Nibyiza kugenzura urwego rwishyurwa buri mezi 3-6 hanyuma ukishyuza niba bigabanutse munsi ya 30%. Batteri igomba kubikwa ahantu hasukuye, humye kure yibikoresho byaka kandi hamwe na terefone zirinzwe kugirango birinde imiyoboro migufi.
Nigute ikiguzi cya LFP ikata bateri igereranya na aside - aside mugihe kirekire?
Mugihe igiciro cyambere cyo kugura bateri yo kuzamura LFP isanzwe ikubye inshuro 2 - inshuro 3 kurenza icyuma gihwanye na batiri - acide, igiciro cya nyirubwite akenshi kiri hasi mugihe kirekire. Batteri ya LFP imara inshuro 3-5 kurenza bateri ya aside-aside, igabanya amafaranga yo gusimburwa. Barasaba kandi kubungabungwa bike, kuzigama kumurimo n'ibiciro. Byongeye kandi, bateri ya LFP ifite ingufu zingirakamaro hamwe nubushobozi bwihuse bwo kwishyuza, bishobora kugabanya ingufu zingufu no kongera ibikoresho mugihe. Mubikorwa byinshi byubucuruzi, ishoramari muri bateri yo kuzamura LFP isubizwa mu myaka 2-3 binyuze muri ubwo bwizigame.
Hoba hariho uburyo budasanzwe bwo guta cyangwa gutunganya ibicuruzwa bya LFP?
Batteri ya LFP, kimwe na bateri zose za lithium - ion, zigomba gutunganywa nyuma yubuzima bwa serivisi aho kujugunywa mu myanda isanzwe. Mugihe bateri za LFP zirimo ibikoresho byuburozi buke ugereranije nizindi chimisties zimwe na zimwe za lithium (zirimo cobalt cyangwa nikel), ziracyafite ibikoresho byagaciro bishobora kugarurwa no gukoreshwa. Inkiko nyinshi zifite amabwiriza yihariye yo guta bateri ya lithium - ion, harimo na bateri yo kuzamura imikasi. Ni ngombwa gukorana n’ibicuruzwa byemewe bya batiri bikurikiza uburyo bukwiye bwo gutunganya no gutunganya ibicuruzwa kugira ngo umutekano w’ibidukikije wubahirizwe n’amabwiriza y’ibanze. Ababikora benshi nababitanga batanga gufata - gahunda yinyuma yo kurangiza - ya bateri yubuzima.
