Ulawulo lobushushu bebhetri
Ngexesha lenkqubo yokusebenza kwebhetri, ubushushu bunempembelelo enkulu ekusebenzeni kwayo.Ukuba iqondo lobushushu lisezantsi kakhulu, kunokubangela ukwehla okubukhali kumthamo webhetri kunye namandla, kunye nesekethi emfutshane yebhetri.Ukubaluleka kolawulo lobushushu bebhetri kuya kucaca ngakumbi njengoko ubushushu buphezulu kakhulu obunokubangela ukuba ibhetri ibole, idle, ibambe umlilo okanye ide igqabhuke.Ubushushu bokusebenza kwebhetri yamandla yinto ephambili ekumiseleni ukusebenza, ukhuseleko kunye nobomi bebhetri.Ukusuka kwindawo yokujonga ukusebenza, iqondo lokushisa eliphantsi kakhulu liya kukhokelela ekunciphiseni komsebenzi webhetri, okubangela ukuhla kwentlawulo kunye nokukhupha ukusebenza, kunye nokwehla okubukhali kumthamo webhetri.Uthelekiso lufumene ukuba xa izinga lokushisa liyehla ukuya kwi-10 ° C, umthamo wokukhutshwa kwebhetri wawuyi-93% yaloo bushushu obuqhelekileyo;nangona kunjalo, xa ubushushu behla ukuya kwi--20 ° C, umthamo wokukhupha ibhetri wawuyi-43% kuphela kwiqondo lokushisa eliqhelekileyo.
Uphando olwenziwa nguLi Junqiu nabanye bakhankanye ukuba ngokwembono yokhuseleko, ukuba iqondo lobushushu liphezulu kakhulu, ukusabela okusecaleni kwebhetri kuya kukhawuleziswa.Xa ubushushu busondele kwi-60 °C, izinto zangaphakathi / izinto ezisebenzayo zebhetri ziya kubola, kwaye emva koko "i-thermal runaway" iya kwenzeka, ibangele iqondo lobushushu Ukunyuka ngequbuliso, ukuya kuthi ga kwi-400 ~ 1000 ℃, kwaye emva koko kukhokelela umlilo kunye nokudubula.Ukuba iqondo lokushisa liphantsi kakhulu, izinga lokutshaja kwebhetri kufuneka ligcinwe kwizinga eliphantsi lokutshaja, ngaphandle koko liya kubangela ukuba ibhetri ichithe i-lithium kwaye ibangele isiphaluka esifutshane sangaphakathi ukubamba umlilo.
Ngokombono wobomi bebhetri, impembelelo yobushushu kubomi bebhetri ayinakungahoywa.Ukufakwa kweLithium kwiibhetri ezithanda ukutshaja ubushushu obuphantsi kuya kubangela ukuba ubomi bomjikelezo webhetri bubole ngokukhawuleza ukuya kumaxesha amaninzi, kwaye ubushushu obuphezulu buya kuchaphazela kakhulu ubomi bekhalenda kunye nobomi bomjikelezo webhetri.Uphando lufumene ukuba xa iqondo lokushisa liyi-23 ℃, ubomi bekhalenda yebhetri kunye ne-80% eseleyo umthamo malunga neentsuku ze-6238, kodwa xa iqondo lokushisa liphakama ukuya kuma-35 ℃, ubomi bekhalenda malunga neentsuku ze-1790, kwaye xa izinga lokushisa lifikelela kuma-55. ℃, ubomi bekhalenda bumalunga neentsuku ezingama-6238.Iintsuku ezingama-272 kuphela.
