Batteri nyinshi za lithium zirashobora guhuzwa murukurikirane kugirango zikore ipaki ya batiri, ishobora gutanga ingufu mumitwaro itandukanye kandi irashobora no kwishyurwa mubisanzwe hamwe na charger ihuye. Batteri ya Litiyumu ntisaba sisitemu yo gucunga bateri (BMS) kwishyuza no gusezerera. None se kuki bateri zose za lithium kumasoko zongeramo BMS? Igisubizo ni umutekano no kuramba.
Sisitemu yo gucunga bateri BMS (Sisitemu yo gucunga bateri) ikoreshwa mugukurikirana no kugenzura kwishyuza no gusohora bateri zishishwa. Igikorwa cyingenzi cya sisitemu yo gucunga batiri ya lithium (BMS) nukureba ko bateri ziguma mumipaka ikora neza kandi igahita ifata ibyemezo niba bateri imwe itangiye kurenga imipaka. Niba BMS ibonye ko voltage iri hasi cyane, izahagarika umutwaro, kandi niba voltage ari ndende cyane, izahagarika charger. Bizagenzura kandi ko buri selile iri muri paki iri kuri voltage imwe kandi igabanye voltage iyo ari yo yose iruta izindi selile. Ibi byemeza ko bateri itagera kumuvuduko mwinshi cyangwa mwinshi-bikaba aribyo akenshi bitera umuriro wa batiri ya lithium tubona mumakuru. Irashobora no gukurikirana ubushyuhe bwa bateri no guhagarika ipaki ya batiri mbere yuko ishyuha cyane kuburyo idashobora gufata umuriro. Kubwibyo, sisitemu yo gucunga bateri BMS yemerera bateri kurindwa aho gushingira gusa kuri charger nziza cyangwa imikorere yukoresha neza.
Kuki mutatanga't bateri ya aside-aside ikeneye sisitemu yo gucunga bateri? Ibigize bateri ya aside-acide ntishobora gutwikwa, bigatuma badashobora gufata umuriro niba hari ikibazo cyo kwishyuza cyangwa gusohora. Ariko impamvu nyamukuru ifitanye isano nuburyo bateri yitwara mugihe yuzuye. Bateri ya aside-aside nayo igizwe na selile ihujwe murukurikirane; niba selile imwe ifite amafaranga arenze gato ayandi ma selile, izareka gusa ikigezweho kugeza izindi selile zuzuye zuzuye, mugihe gikomeza voltage yumvikana, nibindi. Muri ubu buryo, bateri ya aside-aside "iringaniza" nkuko yishyuza.
Batteri ya Litiyumu iratandukanye. Electrode nziza ya bateri ya lithium yumuriro ahanini ni ibikoresho bya lithium. Ihame ryakazi ryayo rigena ko mugihe cyo kwishyuza no gusohora, electroni ya lithium izajya ikora kumpande zombi za electrode nziza kandi mbi. Niba voltage ya selile imwe yemerewe kuba hejuru ya 4.25v (usibye na bateri ya lithium nini cyane), imiterere ya microporome ya anode irashobora gusenyuka, ibikoresho bikomeye bya kristu bishobora gukura bigatera uruziga rugufi, hanyuma ubushyuhe bukazamuka. byihuse, amaherezo biganisha ku muriro. Iyo bateri ya lithium yuzuye, voltage irazamuka gitunguranye kandi irashobora kugera kurwego rushimishije. Niba voltage ya selile runaka mumapaki ya batiri irenze iyindi selile, iyi selile izagera kuri voltage iteje akaga mugihe cyo kwishyuza. Muri iki gihe, voltage muri rusange ipaki ya batiri itaragera ku giciro cyuzuye, kandi charger ntizahagarika kwishyuza. . Kubwibyo, selile zigera kuri voltage iteje akaga bizatera ingaruka z'umutekano. Kubwibyo, kugenzura no kugenzura voltage yuzuye ya paki ya batiri ntabwo ihagije kuri chimisties ishingiye kuri lithium. BMS igomba kugenzura voltage ya buri selile igizwe na bateri.
Kubwibyo, kugirango umutekano nubuzima burebure bwa paki ya litiro, sisitemu nziza kandi yizewe yo gucunga bateri BMS irakenewe rwose.
