Intshayelelo
LiFePO4 chemistry lithium iiseliziye zaziwa kuluhlu lwezicelo kwiminyaka yakutshanje ngenxa yokuba yenye yeyona khemistry yebhetri eyomeleleyo nehlala ixesha elide ekhoyo.Baya kuhlala iminyaka elishumi okanye ngaphezulu ukuba banyamekela ngokuchanekileyo.Thatha umzuzwana ufunde ezi ngcebiso ukuqinisekisa ukuba ufumana eyona nkonzo inde kutyalo-mali lwakho lwebhetri.

Icebiso loku-1: Ungaze uhlawule ngaphezulu/ukhuphe iseli!
Ezona zizathu zixhaphakileyo zokungaphumeleli kwangethuba kweeseli ze-LiFePO4 ziyatshaja kwaye zikhupha kakhulu.Nokuba isehlo esinye sinokubangela umonakalo osisigxina kwiseli, kwaye ukusetyenziswa kakubi okunjalo kuphelisa iwaranti.Inkqubo yoKhuseleko lweBattery iyafuneka ukuze kuqinisekiswe ukuba akunakwenzeka ukuba nayiphi na iseli ekwipakethi yakho iphume ngaphandle koluhlu lwamandla ombane osebenzayo,
Kwimeko ye-LiFePO4 Chemistry, ubuninzi obupheleleyo yi-4.2V ngeseli nganye, nangona kucetyiswa ukuba uhlawule kwi-3.5-3.6V ngeseli nganye, kukho ngaphantsi kwe-1% umthamo ongezelelweyo phakathi kwe-3.5V kunye ne-4.2V.

Ukutshaja ngaphezulu kubangela ukufudumeza ngaphakathi kweseli kunye nokutshaja ixesha elide okanye okugqithisileyo kunokubangela umlilo.I-LIAO Ayithathi xanduva ngawo nawuphi na umonakalo owenziwe ngenxa yomlilo webhetri.

Ukutshaja ngaphezulu kungenzeka ngenxa ye.

★Ukunqongophala kwenkqubo efanelekileyo yokukhusela ibhetri

★Impazamo kwinkqubo yokukhusela ibhetri eyosulelayo

★Ufakelo olungalunganga lwenkqubo yokukhusela ibhetri

I-LIAO ayithathi xanduva ngokukhetha okanye ukusebenzisa inkqubo yokukhusela ibhetri.

Kwelinye icala lesikali, ukukhupha kakhulu kunokubangela umonakalo weseli.I-BMS kufuneka ikhuphe umthwalo ukuba kukho naziphi na iiseli ezisondela zingenanto (ngaphantsi kwe-2.5V).Iiseli zinokonakaliswa kancinci ngaphantsi kwe-2.0V, kodwa zihlala zifumaneka.Nangona kunjalo, iiseli eziqhutyelwa kwii-voltages ezimbi zonakaliswa ngaphaya kokufunyanwa.

Kwiibhetri ze-12v ukusetyenziswa kwe-low voltage cutoff kuthatha indawo ye-BMS ngokuthintela umbane webhetri iyonke ukuba ihambe ngaphantsi kwe-11.5v akukho monakalo weseli kufuneka wenzeke.Kwelinye icala akutshaji ngaphezu kwe-14.2v akukho seli kufuneka itshajiswe ngaphezulu.

Icebiso lesi-2: Coca iitheminali zakho phambi kofakelo

Iitheminali eziphezu kweebhetri zenziwe nge-aluminiyam kunye nobhedu, okuthi ngokuhamba kwexesha zenze i-oxide layer xa ibekwe emoyeni.Phambi kokufaka iziqhagamshelo zeeseli zakho kunye neemodyuli ze-BMS, coca iitheminali zebhetri ngocoselelo ngebrashi yocingo ukuphelisa i-oxidation.Ukuba usebenzisa i-copper cell interconnectors ezingenanto, ezi kufuneka zijongane nazo.Ukususa umaleko we-oxide kuya kuphucula kakhulu ukuqhuba kunye nokunciphisa ukufudumala kobushushu kwi-terminal.(Kwiimeko ezigqithisileyo, ukufudumala kobushushu kwii-terminals ngenxa yokungahambi kakuhle kuye kwaziwa ngokunyibilikisa iplastiki ejikeleze ii-terminals kunye nokonakalisa iimodyuli ze-BMS!)

Icebiso lesi-3: Sebenzisa i-hardware yokufakela i-terminal efanelekileyo

Iiseli zeWinston ezisebenzisa iitheminali zeM8 (90Ah nangaphezulu) kufuneka zisebenzise iibholiti ezinde ezingama-20mm.Iiseli ezineetheminali ze-M6 (60Ah nangaphantsi) kufuneka zisebenzise iibholithi eziyi-15mm.Ukuba uyathandabuza, linganisa ubunzulu bomsonto kwiiseli zakho kwaye uqinisekise ukuba iibholithi ziya kuba kufutshane kodwa zingabethi emazantsi womngxuma.Ukusuka phezulu ukuya ezantsi kufuneka ube newasha yasentwasahlobo, iwasha eflethi emva koko i-cell interconnector.

Kwiveki okanye emva kofakelo, jonga ukuba zonke iibholithi zakho zeterminal zisaqinile.Iibholiti zetheminali ezikhululekileyo zinokubangela uqhagamshelo olunokumelana okuphezulu, ukuphanga amandla e-EV yakho kwaye kubangele ubushushu obungafanelekanga.

Icebiso lesi-4: Shaja rhoqo kunye nemijikelo engekho nzulu

Ngeiibhetri ze-lithium, uya kufumana ubomi obude beeseli ukuba uphepha ukukhutshwa okunzulu kakhulu.Sincoma ukunamathela kwi-70-80% ye-DoD (Ubunzulu bokukhutshwa) ubuninzi ngaphandle kweemeko ezingxamisekileyo.

Iiseli ezidumbileyo

Ukudumba kuya kwenzeka kuphela ukuba iseli ikhutshiwe kakhulu okanye kwezinye iimeko ishajwe kakhulu.Ukudumba akuthethi ukuba iseli ayisasebenzi nangona inokuthi iphulukane nomthamo othile ngenxa yoko.
