Pamene nkhani za mphamvu zikuchulukirachulukira, kugwiritsa ntchito ndi kulimbikitsa magwero a mphamvu zongowonjezwdwa kumawoneka ngati njira yofunikira.Pakalipano, teknoloji yosungiramo mphamvu ndi nkhani yotentha kwambiri m'munda chifukwa imatha kugwiritsa ntchito matekinoloje monga mabatire achitsulo, ma supercapacitors ndi mabatire othamanga pamodzi ndi mphamvu zowonjezereka.
Monga chigawo chofunikira kwambiri mudongosolo yosungirako mphamvu (ESS), ntchito ya mabatire ndi yofunika kwambiri, makamaka ikagwiritsidwa ntchito pamagetsi omwe amatha kugwiritsa ntchito mphamvu zamagetsi.Pakati pa mapangidwe a batire yosungirako,Battery Management System (BMS)amagwira ntchito ngati ubongo ndi mthandizi, kuonetsetsa chitetezo, kuchita bwino, komanso moyo wautali wadongosolo lonse.M'nkhaniyi, tiwona kufunikira kwa BMS mu ESS ndikuwunika ntchito zake zambiri zomwe zimapangitsa kuti ikhale gawo lofunikira pakupambana kwa ntchito iliyonse yosungira mphamvu.
Kumvetsetsa BMS mu ESS:
BMS ndi kachitidwe kakang'ono kamene kamagwiritsidwa ntchito poyang'anira makina osungira batire, imayang'anira magawo monga kuyitanitsa ndi kutulutsa batri, kutentha, magetsi, SOC (State of Charge), SOH (State of Health), ndi njira zotetezera.Zolinga zazikulu za BMS ndi: choyamba, kuyang'anira momwe batire ilili kuti muzindikire zolakwika mu nthawi ndikuchitapo kanthu;chachiwiri, kuwongolera njira yolipirira ndi kutulutsa kuonetsetsa kuti batire imayimbidwa ndikutulutsidwa m'malo otetezeka ndikuchepetsa kuwonongeka ndi ukalamba;panthawi imodzimodziyo, m'pofunika kuchita kufanana kwa batri, mwachitsanzo, kusunga kugwirizana kwa ntchito ya batri mwa kusintha kusiyana kwa malipiro pakati pa munthu aliyense mu paketi ya batri;kuonjezera apo, BMS yosungirako mphamvu ikufunikanso kukhala ndi ntchito zoyankhulirana kuti zilole ntchito monga kugwirizanitsa deta ndi kulamulira kutali ndi machitidwe ena.
Ntchito Zosiyanasiyana za BMS:
1. Kuyang'anira ndi kulamulira dziko la batri: BMS yosungirako mphamvu imatha kuyang'anitsitsa magawo a batri monga magetsi, panopa, kutentha, SOC ndi SOH, komanso zina zokhudza batri.Imachita izi pogwiritsa ntchito masensa kusonkhanitsa deta ya batri.
2. SOC (State of Charge) yofanana: Pogwiritsa ntchito mapaketi a batri, nthawi zambiri pamakhala kusamvana mu SOC ya mabatire, zomwe zimapangitsa kuti ntchito ya batri iwonongeke kapena kuchititsa kuti batire iwonongeke.Energy Storage BMS imatha kuthana ndi vutoli pogwiritsa ntchito ukadaulo wa batri wofananira, mwachitsanzo, kuwongolera kutulutsa ndi kuyitanitsa pakati pa mabatire kuti SOC ya cell iliyonse ya batri ikhale yofanana.Kulinganiza kumadalira ngati mphamvu ya batri yatayika kapena kusamutsidwa pakati pa mabatire ndipo ikhoza kugawidwa m'njira ziwiri: kufananiza mopanda malire ndi kufanana kogwira ntchito.
3. Kupewa kuchulukirachulukira kapena kutulutsa: Mabatire ochulukira kapena kutulutsa ndi vuto lomwe lingachitike ndi paketi ya batri, limachepetsa mphamvu ya paketi ya batri kapenanso kupangitsa kuti isagwiritsidwe ntchito.Chifukwa chake, BMS yosungiramo mphamvu imagwiritsidwa ntchito kuwongolera mphamvu ya batri panthawi yolipira kuti iwonetsetse momwe batire ilili munthawi yeniyeni ndikuyimitsa kuyitanitsa batire ikafika pakutha kwake.
4. Onetsetsani kuyang'anitsitsa kwakutali ndi kuopsa kwa dongosolo: BMS yosungirako mphamvu imatha kutumiza deta kudzera pa intaneti yopanda zingwe ndi njira zina ndikutumiza deta yeniyeni ku malo owonetsetsa, ndipo panthawi imodzimodziyo, ikhoza kutumiza chidziwitso cha zolakwika ndi alamu nthawi ndi nthawi. malinga ndi zoikamo dongosolo.BMS imathandiziranso zida zosinthira malipoti ndi kusanthula zomwe zimatha kupanga mbiri yakale komanso mbiri ya zochitika za batri ndi dongosolo kuti zithandizire kuwunika kwa data ndikuwunika zolakwika.
5. Perekani ntchito zambiri zotetezera: BMS yosungiramo mphamvu yosungiramo mphamvu ikhoza kupereka ntchito zosiyanasiyana zotetezera kuti zisawononge mavuto monga batire yochepa-circuiting ndi over-current, ndi kuonetsetsa kulankhulana kotetezeka pakati pa zigawo za batri.Panthawi imodzimodziyo, imatha kuzindikira ndi kuthana ndi ngozi monga kulephera kwa unit ndi kulephera kwa mfundo imodzi.
6. Kuwongolera kutentha kwa batri: Kutentha kwa batri ndi chimodzi mwazinthu zofunika kwambiri zomwe zimakhudza magwiridwe antchito ndi moyo wa batri.BMS yosungira mphamvu imatha kuyang'anira kutentha kwa batri ndikuchitapo kanthu kuti iwononge kutentha kwa batri kuti kutentha kusakhale kokwera kwambiri kapena kutsika kwambiri kuti kuwononge batri.
M'malo mwake, BMS yosungiramo mphamvu imakhala ngati ubongo komanso woyang'anira njira yosungiramo mphamvu.Itha kupereka kuwunika kokwanira komanso kuwongolera machitidwe osungira mabatire kuti atsimikizire chitetezo, bata ndi magwiridwe antchito, motero amazindikira zotsatira zabwino kuchokera ku ESS.Kuonjezera apo, BMS ikhoza kupititsa patsogolo moyo ndi kudalirika kwa ESS, kuchepetsa mtengo wokonza ndi kuopsa kwa ntchito, ndikupereka njira yowonjezera yowonjezera komanso yodalirika yosungira mphamvu.
