1.IiMfuno zoLawulo lweSithuthi soMbane (HVCH)
Indawo yabakhweli yindawo yokusingqongileyo apho umqhubi ahlala khona ngelixa isithuthi siqhuba.Ukuze kuqinisekiswe indawo yokuqhuba ekhululekileyo kumqhubi, ulawulo lwe-thermal lwendawo yabakhweli lufuna ukulawula ubushushu, ukufuma, kunye nobushushu bokubonelela ngomoya kwindawo yangaphakathi yesithuthi.Iimfuno zolawulo lwe-thermal yendawo yabagibeli phantsi kweemeko ezahlukeneyo ziboniswa kwiThebhile 1.
Ulawulo lobushushu bebhetri yamandla luyimfuneko ebalulekileyo yokuqinisekisa ukusebenza ngokufanelekileyo nangokukhuselekileyo kwezithuthi zombane.Xa iqondo lobushushu liphezulu kakhulu, liya kubangela ukuvuza kolwelo kunye nokutsha okuzenzekelayo, okuya kuchaphazela ukhuseleko lokuqhuba;xa iqondo lobushushu liphantsi kakhulu, intlawulo yebhetri kunye nomthamo wokukhupha uya kuthotywa ukuya kumlinganiselo othile.Ngenxa yobuninzi bamandla kunye nobunzima obulula, iibhetri ze-lithium ziye zaba zezona bhetri zamandla ezisetyenziswa kakhulu kwiimoto zombane.Iimfuno zokulawula ubushushu beebhetri ze-lithium kunye nomthwalo wobushushu bebhetri phantsi kweemeko ezahlukeneyo eziqikelelwa ngokweencwadi ziboniswa kwiThebhile 2. Ngokunyuka ngokuthe ngcembe kubuninzi bamandla ebhetri yamandla, ukwandiswa koluhlu lweqondo lokushisa kwindawo yokusebenza, kunye ukwanda kwezantya zokutshaja ngokukhawuleza, ukubaluleka kokulawula ubushushu bebhetri yamandla kwinkqubo yolawulo lwe-thermal kuye kwabonakala ngakumbi, kungekhona nje ukuhlangabezana neemeko zendlela ezahlukeneyo kunye neendlela ezahlukeneyo zokutshaja kunye nokukhupha.Umthwalo wokulawula ubushushu utshintsha phantsi kweemeko zokusebenza kwesithuthi, ukufana kwebala lobushushu phakathi kweepakethi zebhetri kunye nokuthintela kunye nokulawulwa kwe-thermal runaway nayo kufuneka ihlangabezane nazo zonke iimfuno zokulawula ubushushu phantsi kweemeko ezahlukeneyo zokusingqongileyo ezifana nokubanda okukhulu, okuphezulu. iindawo zobushushu kunye nokufuma okuphezulu, kunye neendawo ezishushu zasehlotyeni kunye neendawo ezibandayo zasebusika.isidingo.
