Embeera y’obulamu (SOH) .
Soh ya bbaatule nayo esobola okulagibwa ng’obulamu bwayo. Obulamu bwa bbaatule busobola okwawulwamu ebika bibiri okusinziira ku mbeera ez’enjawulo ez’okukozesa: obulamu bw’okutereka n’obulamu bw’enzirukanya.
Obulamu bw’okutereka bukiikirira ebintu ebigenda bikaddiwa n’ebiva mu bbaatule mu kiseera ky’okutereka. Mu kiseera ky’okutereka, obusobozi bwa bbaatule bukendeera mu ngeri etakyukakyuka, era omuwendo gw’okufuuwa-yawukana nnyo okusinziira ku mbeera y’okutereka. N’olwekyo, okwanguwa oba okukendeeza ku sipiidi ya bbaatule kisinziira ku mbeera y’okutereka. Ebbugumu ly’okutereka nsonga nkulu ekwata ku bulamu bw’okutereka n’okwefuula -okufukirira. Bw’ogeraageranya n’ebbugumu ly’ekisenge, ebbugumu ly’okutereka bbaatule eriri waggulu lifuula enkola z’oku mabbali (nga okukulukuta) okubeera okw’enjawulo, era okufiirwa kw’ebyuma cations kuba kwa maanyi nnyo; Nga ku bbugumu eri wansi, okusaasaana kw’ebintu n’ensengekera z’amasannyalaze kukendeera, bwe kityo ne kikendeeza ku muwendo gw’okukaddiwa kwa bbaatule. Ensonga endala ekwata ku bulamu bw’okutereka bbaatule ye muwendo gwa SOC mu kiseera ky’okutereka bbaatule (wano, SOC etegeezebwa ng’omugerageranyo gwa ion ku bisannyalazo). Ku bbugumu lye limu ery’okutereka naye nga bakuba bbaatule ez’enjawulo socs, ekkubo ly’okukaddiwa kwa bbaatule lyawukana. Ku SOCs eza waggulu, obutakwatagana bwa kisannyalazo obunene buliwo ku nsengekera ya electrode/electrolyte, etumbula ensengekera z’amasannyalaze.
Obulamu bw’enkulungo bukiikirira enkosa y’okukozesa bbaatule (okusasuza n’okufulumya) ku bbaatule. Okukaddiwa kwa bbaatule kubaawo obutasalako mu kiseera ky’okucaajinga n’okufulumya. Ebbugumu n’amasannyalaze mu kiseera kya bbaatule bikozesa butereevu obulamu bw’enzirukanya. Okugatta ku ekyo, ensonga ezikwata ku bulamu bw’okutereka bbaatule nazo zikwata ku bulamu bw’enzirukanya, nga enkolagana ezikwatagana zibaawo awatali kulowooza oba bbaatule eri mu kukozesa oba mu kuwummula. Okukozesa bbaatule nkola ya exothermic; Ebbugumu lyongera okwanguya ensengekera zino, bwe kityo ne kyanguyiza okukaddiwa kwa bbaatule. Ng’oggyeeko enkyukakyuka zino, ebipimo ebikwatagana n’obulamu bw’enzirukanya (cycle life) mirimu gya mbeera ya bbaatule. Omuwendo gwa chajingi ezibula mu kiseera ky’okusiibulwa omulundi gumu (enkyukakyuka mu mbeera y’omusannyalazo) nsonga nkulu nnyo era nga kikwata nnyo ku kukaddiwa kwa bbaatule. Ekintu kino okusinga kiva ku kuvundira kw’ekisannyalazo ekirungi n’okutondebwa kwa firimu ya SEI mu kiseera ky’okucaajinga n’okufulumya eby’amaanyi mu kiseera kino-.
1. Ennyonyola y’embeera y’obulabe (SOH) mu bbaatule .
Ennyonyola ez’enjawulo ku SOH zisobola okuggibwa mu ndowooza ez’enjawulo. Mu kiseera kino, ennyonyola ezitera okukozesebwa mu kunoonyereza ku bbaatule mulimu ennyonyola y’obuziyiza obw’omunda, ennyonyola y’obuziba bw’okufulumya, n’ennyonnyola ya chajingi esigadde.
(1) Enkola y’okunnyonnyola okuziyiza munda .
Embeera y’obulamu bwa bbaatule bweyongera ng’obuziyiza bwayo obw’omunda bweyongera mpolampola. Embeera ya bbaatule (SOH) esobola okunnyonnyolwa okusinziira ku nkolagana eno:
Mu nkola eno, rnew ekiikirira okuziyiza kwa bbaatule munda mu kiseera ky’okukola; REOL ekiikirira obuziyiza obw’omunda ku nkomerero y’obulamu bwa bbaatule; era R ekiikirira resistance ya bbaatule ey’omunda mu mbeera yaayo eriwo kati.
Ekikulu mu nnyonyola eno kwe kufuna omuwendo omutuufu ku resistance ya bbaatule ey’omunda. Enkizo yaayo eva mu kupima okutuufu ennyo, naye obuzibu bwayo buli nti tetunuulira busobozi bwa bbaatule obupimiddwa, obukosebwa ennyo embeera ya bbaatule y’obulamu (SOH).
(2) Ennyonyola y’obuziba bw’okufulumya (SOH) .
Obuziba bw’okufulumya (SOH) bwa bbaatule butegeeza omugerageranyo gw’obusobozi obufuluma bbaatule okutuuka ku busobozi bwayo. Omugerageranyo guno gugeraageranye mu ngeri ey’ekifuulannenge n’emirundi bbaatule gy’esobola okuddamu okucaajinga; Kwe kugamba, obuziba bw’okufulumya gye bukoma okuba obunene, emirundi gye bukoma okujjuzaamu emirundi mitono. N’olwekyo, SOH esobola okunnyonnyolwa okuva mu ndowooza y’obuziba bw’okufulumya nga: ebitundu ku kikumi eby’omuwendo gw’okuddamu okujjuza ogusigadde ku muwendo ogusinga obunene ogw’okuddamu okujjuza ku buziba bw’okufulumya obuweereddwa.
(3) Ennyonyola y’obusobozi obusigaddewo .
Embeera ya chajingi (SOH) etegeezebwa okusinziira ku ndowooza y’obusobozi bwa bbaatule obusigaddewo. Oluvannyuma lw’okukozesa ekiseera, obusobozi bwa bbaatule obusigaddewo busobola okupimibwa butereevu. N’olwekyo, leka CNew ebeere obusobozi obusinga obunene obwa bbaatule nga tebukozesebwa, ate CNORM ebeere obusobozi obusinga okukozesebwa mu bbaatule. Olwo, SOH esobola okunnyonnyolwa nga...
