Intshayelelo
Iiseli ze-lithium zekhemistri yeLiFePO4Ziye zathandwa kakhulu kwiintlobo ngeentlobo zezicelo kwiminyaka yakutshanje ngenxa yokuba yenye yezona khemikhali zebhetri ziqinileyo nezihlala ixesha elide ezikhoyo. Ziya kuhlala iminyaka elishumi nangaphezulu ukuba zikhathalelwa ngokuchanekileyo. Zinike ixesha lokufunda ezi ngcebiso ukuqinisekisa ukuba ufumana inkonzo ende kutyalo-mali lwakho lwebhetri.

Icebiso 1: Ungaze utshaje/ukhuphe iseli kakhulu!
Ezona zinto zibangela ukungasebenzi kakuhle kweeseli zeLiFePO4 ngaphambi kwexesha kukutshaja kakhulu kunye nokukhupha kakhulu. Nokuba yinto enye inokubangela umonakalo osisigxina kwiseli, kwaye ukusetyenziswa gwenxa okunjalo kuyayiphelisa iwaranti. Inkqubo yoKhuseleko lweBhetri iyimfuneko ukuqinisekisa ukuba akunakwenzeka ukuba nayiphi na iseli ekwipakethi yakho iphume kuluhlu lwayo oluqhelekileyo lwevolthi yokusebenza,
Kwimeko yeLiFePO4 Chemistry, ubuninzi obupheleleyo yi-4.2V ngeseli nganye, nangona kucetyiswa ukuba utshaje ukuya kwi-3.5-3.6V ngeseli nganye, kukho ngaphantsi kwe-1% yomthamo owongezelelweyo phakathi kwe-3.5V kunye ne-4.2V.

Ukutshaja kakhulu kubangela ukufudumeza ngaphakathi kwiseli kwaye ukutshaja kakhulu ixesha elide okanye kakhulu kunokubangela umlilo. I-LIAO ayithathi xanduva ngayo nayiphi na imonakalo ebangelwe kumlilo webhetri.

Ukutshaja kakhulu kunokwenzeka ngenxa yoko.

★Ukungabikho kwenkqubo yokukhusela ibhetri efanelekileyo

★Ingxaki yenkqubo yokukhusela ibhetri esulelayo

★Ukufakelwa ngendlela engafanelekanga kwenkqubo yokukhusela ibhetri

I-LIAO ayithathi uxanduva lokukhetha okanye ukusebenzisa inkqubo yokukhusela ibhetri.

Kwelinye icala lesikali, ukukhupha kakhulu kunokubangela umonakalo kwiiseli. I-BMS kufuneka ikhuphe umthwalo ukuba kukho iiseli ezisondela zingenanto (ngaphantsi kwe-2.5V). Iiseli zinokonakala kancinci ngaphantsi kwe-2.0V, kodwa zihlala zikwazi ukubuyiselwa. Nangona kunjalo, iiseli eziqhutywa zii-voltage ezingalunganga zonakala ngaphaya kokubuyiselwa.

Kwiibhetri ze-12v ukusetyenziswa kwe-low voltage cutoff kuthatha indawo ye-BMS ngokuthintela i-voltage yebhetri iyonke ukuba ingabi ngaphantsi kwe-11.5v akukho monakalo weseli ofanele ukwenzeka. Kwelinye icala ukutshaja kungabi ngaphezu kwe-14.2v akukho seli kufuneka itshajwe kakhulu.

Icebiso lesi-2: Coca iiterminal zakho ngaphambi kokuba uzifake

Iiterminals eziphezu kweebhetri zenziwe nge-aluminium kunye ne-copper, ezithi ngokuhamba kwexesha zakhe umaleko we-oxide xa zibekwe emoyeni. Ngaphambi kokufaka ii-cell interconnectors zakho kunye nee-BMS modules, hlamba ii-terminals zebhetri kakuhle ngebrashi yocingo ukuze uphelise i-oxidation. Ukuba usebenzisa ii-interconnectors ze-copper cell ezingenanto, nazo kufuneka zijongane nazo. Ukususa umaleko we-oxide kuya kuyiphucula kakhulu i-conduction kwaye kunciphise i-budding buildup kwi-terminal. (Kwiimeko ezigqithisileyo, i-burning building kwi-terminals ngenxa ye-conduction embi kuye kwaziwa ukuba inyibilikisa iplastiki ejikeleze ii-terminals kwaye yonakalisa ii-BMS modules!)

Icebiso 3: Sebenzisa izixhobo zokufakelwa zesiphelo esifanelekileyo

Iiseli zeWinston ezisebenzisa iiterminal zeM8 (90Ah nangaphezulu) kufuneka zisebenzise iibholithi ezinde ezingama-20mm. Iiseli ezineeterminal zeM6 (60Ah nangaphantsi) kufuneka zisebenzise iibholithi ezili-15mm. Ukuba uyathandabuza, linganisa ubunzulu bomsonto kwiiseli zakho kwaye uqinisekise ukuba iibholithi ziya kuba kufutshane kodwa zingafiki ezantsi komngxuma. Ukusuka phezulu ukuya ezantsi kufuneka ube ne-spring washer, i-flat washer uze ube ne-cell interconnector.

Emva kweveki okanye ngaphezulu emva kokufakelwa, jonga ukuba zonke ii-terminal bolts zakho zisaqinile na. Ii-terminal bolts ezikhululekileyo zinokubangela uqhagamshelo olunamandla, zithintele umbane we-EV yakho kwaye zibangele ukuveliswa kobushushu okungafanelekanga.

Icebiso 4: Shaja rhoqo kwaye ujikeleze kancinci

Ngeiibhetri ze-lithium, uya kufumana ubomi obude beeseli ukuba uphepha ukukhupha ulwelo olunzulu kakhulu. Sicebisa ukuba unamathele kwi-70-80% DoD (Ubunzulu bokukhupha ulwelo) ngaphandle kwakwiimeko ezingxamisekileyo.

Iiseli ezivuvukileyo

Ukudumba kuya kwenzeka kuphela xa iseli ikhutshiwe kakhulu okanye kwezinye iimeko ikhutshiwe kakhulu. Ukudumba akuthethi ukuba iseli ayisasebenzi nangona kusenokwenzeka ukuba ilahlekelwe ngamandla athile ngenxa yoko.
