I-Audi Q6 e‑tron yimodeli yokuqala yemveliso kwiPPE. (Iposti yangaphambili.)
Iimoto. Onke amacandelo oqeqesho lwamandla e-PPE ayilelwe ukuba acutheke ngakumbi kuneenkqubo zokuqhuba eziphuhliswe zaza zafakwa ngaphambili, kwaye zibalasele ngenxa yokusebenza okuphezulu. Lilonke, imilinganiselo esebenzayo ejikeleze iinjini zombane ezintsha zePPE yenza ukuba iikhilomitha ezingama-40 zoluhlu olongezelelweyo xa kuthelekiswa nesizukulwana sokuqala se-Audi e-tron.
Kwindawo yokuvelisa, iqondo lokuzenzekelayo kunye noluhlu oluthe nkqo lwemveliso luye lwanda kakhulu. Iinjini zombane ezintsha zePPE zifuna malunga ne-30% indawo yofakelo engaphantsi kunezo zeemodeli zangaphambili zombane. Ubunzima babo buncitshiswe malunga ne-20%.
I-PSM (imagnethi esisigxina ye-synchronous motor) kwi-axle yangasemva ye-Audi Q6 e-tron series inobude be-200 millimeters. I-ASM (i-asynchronous motor) kwi-axle yangaphambili inobude be-100 millimeters. Xa ingasetyenziswa, iyakwazi ukujikeleza ngokukhululekileyo ngaphandle kwelahleko ebalulekileyo yokutsala.
I-hairpin entsha ejikajikayo kunye nenkqubo yokupholisa ngokuthe ngqo kwe-oyile-ye-oyile kwi-stator yemoto yombane inegalelo elikhulu ekusebenzeni okuphezulu kwenkqubo yokuqhuba. Ngokomzekelo, into yokuzalisa iye yanda ukuya kuma-60 ekhulwini xa kuthelekiswa neepesenti ze-45 kwii-windings eziqhelekileyo ezazisetyenziswa ngaphambili.
Impompo yeoli yombane ekuhanjisweni nayo inegalelo ekwandeni kokusebenza kakuhle. Ngenxa yokupholisa i-oyile ye-rotor, i-Audi nayo yakwazi ukukhupha ubukhulu becala kunye nokusetyenziswa kwezinto ezinzima ezinqabileyo zomhlaba ngelixa ngaxeshanye inyusa uxinano lwamandla ngama-20%.
Amandla ombane kunye nokuhanjiswa kwePPE. I-electronics yamandla (i-inverter) ilawula i-motor yombane kwaye ikwaguqula umsinga othe ngqo ukusuka kwibhetri ukuya kumbane otshintshayo. Idatha yolawulo oluchanekileyo lwe-inverter inikezelwa yi-domain yekhompyutheni ye-HCP1 (i-high-performance computing platform 1), ejongene nenkqubo yokuqhuba kunye nokumiswa.
I-Silicon carbide semiconductors ifakwe kwinguqu enamandla ngakumbi ye-inverter epholileyo yamanzi. Ngenxa yokusebenza kwabo kakuhle-60% ephezulu-bagqwesa ngokukodwa phantsi komthwalo oyingxenye kwaye banokwethenjelwa ngakumbi. Ngenxa yoko, banegalelo elikhulu ekusebenzeni kakuhle kunye nokusebenza okuphezulu kweenjini zombane zePPE. Inzuzo yoluhlu xa kuthelekiswa ne-silicon semiconductors malunga neekhilomitha ezingama-20.
Ngenxa yolwakhiwo lwe-800-volt, ucingo oluncinci lunokusetyenziswa kwakhona kwi-wiring yebhetri kunye nemoto yombane. Oku kunciphisa indawo yokufakela, ubunzima kunye nokusetyenziswa kwezinto eziluhlaza. Kuba isixokelelwano sishushu kancinci ngenxa yokulahleka kobushushu obuphantsi, inkqubo yokupholisa nayo incinci kwaye isebenza kakuhle. Ugqithiso lusebenza nge-sump lubrication eyomileyo kunye nepompo yeoli yombane. Imilomo yokutshiza iigiya ngokuthe ngqo. Olu luyilo lunciphisa ilahleko yokungqubana kwaye lunciphisa nendawo yofakelo.
