Misingi n’enkola z’okugezesa ezisookerwako ku bbaatule z’amaanyi ze ziruwa?

Emisingi n’enkola enkulu ez’okugezesa bbaatule y’amasannyalaze .

The basic electrochemical properties of chemical power sources include capacity, voltage, internal resistance, self-discharge, storage performance, high and low temperature performance, etc. As a typical secondary chemical power source, power batteries also include charge and discharge performance, cycle performance, internal pressure, etc. Therefore, the main performance testing contents for a single power battery cell include: charge and discharge performance testing, discharge performance testing, discharge capacity and rate performance testing, high and low temperature performance testing, energy and specific energy testing, power and specific power testing, Omulimu gw’okutereka n’okwefuula-Okugezesa okuggya, okugezesa obulamu, okugezesa okuziyiza munda, okugezesa puleesa munda, n’okugezesa obukuumi, n’ebirala.

Okusinziira ku ndowooza y’okukozesa mmotoka entuufu, omuddirirwa gw’okugezesa okusaanira okukozesebwa mu mmotoka kukolebwa nga bbaatule y’amasannyalaze essiddwa ku mmotoka ez’amasannyalaze ng’ekintu eky’okugezesa, nga: okuzuula obusobozi obutakyukakyuka, okuzuula obusobozi obukyukakyuka, okugezesa okusirika, okugezesa amaanyi okutandika, okugezesa obusobozi bw’okucaajinga amangu, okugezesa obulamu bw’enzirukanya, okugezesa obukuumi, okugezesa okukankana kwa bbaatule, okuzuula amaanyi ag’oku ntikko, okuzuula okufuluma okw’ekitundu, okugezesa amaanyi agasinga obunene, okugezesa okukola kw’ebbugumu, okugezesa omulimu gw’ebbugumu, okugezesa okw’ebbugumu, okugezesa okw’ebbugumu, etc.

(1) Okuzuula obusobozi obutakyukakyuka . Ekigendererwa ekikulu eky’okugezesa kuno kwe kuzuula nti bbaatule y’amasannyalaze erina ekisannyalazo ekimala n’amaanyi ng’emmotoka ekozesebwa ddala, era esobola okukola mu ngeri eya bulijjo wansi w’emiwendo egy’enjawulo egy’okufulumya n’ebbugumu ebyalagirwa edda. Enkola enkulu ey’okugezesa kwe kugezesa okufuluma mpola wansi w’embeera y’ebbugumu etakyukakyuka, era okufulumya kukomekkerezebwa nga vvulovumenti ya bbaatule y’amasannyalaze ekka ku muwendo ogugereddwa oba obutakyukakyuka bw’obutoffaali obumu munda mu bbaatule y’amaanyi (enjawulo ya vvulovumenti) etuuka ku muwendo ogugereddwa.

(2) Okuzuula obusobozi obukyukakyuka .Mu kiseera ky’okukola mmotoka ey’amasannyalaze, ebbugumu ly’okukola n’okufulumya bbaatule y’amasannyalaze biba bya maanyi. Okugezesebwa kuno okusinga kuzuula obusobozi bwa bbaatule y’amasannyalaze mu mbeera y’okufulumya ey’amaanyi, nga kino kisinga kweyolekera mu maanyi n’obusobozi ku bbugumu ery’enjawulo n’emiwendo gy’okufulumya. Enkola enkulu ey’okugezesa kwe kukola okugezesa omutindo gw’okufulumya ku bbaatule y’amaanyi nga tukozesa profile ya current eyateekebwawo oba profile ya current ddala ekung’aanyiziddwa okuva mu kusaba kw’emmotoka. Embeera y’okukomya okugezesebwa etereezebwa okusinziira ku mbeera y’okugezesa n’engeri ya bbaatule y’amasannyalaze, naye okusinga egoberera omutindo gwa vvulovumenti okukka ku muwendo ogugere. Enkola eno esobola okulaga obutereevu era mu butuufu ebyetaago byennyini eby’okukozesa mmotoka ez’amasannyalaze.

(3) Ekigezo ekisirifu .Ekigendererwa ky’okugezesa kuno kwe kuzuula obusobozi bw’okufiirwa obusobozi bwa bbaatule y’amasannyalaze nga tebukozesebwa okumala ekiseera, ekikozesebwa okukoppa embeera ng’emmotoka ey’amasannyalaze tevuga okumala ekiseera era bbaatule n’erekebwa ng’eggule{0}}Circuit. Ekigezo ekisirifu era kimanyiddwa nga self-okufuluma n’okugezesebwa kw’omutindo gw’okutereka, ekitegeeza obusobozi bwa bbaatule okukuuma omusannyalazo gwayo oguterekeddwa wansi w’embeera z’obutonde ezimu nga kiri mu mbeera enzigule-mu circuit.

(4) Okugezesa amaanyi . Okuva amaanyi g’emmotoka agatandika bwe gali amanene ennyo, okusobola okukwatagana n’emmotoka okutandika wansi w’embeera z’ebbugumu ez’enjawulo, okugezesa kw’amaanyi okutandika kukolebwa ku bbaatule y’amasannyalaze ku bbugumu eri wansi ($−18\\text{℃}$) n’ebbugumu erya waggulu ($50\\text{℃}$). Okugezesebwa kuno, nga kwotadde tobeing epimiddwa ku bbugumu erya bulijjo, okutwalira awamu era eteekebwawo n’omuwendo gwa SOC okusobola okuzuula obusobozi bw’okufulumya bbaatule mu mbeera ez’enjawulo ez’okucaajinga. Ebigezo ebya bulijjo bye bigezo by’amaanyi ebikolebwa ku $90\\%$, $50\\%$, ne $20\\%$ SOC.