Okwangoku, ngenxa yeendleko kunye nezithintelo zobugcisa, ulawulo lobushushu bebhetri (I-BTMS) ayidityaniswanga ekusebenziseni i-media media, kwaye iyakwazi ukwahlula kwiindlela ezintathu eziphambili zobuchwepheshe: ukupholisa umoya (okusebenzayo kunye nokunyanzeliswa), ukupholisa ulwelo kunye nezinto zokutshintsha isigaba (PCM).Ukupholisa umoya kulula, akukho mngcipheko wokuvuza, kwaye kunoqoqosho.Ilungele ukuphuhliswa kokuqala kweebhetri ze-LFP kunye neendawo ezincinci zeemoto.Umphumo wokupholisa ulwelo ungcono kunowokupholisa umoya, kwaye iindleko zonyuswa.Xa kuthelekiswa nomoya, indawo yokupholisa ulwelo ineempawu zomthamo omkhulu wobushushu obuthile kunye ne-coefficient ephezulu yokudlulisa ubushushu, eyenza ngokufanelekileyo ukunqongophala kobugcisa bokusebenza kakuhle kokupholisa umoya.Lolona lungiselelo luphambili lweemoto zabakhweli ngoku.isicwangciso.UZhang Fubin wabonisa kuphando lwakhe ukuba inzuzo yokupholisa ulwelo kukutshatyalaliswa kobushushu obukhawulezayo, obunokuqinisekisa ubushushu obufanayo bepaki yebhetri, kwaye ifanelekile kwiipakethi zebhetri kunye nemveliso enkulu yokushisa;izinto ezingeloncedo ziindleko eziphezulu, iimfuno ezingqongqo zokupakisha, umngcipheko wokuvuza kolwelo, kunye nesakhiwo esintsonkothileyo.Izinto zokutshintsha isigaba zineenzuzo zokutshintshiselana kobushushu kunye neenzuzo zeendleko, kunye neendleko zokugcinwa okuphantsi.Itekhnoloji yangoku isekwinqanaba lelebhu.Itekhnoloji yolawulo lwe-thermal yezixhobo zokutshintsha kwesigaba ayikavuthwa ngokupheleleyo, kwaye sesona sikhokelo sophuhliso esinokubakho solawulo lobushushu bebhetri kwixesha elizayo.
Lilonke, ukupholisa ulwelo yeyona ndlela ikhoyo yetekhnoloji engundoqo, ikakhulu ngenxa yoku:
(1) Kwelinye icala, ibhetri ye-nickel ye-nickel ekhoyo ngoku inozinzo olubi ngakumbi kuneebhetri ze-lithium iron phosphate, iqondo lobushushu elisezantsi le-thermal ebalekayo (iqondo lobushushu lokubola, i-750 °C ye-lithium iron phosphate, 300 °C ye-ternary lithium iibhetri) , kunye nokuveliswa kobushushu obuphezulu.Kwelinye icala, iitekhnoloji entsha ye-lithium iron phosphate application efana nebhetri ye-BYD kunye nexesha le-Ningde CTP isusa iimodyuli, iphucula ukusetyenziswa kwendawo kunye noxinzelelo lwamandla, kwaye ikhuthaze ngakumbi ulawulo lobushushu bebhetri ukusuka kwitekhnoloji epholileyo yomoya ukuya kwitekhnoloji yolwelo olupholileyo.
(2) Ukuchatshazelwa yisikhokelo sokunciphisa inkxaso-mali kunye nokuxhalaba kwabathengi kuluhlu lokuqhuba, uluhlu lokuqhuba izithuthi zombane luyaqhubeka nokunyuka, kwaye iimfuno zoxinano lwamandla ebhetri luya phezulu nangaphezulu.Ibango letekhnoloji yokupholisa ulwelo kunye nokuhanjiswa kobushushu okuphezulu konyukile.
(3) Iimodeli ziphuhliswa kwicala leemodeli ze-middle-to-high-end, kunye nohlahlo lwabiwo-mali olwaneleyo, ukuphishekela induduzo, ukunyamezela kwecala eliphantsi kunye nokusebenza okuphezulu, kunye nesisombululo sokupholisa ulwelo sihambelana ngakumbi neemfuno.
Nokuba yimoto yemveli okanye isithuthi samandla esitsha, imfuno yabathengi yokuthuthuzela iya inyuka ngokunyuka, kwaye itekhnoloji yolawulo lwe-cockpit ibaluleke kakhulu.Ngokubhekiselele kwiindlela zokukhenkcisa, iicompressor zombane zisetyenziswa endaweni yecompressor eziqhelekileyo zokufakwa efrijini, kwaye iibhetri zihlala ziqhagamshelwa kwiinkqubo zokupholisa umoya.Izithuthi zemveli ubukhulu becala zamkela uhlobo lwepleyiti yokuswasha, ngelixa iimoto zamandla amatsha ikakhulu zisebenzisa uhlobo lwe-vortex.Le ndlela inokusebenza okuphezulu, ubunzima obulula, ingxolo ephantsi, kwaye iyahambelana kakhulu namandla okuqhuba umbane.Ukongezelela, isakhiwo silula, ukusebenza kuzinzile, kwaye ukusebenza kwe-volumetric yi-60% ephezulu kunohlobo lwe-swash plate.% malunga.Ngokwendlela yokufudumeza, ukufudumeza kwePTC(Isifudumezi somoya se-PTC/Isifudumezi esipholisayo se-PTC) iyafuneka, kwaye izithuthi zombane azinayo imithombo yobushushu exabisa i-zero (efana ne-injini yokutshisa yangaphakathi yokupholisa)