Ukutshaja ukusebenza. I-architecture ye-800-volt, efunekayo kwimveliso yokutshaja ukuya kuma-270 kW, yenye yezinto eziphambili zokutshaja okuphezulu. I-cell chemistry iye yalungiswa ukuze ikwazi ukumelana nexabiso eliphezulu ngolo hlobo. I-Audi ithi ifumene ulungelelwaniso oluphezulu phakathi koxinano lwamandla kunye nokusebenza kokutshaja. Iiseli eziphuhliswe ngentsebenziswano kunye nomthengisi zibonelela ngoxinaniso lwamandla aphezulu, umxholo oncitshisiweyo wecobalt, kunye nokuchasana okuphantsi kowona msebenzi ubalaseleyo wokutshaja.
Ukongeza kwi-architecture ye-800-volt, ulawulo lwe-thermal oluhlakaniphile lunika igalelo elibalulekileyo ekusebenzeni okuphezulu kokutshaja kunye nobomi benkonzo ende yebhetri ye-HV kwi-PPE. Elona candelo libalulekileyo kulawulo lwe-thermal olubikezelwayo, olusebenzisa idatha esuka kwinkqubo yokukhangela, indlela, i-timer yokuhamba kunye nokuziphatha kokusetyenziswa komthengi ukubala imfuno yokupholisa okanye ukufudumeza kwangaphambili kunye nokubonelela kokubili ngokufanelekileyo nangexesha elifanelekileyo.
Ukuba umthengi uqhuba ukuhlawula kwisikhululo sokutshaja se-HPC esibandakanyiweyo kwisicwangciso sendlela, inkqubo yokulawula i-thermal eqikelelwayo iya kulungiselela inkqubo yokutshaja kwe-DC kwaye ipholile okanye ishushu ibhetri ukuze ihlawule ngokukhawuleza, ngaloo ndlela inciphisa ixesha lokutshaja. Ukuba kukho ukunyuka okuthe kratya ngaphambili, inkqubo yolawulo lobushushu iya kulungelelanisa ibhetri ye-HV ngokupholisa okufanelekileyo ukuthintela umthwalo ophezulu we-thermal. Ukuba umqhubi ukhethe imo esebenzayo kwimenyu yokukhetha i-drive, ukulungiswa kwebhetri kusebenze kamva kwaye uluhlu lwangempela lunokwandiswa ngokuxhomekeke kwindlela yokuziphatha yokuqhuba. Kwimo eguquguqukayo, injongo yintsebenzo efanelekileyo.
Nangona kunjalo, ukuba imeko yangoku ye-traffic ayikuvumeli ukuqhuba okuguquguqukayo, inkqubo yokulawula i-thermal iya kusabela kule nto kwaye inciphise ukusetyenziswa kwamandla kwi-battery conditioning.
Ukubekwa kweposi kunye nokuqhubekayo lolunye uphawu olutsha kwinkqubo yolawulo lobushushu lwePPE. Lo msebenzi ubeka iliso kwiqondo lokushisa kwebhetri kubomi benkonzo yonke ukugcina ibhetri kwinqanaba eliphezulu lobushushu nangona isithuthi simi-umzekelo, kubushushu obuphezulu kakhulu ngaphandle. Ukuqukuqela okupholisayo kuye kwaphuculwa ngokuphunyezwa komgaqo-nkqubo wokuhamba kwe-U ngaphantsi kweemodyuli zebhetri. Oku kukhokelela kwi-homogeneity ephezulu yobushushu ngaphakathi kwebhetri-ejongwa ngamaqondo obushushu angama-48-kwaye ekugqibeleni ukunikezelwa kwamandla aphezulu kunye nokusebenza kokufunxa.
Ngemeko yokuhlawula (i-SoC) malunga ne-10%, izithuthi kwi-series ye-e-tron ye-Audi Q6 zifuna nje imizuzu elishumi kwisikhululo sokutshaja ngokukhawuleza kumandla aphezulu wokutshaja we-270 kW kunye ne-DC etshaja ukuvelisa uluhlu olufikelela kwiikhilomitha ezingama-255 (iikhilomitha ezili-158) phantsi kweemeko ezifanelekileyo. Kuthatha imizuzu ye-21 ukuba ibhetri ye-HV ihlawuliswe ukusuka kwi-SoC yeepesenti ezilishumi ukuya kwi-80 ipesenti. Iyunithi yokulawula unxibelelwano, ebizwa ngokuba yi-Smart Actuator Charging Interface Device (SACID), isebenza njenge-interface yokuseka ikhonkco phakathi kwesokethi yokutshaja kunye nesikhululo sokutshaja kwaye idlulisele ulwazi oluqhelekileyo olungenayo kwikhompyutha yesizinda se-HCP5.
