu phakathi kweeseli zebhetri, ukusetyenziswa kwamandla enkqubo kunye neendleko.
2. Inkqubo yolawulo lwe-thermal.Ngokweemfuno zenkqubo, inkqubo yohlulwe ibe yinkqubo ephantsi yokupholisa, isixokelelwano esisezantsi sokufudumeza, isistim yokufakelwa kwe-thermal kunye ne-thermal runaway obstructin (Tro) inkqubo engaphantsi, kunye neemfuno zoyilo zenkqubo engaphantsi nganye zichaziwe.Ngexesha elifanayo uhlalutyo lokulinganisa luqhutyelwa ekuqaleni ukuqinisekisa ukuyila kwenkqubo.NjengeIsifudumezi esipholileyo se-PTC, Isifudumezi somoya se-PTC, impompo yamanzi ye-elektroniki, njl.
3. Uyilo lwenkqubo engaphantsi, kuqala misela injongo yoyilo lwesistim engaphantsi nganye ngokoyilo lwesistim, kwaye emva koko uphumeze ukhetho lwendlela, uyilo lwesikimu, uyilo oluneenkcukacha kunye nohlalutyo lokulinganisa kunye nokuqinisekiswa kwenkqubo engaphantsi nganye ngokulandelelana.
4. Uyilo lwamacandelo, okokuqala misela iinjongo zoyilo lwamalungu ngokwenkqubo engaphantsi koyilo, kwaye emva koko uphumeze uyilo oluneenkcukacha kunye nohlalutyo lokulinganisa.
5. Ukwenziwa kunye novavanyo lwamalungu, ukwenziwa kwamalungu, kunye novavanyo kunye nokuqinisekiswa.
6. Ukudityaniswa kwe-subsystem kunye nokuqinisekiswa, ukuhlanganiswa kwe-subsystem kunye nokuqinisekiswa kovavanyo.
7. Ukuhlanganiswa kwenkqubo kunye nokuvavanya, ukudibanisa inkqubo kunye nokuqinisekiswa kokuvavanya.
