l Umsebenzi wokulinganisa
(1) Umlinganiselo wolwazi olusisiseko: ukujonga amandla ombane ebhetri, umqondiso wangoku, kunye nobushushu bebhetri. Owona msebenzi usisiseko wenkqubo yokulawula ibhetri kukulinganisa amandla ombane, okwangoku, kunye nobushushu beeseli zebhetri, esisiseko sazo zonke izibalo ezikwinqanaba eliphezulu kunye nengqiqo yolawulo lwenkqubo yolawulo lwebhetri.
(2) Ukubona ukuxhathisa kwe-insulation: Yonke inkqubo yebhetri kunye nenkqubo ye-voltage ephezulu kufuneka ivavanyelwe ukugquma ngenkqubo yokulawula ibhetri.
(3) Ukufumanisa i-high-voltage interlock (HVIL): isetyenziselwa ukuqinisekisa ukunyaniseka kwayo yonke inkqubo ye-high-voltage. Xa ingqibelelo yesekethe ye-high-voltage system yonakaliswe, amanyathelo okhuseleko ayasebenza.
lUmsebenzi woqikelelo
(1) Uqikelelo lwe-SOC kunye ne-SOH: eyona nxalenye ingundoqo kunye neyona nto inzima
(2) Ukulinganisa: lungisa i-SOC x ukungalingani kwamandla phakathi kwee-monomers ngokusebenzisa isiphaluka sokulinganisa.
(3) Ukunciphisa amandla ebhetri: igalelo kunye namandla aphumayo ebhetri alinganiselwe kumaqondo obushushu e-SOC ahlukeneyo.

6.Uyilo lwesoftware yeBMS
lUlawulo lombane ophezulu kunye nophantsi
Xa ngokuqhelekileyo ivuliwe, i-BMS ivuswa yi-VCU ngomgca onzima okanye umqondiso we-CAN we-12V. Emva kokuba i-BMS igqibe ukuzijonga kwaye ingene kwi-standby, i-VCU ithumela umyalelo ophezulu we-voltage, kwaye i-BMS ilawula ukuvalwa kwe-relay ukugqiba uxhumano oluphezulu lwe-voltage. Xa icinyiwe, i-VCU ithumela i-low-voltage umyalelo emva koko ikhuphe i-12V yokuvuka. Xa umpu ufakwe ukutshaja kwimeko yokucima amandla, unokuvuswa ngumqondiso weCP okanye A +.
lUlawulo lokutshaja
(1) Ukutshaja kancinci
Ukutshaja okucothayo kukutshaja ibhetri ngomsinga othe ngqo oguquliweyo ukusuka kukutshintshana kwangoku yitshaja esebhodini yemfumba yokutshaja (okanye i-220V yombane). Iinkcukacha zemfumba yokutshaja ngokubanzi ziyi-16A, 32A, kunye ne-64A, kwaye inokuhlawuliswa nangobonelelo lwamandla asekhaya. I-BMS inokuvuswa ngumqondiso weCC okanye weCP, kodwa kufuneka kuqinisekiswe ukuba inokulala ngokuqhelekileyo emva kokuba ukutshaja kugqityiwe. Inkqubo yokutshaja ye-AC ilula kakhulu kwaye inokuphuhliswa ngokuhambelana nemigangatho yesizwe eneenkcukacha.
(2) Ukutshaja ngokukhawuleza
Ukutshaja ngokukhawuleza kukutshaja ibhetri ngemveliso yangoku ethe ngqo yimfumba yokutshaja yeDC, enokufikelela kwi-1C okanye inqanaba lokutshaja elingaphezulu. Ngokuqhelekileyo, i-80% yebhetri inokuhlawulwa kwimizuzu ye-45. Inokuvuswa ngumthombo wamandla ancedisayo A + umqondiso wemfumba yokutshaja.
lUmsebenzi woqikelelo
(1) I-SOP (iState of Power) ifumana ubukhulu becala ibhetri ekhoyo yokutshaja kunye nokukhupha amandla ngokujonga iitafile ngeqondo lobushushu kunye neSOC. I-VCU inquma ukuba isithuthi siphela sisetyenziswe njani ngokusekelwe kwixabiso lamandla elithunyelwe.
(2) I-SOH (iState of Health) ibonakalisa ngokukodwa imeko yempilo yangoku yebhetri, enexabiso phakathi kwe-0-100%. Kucingwa ngokubanzi ukuba ibhetri ayinakusetyenziswa emva kokuba yehle ngaphantsi kwe-80%.
(3) I-SOC (i-State of Charge) iyinxalenye ye-algorithm yolawulo oluphambili lwe-BMS, ebonisa imeko eseleyo yangoku. Isekwe ikakhulu kwindlela edityanisiweyo yeyure ye-ampere kunye ne-EKF (i-Kalman filter eyandisiweyo) i-algorithm, idityaniswe nezicwangciso zokulungisa (ezifana nokulungiswa kombane ovulekileyo, ulungiso olupheleleyo lwentlawulo, ukulungiswa kokuphela kwentlawulo, ukulungiswa komthamo phantsi kobushushu obahlukeneyo. kunye ne-SOH, njl.).
(4) I-SOE (State of Energy) i-algorithm ayiphuhliswanga ngokubanzi ngabavelisi basekhaya okanye isebenzisa i-algorithms elula ukufumana umlinganiselo wamandla aseleyo phantsi kobume bangoku ukuya kumandla aphezulu akhoyo. Lo msebenzi usetyenziswa ikakhulu ukuqikelela uluhlu oluseleyo lokuhamba ngenqanawa.
lUkuxilongwa kwempazamo
Amanqanaba ahlukeneyo eempazamo ahlukaniswa ngokwentsebenzo eyahlukeneyo yebhetri, kwaye amanyathelo ahlukeneyo okucubungula athathwa yi-BMS kunye ne-VCU phantsi kwamanqanaba ahlukeneyo eempazamo, njengezilumkiso, ukulinganiselwa kwamandla, okanye ukuchithwa ngokuthe ngqo kombane ophezulu. Iimpazamo ziquka ukufunyanwa kwedatha kunye neempazamo zengqiqo, iziphene zombane (iinzwa kunye ne-actuators), iimpazamo zonxibelelwano, kunye neempazamo zesimo sebhetri, njl.
