Indlela entsha yokuthintela iisekethe ezimfutshane

Ibhetri yeLithium inomngcipheko wesiphaluka esifutshane sangaphakathi ngenxa yenkqubo yezinto kunye neteknoloji yokuvelisa. Nangona iibhetri ze-lithium ziye zaguga ngokungqongqo kunye nokukhethwa kokuzikhupha, ngenxa yezinto ezingalindelekanga zesicelo ezifana nokungaphumeleli kwenkqubo, kusekho ukusilela okuthile ngexesha lenkqubo yesicelo, okukhokelela kwiisekethe ezimfutshane zangaphakathi. Ngokubhekiselele kwipakethi yebhetri, kukho amakhulu okanye amashumi amawaka eebhetri ze-lithium, ezonyusa kakhulu amathuba okuphuka kwebhetri. Ngenxa yogqabhuko-dubulo lwamandla aphezulu eqela, iisekethe ezimfutshane zangaphakathi zinokuthi zibangele iingozi ezimanyumnyezi, ezibangela iingozi kunye nelahleko yepropathi.

Iimveliso ze-TE’s PPTC kunye ne-MHP-TA zibonelela ngesisombululo esinokwenzeka sokuthintela ingozi embi xa kwenzeka isiphaluka esifutshane kwibhetri yombane. Ngokuphathelele imodyuli yebhethri ye-lithium-ion ehambelanayo, xa ibhetri enye okanye ngaphezulu ikhutshwe ngokukhawuleza ngexesha elifutshane, imodyuli yebhetri iya kukhutshwa, kwaye amandla ebhetri aya kubangela ukuba iqondo lokushisa ngaphakathi kwebhetri emfutshane liphakame ngokukhawuleza, enokukhokelela ngokulula ekubalekeni kwe-thermal. Ekugqibeleni yenza ukuba ibhetri igqabhuke. Jonga uMfanekiso 1.

Ukufunyaniswa kobushushu bendabuko kunokuxelela i-IC ukuba inqumle isiphaluka esiphambili xa ibhetri ishushu, kodwa ayikwazi ukuthintela ukukhutshwa okuqhubekayo ngaphakathi kwimodyuli yebhetri efanayo. Ukongezelela, ngenxa yokuba isiphaluka esiyintloko sivaliwe, onke amandla emodyuli yebhetri agxininiswe kwibhetri yangaphakathi ye-short-circuited, eyandisa amathuba okubaleka kwe-thermal. Isisombululo esifanelekileyo kukuthintela isiphaluka soqhagamshelwano phakathi kwebhetri kunye nezinye iibhetri kwimodyuli ukuba ibhetri ifunyenwe ishushu ngexesha elifutshane.

Njengoko kuboniswe kwi-Figure 2, i-TEPPTC okanye i-MHP-TA yeemveliso zechungechunge zihlanganiswe kwiyunithi enye ye-economizer. Xa isiphaluka esifutshane sangaphakathi senzeke, izixhobo zokugcina i-TE zithintela ngokufanelekileyo uxhulumaniso phakathi kwebhetri ye-short-circuit yangaphakathi kunye nezinye iibhetri kwimodyuli ukuphepha iingozi ezinzulu. Ngamandla ebhetri ye-lithium ibhetri enenani elikhulu leebhetri zeseli enye, ukuchasana kwangaphakathi kwebhetri kunye nezixhobo kufuneka zihambelane ngexesha lenkqubo yokuhlanganisana. Nangona kunjalo, ngenxa yolwakhiwo lwangaphakathi lwe-bimetallic, i-MHP-TA inobuxhakaxhaka bokumelana nesixhobo kwaye inokufikelela kwiimfuno zokumelana nebhetri ngaphakathi kubungakanani obukhulu.

Ubonelelo lwamandla e-lithium-ion I-lithium yebhetri yesekethe emfutshane iya kubangela umonakalo omkhulu, ngoko ke ugcino lwe-short-circuit yebhetri kufuneka lwenziwe. Ezi zisombululo zimbini zingentla zinokugcina ngokufanelekileyo isekethe phantsi kohlaselo olufutshane lwebhetri.
