Xeetu sircuit bi méngoo ak xeetu oto bu bees bi ak gëstu simulation ak model- BMS bu sukkandiko ci liggéey. Figure 7-27 dafay wane ab modelu sircuit bu méngoo bu am batëri RC bu am structure RC, ñu koy woowe xeetu n-RC. Modèle bii amna ñatti pàcc:
1) Source voltage: ubbikug- voltage circuit bu batëri kuuraŋ bi dafay màndargaal $U_{oc}$.
2) Resistance internal Ohmik: Banneexu ci jumtukaayi electrode kuuraŋ yi, electrolyte, resistor isolation, ak yeneen mbir ñu ngi koy màndargaal ci $R_o$.
3) Reseau RC: màndarga yi am ci batëri kuuraŋ bi, lu ci melni màndarga polarisasioŋ ak jafe-jafe yi ci diffusion, dañu leen wax ci resistance polarisasioŋ $R_p$ ak capacitance polarisation $C_p$, fu $i {3}, ..., n_s$.
Ci nataal 7-27, Up dafay màndargaal voltage polarisasioŋ bu batëri kuuraŋ bi.
Buñu sukkandikoo ci sàrti voltage Kirchhoff ak yooni courant, ak lëkkaloo gi am ci digganté coppite voltage capaciteur ak courant, equation stade bi- equation bu modelu sircuit bi mën nañu ko fësal ni:
Modèle xeetu sircuit yu méngoo ak doole yu melni modelu Rin, modelu Thevenin, ak modelu Dual Polarisation (DP) dañuy nekk xeetu sircuit yu méngoo ak { {0}RC modelu sircuit bu méngoo bi n{1}, n{2}, ak n{3}}, te dañu ko jëfandikoo bu bari ci xaymab batëri ak algorithm yi.
(3) Defar ay xeeti jàngat yu bees
Xeetu jàngu masin yi soxla wuñu xam-xam ci composition bi ci biir batëri bi ak anam yi ñuy doxalee ci biir batëri bi; war nañu am done yu am solo ci batëri bi (tëmbet, voltage, tàngoor, ak ñoom seen). Ci yoon sax, dañuy taxawal fonction yu amul ligne ci diggante variable yi ci done {- yu ñuy dawal. Njariñ li gëna am solo ci xeetu model bii mooy jëfandikoo xeetu batëri yu wuute, fànnam bu baax, ak mën-mënam ngir gëna mëna jëfandikoo màndarga yi amul ligneer ci doxalinu batëri.
Ci wàllu jëfandikoo batëri kuuraŋ ak saytu, anam yi ñuy jàngee masin yi ñuy jëfandikoo dañuy gëna am logique fuzzy, reso neuronal, masin vecteur yuy jàppale, ak seeni algorithm yuñ boole. Ci weeru màrs 2016, Ndamu AlphaGo ci kaw champion bi ci Go àdduna Lee Sedol dafa dugal dundu gu bees ci jàngat bu xóot, di jur ay gëstu ak ay jëfandikoo yu bees, ñu jëfandikoo ko itam ci jëfandikoo batëri. Ak done yu doy ngir tàggat, xeetu model bii mën na am performance bu baax ci xam-xam. Waaye, xeetu mbir mi amul benn njariñ ci wàllu physique, te mënu ñu ko méngale, te limu def dafay indi jafe-jafe ci limu done yi ak kalite yi ci wàllu tàggat yaram, te loolu dafay tax ñu mëna wóolu wóolu ak dëgëraay bi suñu ko jëfandikoo ci sistemu jëfandikoo batëri.
