Njengoko ihlabathi likhawulezisa ukutshintshela kuthutho oluzinzileyo, izithuthi zombane (ii-EV) ziyaqhubeka nokuthandwa. Njengoko imfuno isanda, abavelisi bagxile ekuphuculeni yonke into yezithuthi zombane, kuquka neenkqubo zabo zokufudumeza. Inkqubela ephambili kule ndawo kukungeniswa kwe-positive temperature coefficient (PTC) coolant heaters kunye ne-high-voltage (HV) coolant heaters. Ezi zinto zintsha aziphuculi nje kuphela intuthuzelo yabakhweli kodwa zikwanceda ekuphuculeni ukusebenza kakuhle kwezithuthi zombane.
Isifudumezi sePTC esipholileyo: Utshintsho kwiZithuthi zoMbane
Umceli mngeni omkhulu kwizithuthi zombane, ingakumbi kwiindawo ezibandayo, kukufudumeza ikhabhini ngokufanelekileyo ngaphandle kokukhupha ibhetri. Ii-heater ze-PTC zibonelela ngesisombululo esisebenzayo kule ngxaki. Ezi heater zisebenza ngokomgaqo we-positive temperature coefficient, oko kuthetha ukuba ukumelana kwazo kuyanda njengoko ubushushu busanda.
Izifudumezi ze-PTC zisebenzisa izixhobo eziphambili ezifana nelitye le-ceramic ukuze zisebenzise olu phawu lokuxhathisa ukuze zifumane ukufudumeza okukhawulezayo nokusebenzayo. Zifakwe kwinkqubo yokufudumeza yekhabhini yezithuthi zombane kwaye zinokufudumeza ngokukhawuleza ngaphandle kokusebenzisa amandla amaninzi. Ukongeza, izifudumezi ze-PTC zinokunceda ukwandisa umgama wokuqhuba ngokunciphisa ukusetyenziswa kwamandla okuhambelana nokugcina ubushushu obukhululekileyo ngaphakathi kwesithuthi.
Isifudumezi seSipholisi seVolthi ephezulu: Ukwanda Kokusebenza Nokuthembeka
Ukongeza ekufudumaleni kwekhabhathi, ulawulo lobushushu lwe-powertrain yesithuthi sombane kunye nebhetri kubalulekile ekufezekiseni ukusebenza kakuhle. Izifudumezi zokupholisa ezine-voltage ephezulu ezenzelwe ngokukodwa izithuthi zombane zinceda ekufezekiseni oku ngokulawula ngokufanelekileyo iimeko zobushushu zezixhobo zesithuthi.
Izifudumezi ze-coolant ezine-voltage ephezulu zisebenza ngokujikeleza i-coolant eshushu kuyo yonke i-powertrain kunye nenkqubo yebhetri. Oku kugcina ipakethi yebhetri ikwinqanaba elifanelekileyo lobushushu bokusebenza, kuqinisekisa ukusebenza kakuhle kunye nobude bexesha. Ukusebenzisa ezi zifudumezi kunciphisa ukulahleka kwamandla ngexesha lemozulu ebandayo, kunceda izithuthi zombane zigcine umgama ofanelekileyo nokuba zikwimeko ezinzima.
Isipholisi seMoto yoMbane: Iqhawe elingadunyiswanga
Nangona ii-PTC heaters kunye nee-high-voltage coolant heaters zidlala indima ebalulekileyo kwiinkqubo zokufudumeza iimoto zombane, umgangatho we-coolant ngokwawo ubaluleke ngokulinganayo. Ii-coolant zezithuthi zombane zenzelwe ngokukodwa ukuhlangabezana neemfuno ezifunekayo zeenkqubo zokufudumeza iimoto zombane. Zenzelwe ukubonelela nge-thermal conductivity egqwesileyo, ukumelana nokugqwala kunye ne-conductivity ephantsi yombane.
Ngokusebenzisa isibandisi esisemgangathweni ophezulu, izithuthi zombane zinokudlulisela ubushushu ngokufanelekileyo ukusuka kumatshini wamandla ukuyaInkqubo ye-HVAC, okuvumela ulawulo olungcono lobushushu bangaphakathi. Ukongeza, ezi zipholisi zinceda ekuthinteleni ukugqwala kwinkqubo yokufudumeza, ziqinisekisa ukuthembeka kwayo kunye nokusebenza kwayo ixesha elide.
ukuququmbela:
Inkqubela phambili kwiinkqubo zokufudumeza iimoto ngombane, ingakumbi indibaniselwano yezifudumezi ze-PTC, izifudumezi zokupholisa ezine-voltage ephezulu kunye nezifudumezi ezikumgangatho ophezulu, ziguqula ishishini lezithuthi zombane. Ezi zinto zintsha zijongana nemingeni enxulumene nemozulu ebandayo, ziqinisekisa intuthuzelo yabakhweli kwaye ziphucula ukusebenza kakuhle kwamandla.
Ngokudibanisa izifudumezi ze-PTC, izithuthi zombane zinokufudumeza ikhabhini ngempumelelo ngelixa zinciphisa ukusetyenziswa kwamandla, ngaloo ndlela zandisa umgama wokuqhuba. Isifudumezi sokupholisa esine-voltage ephezulu siphucula ngakumbi ukusebenza kakuhle ngokulawula iimeko zobushushu ze-powertrain kunye nebhetri.
Ukongeza, ukusetyenziswa kwezipholisi ezikhethekileyo kwiinkqubo zokufudumeza iimoto zombane kukhuthaza ukudluliselwa kobushushu ngokufanelekileyo kwaye kuthintela ukugqwala, okuqinisekisa ukuthembeka kwexesha elide kunye nokusebenza kakuhle.
Njengoko iteknoloji yezithuthi zombane iqhubeka nokukhula, ezi nkqubo zokufudumeza ezintsha zinokudlala indima ebalulekileyo ekwandiseni ukwamkelwa kwabathengi kunye nokubumba ikamva lezothutho oluzinzileyo.