Ulawulo lobushushu bemoto. Inkqubo yokulawula ukushisa kwesithuthi iye yahlengahlengiswa. Ukuhlawulela ukunyuka kokusebenza kakuhle kwi-drivetrain kunye nokunciphisa okubangelwa ukulahleka kobushushu, ipompo yokushisa yamanzi-glycol yongezwa ngepompo yokushisa emoyeni. Oku kuthetha ukuba ukongeza kubushushu benkunkuma kwindawo yokupholisa yemoto yombane, ii-elektroniki zamandla, kunye nebhetri, umoya ojikelezayo unokusetyenziswa njengomthombo wokufudumeza ngaphakathi.
Utshintshiselwano lobushushu ngoku lusebenza ngokuthe ngqo ngekhoyili yokufudumeza. Ngaphezu koko, i-800-volt ye-heater ye-PTC yomoya yaphuhliswa njengongezelelo olusebenzayo, olukwaxhasa ngokuthe ngqo ulawulo lwangaphakathi lweqondo lokushisa kwiyunithi yomoya kwimeko yokunyuka kweemfuno zokufudumeza. Oku kuthintela ilahleko yobushushu ehambelana neesekethe zokufudumeza ezisekwe ngamanzi.
Ukuchacha kunye ne-friction brakes.Njengomthetho, kunye nePPE, malunga ne-95% yayo yonke inkqubo ye-braking yemihla ngemihla inokugqunywa ngokuchacha, oko kukuthi, ukunyathela ukuvuselela ngeenjini zombane. Ukusetyenziswa kweziqhoboshi ezingeyonyani ekuxubeni iziqhoboshi kwenzeka ngokuhambelanayo kamva okanye ngokunqabileyo. Kwi-PPE, umsebenzi wokubuyisela kwakhona awusayi kusingathwa yinkqubo yokulawula i-brake, kodwa kunoko yi-HCP1, enye yeekhomputha ezintlanu eziphezulu zokusebenza kwisithuthi, esijongene nenkqubo yokuqhuba kunye nokumiswa kwi-PPE. Ngenxa yoko, impembelelo yenkqubo ye-drive kwi-braking system iyanda.
Utshintsho olusuka kwiziqhoboshi ezihlaziyiweyo ngokudlula kwiisistim zokuqhuba zombane ukuya kwiziqhoboshi ezingoomatshini ngokudlula iziqhoboshi zokukhuhlana kwehydraulically akusabonakali kumqhubi. Ukudibanisa i-brake kuqinisekisa ukuba i-pedal elawulwa kakuhle ivakalelwa ngokucacileyo, igxininisekile yoxinzelelo.
I-Intelligent Brake System (IBS) eyaziwa kwiimodeli zangaphambili ze-e-tron iye yaphuhliswa ngakumbi kwi-Premium Platform Electric. Umzekelo, ukudibanisa i-axle-specific brake kuyenzeka okokuqala.
Ukuchacha kuhlala kwi-axle yangasemva njengoko kufuneka, ngelixa uxinzelelo lwehydraulic lwenziwa kwi-asi yangaphambili. Njengoko kuqhelekile kwi-Audi, kukho ukhetho lwenqanaba ezibini lokuphinda ubuyele elunxwemeni, olukhethekayo ngeepaddles kwivili lokuqhuba. Unxweme lunokwenzeka kwakhona. Apha i-SUV yombane iqengqeleka ngokukhululekileyo xa unyawo lususiwe kwi-accelerator, ngaphandle kokutsala okongeziweyo. Enye inketho kuthotho lwe-e-tron ye-Audi Q6 kukuqhuba imowudi "B," esondele kakhulu kwinto ebizwa ngokuba "yimvakalelo ye-pedal enye."
