Njengoba umhlaba usheshisa ukushintshela kwezokuthutha ezisimeme, izimoto zikagesi (EVs) ziyaqhubeka nokuthandwa.Njengoba isidingo sikhuphuka, abakhiqizi bagxile ekuthuthukiseni zonke izici zezimoto zikagesi, kuhlanganise nezinhlelo zabo zokufudumeza.Ukuthuthuka okubili okubalulekile kule ndawo ukwethulwa kwezifudumezi ezipholisayo ezine-positive temperature (PTC) kanye nezifudumezi ezipholile ezine-voltage ephezulu (HV).Lezi zindlela ezintsha azithuthukisi nje kuphela ukunethezeka kwabagibeli kodwa futhi zisiza ukuthuthukisa ukusebenza kahle okuphelele kwezimoto zikagesi.
I-PTC Coolant heater: Ukushintsha Kwegeyimu Yezimoto zikagesi
Inselele enkulu ezimotweni zikagesi, ikakhulukazi ezindaweni ezibandayo, ukushisisa kahle ikhabethe ngaphandle kokukhipha ibhethri.Izifudumezi ze-PTC zinikeza isisombululo esisebenzayo kule nkinga.Lezi zifudumeza zisebenza ngesimiso se-coefficient yokushisa enhle, okusho ukuthi ukumelana kwabo kuyanda njengoba izinga lokushisa likhuphuka.
Izifudumezi ze-PTC zisebenzisa izinto ezithuthukisiwe njengetshe le-ceramic ukusizakala ngalesi sici sokumelana ukuze kuzuzwe ukushisa okushesha nokusebenza kahle.Zihlanganiswe ohlelweni lokushisa lwe-cabin yezimoto zikagesi futhi zingashisa ngokushesha ngaphandle kokusebenzisa amandla amaningi.Ngaphezu kwalokho, izifudumezi ze-PTC zingasiza ukunweba ibanga lokushayela ngokunciphisa ukusetshenziswa kwamandla okuhambisana nokugcina izinga lokushisa elinethezekile ngaphakathi kwemoto.
I-High-Voltage Coolant Heater: Ukwenyuka Kwempumelelo Nokwethenjelwa
Ngaphezu kokushisisa ikhabethe, ukulawulwa kwezinga lokushisa kwe-powertrain yemoto kagesi kanye nephakethe lebhethri kubalulekile ukuze kuzuzwe ukusebenza kahle.Izifudumezi ezipholile ezine-voltage ephezulu eziklanyelwe ngqo izimoto zikagesi zisiza ukufeza lokhu ngokuphatha kahle izimo ezishisayo zezingxenye zemoto.
Izifudumezi ezipholile ezinamandla amakhulu zisebenza ngokuzungeza isipholile esishisayo kuyo yonke i-powertrain nesistimu yebhethri.Lokhu kugcina iphekhi yebhethri ngaphakathi kwebanga lokushisa elilungile lokusebenza, okuqinisekisa ukusebenza kahle okukhulayo nokuphila isikhathi eside.Ukusebenzisa lezi zifudumezi kunciphisa ukulahlekelwa amandla ngesikhathi sezulu esibandayo, kusiza izimoto zikagesi zigcine ibanga ngisho nasezimeni eziyinselele.
Ukupholisa Imoto Kagesi: Iqhawe Elingasuliwe
Nakuba izifudumezi ze-PTC nezifudumezi ezipholisa amandla kagesi aphezulu zidlala indima ebalulekile ezinhlelweni zokushisisa imoto kagesi, ikhwalithi yesipholisi ngokwaso ibaluleke ngokulinganayo.Izipholisa zezimoto zikagesi zenzelwe ngqo ukuhlangabezana nezidingo ezidingekayo zamasistimu okushisa imoto kagesi.Zenzelwe ukuhlinzeka nge-conductivity enhle kakhulu yokushisa, ukumelana nokugqwala kanye ne-conductivity kagesi ephansi.
Ngokusebenzisa isipholile sekhwalithi ephezulu, izimoto zikagesi zingadlulisa kahle ukushisa ukusuka ku-powertrain kuya ku-Isistimu ye-HVAC, okuvumela ukulawula izinga lokushisa kwangaphakathi okungcono.Ukwengeza, lezi zipholile zisiza ukuvimbela ukugqwala ngaphakathi kwesistimu yokushisisa, iqinisekisa ukwethembeka nokusebenza kwayo kwesikhathi eside.
Ekuphetheni:
Intuthuko ezinhlelweni zokushisisa izimoto zikagesi, ikakhulukazi inhlanganisela yezifudumezi ze-PTC, izifudumezi ezipholisa amandla kagesi aphezulu kanye nezipholile zekhwalithi ephezulu, yenza izinguquko embonini yezimoto zikagesi.Lezi zindlela ezintsha zibhekana nezinselele ezihambisana nesimo sezulu esibandayo, ziqinisekisa ukunethezeka kwabagibeli futhi zithuthukise ukusebenza kahle kwamandla.
Ngokuhlanganisa izifudumezi ze-PTC, izimoto zikagesi zingashisisa kahle ikhabethe kuyilapho zinciphisa ukusetshenziswa kwamandla, ngaleyo ndlela zandise ibanga lokushayela.Isifudumezi esipholile esinamandla kagesi aphezulu sithuthukisa ukusebenza kahle kukonke ngokuphatha izimo ezishisayo ze-powertrain nephakethe lebhethri.
Ukwengeza, ukusetshenziswa kwezipholile ezikhethekile ezinhlelweni zokushisisa izimoto zikagesi kukhuthaza ukudluliswa kokushisa okuphumelelayo futhi kuvimbele ukugqwala, kuqinisekisa ukwethembeka kwesikhathi eside nokusebenza kahle.
Njengoba ubuchwepheshe bezimoto zikagesi buqhubeka nokuvela, lezi zinhlelo zokufudumeza ezintsha zingadlala indima ebalulekile ekwandiseni ukutholwa kwabathengi kanye nokubumba ikusasa lezokuthutha ezisimeme.
