Entuthukweni enkulu embonini yezimoto zikagesi (EV), kuthuthukiswe i-heater entsha ye-PTC (positive temperature coefficient) enamandla aphezulu ethembisa ukuthuthukisa kakhulu ukusebenza kahle kanye nokusebenza kwezinhlelo zokushisa ze-EV coolant. Eyaziwa ngokuthi i-HV PTC heater, lobu buchwepheshe obuphambili buzoshintsha indlela izimoto zikagesi ezifudumeza ngayo i-coolant, okuzoletha izinzuzo eziningi kubakhiqizi be-EV kanye nabathengi.
Izimoto zikagesi zendabuko zithembele kuma-heater e-PTC endabuko ukuze zifudumale i-coolant ohlelweni. Lawa ma-heater asebenzisa ama-resistor ukukhiqiza ukushisa lapho ugesi udlula kuwo, kodwa afudumala kancane futhi avame ukungasebenzi kahle. Lokhu kuholela ezikhathini ezinde zokushisa kanye nokusetshenziswa kwamandla okwandisiwe, okuthinta kabi ububanzi kanye nokusebenza kwemoto kagesi.
Kodwa-ke, i-heater entsha ye-PTC enomfutho ophezulu inezinzuzo eziningana ezibalulekile kune-heater ye-PTC yendabuko. Okokuqala, isebenza nge-voltage ephezulu, eshisa ngokushesha futhi ithuthukise ukusebenza kahle kwamandla. Lokhu kusho ukuthi izimoto zikagesi ezihlonyiswe nge-heater ye-HV PTC zingafudumeza i-coolant yazo ngokushesha futhi zibe nomthelela omncane ebangeni lazo lokushayela, ekugcineni zithuthukise ulwazi lokushayela oluphelele lwabathengi.
Ngaphezu kwalokho, ubuchwepheshe obuthuthukisiwe obusetshenziswa kuIsifudumezi se-HV PTCs ivumela ukulawulwa okunembile kokushisa, iqinisekisa ukuthi i-coolant ifudunyezwa kuze kufike ezingeni lokushisa elifanele ukuze imoto isebenze kahle futhi ikhululeke kumuntu ohambayo. Lokhu akugcini nje ngokuthuthukisa ukusebenza kahle kwezinhlelo zokushisa ze-EV, kodwa futhi kuthuthukisa ulwazi lomsebenzisi jikelele, okwenza ama-EV abe inketho ekhangayo kakhulu kubathengi.
Ukwethulwa kwama-heater e-HV PTC kubaluleke kakhulu kubakhiqizi bezimoto zikagesi njengoba kunikeza ithuba lokukhulisa ukusebenza kwezimoto nokukhanga. Ngokuhlinzeka ngokushisa okupholile okusheshayo nokusebenzayo, abakhiqizi be-EV bangathuthukisa ukuncintisana kwemikhiqizo yabo emakethe ye-EV eqhubeka nokuxinana, okungase kudonsele amakhasimende amaningi futhi kuthole indawo eqinile embonini.
Abakhiqizi bezimoto zikagesi abaningana abaphambili sebeqalile ukuhlanganisai-heater ye-PTC enamandla aphezulubangena ezimotweni zabo, beqaphela izinzuzo ezingaba khona lobu buchwepheshe obungaziletha. Kule nqubo, abagcini nje ngokuthuthukisa ukusebenza kahle kwezimoto zikagesi kodwa futhi babonisa ukuzibophezela kwabo emisha kanye nentuthuko kwezobuchwepheshe bezimoto zikagesi.
Njengoba imakethe yezimoto zikagesi iqhubeka nokukhula nokuthuthuka, ukuthuthukiswa kobuchwepheshe obuthuthukisiwe njengezifudumezi ze-PTC ezinamandla aphezulu kuzodlala indima ebalulekile ekwakheni ikusasa lezimoto zikagesi. Ngokuvumela ukufudumeza okupholile okusheshayo nokusebenzayo, lobu buchwepheshe bunamandla okubhekana nezinye zezinselelo ezibalulekile ezibhekene nokwamukelwa kabanzi kwezimoto zikagesi, njengokukhathazeka kobubanzi kanye nezinkinga zokusetshenziswa kwamandla.
Ngaphezu kwalokho, ukwethulwa kwama-heater e-PTC ane-voltage ephezulu kuphawula isinyathelo esibalulekile ekuthuthukisweni okuqhubekayo kanye nokuthuthukiswa kobuchwepheshe bezimoto zikagesi. Njengoba abakhiqizi belwela ukwenza izimoto zikagesi zincintisane futhi zikhange kubathengi, ukusungula izinto ezintsha ezinhlelweni zokushisa nokupholisa cishe kuzodlala indima ebaluleke kakhulu ekufezeni le migomo.
Ekugcineni, ukuthuthukiswa nokusetshenziswa kweIsifudumezi sokupholisa se-EVKuphawula ingqophamlando ebalulekile ekuthuthukisweni okuqhubekayo kwezimoto zikagesi. Ngokuletha ukusebenza okuthuthukisiwe, ukusebenza kahle kanye nokuhlangenwe nakho komsebenzisi, ubuchwepheshe bunamandla okuqhuba ukwamukelwa kabanzi kwezimoto zikagesi futhi busheshise ukushintshela ohlelweni lokuthuthwa oluhlala isikhathi eside noluluhlaza.
