Njengoko ihlabathi litshintshela kwikamva elizinzileyo, izithuthi zombane (ii-EV) ziya zithandwa kakhulu ngenxa yeengenelo zazo zokusingqongileyo kunye nokusebenza kakuhle kwamandla. Nangona kunjalo, enye yeengxaki ezijongene nezithuthi zombane kukufuna ukugcina ukusebenza kakuhle kwebhetri, ingakumbi kwiimeko zemozulu ebandayo. Kulapho izifudumezi zebhetri ezipholileyo kunye nezifudumezi zePTC ezine-voltage ephezulu zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kwezithuthi zombane.
Izifudumezi zokupholisa iibhetri, ezaziwa ngokubaisifudumezi se-PTC esine-voltage ephezulu (i-positive temperature coefficient)s, ziyinxalenye ebalulekileyo yezithuthi zombane, ingakumbi kwiindawo ezinemozulu ebandayo. Ezi heater zenzelwe ukulawula ubushushu bepakethi yebhetri kunye negumbi, ukuqinisekisa ukuba ibhetri isebenza ngaphakathi komgangatho wobushushu ofanelekileyo ukuze kuphuculwe ukusebenza kunye nobude bexesha.
Kwimozulu ebandayo, ukusebenza kakuhle kwebhetri kunokuncipha kakhulu ukuba ubushushu obufanelekileyo abugcinwa. Ubushushu obuphantsi bubangela ukuba ukumelana kwangaphakathi kwebhetri kunyuke, okuchaphazela amandla ayo okuhambisa amandla. Kulapho ke ii-heaters ze-coolant zebhetri zingena khona, njengoko zigcina ubushushu bebhetri ngaphakathi koluhlu olufanelekileyo, ziqinisekisa ukuba ibhetri inika amandla kunye noluhlu olufunekayo nokuba iimeko zangaphandle zinjani na.
Ii-heater ze-PTC ezine-voltage ephezulu zisebenza kakhulu kule nto kuba zisebenzisa i-PTC effect ukulungisa ngokuzenzekelayo amandla aphumayo ngokusekelwe kubushushu bebhetri. Njengoko ubushushu busiya buhla, ukumelana kwezinto ze-PTC kuyanda, okubangela ukuba amandla aphumayo aphezulu ukuze kufudumale ibhetri. Ngokwahlukileyo koko, njengoko ubushushu busanda, ukumelana kuyancipha, ngaloo ndlela kunciphisa amandla aphumayo ukuze kuthintelwe ubushushu obugqithisileyo. Olu phawu oluzilawulayo lwenzaIsifudumezi se-EV PTCSisisombululo esisebenzayo nesithembekileyo sokugcina amaqondo obushushu ebhetri afanelekileyo kwiimoto zombane.
Ukongeza, ezi heater zidlala indima ebalulekileyo ekuqinisekiseni intuthuzelo yabakhweli ngokubonelela ngokufudumeza kakuhle iikhabhini kwizithuthi zombane. Iiheater ze-PTC ezine-voltage ephezulu zisebenzisa ubushushu obungafunwayo obuveliswa ziibhetri kunye ne-elektroniki ukuze zifudumeze kakuhle ikhabhini ngaphandle kokuxhomekeka kwinkqubo yokufudumeza ephambili yesithuthi, ngaloo ndlela zinciphisa ukusetyenziswa kwamandla kwaye zandise umgama wokuqhuba kwesithuthi.
Ukongeza kulawulo lobushushu,isifudumezi sebhetri esipholileyoIi-heater ze-PTC kunye nee-high-voltage ze-PTC zinegalelo kukhuseleko olupheleleyo lwezithuthi zombane. Ngokugcina iibhetri kumaqondo obushushu afanelekileyo, ezi heater zinceda ekuthinteleni ukubaleka kobushushu kunye nezinye iingozi zokhuseleko ezinxulumene neemeko zobushushu obugqithisileyo. Oku kubaluleke kakhulu kwizithuthi zombane kuba ibhetri yinxalenye ebalulekileyo yombane wesithuthi.
Ukongeza, ukusetyenziswa kwezifudumezi ze-PTC ezine-voltage ephezulu kwizithuthi zombane kuhambelana nokugxila kweshishini ekusebenziseni amandla kakuhle nasekuzinzeni. Ezi zifudumezi zenzelwe ukusebenza kakuhle, ukunciphisa inkunkuma yamandla kunye nokunciphisa impembelelo iyonke kwizithuthi zombane kwindalo esingqongileyo. Ngokuphucula ukusetyenziswa kobushushu obumdaka kunye nokulawula amaqondo obushushu ebhetri kunye neekhabhathi, izifudumezi ze-PTC ezine-voltage ephezulu zinceda ukuphucula ukusebenza kakuhle kwamandla kwezithuthi zombane, nto leyo ezenza zibe luncedo olukhulu kwizisombululo zothutho oluzinzileyo.
Njengoko imfuno yezithuthi zombane iqhubeka ikhula, ukubaluleka kwezifudumezi zebhetri kunye nezifudumezi zePTC ezine-voltage ephezulu ekuqinisekiseni ukusebenza kakuhle kunye nokhuseleko lwezithuthi zombane akunakugxininiswa kakhulu. Ezi zinto zidlala indima ebalulekileyo ekusombululeni imingeni enxulumene nokusebenza kwemozulu ebandayo ngelixa zikwanceda ukuphucula ukusebenza kakuhle kunye nokuzinza kwezithuthi zombane.
Ngamafutshane, ii-heaters ze-battery coolant kunye nee-heaters ze-PTC ezine-voltage ephezulu zizinto ezibalulekileyo kwizithuthi zombane, ezisetyenziselwa ukulawula ubushushu bepakethi yebhetri kunye nekhabhathi, ukuqinisekisa intuthuzelo yabakhweli, kunye nokuphucula ukhuseleko kunye nokusebenza kakuhle kwezithuthi zombane. Njengoko ishishini leemoto liqhubeka nokwamkela umbane, uphuhliso kunye nokuhlanganiswa kwezisombululo zokufudumeza eziphambili kubalulekile ekuqhubeleni phambili ukwamkelwa ngokubanzi kwezithuthi zombane kunye nokubumba ikamva lothutho oluzinzileyo.
