Indlela entsha yokuvimbela amasekethe amafushane

Ibhethri ye-lithium inobungozi bokujikeleza okufushane kwangaphakathi ngenxa yesistimu yezinto ezibonakalayo kanye nobuchwepheshe bokukhiqiza. Nakuba amabhethri e-lithium athole ukuguga okuqinile kanye nokukhetha ukuzikhipha, ngenxa yezici zohlelo lokusebenza ezingalindelekile ezifana nokwehluleka kwenqubo, kusekhona ukwehluleka okuthile phakathi nenqubo yesicelo, okuholela kumasekhethi amafushane angaphakathi. Ngokuqondene nephakethe lebhethri, kukhona amakhulu noma amashumi ezinkulungwane zamabhethri e-lithium, okwandisa kakhulu amathuba okuphuka kwephakethe lebhethri. Ngenxa yokuqhuma kwamandla eqembu lamandla aphezulu, ama-short circuits angaphakathi angase adale izingozi ezimbi, ezidala ukulimala nokulahlekelwa kwempahla.

Imikhiqizo ye-TE’s PPTC kanye ne-MHP-TA ihlinzeka ngesixazululo esingaba khona sokuvimbela ingozi embi uma kwenzeka kuba nesekethe emfishane ebhethrini likagesi. Ngokuqondene ne-parallel lithium-ion power lithium battery module, lapho ibhethri elilodwa noma amaningi ekhishwa ngokuzumayo ngesikhathi esifushane, imodyuli yebhethri yebhethri izophuma, futhi amandla ebhethri azobangela izinga lokushisa ngaphakathi kwebhethri elifushane likhuphuke ngokushesha, okungaholela kalula ekubalekeni okushisayo. Ekugcineni yenza ukuthi ibhethri liqhume. Bheka Umfanekiso 1.

Ukutholwa kwezinga lokushisa okujwayelekile kungatshela i-IC ukuthi inqamule isekethe eyinhloko lapho ibhethri ishisa, kodwa ngeke ivimbele ukuphuma okuqhubekayo ngaphakathi kwemojuli yebhethri ehambisanayo. Ukwengeza, ngenxa yokuthi isifunda esiyinhloko sivinjiwe, wonke amandla emojula yebhethri agxilwe ebhethri yangaphakathi ye-short-circuited, okwandisa amathuba okubaleka okushisayo. Isixazululo esikahle ukuvimba umjikelezo wokuxhuma phakathi kwebhethri namanye amabhethri kumojula uma ibhethri litholakala lishisa ngesikhathi esifushane.

Njengoba kuboniswe kuMfanekiso 2, imikhiqizo yochungechunge lwe-TEPPTC noma ye-MHP-TA ihlanganiswa kuyunithi eyodwa yezomnotho. Uma kwenzeka isifunda esifushane sangaphakathi, okokusebenza kokulungisa kwe-TE kuvimbela ngempumelelo ukuxhumana phakathi kwebhethri le-short-circuit yangaphakathi namanye amabhethri kumojula ukugwema izingozi ezimbi. Ngamandla webhethri ye-lithium amaphakethe anenani elikhulu lamabhethri eseli elilodwa, ukumelana kwangaphakathi kwebhethri nezinto zokusebenza kuyadingeka ukuze kuhambisane ngesikhathi senqubo yokuhlanganisa. Nokho, ngenxa yesakhiwo sayo sangaphakathi se-bimetallic, i-MHP-TA inokungaguquguquki okuhle kokumelana nedivayisi futhi ingahlangabezana nezimfuneko zokumelana nebhethri kwangaphakathi ngokwezinga elikhulu.

I-lithium-ion power supply Lithium battery short circuit izodala umonakalo omkhulu, ngakho-ke ukugcinwa kwebhethri okufushane kufanele kwenziwe. Izixazululo ezimbili ezingenhla zingagcina kahle isekethe ngaphansi kokuhlasela kwebhethri okufushane.
