Iisifudumezi sebhetri yesithuthi esitsha samandlaingayigcina ibhetri kubushushu obufanelekileyo ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo yonke yesithuthi. Xa ubushushu buphantsi kakhulu, ezi lithium ion ziya kubanda, zithintele intshukumo yazo, nto leyo ebangela ukuba amandla ombane ebhetri ehle kakhulu. Ke ngoko, ebusika okanye xa ubushushu buphantsi kakhulu, kuyimfuneko ukuyifudumeza kwangaphambili ibhetri.
Inkqubo yokufudumeza iibhetri zeemoto zombane ezisebenzisa amandla amatsha isebenzisa ezi ndlela zimbini zilandelayo: ukufudumeza kwangaphambili kunye nokufudumeza amanzi ngepetroli. Ngokufaka isifudumezi sokufudumeza amanzi kwisithuthi esitsha sombane esisebenzisa amandla, ibhetri ifudunyezwa ngokudluliselwa kobushushu ukuze ifikelele kubushushu obuqhelekileyo bokusebenza.Izifudumezi zombane ezintsha ezinamandla aphezuluingadlulisela ubushushu kwibhetri yesithuthi sombane ukuze ifudumale kwangaphambili kwaye igcine kubushushu obuqhelekileyo ngokuyifakaIzifudumezi ze-PTCkwizithuthi ezintsha zombane ezisebenzisa amandla.
Isisombululo senkqubo yokufudumeza ibhetri yesithuthi esitsha esinombane ococekileyo Ebusika, ubomi bebhetri yezithuthi ezintsha zombane buyancipha kakhulu, ikakhulu kuba kumaqondo obushushu aphantsi, i-viscosity ye-electrolyte kwibhetri iyanda kwaye ukusebenza kwebhetri kunye nokutshaja kunye nokukhupha kuyehla.
Ngokwethiyori: Akuvumelekanga ukutshaja iibhetri ze-lithium kwindawo engaphantsi kwama-20 degrees Celsius (kuya kubangela umonakalo kwibhetri). Izithuthi zombane zinokusombulula ingxaki yokuncipha kwexesha lebhetri yezithuthi zombane ezintsha ezinamandla kwiindawo ezinobushushu obuphantsi ebusika ngokufaka i-isifudumezi semoto yokupakaukufudumeza kwangaphambili ipakethi yebhetri yezithuthi ezintsha zamandla ukuze ibe kubushushu obuqhelekileyo bokusebenza kwaye uphephe umonakalo kwipakethi yebhetri obangelwa kukutshaja kobushushu obuphantsi.
Isifudumezi se-PTC, esikwabizwa ngokubaInto yokufudumeza ye-PTC, yenziwe yiInto yokufudumeza ye-ceramic ye-PTCkunye netyhubhu ye-aluminiyam. Olu hlobo lwesifudumezi se-PTC luneengenelo zokumelana nobushushu obuncinci kunye nokusebenza kakuhle kokutshintshiselana kobushushu. Lubushushu obuzenzekelayo obuhlala buhleli kunye nokonga amandlaisifudumezi sombane. Uphawu olubalaseleyo lukwindlela esebenza ngayo. Oko kukuthi, xa ifeni ingaphumeleli kwaye ima, amandla e-PTC heater aya kwehla ngokuzenzekelayo kuba ayinakuchitha ubushushu obaneleyo. Ngeli xesha, ubushushu bomphezulu we-heater bugcinwa bujikeleze ubushushu beCurie (ngesiqhelo ngama-250°C) phezulu nasezantsi), ukuze kuthintelwe isiganeko "sokubomvu" kumphezulu we-heaters zombane, ezingayi kubangela ukutsha, imililo kunye nezinye iingozi ezifihlakeleyo.
Iqulathe amaphepha e-aluminium asusa ubushushu, iityhubhu ze-aluminium, amaphepha okuhambisa ubushushu, iifilimu zokuthintela ubushushu, amaphepha okufudumala e-PTC, iiterminals ze-electrode zethusi ezifakwe i-nickel kunye neeshelufu ze-electrode zeplastiki ezishushu kakhulu. Ngenxa yokusetyenziswa kwezitshisi zobushushu ezifakwa kwi-press-fit, le mveliso iphucula izinga layo lokusasaza ubushushu kwaye ithathela ingqalelo ngokupheleleyo izinto ezahlukeneyo zobushushu nezombane ze-PTC heating element ngexesha lokusebenza. Inamandla okubopha aqinileyo, ukuqhuba kakuhle kobushushu kunye nokusebenza kakuhle kokusasaza ubushushu, ukusebenza kakuhle kunye nokuthembeka. Olu hlobo lwe-PTC heater luneengenelo zokuxhathisa ubushushu obuncinci kunye nokusebenza kakuhle kokutshintshana kobushushu. Yi-heater yombane ezenzekelayo ehlala ihleli kunye nokonga umbane.
Umgaqo we-PTC heater Ukufudumeza ubushushu obuqhelekileyo I-PTC thermistor ineempawu zokufudumeza ubushushu obuqhubekayo. Umgaqo kukuba emva kokuba i-PTC thermistor ivuliwe, iyazifudumeza kwaye ixabiso lokuxhathisa lingena kwindawo yokutshintsha. Ubushushu bomphezulu we-PTC thermistor yokufudumeza ubushushu obuqhelekileyo buya kugcina ixabiso elingaguqukiyo. Ubushushu bunxulumene kuphela nobushushu beCurie be-PTC thermistor kunye ne-voltage esetyenzisiweyo, kwaye ngokusisiseko ayinanto yakwenza nobushushu obungqongileyo.
