Nibihe bikorwa bya batiri ya lithium-ion ya sisitemu yo gukurikirana bateri ya BMS?

Sisitemu yo gucunga bateri ya BMS, mubisanzwe yitwa bateri yumwana-wicaye cyangwa umuja wurugo rwa batiri, ahanini ni ukureba neza kandi ukanabika buri sisitemu ya batiri, ukirinda kwishyuza birenze urugero kandi ukanarenza urugero, ukongerera igihe cya bateri, ndetse no kukibazo cya bateri.

Sisitemu yubuyobozi bwa BMS igizwe ahanini nibice bitandukanye byunvikana, abakoresha, abagenzuzi kimwe numurongo wibimenyetso. Kugirango ushoboze amamodoka mashya yingufu zo gutwara mugihe utwaye neza kandi ukurikiza ibipimo bikwiye kandi na spes, sisitemu yo kuyobora BMS igomba kuba ijyanye nibiranga:

Ubushakashatsi bwa Batiri

Harimo imbaraga zuzuye, zose zihari, kuvumbura ingufu za batiri imwe (kugirango uhagarike ibirenze, kwishyuza birenze urugero kimwe no guhindukirira polarite), kumenya urwego rwubushyuhe (cyane cyane buri mugozi wa bateri, guhuza insinga zingenzi, nibindi bifite sisitemu yo kumva ubushyuhe), gutahura umwotsi (gukurikirana amazi ya electrolysis yamenetse, nibindi,)

Amagambo ya Leta

Harimo leta yishyurwa (SOC) cyangwa ubujyakuzimu bwo gusohora (DOD), ubuzima bwubuzima (SOH), imiterere yimiterere (SOF), imbaraga zubutegetsi (SOE), kwibeshya kimwe na leta idafite ingaruka (SOS) nibindi byinshi.

Gukemura ibibazo kumurongo

Igizwe no gushakisha amakosa, kwibeshya ubwoko bwurubanza, ikosa ryaho, ibisobanuro birambuye ibisubizo, nibindi byinshi. Kuvumbura amakosa bisobanura gukoresha ibisubizo byisesengura kugirango umenye ubwoko bwamakosa kimwe no gutanga ubwitonzi hakiri kare ukoresheje ibimenyetso byakusanyirijwe hamwe. Kunanirwa kwa Batteri bisobanura kunanirwa kwishyiriraho ibice, kunanirwa kwa actuator (nk'abahuza, abayoboke, pompe, amashanyarazi, nibindi) bya sisitemu zitandukanye nka paki za batiri, imashanyarazi yumuriro mwinshi, hamwe nubuyobozi bwumuriro, hamwe no kunanirwa kwurusobe, hamwe no gukoresha software zitandukanye mugukoresha ibikoresho byananiranye. Tegereza. Kunanirwa kw'ipaki ya batiri ubwayo bivuga hejuru ya volvoltage (overcharge), munsi ya volvoltage (overdischarge), kurenza urugero, ubushyuhe bukabije bwa ultrahigh, kunanirwa kwumuzunguruko w'imbere, guhuza ingingo, kumeneka kwa electrolyte, gusenya insulation, nibindi.

Igenzura ry'umutekano wa Bateriyeri kandi byongeye

Igizwe no kugenzura sisitemu yubushyuhe, umutekano mwinshi wumuriro wamashanyarazi no kugenzura umutekano Nyuma BMS ibonye ikosa, yigisha umugenzuzi wimodoka hamwe numuyoboro, kandi ikanasaba umugenzuzi wimodoka kubikemura neza (BMS irashobora kandi gukuraho amashanyarazi akomeye yumuriro mugihe arenze urugero runaka) kugirango birinde ubushyuhe, ubushyuhe buke, ubushyuhe burenze urugero, kurenza urugero, ndetse no gushyuha cyane. ibibazo kuri bateri kandi n'umubiri bitewe nibihari, kumeneka, nibindi kugenzura ibiciro.

Hariho ibice byo gucunga ibiciro muri BMS, bishobora kugenzura charger ya bateri kugirango yishyure bateri neza ukurikije ibiranga bateri, urwego rwubushyuhe kimwe nimbaraga za charger.

Guhuza Akagari

Kugaragara kutavuguruzanya bituma ubushobozi bwa paki ya batiri butarenze ubushobozi bwa selile ntoya mumapaki. Guhuza Batteri ni ugukoresha ingamba zoroshye cyangwa zoroshye, zitandukanya cyangwa zidatandukanya ingamba zo kuringaniza kugirango ubushobozi bwa paki ya bateri yegerejwe hafi yubushobozi bwa selile ntoya ukurikije amakuru ya selile yonyine.