2. Inqanaba lokuqala lokufudumeza kwe-PTC
Kwinqanaba lokuqala loshishino lweemoto zombane, iteknoloji engundoqo isekelwe ekutshintshweni kweebhetri, iimoto kunye nezinye iinkqubo zamandla.ngokusekelwe kuphuculo oluthe chu.I-air conditioner yemoto yombane ecocekileyo kunye ne-air conditioner yesithuthi samafutha zombini ziyawuqonda umsebenzi wefriji ngokusebenzisa umjikelo woxinzelelo lomphunga.Umahluko phakathi kwezi zibini kukuba i-compressor ye-air conditioner yesithuthi samafutha iqhutywe ngokungathanga ngqo yi-injini ngebhanti, ngelixa isithuthi sombane esicocekileyo sisebenzisa ngokuthe ngqo i-compressor yombane yokuqhuba ifriji.umjikelo.Xa izithuthi zamafutha zifudunyezwa ebusika, inkunkuma yobushushu be-injini isetyenziselwa ngokuthe ngqo ukufudumeza indawo yabahambi ngaphandle komthombo wobushushu owongezelelweyo.Nangona kunjalo, ukushisa kwenkunkuma yemoto yeemoto zombane ezicocekileyo azikwazi ukuhlangabezana neemfuno zokufudumeza ebusika.Ngoko ke, ukufudumeza ebusika kuyingxaki ukuba izithuthi zombane ezicocekileyo kufuneka zisonjululwe..Isifudumezi esifanelekileyo somlinganiso wobushushu (i-coefficient yobushushu obufanelekileyo, i-PTC) yenziwe nge-PTC ceramic element yokufudumeza kunye netyhubhu yealuminiyam (Isifudumezi esipholileyo se-PTC/Isifudumezi somoya se-PTC), enezibonelelo zokuxhathisa ubushushu obuncinci kunye nokusebenza kakuhle kokudluliselwa kobushushu, kwaye isetyenziswa kwisiseko somzimba wezithuthi zamafutha Ke ngoko, izithuthi zombane zangaphambili zasebenzisa umphunga wokunyanzeliswa komjikelo wefriji yefriji kunye nokufudumeza kwe-PTC ukufikelela kulawulo lobushushu kwindawo yabakhweli.
2.1 Ukusetyenziswa kweteknoloji yempompo yokushisa kwinqanaba lesibini
Ekusetyenzisweni kwangempela, izithuthi zombane zinemfuno ephezulu yokufudumeza ukusetyenziswa kwamandla ebusika.Ukusuka kwimbono ye-thermodynamic, i-COP ye-PTC yokufudumeza ihlala ingaphantsi kwe-1, eyenza ukusetyenziswa kwamandla okushisa kwe-PTC kuphezulu kwaye izinga lokusetyenziswa kwamandla liphantsi, elithintela kakhulu izithuthi zombane.mileage.Itekhnoloji yempompo yobushushu isebenzisa umjikelo wokunyanzeliswa komphunga ukusebenzisa ubushushu obuphantsi kwindalo esingqongileyo, kunye neCOP yethiyori ngexesha lokufudumeza likhulu kune-1. Ngoko ke, ukusebenzisa inkqubo yempompo yobushushu endaweni ye-PTC kunokunyusa uluhlu lokuhamba ngeenqwelo zombane eziphantsi kobushushu. iimeko.Ngokuphuculwa ngakumbi komthamo kunye namandla ebhetri yamandla, umthwalo we-thermal ngexesha lokusebenza kwebhetri yamandla nawo ukhula ngokuthe ngcembe.Isakhiwo esiqhelekileyo sokupholisa umoya asikwazi ukuhlangabezana neemfuno zokulawula ubushushu bebhetri yamandla.Ke ngoko, ukupholisa ulwelo kube yeyona ndlela iphambili yolawulo lobushushu bebhetri.Ngaphezu koko, ekubeni ubushushu obutofotofo obufunwa ngumzimba womntu bufana neqondo lobushushu apho ibhetri yamandla isebenza ngokuqhelekileyo, iimfuno zokupholisa zegumbi labahambi kunye nebhetri yamandla zinokuhlangatyezwa ngokuqhagamshela abatshintshi bobushushu ngokunxuseneyo kwimpompo yobushushu yendawo yabahambi. inkqubo.Ukushisa kwebhetri yamandla kuthathwa ngokungathanga ngqo ngumtshintshi wokushisa kunye nokupholisa okwesibini, kwaye idigri yokudibanisa yenkqubo yokulawula i-thermal yemoto yombane iphuculwe.Nangona iqondo lokudityaniswa liphuculwe, inkqubo yolawulo lwe-thermal kweli nqanaba idibanisa kuphela ukupholisa kwebhetri kunye negumbi labahambi, kwaye ubushushu benkunkuma yebhetri kunye nemoto ayizange isetyenziswe ngokufanelekileyo.
