Ngenxa yeempawu zeibhetri ye-lithiumngokwayo, inkqubo yolawulo lweebhetri (i-BMS) kufuneka yongezwe. Iibhetri ezingenayo inkqubo yolawulo azivumelekanga ukusetyenziswa, nto leyo eya kuba neengozi ezinkulu zokhuseleko. Ukhuseleko luhlala luyinto ephambili kwiinkqubo zeebhetri. Iibhetri, ukuba azikhuselekanga okanye azilawulwa kakuhle, zinokuba nomngcipheko wobomi obufutshane, umonakalo, okanye ukuqhuma.

I-BMS: (Inkqubo yoLawulo lweBhetri) isetyenziswa kakhulu kwiibhetri zamandla, ezifana nezithuthi zombane, iibhayisekile zombane, indawo yokugcina amandla kunye nezinye iinkqubo ezinkulu.

Imisebenzi ephambili yenkqubo yolawulo lwebhetri (i-BMS) ibandakanya i-voltage yebhetri, umlinganiselo wobushushu kunye nowangoku, ibhalansi yamandla, ukubalwa kunye nokuboniswa kwe-SOC, i-alamu engaqhelekanga, ulawulo lokutshaja kunye nokukhupha, unxibelelwano, njl.njl., ngaphandle kwemisebenzi yokukhusela esisiseko yenkqubo yokukhusela. Ezinye ii-BMS zikwadibanisa ulawulo lobushushu, ukufudumeza ibhetri, uhlalutyo lwempilo yebhetri (i-SOH), umlinganiselo wokumelana nobushushu, nokunye.

Intshayelelo kunye nohlalutyo lomsebenzi we-BMS:
1. Ukhuseleko lwebhetri, olufana ne-PCM, ukutshaja kakhulu, ukukhupha ngaphezulu, ubushushu obungaphezulu, umbane ongaphezulu, kunye nokhuseleko lwe-short circuit. Njengeebhetri eziqhelekileyo ze-lithium-manganese kunye nee-element ezintathuiibhetri ze-lithium-ion, inkqubo inqumla ngokuzenzekelayo i-charge okanye i-discharge circuit xa ifumanisa ukuba nayiphi na i-voltage yebhetri idlula i-4.2V okanye nayiphi na i-voltage yebhetri iwela ngaphantsi kwe-3.0V. Ukuba ubushushu bebhetri budlula ubushushu bokusebenza bebhetri okanye i-current idlula i-discharge current ye-battery pool, inkqubo inqumla ngokuzenzekelayo indlela yangoku ukuqinisekisa ukhuseleko lwebhetri kunye nenkqubo.

2. Ibhalansi yamandla, iyonkeibhetri, ngenxa yeebhetri ezininzi ezilandelelanayo, emva kokusebenza ixesha elithile, ngenxa yokungangqinelani kwebhetri ngokwayo, ukungangqinelani kobushushu bokusebenza kunye nezinye izizathu, ekugqibeleni kuya kubonisa umahluko omkhulu, kunempembelelo enkulu kubomi bebhetri kunye nokusetyenziswa kwenkqubo. Ibhalansi yamandla kukulungisa umahluko phakathi kweeseli nganye ukwenza itshaja esebenzayo okanye engasebenziyo okanye ulawulo lokukhupha, ukuqinisekisa ukuhambelana kwebhetri, ukwandisa ubomi bebhetri. Kukho iintlobo ezimbini zebhalansi engasebenziyo kunye nebhalansi esebenzayo kushishino. Ibhalansi engasebenziyo ikakhulu kukulinganisela ubungakanani bamandla ngokusebenzisa ukuxhathisa, ngelixa ibhalansi esebenzayo ikakhulu kukudlulisela ubungakanani bamandla ukusuka kwibhetri ukuya kwibhetri ngamandla amancinci nge-capacitor, i-inductor okanye i-transformer. I-Passive kunye ne-active equilibria zithelekiswa kwitheyibhile engasezantsi. Ngenxa yokuba inkqubo esebenzayo yokulinganisela iyinkimbinkimbi kwaye ixabiso liphezulu, eyona nto iphambili iseyi-passive equilibrium.

3. Ubalo lwe-SOC,amandla ebhetriUkubala yinxalenye ebaluleke kakhulu ye-BMS, iinkqubo ezininzi kufuneka zazi ngokuchanekileyo imeko yamandla aseleyo. Ngenxa yophuhliso lwetekhnoloji, ukubala kwe-SOC kuqokelele iindlela ezininzi, iimfuno zokuchaneka aziphezulu zinokusekelwa kwi-voltage yebhetri ukugweba amandla aseleyo, indlela echanekileyo ephambili yindlela yokudibanisa yangoku (ekwaziwa ngokuba yindlela ye-Ah), i-Q = ∫i dt, kunye nendlela yokumelana yangaphakathi, indlela yenethiwekhi ye-neural, indlela yesihluzo seKalman. Ukulinganisa kwangoku kuseyindlela ebalaseleyo kushishino.

4. Unxibelelwano. Iinkqubo ezahlukeneyo zineemfuno ezahlukeneyo zonxibelelwano. Ii-interfaces zonxibelelwano eziphambili ziquka i-SPI, i-I2C, i-CAN, i-RS485 njalo njalo. Iinkqubo zokugcina iimoto kunye namandla ikakhulu yi-CAN kunye ne-RS485.