(5) Okugezesa obusobozi bw’okusasula amangu .Ekigendererwa ky’okugezesa kuno kwe kugezesa obusobozi bw’okucaajinga amangu nga bakola bbaatule ng’okola okugezesa okucaajinga okw’amaanyi-okugereka okucaajinga ku bbaatule y’amasannyalaze, n’okwekenneenya obulungi bwayo, okukola ebbugumu, n’okukosa eby’obugagga ebirala. Ku kucaajinga amangu, omutindo gwa USABC gugenderera Battery SOC okuddamu okuva ku $40\\%$ okutuuka ku $80\\%$ mu $15\\text{min}$. Mu kiseera kino, omutindo ogwateekebwawo ekibiina kya Japan ekya Chademo Association gwetaaga okusasuza bbaatule y’amasannyalaze amasannyalaze ku ssente nga $10\\text{min}$ okusobola okukakasa nti mmotoka etambula $50\\text{Km}$; Okusasula ssente ezisukka mu $30\\text{min}$ kiyinza okukakasa nti mmotoka etambula $100\\text{km}$.

(6) Okugezesa obulamu bw’obugaali .Obulamu bw’enzirukanya ya bbaatule bukosa butereevu obusobozi bw’ebyenfuna bw’okukozesa bbaatule. Obusobozi obwennyini obwa bbaatule bwe buba wansi wa $80\\%$ obw’obusobozi obusookerwako oba obusobozi obugerekebwa, bbaatule y’amasannyalaze etwalibwa ng’etuuse ku nkomerero y’obulamu bwayo. Enkola enkulu ekozesebwa mu kugezesebwa kuno kwe kukola enzirukanya y’okusannyalala n’okufulumya wansi w’embeera ezimu, nga tukozesa omuwendo gw’enzirukanya ng’omuwendo gw’obulamu bwagwo. Okuva bwe kiri nti ekiseera ky’okugezesa bbaatule y’amasannyalaze bwe ziba mpanvu, okutwalira awamu okugezesebwa kumala emyezi egiwerako oba wadde omwaka. N’olwekyo, mu nkola ey’omugaso, enkola z’okuzuula omuwendo gw’enzirukanya y’okugezesa, okupima okuvunda kw’obusobozi, n’oluvannyuma okukola linear extrapolation okusinziira ku data eno zitera okukozesebwa okugezesa. Mu kitundu ky’okunoonyereza, okusobola okukendeeza ku budde bw’okugezesa obulamu bwa bbaatule y’amaanyi, okunoonyereza era kukolebwa ku kukaddiwa kwa bbaatule okwanguya nga bongera ku bbugumu ly’okugezesa n’emiwendo gya chajingi/okufuuwa okugezesa obulamu bwa bbaatule z’amasannyalaze ne bbaatule z’amasannyalaze.

(7) Okugezesa obukuumi .Omulimu gw’obukuumi bwa bbaatule kitegeeza okwekenneenya obulabe obuyinza okubaawo eri abantu n’ebikozesebwa ebiyinza okuva ku kutereka n’okukozesa bbaatule ezitereka. Naddala nga bbaatule ekozesebwa obubi, amaanyi ag’enjawulo agayingira galeeta ebintu ebikola munda mu bbaatule okuyita mu nkola y’omubiri oba eddagala ebikola ebbugumu eddene. Singa ebbugumu teriyinza kusaasaanyizibwa mu budde, kiyinza okuvaako bbaatule okudduka ebbugumu. Ebbugumu eridduka liyinza okuvaako bbaatule okubumbulukuka, okukola omukka ogukwata omuliro, okukutuka, enjatika, n’okuwerekerwako omuliro, ekivaako obubenje obw’obukuumi. Mu nsibuko z’amaanyi ga kemiko nnyingi, obukuumi bwa bbaatule za lithium-ion kikulu nnyo. Ebintu ebya bulijjo eby’okugezesa obukuumi ku bbaatule z’amasannyalaze biragiddwa mu kipande 6-1.

Omulongooti 6-1 Ebintu ebitera okugezesa obukuumi ku bbaatule z’amasannyalaze .

(8) Okugezesa okukankana kwa bbaatule .Ekigendererwa ky’okugezesebwa kuno kwe kuzuula obuzibu bw’okukankana n’okukankana okutera okuva ku nguudo ku mutindo n’obulamu bwa bbaatule z’amasannyalaze ne bbaatule z’amasannyalaze. Okugezesebwa kw’okukankana kwa bbaatule okusinga kwekenneenya obuwangaazi bw’okukankana kwa bbaatule y’amasannyalaze (pack) era kino kikozesa ng’omusingi okulungamya okulongoosa mu dizayini y’enzimba ya bbaatule y’amasannyalaze (Pack). Waliwo ebika bibiri eby’okukankana mu kukebera okukankana: okukankana kwa sinusoidal oba okukankana okw’ekifuulannenge. Okuva power battery packs bwezisinga okukozesebwa mu mmotoka, random vibration okutwalira awamu kwettanirwa okusobola okukoppa obulungi embeera entuufu ey’okukola eya battery.

Ebyo waggulu bye bimu ku byetaago eby’awamu eby’okugezesa bbaatule z’amaanyi (packs). Ebipimo ebitongole n’ebyetaago by’okugezesa bijja kwawukana okusinziira ku kika kya bbaatule y’amasannyalaze. Omulongooti 6-2 gulaga ebyetaago by’omutindo gw’obukuumi n’enkola z’okugezesa ku bbaatule za lithium-ion n’enkola ezikozesebwa mu mmotoka ez’amasannyalaze.

Omulongooti 6-2 Ebyetaago by’omutindo gw’obukuumi n’enkola z’okugezesa ku bbaatule za lithium-ion n’enkola mu mmotoka ez’amasannyalaze .
