Yintoni iyunithi yokusasaza amandla aphezulu kwiimoto
Iyunithi yokusasazwa kwe-high-voltage yeemoto (i-PDU) yinxalenye ebalulekileyo kwinkqubo ye-high-voltage yezithuthi ezintsha zamandla, enoxanduva olukhulu lokusasazwa kwamandla kunye nolawulo ukuqinisekisa ukusebenza ngokukhuselekileyo nangokuzinzileyo kwezixhobo ze-high-voltage zesithuthi.
Imisebenzi ephambili
I-Youdaoplaceholder0 Ukusasazwa nokulawulwa kwamandla: Ukusasazwa ngokukhuselekileyo kombane ohamba ngqo we-high-voltage kwizixhobo ezahlukeneyo zombane, ezinje ngee-drive motors, iinkqubo zokutshaja, njl.
Ulawulo lokutshaja kunye nokukhupha i-Youdaoplaceholder0: Ulawula inkqubo yokutshaja kunye nokukhupha i-system ye-high-voltage, kubandakanya ukhuseleko lokugqithisela, ukhuseleko lwe-short-circuit kunye nomsebenzi wokuthatha isampuli ye-high-voltage.
Ulawulo lwe-Youdaoplaceholder0 olune-voltage ephantsi : ulawulo lokuvula amandla kunye nokubeka iliso kwimeko yezinto ezine-voltage ephezulu ngokusebenzisa iisekethe ezine-voltage ephantsi.
Uyilo lokusasaza ubushushu lwe-Youdaoplaceholder0 : Ezinye ii-PDU zamkela izakhiwo zokupholisa amanzi okanye zokupholisa umoya ukuqinisekisa iimfuno zokusasaza ubushushu kwiindawo ezine-voltage ephezulu.
Iimpawu zesakhiwo
I-PDU inokudibanisa imisebenzi efana neemodyuli zokuguqula ze-DC-DC, iimodyuli ze-OBC zokutshaja, kunye nolawulo oluphambili lwe-BMS, nto leyo efezekisa uyilo oludibeneyo kakhulu. Umzekelo, iimodyuli ezintathu-kwinye kunye nezine-kwinye zinokudibanisa iiyunithi ezininzi ezisebenzayo ukuhlangabezana neemfuno zeemodeli ezahlukeneyo zezithuthi.
Iyunithi yokusasazwa kwamandla aphezulu eemoto (iPDU) sisixhobo solawulo esiphambili senkqubo yombane ophezulu kwizithuthi ezintsha zamandla, ikakhulu efezekisa imisebenzi yokusasazwa kwamandla kunye nokhuseleko. Nazi ezi zilandelayo imisebenzi yayo ephambili:
Ukusasazwa kwamandla ombane aphezulu
I-PDU isasaza i-high-voltage direct current (300-800V) output yibhetri yamandla kwiindawo eziphambili ezifana ne-drive motor, i-on-board charger (OBC), i-DC/DC converter, kunye ne-electric air conditioning compressor. Umzekelo, i-drive motor controller ithatha malunga ne-60% ye-electrical output, kwaye enye ishiyelwe kwiinkqubo ezincedisayo ezifana nokutshaja kunye nokufudumeza.
Indlela yokukhusela ukhuseleko
Kubandakanya ukhuseleko olugqithisileyo, umjikelo omfutshane, ukhuseleko olugqithisileyo kunye nobushushu obugqithisileyo:
Ukhuseleko lwe-Youdaoplaceholder0 overcurrent : Xa i-current idlula i-120% yexabiso elilinganisiweyo kwimizuzwana emi-2, i-contactor ephambili iyasuswa kwaye i-fuse iyavuthelwa
Ukhuseleko lwe-Youdaoplaceholder0 Short-circuit : Xa i-impedance ingaphantsi kwe-100mΩ, i-circuit iyanqanyulwa kwi-microseconds
Ukhuseleko lobushushu obugqithisileyo lwe-Youdaoplaceholder0: Xa ubushushu be-copper budlula i-110℃, buya kunciphisa umthwalo kancinci kancinci okanye bunqumle amandla
Ukufunyanwa kwe-insulation ye-Youdaoplaceholder0 : inokuchonga umngcipheko wokungasebenzi kakuhle kwe-insulation <500Ω/V kwaye ibangele i-alamu
Ukuhlanganiswa nolawulo lwenkqubo
Idibanisa imodyuli yokuguqula i-DC/DC, iyunithi yokulawula ukutshaja kunye nomsebenzi wolawulo oluphambili lwe-BMS, kwaye ixhasa uyilo lwemodyuli. Imiyalelo ye-VCU ifunyanwa ngebhasi ye-CAN ukuze kufezekiswe ulawulo lwesequence yokuvula/yokucima umbane yesekethe ye-voltage ephezulu (ixesha lokuphendula <50ms), kwaye icebo lokusasazwa kwamandla liyalungiswa ngokuguquguqukayo (njengokubeka phambili ukuvalwa kwemithwalo engeyomfuneko ngexesha lokutshaja).
