Ngophuhliso oluqhubekayo lwangoku lwezithuthi zombane, ngakumbi nangakumbi abachwephesha kunye nabasebenzisi bahlawula ingqalelo ngakumbi nangakumbi kukhuseleko lwe-voltage ephezulu yezithuthi zombane, ngakumbi ngoku ukuba ii-voltage eziphezulu zeqonga (800V nangaphezulu) zisetyenziswa ngokuqhubekayo. Njengomnye wamanyathelo okuqinisekisa ukhuseleko lwamandla ombane aphezulu kwizithuthi zombane, umsebenzi we-high voltage interlock (HVIL) uye wagxininiswa ngakumbi, kwaye uzinzo kunye nesantya sokuphendula somsebenzi we-HVIL ziphuculwa ngokuqhubekayo.
High Voltage Interlock(i-HVIL emfutshane), yindlela yoyilo lokhuseleko lokulawula iisekethe zombane ophezulu kunye neempawu zombane ophantsi. Kwi-design ye-high-voltage system, ukuphepha i-arc ebangelwa yi-high-voltage connector ekusebenzeni kwangempela kwenkqubo yokuqhawula umbane, kunye nokuvala, i-high-voltage connector kufuneka ngokubanzi ibe "i-high-voltage interlock" umsebenzi.
Inkqubo yokudibanisa i-high-voltage ene-high-voltage interlocking function, amandla, kunye nee-terlocking terminals kufuneka ihlangabezane nezi meko zilandelayo xa udibanisa kunye nokuqhawula:
Xa inkqubo yokudibanisa i-high-voltage ixhunyiwe, ii-terminals zamandla zixhunyiwe kuqala kwaye ii-terminals ezidibeneyo zixhunyiwe kamva; xa inkqubo yokudibanisa i-high-voltage inqanyuliwe, ii-terminals ezidibeneyo zivaliwe kuqala kwaye ii-terminals zamandla zivaliwe kamva. Koko kukuthi:iitheminali zamandla ombane aphezulu zinde kuneetheminali zokuvala umbane ophantsi, oqinisekisa ukusebenza kokubhaqwa kophawu oluphakathi kombane ophakathi.
I-high-voltage interlocks isetyenziswa ngokuqhelekileyo kwiisekethe zombane eziphezulu, ezifana nezixhumi eziphezulu ze-voltage, i-MSDs, iibhokisi zokuhambisa i-voltage ephezulu, kunye nezinye iisekethe. Iziqhagamshelo ezine-high-voltage interlocks zinokuqhawulwa ngexesha le-logic ye-high-voltage interlock xa ukuvulwa kwenziwa phantsi kwamandla, kwaye ixesha lokuqhawula lihambelana nobukhulu bomahluko phakathi kobude boqhagamshelwano obusebenzayo be-high-voltage interlock. iitheminali kunye neetheminali zamandla kunye nesantya sokuqhawula. Ngokuqhelekileyo, ixesha lokuphendula lenkqubo kwisekethe ye-terlocking edibeneyo iphakathi kwe-10 ~ kunye ne-100ms xa ukwahlukana kwenkqubo yokudibanisa (ukukhupha) ixesha lingaphantsi kwexesha lokuphendula kwenkqubo, kuya kubakho umngcipheko wokhuseleko wokufakelwa kombane kunye nokukhupha, kwaye Ukuvula okwesibini kuyilelwe ukusombulula ingxaki yeli xesha lokuqhawula, ngokuqhelekileyo, ukuvula okwesibini kunokulawula ngokufanelekileyo eli xesha lokuqhawula ngaphezu kwe-1s, ukuqinisekisa ukhuseleko lwe- ukusebenza.
Ukukhutshwa, ulwamkelo, kunye nokuzimisela komqondiso woqhagamshelo zonke ziqondwa ngomphathi webhetri (okanye iVCU). Ukuba kukho impazamo ye-high-voltage interlock, isithuthi asivumelekanga ukuba sihambe kumandla aphezulu-voltage, kunye neesekethe ezidibeneyo zeemodeli ezahlukeneyo zeemoto zineeyantlukwano ezithile (kubandakanywa ukungafani kwezikhonkwane ezidibeneyo kunye neendawo eziphezulu ze-voltage ezifakwe kwi-interlock. ).
Lo mzobo ungentla ubonisa i-interlock edibeneyo, usebenzisa i-hardwire ukudibanisa izibonakaliso zengxelo ukusuka kwisidibanisi secandelo ngalinye le-voltage ephezulu kuthotho ukwenza i-interlock yesekethe, xa icandelo le-high-voltage kwisekethe lisilela ukudibanisa, isixhobo sokujonga i-interlock siya kuthi kwangoko. ingxelo kwi-VCU, eya kuthi isebenzise isicwangciso esihambelanayo sokunciphisa amandla. Nangona kunjalo, kufuneka kuqatshelwe ukuba asikwazi ukuvumela imoto enesantya esiphezulu ukuba ilahlekelwe ngamandla ngokukhawuleza, ngoko ke isantya semoto kufuneka sithathelwe ingqalelo ekuphunyezweni kweqhinga lokuhla kwamandla, ngoko ke i-interlocks enentambo enzima kufuneka ithathelwe ingqalelo. ihlawulwe xa isicwangciso siqulunqwa.
Ngokomzekelo, i-BMS, i-RESS (inkqubo yebhetri), kunye ne-OBC zihlelwa njengenqanaba le-1, i-MCU kunye ne-MOTOR (imoto yombane) njengenqanaba le-2, kunye ne-EACP (i-compressor air conditioning yombane), i-PTC, kunye ne-DC / DC njengenqanaba le-3.
Izicwangciso ezahlukeneyo ze-HVIL zamkelwa kumanqanaba ahlukeneyo okudibana.
Ekubeni i-high-voltage components isasazwa kuyo yonke isithuthi, oku kukhokelela kubude obude be-interlock hardwire, okukhokelela kwi-wiring enzima kunye nokunyuka kweendleko ze-low-voltage wiring harnesses. Nangona kunjalo, indlela yokudibanisa i-hardwire iyaguquguquka kuyilo, ilula kwingqiqo, inomdla kakhulu, kwaye ikhuthaza uphuhliso.
