Imfuno ekhulayo yezithuthi zombane izisa imfuneko yeenkqubo zokufudumeza ezisebenzayo ukugcina iibhetri kunye nezinye izinto zikwiqondo lobushushu elifanelekileyo. Izifudumezi ze-PTC (Positive Temperature Coefficient) eziphezulu zidlala indima ebalulekileyo kule ndawo, zibonelela ngezisombululo zokufudumeza ezithembekileyo nezisebenzayo kwizithuthi zombane.
Enye yezona zicelo ziphambili zei-heater ye-PTC ene-voltage ephezulus ikwizifudumezi zebhetri zebhasi zombane. Ezi zifudumezi zenzelwe ukugcina ubushushu bebhetri bukwinqanaba elifanelekileyo, ukuqinisekisa ukusebenza kakuhle kunye nobude bexesha. Njengoko iibhasi zombane zithandwa ngakumbi kwiinkqubo zothutho zasezidolophini, imfuneko yezisombululo zokufudumeza iibhetri ezinokuthenjwa ibaluleke ngakumbi kunangaphambili.
Ukongeza kwii-heater zebhetri, ii-heater ze-PTC ezine-voltage ephezulu zikwasetyenziswa kwii-heaters ze-coolant ezinoxinzelelo oluphezulu kwizithuthi zombane. Ezi heater zenzelwe ukufudumeza i-coolant kwinkqubo yokupholisa yesithuthi, ukuqinisekisa ukuba umbane usebenza kubushushu obufanelekileyo. Oku kubalulekile ekugcineni ukusebenza kakuhle kwesithuthi sakho, ingakumbi kwiimeko zemozulu ebandayo.
Enye yezona nzuzo ziphambili zee-heaters ze-PTC ezine-voltage ephezulu kukukwazi kwazo ukuzilawula. Izinto ze-PTC zine-coefficient yobushushu eyakhayo, oko kuthetha ukuba ukumelana kwazo kuyanda njengoko ubushushu busanda. Olu phawu lokuzilawula luvumela i-heater ukuba igcine ubushushu obungaguqukiyo ngaphandle kwesidingo senkqubo yolawulo lwangaphandle, nto leyo eyenza ukuba ithembeke kwaye isebenzise amandla kakuhle.
Ukongeza,Isifudumezi se-PTC esipholileyo se-HVEzi zixhobo ziyaziwa ngokukwazi kwazo ukufudumeza ngokukhawuleza. Oku kubalulekile kwizithuthi zombane njengoko kuqinisekisa ukuba inkqubo yokufudumeza inokuzisa ngokukhawuleza izinto kubushushu obufunekayo nokuba zikwimeko yemozulu embi kakhulu. Impendulo yokufudumeza ngokukhawuleza ye-PTC heater ikwanceda ukonga amandla kuba inciphisa ixesha ekufuneka i-heater isebenze ngalo.
Enye inzuzo yezifudumezi ze-PTC ezine-voltage ephezulu bubukhulu bazo obuncinci kunye nobunzima obulula. Oku kuzenza zilungele izithuthi zombane, apho indawo kunye nobunzima zizinto ezibalulekileyo. Uyilo oluncinci lwesifudumezi se-PTC luvumela ukuhlanganiswa okulula kwinkqubo yokufudumeza yesithuthi ngaphandle kokuthatha indawo exabisekileyo okanye ukongeza ubunzima obungeyomfuneko.
Njengoko imfuno yezithuthi zombane iqhubeka ikhula, imfuneko yeenkqubo zokufudumeza ezisebenzayo nezithembekileyo iya isanda. Izifudumezi ze-PTC ezine-voltage ephezulu ziyahlangabezana nale mfuno kwaye zibonelela ngeenzuzo ezahlukeneyo ezenza zibe sisisombululo esifanelekileyo sokufudumeza kwizithuthi zombane.
Isishwankathelo,Isifudumezi se-EV esipholileyoIi-s ziguqula ukufudumeza iimoto ngombane, zibonelela ngezisombululo zokufudumeza ezinokuthenjwa, ezisebenzayo nezincinci kwiintlobo ngeentlobo zezicelo. Nokuba kukufudumeza iibhetri kwiibhasi zombane okanye ukufudumeza okupholileyo kwiinkqubo zoxinzelelo oluphezulu, ii-PTC heaters zibonakala zitshintsha umdlalo kwishishini lokufudumeza iimoto ngombane. Ngeempawu zazo ezizilawulayo, amandla okufudumeza ngokukhawuleza kunye noyilo oluncinci, ii-PTC heaters ezine-voltage ephezulu ziya kudlala indima ebalulekileyo ekukhuleni okuqhubekayo kunye nokwamkelwa kwezithuthi zombane kwihlabathi liphela.