Izalathi zokusebenza
Ukusebenza kakuhle kokusasazwa ≥98% (umthwalo ongaphantsi komlinganiselo)
Amandla okukhusela angamelana ne-2500V AC imizuzwana engama-60 ngaphandle kokuphazamiseka
Ubomi boomatshini be-relay ye-high-voltage bungaphezulu kwe-100,000 cycles
Ixhasa umsebenzi wokufanisa umthwalo ohambelanayo (ukunciphisa ukusetyenziswa kwamandla nge-5-8%)
Iziphene kwiyunithi yokusasazwa kwamandla aphezulu kwisithuthi zihlala zikhokelela kwiinkqubo zamandla ezingaqhelekanga, ukuphazamiseka kokutshaja okanye umonakalo kwizixhobo zombane, ezibonakaliswa ngokukodwa ngolu hlobo:
Ingxaki yento
Ukusilela kwenkqubo yamandla ye-Youdaoplaceholder0: Isithuthi asikwazi ukukhawulezisa ngokwesiqhelo, kwaye isantya esiphezulu sinqunyelwe (umzekelo, isantya kwimeko yi-40km/h kuphela)
I-Youdaoplaceholder0 Ukutshaja okungaqhelekanga : Ukutshaja kwe-AC/DC kuphazamisekile okanye akunakuqalwa (jonga iimpazamo kumgca wesixhobo sokutshaja okanye isenzi)
I-alamu yesixhobo se-Youdaoplaceholder0: Ibonisa "impazamo yenkqubo yombane ophezulu" okanye "impazamo yenkqubo yamandla"
Ukhuseleko lwenxalenye yombane ye-Youdaoplaceholder0: Inkqubo inqumla ngokuzenzekelayo isekethe ye-high-voltage ukuthintela umonakalo ongakumbi (ezifana nabalawuli beemoto, iibhetri zamandla, njl.njl.)
Izizathu eziqhelekileyo
Isekethe ye-Youdaoplaceholder0 ene-voltage ephezulu ye-interlock circuit evulekileyo : imiqondiso yokujonga engaqhelekanga ibangela ukutshixeka kwenkqubo (njengokunxibelelana kakubi komgca, ukukhubeka kwe-circuit breaker)
Iziphene zangaphakathi zebhokisi yokusasaza: i-contactor yebhokisi yokusasaza ene-voltage ephezulu iyabambeka, kwaye ukufunyanwa kokuvuza kuyasilela
I-Youdaoplaceholder0 I-short circuit okanye i-overload : umonakalo kumaleko we-insulation we-high-voltage wiring harness ubangela i-short circuit emhlabeni
Iindlela zokuxilonga
I-Youdaoplaceholder0 Funda ikhowudi yempazamo : Fumana ikhowudi yempazamo ethile (efana ne-P1E0300, B042900) nge-decoder
Uvavanyo lwe-waveform yesignali ye-Youdaoplaceholder0 : Jonga ukuba isignali yomjikelo womsebenzi wesekethe ye-interlock ye-high-voltage iqhelekile na (kufuneka izixhobo zobungcali)
Ukuqinisekiswa kovavanyo lwesekethe ye-Youdaoplaceholder0 : Jonga impendulo yezixhobo zombane (ezifana nemeko yokunikezelwa kwamandla kwisilawuli semoto) kwiimeko zempazamo ezilinganisiweyo
Kucetyiswa ukuba uqhagamshelane neziko lobuchwephesha lokulungisa ukuze kuvavanywe iisekethe ezine-voltage ephezulu ukuze kuthintelwe iingozi zokhuseleko ezinokubakho ngenxa yokuziqhaqha.
