Ngenxa yeempawu zeibhetri ye-lithiumngokwayo, inkqubo yokulawula ibhetri (BMS) kufuneka yongezwe.Iibhetri ngaphandle kwenkqubo yokulawula zinqatshelwe ukusebenzisa, eziza kuba nemingcipheko enkulu yokhuseleko.Ukhuseleko luhlala luphambili kwiinkqubo zebhetri.Iibhetri, ukuba azikhuselwanga okanye azilawulwa kakuhle, zinokuba sengozini yobomi obufutshane, umonakalo, okanye ugqabhuko-dubulo.

I-BMS: (Inkqubo yoLawulo lweBattery) isetyenziswa kakhulu kwiibhetri zamandla, ezifana neenqwelo zombane, iibhayisikili zombane, ukugcinwa kwamandla kunye nezinye iinkqubo ezinkulu.

Imisebenzi ephambili yenkqubo yokulawula ibhetri (BMS) ibandakanya umbane webhetri, ubushushu kunye nomlinganiselo wangoku, ibhalansi yamandla, ukubala kwe-SOC kunye nokuboniswa, i-alamu engaqhelekanga, intlawulo kunye nolawulo lokukhutshwa, unxibelelwano, njl., ngaphandle kwemisebenzi yokukhusela esisiseko yenkqubo yokukhusela. .Enye i-BMS iphinda idibanise ulawulo lobushushu, ukufudumeza kwebhetri, uhlalutyo lwempilo yebhetri (SOH), umlinganiselo wokumelana nokukhusela, kunye nokunye.

Intshayelelo yomsebenzi we-BMS kunye nohlalutyo:
1. Ukukhuselwa kwebhetri, okufana ne-PCM, i-over charge, over discharge, over temperature, over current, and short circuit protection.Njengeebhetri ze-lithium-manganese eziqhelekileyo kunye nezinto ezintathuiibhetri ze-lithium-ion, inkqubo inqumla ngokuzenzekelayo intlawulo okanye isiphaluka sokukhupha xa ifumanisa ukuba nayiphi na ibhetri yebhethri idlula i-4.2V okanye nayiphi na ibhetri yebhetri iwela ngaphantsi kwe-3.0V.Ukuba ubushushu bebhetri budlula ubushushu bokusebenza kwebhetri okanye ikhoyo ngoku idlula ukukhutshwa kwangoku kwechibi lebhetri, inkqubo inqumla ngokuzenzekelayo indlela yangoku ukuqinisekisa ukhuseleko lwebhetri kunye nenkqubo.

2. Ibhalansi yamandla, iyonkeibhetri pack, ngenxa yeebhetri ezininzi kuthotho, emva kokusebenza ixesha elithile, ngenxa yokungahambelani kwebhetri ngokwayo, ukungahambelani kobushushu obusebenzayo kunye nezinye izizathu, ekugqibeleni kuya kubonisa umahluko omkhulu, kunempembelelo enkulu kubomi bomntu. ibhetri kunye nokusetyenziswa kwenkqubo.Ibhalansi yamandla kukwenza umahluko phakathi kweeseli zomntu ngamnye ukwenza enye intlawulo esebenzayo okanye engenzi nto okanye ulawulo lokukhupha, ukuqinisekisa ukuhambelana kwebhetri, ukwandisa ubomi bebhetri.Kukho iindidi ezimbini zebhalansi yokwenziwa kunye nebhalansi esebenzayo kwishishini.Ibhalansi ye-Passive ikakhulu ukulinganisa ubungakanani bamandla ngokusetyenziswa kokumelana, ngelixa ibhalansi esebenzayo ikakhulu ukuhambisa inani lamandla ukusuka kwibhetri ukuya kwibhetri elinamandla angaphantsi nge-capacitor, inductor okanye i-transformer.Ulungelelwaniso olwenziwayo nolusebenzayo luthelekiswa kwitheyibhile engezantsi.Ngenxa yokuba inkqubo ye-equilibrium esebenzayo intsonkothile kwaye neendleko ziphezulu noko, eyona nto iphambili iseyi-passive equilibrium.

3. Ubalo lweSOC,amandla ebhetriukubala yinxalenye ebaluleke kakhulu ye-BMS, iinkqubo ezininzi kufuneka zazi ngokuchanekileyo ngakumbi imeko yamandla eseleyo.Ngenxa yophuhliso lwetekhnoloji, ukubala kwe-SOC kuqokelelwe iindlela ezininzi, iimfuno ezichanekileyo aziphezulu zinokusekelwa kumbane webhetri ukugweba amandla aseleyo, eyona ndlela iphambili echanekileyo yindlela yokudibanisa yangoku (ekwabizwa ngokuba yi-Ah indlela), Q = ∫i dt, kunye nendlela yokuchasana yangaphakathi, indlela yenethiwekhi ye-neural, indlela yokucoca i-Kalman.Amanqaku angoku kuseyeyona ndlela iphambili kushishino.

4. Unxibelelwano.Iinkqubo ezahlukeneyo zineemfuno ezahlukeneyo zonxibelelwano lonxibelelwano.Unxibelelwano oluqhelekileyo lonxibelelwano lubandakanya iSPI, I2C, CAN, RS485 njalo njalo.Iinkqubo zemoto kunye nokugcinwa kwamandla ikakhulu yi-CAN kunye ne-RS485.
