Izithuthi zombane (ii-EV) ziya zithandwa kwihlabathi liphela ngenxa yokuba zinobuhlobo nokusingqongileyo kunye nokonga ipetroli. Nangona kunjalo, umceli mngeni oqhelekileyo kwizithuthi zombane kukugcina ubushushu obufanelekileyo kwikhabhini ngexesha lobusika obuqatha. Ukulwa noku, abavelisi bazise izisombululo ezintsha ezifana nezifudumezi zomoya ze-electric vehicle PTC (Positive Temperature Coefficient) kunye nezifudumezi ezipholileyo. Kule bhlog, siza kujonga nzulu kwezi nkqubo zokufudumeza eziphambili, sixoxe ngezibonelelo zazo kunye nendlela ezinokunceda ngayo ukuphucula amava azo e-EV ngokubanzi.
Okokuqala, qonda i-heater ye-PTC:
Ii-heater ze-PTC zahlukile kubuchule bazo bokusebenzisa iipropati ze-coefficient zobushushu ezilungileyo zezinto ezithile ukulawula ubushushu obuphumayo. Ngokungafaniyo neendlela zendabuko zokufudumeza, ii-heater ze-PTC azifuni zinzwa zangaphandle okanye iinkqubo zolawulo ezintsonkothileyo. Endaweni yoko, ziyazilungisa ngokwazo ukuze zihambelane nokusingqongileyo, ziqinisekisa ukusasazwa kobushushu okuhlala kusenzeka nangokufanelekileyo.
2. Isifudumezi somoya se-EV PTC:
1. Ukusebenza kakuhle kokufudumeza:
Izifudumezi zomoya ze-EV PTC zidlala indima ebalulekileyo ekugcineni ubushushu obukhululekileyo bekhabhathi kubakhweli. Ezi zifudumezi zibonelela ngokusasazwa kobushushu okukhawulezayo, okulinganayo, okuphucula umgangatho wobushushu ngaphakathi emotweni. Ngetekhnoloji ye-PTC, kuveliswa ubushushu obufunekayo kuphela, okunciphisa ukusetyenziswa kwamandla kunye nokonyusa ukusebenza kakuhle kwamandla.
2. Phucula ukhuseleko:
Ukhuseleko lwee-heaters zomoya ze-EV PTC luyancomeka. Ekubeni zilungisa ubushushu ngokweemeko ezingqongileyo, umngcipheko wobushushu obugqithisileyo okanye ii-short circuits uncitshiswa kakhulu. Ke ngoko, ukusetyenziswa kwee-heaters zomoya ze-PTC kunokuphucula ukhuseleko lwabakhweli kwizithuthi zombane - into ebalulekileyo xa kubanda.
3. Nciphisa ukusetyenziswa kwamandla:
Xa kuthelekiswa nezifudumezi zemveli, izifudumezi zomoya ze-EV PTC zisebenzisa amandla amancinci. Ngenxa yendalo yobuchwepheshe be-PTC eyazithintelayo, ezi zifudumezi zinciphisa ngokuzenzekelayo ubushushu xa kufikwa kubushushu obufunekayo, nto leyo evumela ukusetyenziswa kwamandla afanelekileyo. Olu phawu lokonga amandla lunceda ukwandisa uluhlu lokuqhuba lwezithuthi zombane, ngaloo ndlela luphucula uzinzo lwazo ngokubanzi.
Ntathu.Isifudumezi se-EV PTC esipholileyo:
1. Ukufudumeza injini ngokufanelekileyo:
Isifudumezi sokupholisa se-EV PTC senzelwe ukulawula ubushushu besifudumezi senjini ngaphambi kokuba siqalise imoto. Ukuqalisa ngokubandayo kunokubeka uxinzelelo olongezelelweyo kwisithuthi sombane, nto leyo echaphazela ukusebenza kwebhetri. Ngokufudumeza isifudumezi senjini kwangaphambili, isifudumezi sokupholisa se-PTC siyayisusa le ngxaki, siqinisekise ukusebenza kakuhle kunye nokusebenza kakuhle.
2. Ubomi bebhetri:
Amaqondo obushushu abandayo kakhulu anokuchaphazela kakubi ukusebenza kakuhle kunye nobomi beebhetri zezithuthi zombane. I-heater ye-PTC coolant iyawunciphisa lo mngcipheko ngokufudumeza ipakethe yebhetri ngaphambi kokuba iqalise. Ngokugcina ubushushu bebhetri bulungile, ezi heater zinceda ekwandiseni ubomi bebhetri kwaye ziqinisekise ukusebenza rhoqo, ingakumbi ebusika.
3. Nciphisa ukusetyenziswa kwamandla:
Njengezifudumezi zomoya zePTC zezithuthi zombane, izifudumezi zokupholisa zePTC nazo zigxila ekusebenziseni amandla kakuhle. Ngokusebenzisa itekhnoloji yePTC, ezi zifudumezi zisebenzisa umbane kuphela xa zifudumeza isikhumezi ngamandla. Nje ukuba ubushushu obufunekayo bufikelelwe, isifudumezi sinciphisa ngokuzenzekelayo ukusetyenziswa kwamandla. Oku kuqinisekisa ukuba iimfuno zamandla zizonke zesithuthi ziyaphuculwa ngelixa zisabonelela ngobushushu obufunekayo.
Isine. Ukuqukumbela:
Izithuthi zombane ziyaqhubeka nokukhula ngokukhawuleza, kwayeIzifudumezi ze-PTCzizinto ezibalulekileyo zokongeza amava asebusika kubanini bezithuthi zombane. Ii-heater zomoya ze-EV PTC kunye nee-coolant heater zibonelela ngomthamo wokufudumeza ongenakuthelekiswa nanto ngelixa zibeka phambili ukhuseleko, ukusebenza kakuhle kwamandla kunye nobomi bebhetri. Njengoko ezi zisombululo zintsha zokufudumeza ziya kufakwa ngakumbi kuyilo lwezithuthi zombane, abaqhubi banokuqiniseka ukuba izithuthi zabo zombane ziya kubonelela ngozinzo lokusingqongileyo kwaye zibonelele ngamaqondo obushushu afudumeleyo, akhululekileyo nakwiimini ezibandayo.
