Maxaa dhacaya Marka BMS-gu guuldareysto?

Nidaamka Maareynta baytariga (BMS) ayaa door muhiim ah ka ciyaara hubinta badbaadada iyo hawl qabadka baytariyada lithium-ion, oo ay ku jiraan LFP iyo baytariyada ternary lithium (NCM/NCA). Ujeeddadeeda koowaad waa in la kormeero oo la habeeyo cabbirrada baytariyada kala duwan, sida danabka, heerkulka, iyo hadda, si loo hubiyo in batteriga uu ku shaqeeyo gudaha xadka badbaadada leh. BMS waxa kale oo ay batteriga ka ilaalisaa in lagu dallaco, si xad dhaaf ah loo shubo, ama u shaqeeyo meel ka baxsan heerkulkiisa ugu fiican. Xirmooyinka baytariga oo leh unugyo taxane ah oo badan (xadhkaha baytariga), BMS waxay maamushaa isu dheellitirka unugyada gaarka ah. Marka BMS uu fashilmo, batteriga ayaa laga tagayaa mid nugul, cawaaqibta ka dhalan kartana waxay noqon kartaa mid daran.

1. Dallacaadda xad-dhaafka ah ama ka-saarista

Mid ka mid ah hawlaha ugu muhiimsan ee BMS waa ka hortagga in batteriga lagu dallaco ama si xad dhaaf ah loo sii daayo. Dallacaadda xad-dhaafka ah waxay si gaar ah khatar ugu tahay baytariyada cufnaanta tamarta-sare leh sida ternary lithium (NCM/NCA) sababtoo ah waxay u nuglaadaan ka cararka kulaylka. Tani waxay dhacdaa marka korantada batarigu dhaafo xadka badbaadada leh, taasoo dhalinaysa kulayl xad dhaaf ah, taasoo keeni karta qarax ama dab. Siidaynta xad-dhaafka ah, dhanka kale, waxay u keeni kartaa dhaawac joogto ah unugyada, gaar ahaan baytariyada LFP, kuwaas oo lumin kara awoodda iyo muujinta waxqabadka liita ka dib dheecaan qoto dheer. Labada noocba, BMS ku guul darradeeda inay habayso tamarta korantada inta lagu jiro dallacaadda iyo sii daynta waxay keeni kartaa dhaawac aan laga soo kaban karin oo ku yimaadda batteriga.

2. Kulayl xad dhaaf ah iyo kulaylka ka cararaya

Baytariyada ternary lithium (NCM/NCA) waxay si gaar ah ugu nugul yihiin heerkulka sare, si ka badan baytariyada LFP, kuwaas oo loo yaqaan xasilloonida kulaylka. Si kastaba ha ahaatee, labada noocba waxay u baahan yihiin maaraynta heerkulka taxaddar leh. BMS shaqaynaysa ayaa la socota heerkulka batteriga, isaga oo hubinaya inuu ku jiro meel badbaado leh. Haddii BMS ku guuldareysto, kulayl xad dhaaf ah ayaa dhici kara, taasoo kicinaysa falcelinta silsiladda khatarta ah ee loo yaqaan 'thermal runaway'. Baakidh batari ah oo ka kooban unugyo taxane ah oo badan (xadhkaha baytari), ka cararka kulaylku wuxuu si degdeg ah uga faa'iidaysan karaa hal unug ilaa kan xiga, taasoo u horseedaysa fashilaad musiibo ah. Codsiyada korantada sare sida baabuurta korantada, khatartan waa la weyneeyey sababtoo ah cufnaanta tamarta iyo tirada unuggu aad bay u badan yihiin, taasoo kordhinaysa suurtagalnimada cawaaqib xumo.

3. Isku dheelitir la'aanta u dhaxaysa Unugyada baytariga

Xirmooyinka baytariyada unugyada badan, gaar ahaan kuwa leh qaabaynta korantada sare sida baabuurta korontada, isku dheellitirnaanta tamarta u dhexeysa unugyada ayaa muhiim ah. BMS ayaa mas'uul ka ah in ay hubiso in dhammaan unugyada ku jira xirmada ay isku dheeli tiran yihiin. Haddii BMS-du ay fashilanto, unugyada qaar ayaa laga yaabaa in la kordhiyo halka kuwa kalena ay ku jiraan kharash yar. Nidaamyada leh xadhkaha batariyada badan, dheelitir la'aantani kaliya ma dhimayso waxtarka guud ee waxay sidoo kale keenaysaa khatar badbaado. Unugyada culeyska badan gaar ahaan waxay halis ugu jiraan kulayl xad dhaaf ah, taasoo keeni karta inay si xun u fashilmaan.

4. Luminta Kormeerka iyo Diiwaangelinta Xogta

Nidaamyada baytariyada adag, sida kuwa loo isticmaalo kaydinta tamarta ama baabuurta korontada, BMS waxay si joogto ah ula socotaa waxqabadka batteriga, kaydinta xogta wareegyada lacag bixinta, tamarta, heerkulka, iyo caafimaadka unugyada shakhsi ahaaneed. Macluumaadkan ayaa muhiim u ah fahamka caafimaadka xirmooyinka batteriga. Marka BMS-du fashilanto, kormeerkan muhiimka ahi wuu joogsadaa, taas oo ka dhigaysa mid aan suurtogal ahayn in la ogaado sida ugu wanaagsan ee unugyada xirmada ay u shaqeeyaan. Nidaamyada baytariga tamarta sare leh ee leh unugyo taxane ah oo badan, awood la'aanta la socodka caafimaadka unuggu waxay u horseedi kartaa guuldarrooyin lama filaan ah, sida korontadu si lama filaan ah u lumiso ama dhacdooyinka kulaylka.

5. Awood la'aanta ama waxtarka oo yaraada

BMS-ga guuldarraystay wuxuu keeni karaa hoos u dhaca waxtarka ama xitaa wadarta guud ee korontadu. Iyadoo aan si habboon loo maamulindanab, heerkulka, iyo dheellitirka unugga, nidaamka ayaa laga yaabaa inuu xirmo si looga hortago waxyeello kale. Codsiyada halkaxadhkaha batari-sareku lug leh, sida baabuurta korantada ama kaydinta tamarta warshadaha, tani waxay keeni kartaa luminta korantada si lama filaan ah, taasoo keenaysa khataro badbaado oo weyn. Tusaale ahaan, aternary lithiumbaakadda baytarigu waxa laga yaabaa inay si lama filaan ah u xidho inta gaadhi koronto ku socdo, taas oo abuuraysa xaalado wadista oo khatar ah.
