Bitewe n'ibirangabatiri ya lithiumubwayo, sisitemu yo gucunga bateri (BMS) igomba kongerwamo.Batteri idafite sisitemu yo kuyobora irabujijwe gukoresha, izaba ifite ingaruka zikomeye z'umutekano.Umutekano uhora wibanze kuri sisitemu ya batiri.Batteri, niba idakingiwe neza cyangwa igacungwa, irashobora kugira ibyago byo kubaho igihe gito, kwangirika, cyangwa guturika.

BMS: (Sisitemu yo gucunga Bateri) ikoreshwa cyane cyane muri bateri z'amashanyarazi, nk'ibinyabiziga by'amashanyarazi, amagare y'amashanyarazi, kubika ingufu n'ubundi buryo bunini.

Ibikorwa nyamukuru bya sisitemu yo gucunga bateri (BMS) harimo voltage ya batiri, ubushyuhe nigipimo kigezweho, kuringaniza ingufu, kubara SOC no kwerekana, gutabaza bidasanzwe, kwishyuza no gusohora imiyoborere, itumanaho, nibindi, usibye ibikorwa byibanze byo kurinda sisitemu yo kurinda .BMS zimwe nazo zihuza imicungire yubushyuhe, gushyushya bateri, ubuzima bwa bateri (SOH), gupima kurwanya insulation, nibindi byinshi.

Imikorere ya BMS no gusesengura:
1. Kurinda bateri, bisa na PCM, hejuru yishyurwa, hejuru yisohoka, hejuru yubushyuhe, hejuru yubu, no kurinda imiyoboro ngufi.Nka bateri zisanzwe za lithium-manganese nibintu bitatubateri ya lithium-ion, sisitemu ihita ihagarika umuriro cyangwa gusohora uruziga rumaze kubona ko ingufu za bateri zose zirenga 4.2V cyangwa ingufu za bateri zose zigwa munsi ya 3.0V.Niba ubushyuhe bwa bateri burenze ubushyuhe bwimikorere ya bateri cyangwa ikigezweho kirenze isohoka rya pisine ya batiri, sisitemu ihita ihagarika inzira igezweho kugirango umutekano wa bateri numutekano wa sisitemu.

2. Impirimbanyi zingufu, zoseipaki, kubera bateri nyinshi murukurikirane, nyuma yo gukora mugihe runaka, kubera kudahuza kwa bateri ubwayo, kudahuza ubushyuhe bwakazi nizindi mpamvu, amaherezo bizerekana itandukaniro rinini, bifite ingaruka nini mubuzima bwa bateri no gukoresha sisitemu.Ingufu zingirakamaro nugukosora itandukaniro riri hagati yutugingo ngengabuzima kugirango dukore ibintu bimwe na bimwe bikora cyangwa byoroshye cyangwa gucunga ibicuruzwa, kugirango harebwe niba bateri ihoraho, ikongerera igihe cya bateri.Hariho ubwoko bubiri bwo kuringaniza no kuringaniza mubikorwa.Impirimbanyi ya pasiporo ni ukuringaniza ingufu nyinshi binyuze mukurwanya, mugihe impirimbanyi ikora cyane cyane kwimura ingufu ziva muri bateri kuri bateri hamwe nimbaraga nke binyuze muri capacitor, inductor cyangwa transformateur.Passive kandi ikora iringaniza igereranwa nimbonerahamwe ikurikira.Kuberako sisitemu ikora iringaniza igoye kandi igiciro ni kinini, inzira nyamukuru iracyari passique iringaniye.

3. Kubara SOC,ingufu za batirikubara nigice cyingenzi cyane cya BMS, sisitemu nyinshi zigomba kumenya neza uko imbaraga zisigaye.Bitewe niterambere ryikoranabuhanga, kubara SOC byakusanyije uburyo bwinshi, ibisabwa neza ntabwo biri hejuru birashobora gushingira kumashanyarazi ya bateri kugirango harebwe ingufu zisigaye, uburyo nyamukuru nyabwo nuburyo bwo guhuza ubu (bizwi kandi nuburyo Ah), Q = ∫i dt, kimwe nuburyo bwo kurwanya imbere, uburyo bwurusobe rwuburyo, Kalman muyunguruzi.Gutanga amanota yubu nuburyo bwiganje mu nganda.

4. Itumanaho.Sisitemu zitandukanye zifite ibisabwa bitandukanye muburyo bwitumanaho.Inzira nyamukuru itumanaho irimo SPI, I2C, CAN, RS485 nibindi.Sisitemu yo kubika ibinyabiziga ningufu ni CAN na RS485.
