Njengoba isabelo semakethe sezimoto zikagesi siqhubeka nokukhula, abenzi bezimoto bashintsha kancane kancane ukugxila kwabo kwe-R&D kumabhethri kagesi kanye nokulawula okuhlakaniphile. Ngenxa yezici zamakhemikhali zebhethri likagesi, izinga lokushisa lizoba nomthelela omkhulu ekusebenzeni kokushaja nokukhipha ishaja kanye nokuphepha kwebhethri likagesi. Ngakho-ke, ekuthuthukisweni kwezimoto zikagesi, ukwakheka kohlelo lokuphatha ukushisa kwebhethri kubaluleke kakhulu. Ngokusekelwe esakhiweni sesistimu yokuphatha ukushisa kwebhethri likagesi esikhona, kuhlanganiswe nobuchwepheshe besistimu yepompo yokushisa ye-Tesla yezindlela eziyisishiyagalombili, isimiso sokusebenza sebhethri likagesi kanye nezinzuzo kanye nokungalungi kohlelo lokuphatha ukushisa kuyahlaziywa. Kunezinkinga ezifana nokulahlekelwa amandla emoto ebandayo, ibanga elifushane lokuhamba, kanye namandla okushaja ancishisiwe, futhi kuphakanyiswa uhlelo lokwenza ngcono uhlelo lokuphatha ukushisa lwebhethri likagesi.
Ngenxa yokungazinzi kwemithombo yamandla yendabuko kanye nokwanda kokungcola kwemvelo, ohulumeni nabakhiqizi bezimoto emazweni ahlukahlukene basheshise ukuguqulwa kwezimoto ezintsha zamandla, bagxile ekukhuthazeni ukuthuthukiswa kwezimoto zikagesi eziqhutshwa kakhulu ugesi omsulwa. Njengoba isabelo semakethe sezimoto zikagesi siqhubeka nokukhula, amabhethri kagesi kanye nokulawula okuhlakaniphile kuba yindlela yokuthuthukiswa kwezobuchwepheshe kwezimoto zikagesi. Asikho isisombululo esingcono esitholiwe. Ngokungafani nezimoto zikaphethiloli zendabuko, izimoto zikagesi azikwazi ukusebenzisa ukushisa okulahliwe ukushisa ikhabhini kanye nebhethri. Ngakho-ke, ezimotweni zikagesi, yonke imisebenzi yokushisa idinga ukuqedwa ngokusebenzisa imithombo yokushisa kanye namandla. Ngakho-ke, indlela yokuthuthukisa ukusetshenziswa kwamandla asele emoto iba yinto kagesi. Inkinga enkulu ngezinhlelo zokuphatha ukushisa kwezimoto.
Iuhlelo lokuphatha ukushisa kwezimoto zikagesiilawula izinga lokushisa lezingxenye ezahlukene zemoto ngokulawula ukuhamba kokushisa, ikakhulukazi okuhlanganisa nokulawulwa kwezinga lokushisa kwemoto, ibhethri kanye ne-cockpit. Uhlelo lwebhethri kanye ne-cockpit kudingeka kucatshangelwe ukulungiswa okubili kokubanda nokushisa, kuyilapho uhlelo lwemoto ludinga kuphela ukucabangela ukushabalaliswa kokushisa. Iningi lezinhlelo zokuqala zokuphatha ukushisa zezimoto zikagesi kwakuyizinhlelo zokushabalaliswa kokushisa ezipholile emoyeni. Lolu hlobo lohlelo lokuphatha ukushisa lwathatha ukulungiswa kwezinga lokushisa kwe-cockpit njengomgomo oyinhloko wokuklama uhlelo, futhi kwakungavamile ukubhekwa njengokulawulwa kwezinga lokushisa kwemoto nebhethri, ukuchitha amandla ohlelo olunezinjini ezintathu ngesikhathi sokusebenza. Njengoba amandla emoto nebhethri ekhula, uhlelo lokushabalaliswa kokushisa olupholile emoyeni alusakwazi ukuhlangabezana nezidingo eziyisisekelo zokuphathwa kokushisa kwemoto, futhi uhlelo lokuphatha ukushisa selungene enkathini yokupholisa uketshezi. Uhlelo lokupholisa uketshezi alugcini nje ngokuthuthukisa ukusebenza kahle kokushabalaliswa kokushisa, kodwa futhi lukhulisa uhlelo lokuvikela ibhethri. Ngokulawula umzimba we-valve, uhlelo lokupholisa uketshezi alukwazi ukulawula kuphela indlela yokushisa, kodwa futhi lusebenzise ngokugcwele amandla angaphakathi emotweni.
Ukushisa kwebhethri kanye ne-cockpit kuhlukaniswe kakhulu ngezindlela ezintathu zokushisa: ukushisa kwe-thermistor ye-temperature coefficient (PTC), ukushisa kwefilimu yokushisa kagesi kanye nokushisa kwephampu yokushisa. Ngenxa yezici zamakhemikhali zebhethri yamandla ezimoto zikagesi, kuzoba nezinkinga ezifana nokulahlekelwa amandla emoto ebandayo, ibanga elifushane lokuhamba, kanye namandla okushaja ancishisiwe ngaphansi kwezimo zokushisa eziphansi. Ukuze kuqinisekiswe ukuthi izimoto zikagesi zingafinyelela izimo zokusebenza ezifanele ngaphansi kwezimo ezahlukahlukene ezimbi kakhulu, Ukuze kuhlangatshezwane nezidingo zokusetshenziswa, uhlelo lokuphatha ukushisa kwebhethri ludinga ukuthuthukiswa futhi lulungiselelwe izimo zokushisa eziphansi.
Indlela yokupholisa ibhethri
Ngokusho kwemidiya ehlukene yokudlulisa ukushisa, uhlelo lokuphatha ukushisa kwebhethri lungahlukaniswa ngezinhlobo ezintathu: uhlelo lokuphatha ukushisa komoya ophakathi nendawo, uhlelo lokuphatha ukushisa koketshezi ophakathi nendawo kanye nohlelo lokuphatha ukushisa kwezinto zokushintsha kwesigaba, kanye nohlelo lokuphatha ukushisa komoya ophakathi nendawo lungahlukaniswa ngohlelo lokupholisa lwemvelo kanye nohlelo lokupholisa umoya. Kunezinhlobo ezimbili zohlelo lokupholisa.
Ukushisa kwe-PTC thermistor kudinga ukuhlela iyunithi yokushisa ye-PTC thermistor kanye ne-insulating coating ezungeze iphakethe lebhethri. Uma iphakethe lebhethri lemoto lidinga ukufudunyezwa, uhlelo lunika amandla i-PTC thermistor ukuze ikhiqize ukushisa, bese luvunguza umoya nge-PTC ngefeni (Isifudumezi Sokupholisa se-PTC/Isifudumezi Somoya se-PTC). Amafin okushisa e-thermistor ayayifudumeza, bese ekugcineni eqondisa umoya oshisayo ephaketheni lebhethri ukuze ujikeleze ngaphakathi, ngaleyo ndlela kufudunyezwe ibhethri.
