Bateri ya lithium ikeneye sisitemu yo kuyobora (BMS)?

Ipaki ya batiri irashobora gushirwaho muguhuza bateri nyinshi za lithium murukurikirane, zidashobora gutanga ingufu mumitwaro itandukanye gusa, ariko kandi irashobora kwishyurwa mubisanzwe hamwe na charger ihuye.Batteri ya Litiyumu ntisaba sisitemu yo gucunga bateri (BMS) kwishyuza no gusohora.None se kuki bateri zose za lithium kumasoko zongerewe na 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 nugukora ibishoboka byose kugirango bateri igume mubikorwa bikora 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, hagarika charger.Bizagenzura kandi ko buri selile iri muri paki ifite voltage imwe hanyuma ikamanura iyari hejuru yizindi selile.Ibi byemeza ko bateri itagera kuri voltage nyinshi cyangwa nkeya - ibyo bikaba aribyo bitera umuriro wa batiri ya lithium tubona mumakuru.Irashobora no gukurikirana ubushyuhe bwa bateri no guhagarika ipaki ya batiri mbere yuko ishyuha cyane igafata umuriro.Noneho, sisitemu yo gucunga bateri BMS nugukomeza kurinda bateri aho gushingira gusa kumashanyarazi meza cyangwa gukosora ibikorwa byabakoresha.

Kuberiki bidasaba bateri-acide (AGM, bateri ya gel, cycle ndende, nibindi) idasaba sisitemu yo gucunga bateri?Ibigize bateri ya aside-acide ntabwo yaka cyane kandi ntibishobora gufata umuriro niba hari ikibazo cyo kwishyuza cyangwa gusohora.Ariko impamvu nyamukuru ifitanye isano nimyitwarire mugihe bateri yuzuye.Bateri ya aside-aside nayo ikozwe mu ngirabuzimafatizo zikurikirana;niba selile imwe yashizwemo gato kurenza izindi selile, izemerera gusa amashanyarazi kurengana kugeza igihe izindi selile zuzuye zuzuye, mugihe zigumana voltage yumvikana yonyine, nibindi Batteri ifata.Muri ubu buryo, bateri ya aside-aside "kwikorera-kuringaniza" nkuko yishyuza.

Batteri ya Litiyumu iratandukanye.Electrode nziza ya batiri ya lithium yumuriro ni ibikoresho bya lithium.Ihame ryakazi ryayo rigena ko mugihe cyo kwishyuza no gusohora, electron 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 litiro nini ya lithium), imiterere ya microporome ya anode irashobora gusenyuka, ibikoresho bikomeye bya kristaline birashobora gukura bigatera uruziga rugufi, hanyuma ubushyuhe bukazamuka vuba , amaherezo bizaganisha ku muriro.Iyo selile ya lithium yuzuye, voltage izamuka gitunguranye kandi irashobora kugera kurwego rushimishije.Niba voltage ya selile iri mumapaki ya batiri irenze iyindi selile, iyi selile izabanza kugera kuri voltage iteje akaga mugihe cyo kwishyuza, kandi voltage muri rusange yamapaki ya batiri itaragera kubiciro byuzuye muriki gihe, charger izabikora ntuhagarike kwishyuza.Kubwibyo, selile yambere igeze kuri voltage iteje akaga itera umutekano.Kubwibyo, kugenzura no kugenzura voltage rusange yipaki ya batiri ntabwo ihagije kuri chimisties ishingiye kuri lithium, voltage ya buri selile kugiti cye igizwe na bateri igomba kugenzurwa na BMS.

Mubisobanuro bigufi, sisitemu yo gucunga bateri BMS ikoreshwa mukurinda paki nini za batiri.Ubusanzwe ikoreshwa ni bateri ya lithium fer fosifate, ifite imirimo yo gukingira nko kwishyuza birenze urugero, kurenza urugero, kurenza urugero, kumuzunguruko mugufi, no kuringaniza selile.Ibyambu by'itumanaho, amakuru yinjiza nibisohoka hamwe nibindi bikorwa byo kwerekana birakenewe.Kurugero, itumanaho ryimikorere ya Xinya yabigize umwuga BMS niyi ikurikira.

Mu buryo bwagutse, Akanama gashinzwe kurinda umutekano (PCB), rimwe na rimwe bita PCM (Module yo Kurinda Inzira), ni uburyo bworoshye bwo gucunga bateri BMS.Mubisanzwe bikoreshwa mubipaki bito.Mubisanzwe bikoreshwa muri bateri ya digitale, nka bateri ya terefone igendanwa, bateri ya kamera, bateri ya GPS, gushyushya bateri yimyenda, nibindi. Igihe kinini, ikoreshwa mubikoresho bya batiri 3.7V cyangwa 7.4V, kandi ifite imirimo ine yibanze yo kwishyuza, kurenza urugero, kurenza urugero, no kuzunguruka bigufi.Batteri zimwe zishobora kandi gusaba PTC na NTC.

Kubwibyo, kugirango umutekano nubuzima burebure bwa paki ya litiro, sisitemu yo gucunga bateri BMS ifite ireme ryukuri irakenewe rwose.