Ubuyobozi bushushe

Ukurikije impamyabumenyi yubushyuhe burambuye mubipaki ya batiri ndetse no kwishyura usibye kurekura ibikenewe, hagaragajwe imbaraga zo gushyushya ingufu / gukwirakwiza ubushyuhe, kugirango hamenyekane neza ko bateri ishobora gukora kuri bumwe mubushyuhe bukwiye igihe kirekire gishoboka kandi nayo igatanga umukino wuzuye mubikorwa bya bateri.

Itumanaho

BMS isaba kwishora kumurongo nkumuyobozi ushinzwe gutwara ibinyabiziga; icyarimwe, biragoye gutandukanya BMS kumodoka, kandi irasaba kandi gukora kuri kalibrasi ya net, kugenzura, kubyara kode yikora kimwe no gukuramo porogaramu kumurongo utabanje gusenya urugero (kuzamura porogaramu utabanje gukuramo ibicuruzwa), nibindi, umuyoboro usanzwe wimodoka wemera tekinoroji ya bisi ya tekinoroji.

Icyumba cyo kubika amakuru

Ikoreshwa mukubika amakuru yingenzi, nka SOC, SOH, SOF, SOE, igiciro cyegeranijwe no gusohora Ah nimero, kode yamakosa hamwe nuburinganire, nibindi. BMS nyayo mumodoka ishobora kuba ifite porogaramu nyinshi za software hamwe nibyuma byerekanwe hejuru. Buri selire ya batiri igomba guhatanira byibuze byibuze imwe ya voltage yamashanyarazi hamwe nigice kimwe cyerekana ubushyuhe. Kuri sisitemu ya bateri ifite imitwaro myinshi ya selile, hashobora kubaho umugenzuzi umwe wa BMS, cyangwa birashoboka ko ubushobozi bwa BMS bushobora gushirwa muburyo bugenzura ibinyabiziga. Kuri sisitemu ya bateri ifite selile ibihumbi, hashobora kubaho umugenzuzi umwe hamwe nabagenzuzi benshi bakorana na module imwe gusa. Kuri buri gice cya bateri hamwe nibintu byinshi bya selile ya bateri, hashobora kuba hari module yumuzunguruko wa module kimwe nogushigikira modules, kandi nanone umugenzuzi wumugaragu yita kuri module ya bateri nka gauging voltage yiyongera kuri none, ikayobora abahuza, igahuza selile ya batiri kandi byongeye igahuza numuyoboro wogutumanaho. Ukurikije amakuru yatangajwe, umugenzuzi mukuru azakora rwose isuzuma rya leta ya batiri, gusuzuma indwara zamavuriro, gucunga ubushyuhe, nibindi.

Guhuza amashanyarazi

Bitewe n’imikoreshereze ikabije y’ikamyo y’amashanyarazi, BMS irasabwa kugira imbaraga zikomeye zo guhagarika imashanyarazi, ndetse no muri icyo gihe kimwe, BMS irahamagarirwa kugira imirasire mito yo hanze.

Nkugukurikirana kimwe nubuyobozi bwikigo gishya-gishya cyamashanyarazi yamashanyarazi, sisitemu yubuyobozi bwa BMS igomba kugenzura byimazeyo ubushyuhe bwubushyuhe, voltage, igiciro kimwe nogusohora bihari hiyongereyeho nibindi byinshi bifitanye isano na cater ya bateri mugihe nyacyo, ndetse no gufata ingamba zo gufata ingamba zihutirwa zo kurinda buri bateri yonyine mugihe bikenewe. Irinde ibibazo byumutekano nko kwishyuza birenze urugero, kurenza urugero, gushyuha cyane, hamwe n’umuzunguruko mugufi wa paki ya batiri.

Byongeye kandi, sisitemu yubuyobozi bwa BMS igomba no kugereranya neza SOC ya bateri mugihe cyose cyakemutse cyapaki ya bateri, kimwe no guhita ugarura amakuru yingenzi nko kugumaho imbaraga, urwego rwo gutwara hiyongereyeho amakosa adasanzwe kubashoferi muburyo bukwiye, kimwe no mugihe kimwe mugihe cyagenwe. Uburyo bukwiye bwo kurangiza ibikorwa byo guhanahana amakuru hagati ya sisitemu kimwe na ECU yimodoka cyangwa mudasobwa yakira.
