Inkcazo

Njengoko izithuthi zombane (ii-EV) ziqhubeka nokutsalwa kwishishini leemoto, kuphuhliswa ubuchwepheshe obutsha ukuze busebenze kakuhle kwaye buthembeke ngakumbi. Enye yezo teknoloji yi-high-voltage PTC (positive temperature coefficient) heater, esetyenziswa njenge-electric coolant heater kwizithuthi zombane. Kule blog, siza kuxoxa ngeenzuzo zokusebenzisa ii-high-voltage PTC heaters kwizithuthi zombane.

Okokuqala,Isifudumezi se-EV PTClicandelo eliphambili kwinkqubo yolawulo lobushushu bezithuthi zombane. Inceda ukugcina amaqondo obushushu afanelekileyo ebhetri yesithuthi sakho kunye noqeqesho lokuqhuba, ukuqinisekisa ukusebenza kakuhle kunye nokwandisa ubomi bezi zinto zibalulekileyo. Ngokungafaniyo nezithuthi zemveli zenjini yokutsha yangaphakathi, izithuthi zombane azivelisi ubushushu obungafunekiyo, ngoko ke kufuneka enye indlela yokufudumeza ingaphakathi lesithuthi kunye nokugcina ubushushu bebhetri kwiindawo ezibandayo. Izifudumezi ze-PTC ezinoxinzelelo oluphezulu zisisombululo esisebenzayo kulo mceli mngeni kuba zinokuvelisa ubushushu ngokukhawuleza ngaphandle kwesidingo seenkqubo ezintsonkothileyo nezinkulu zokupholisa.

Ukongeza, ii-heater ze-PTC ezine-voltage ephezulu zaziwa ngokukwazi kwazo ukufudumeza ngokukhawuleza, nto leyo eyenza ukuba zibe zilungele iimoto zombane. Ezi heater zisebenzisa izixhobo ze-ceramic eziqhubayo ezilungisa ngokuzenzekelayo amandla eziwasebenzisayo, zivumela ukufudumeza ngokukhawuleza nangokulinganayo. Oku kubaluleke kakhulu kwiimoto zombane, apho ukusebenza kakuhle kwamandla kuyinto ephambili. Ngokusebenzisa ii-heater ze-PTC ezine-voltage ephezulu, abavelisi bezithuthi zombane banokuqinisekisa ukuba ingaphakathi lesithuthi lifudunyezwa ngokukhawuleza nangokufanelekileyo ngaphandle kokukhupha ibhetri ngokungafanelekanga.

Ukongeza kwizakhono zazo zokufudumeza ngokukhawuleza, ii-heater ze-PTC ezine-voltage ephezulu zaziwa ngokuthembeka kwazo nokhuseleko lwazo. Ngokungafaniyo nezinto zokufudumeza zemveli, ii-heater ze-PTC azixhomekeki kwi-sensor yobushushu eyahlukileyo ukulawula imveliso yazo. Endaweni yoko, zizilawula ngokwazo ukusetyenziswa kwamandla ngokusekelwe kubushushu bendawo ezikuyo. Olu phawu lokuzilawula luzenza zingabi sengozini yokutshisa kakhulu, nto leyo ebalulekileyo ekuqwalaselweni kokhuseleko kwizithuthi zombane. Ukongeza, ii-heater ze-PTC zenzelwe ukumelana noxinzelelo lobushushu kunye noxinzelelo loomatshini, nto leyo eyonyusa ukuthembeka kwazo kwizicelo zezithuthi ezifuna amandla.

Enye inzuzo ebalulekileyo yokusebenzisa izifudumezi ze-PTC ezine-voltage ephezulu kwizithuthi zombane kukuyilwa kwazo okulula nokuncinci. Abavelisi bezithuthi zombane bahlala besebenza ukunciphisa ubunzima kunye nobukhulu bezithuthi zabo ukuze bandise ububanzi kunye nokusebenza. Ngokusebenzisai-heater ye-PTC ene-voltage ephezuluabavelisi banokuphelisa isidingo seenkqubo zokupholisa ezinkulu, bakhulule indawo exabisekileyo kwizithuthi kwaye banciphise ubunzima bayo yonke into. Oku akupheleli nje ekunyuseni ukusebenza kakuhle kwesithuthi, kodwa kukwavumela ukhetho loyilo olunobuchule noluguquguqukayo.

Okokugqibela, ii-heater ze-PTC ezine-voltage ephezulu zibonelela ngesisombululo sokufudumeza esizinzileyo nesinobuhlobo nokusingqongileyo kwizithuthi zombane. Ngokungafaniyo nee-heater zemveli ezixhomekeke kumafutha e-fossil okanye iinkqubo ezintsonkothileyo zokupholisa, ii-heater ze-PTC zisebenzisa umbane ukuvelisa ubushushu, zizenze zibe lukhetho lokufudumeza olucocekileyo nolusebenzayo. Oku kuhambelana nenjongo iyonke yezithuthi zombane yokunciphisa ukukhutshwa kwekhabhoni kunye nokuxhomekeka kwimithombo yamandla engahlaziyekiyo. Ukongeza, indlela ezilawula ngayo ii-heater ze-PTC iqinisekisa ukuba zisebenzisa kuphela umbane ofunekayo, ngaloo ndlela zinciphisa inkunkuma yamandla.

Ngamafutshane, ukusebenzisaIsifudumezi sombane se-PTC esine-voltage ephezuluIimoto zombane zibonelela ngeenzuzo ezininzi, kubandakanya amandla okufudumeza ngokukhawuleza, ukuthembeka, ukhuseleko, uyilo olukhaphukhaphu, kunye nokuzinza kokusingqongileyo. Njengoko imfuno yezithuthi zombane iqhubeka ikhula, abavelisi kufuneka basebenzise izisombululo zolawulo lobushushu oluphambili, ezifana nezifudumezi ze-PTC ezine-voltage ephezulu, ukuze kwandiswe ukusebenza kakuhle kwezithuthi kunye nokusebenza kwazo. Ngokusebenzisa obu buchwepheshe butsha, izithuthi zombane zinokubonelela ngamava okuqhuba akhululekileyo nathembekileyo ngelixa zinciphisa impembelelo yokusingqongileyo.
