6.Naqshadeynta software-ka BMS
lMaareynta danab sare iyo hoose
Marka si caadi ah loo shido, BMS waxaa soo toosiya VCU iyada oo loo marayo xariiq adag ama calaamadda CAN ee 12V. Ka dib marka BMS ay is-hubiso oo ay gasho heeganka, VCU waxay dirtaa amar danab sare leh, BMS-na waxay xakamaysaa xidhitaanka gudbinta si loo dhammaystiro isku xirka danab sare leh. Marka la shido, VCU waxay dirtaa amar danab hoose leh ka dibna waxay ka goysaa toosinta 12V. Marka qoriga la geliyo si loogu dallaco xaaladda danab-daminta, waxaa soo toosin kara calaamadda CP ama A+.
lMaareynta dallacaadda
(1) Dalacsiin gaabis ah
Dalacsiin gaabis ah waa in batteriga lagu dallaco koronto toos ah oo laga beddelayo koronto beddel ah oo ay sameyso dallacaadda saaran ee tuubada dallacaadda (ama korontada 220V). Tilmaamaha tuulmada dallacaadda guud ahaan waa 16A, 32A, iyo 64A, waxaana sidoo kale lagu dallaci karaa iyada oo loo marayo koronto guri. BMS waxaa toosin kara calaamadda CC ama CP, laakiin waa in la hubiyaa inuu si caadi ah u seexan karo ka dib marka la dallaco. Habka dallacaadda AC waa mid fudud waxaana loo horumarin karaa iyadoo la raacayo heerarka qaran ee faahfaahsan.
(2) Dalacsiin degdeg ah
Dalacsiinta degdegga ah waa in batteriga lagu dallaco wax soo saar toos ah oo koronto ah iyadoo la adeegsanayo tuubada dallacaadda DC, taasoo gaari karta 1C ama xitaa heer dallacaad oo ka sarreeya. Guud ahaan, 80% batteriga waxaa lagu dallaci karaa 45 daqiiqo gudahood. Waxaa kicin kara calaamadda A+ ee isha korontada ee dheeraadka ah ee tuubada dallacaadda.
lShaqada qiyaasta
(1) SOP (Xaaladda Korontada) waxay inta badan heshaa awoodda dallacaadda iyo sii deynta ee baytariga hadda jira iyadoo fiirinaysa miisaska heerkulka iyo SOC. VCU waxay go'aamisaa sida loo isticmaalo gaariga oo dhan iyadoo lagu saleynayo qiimaha korontada ee la diray.
(2) SOH (Xaaladda Caafimaadka) waxay inta badan qeexaysaa xaaladda caafimaad ee hadda ee baytariga, iyadoo qiimaheedu u dhexeeyo 0-100%. Guud ahaan waxaa la tixgeliyaa in baytariga aan la isticmaali karin ka dib marka uu hoos uga dhaco 80%.
(3) SOC (Xaaladda Kharashaadka) waxay ka tirsan tahay algorithm-ka xakamaynta asaasiga ah ee BMS, kaas oo qeexaya xaaladda awoodda hadda jirta. Waxay inta badan ku salaysan tahay habka isku-dhafka ah ee ampere-saac iyo algorithm-ka EKF (shaandhada Kalman ee la dheereeyey), oo lagu daray xeeladaha sixitaanka (sida sixitaanka danabka wareegga furan, sixitaanka dallacaadda oo dhammaystiran, sixitaanka dallacaadda dhammaadka, sixitaanka awoodda heerkul kala duwan iyo SOH, iwm.).
(4) Algorithmka SOE (Xaaladda Tamarta) si weyn uma horumariyaan soosaarayaasha gudaha ama waxay isticmaalaan algorithm fudud si loo helo saamiga tamarta harsan ee xaaladda hadda jirta iyo tamarta ugu badan ee la heli karo. Shaqadan waxaa inta badan loo isticmaalaa in lagu qiyaaso baaxadda socodka safarka ee harsan.
lOgaanshaha cilladda
Heerarka cilladaha kala duwan waxaa lagu kala saaraa iyadoo loo eegayo waxqabadka kala duwan ee batteriga, waxaana BMS iyo VCU ay qaadaan tallaabooyin kala duwan oo wax lagu farsameeyo iyadoo la raacayo heerarka cilladaha kala duwan, sida digniinaha, xaddidaadda korontada, ama goynta tooska ah ee danabka sare. Khaladaadka waxaa ka mid ah cilladaha helitaanka xogta iyo caqliga, cilladaha korontada (dareemayaasha iyo hawl-wadeennada), cilladaha isgaarsiinta, iyo cilladaha xaaladda batteriga, iwm.
