C-Ekitundu kye ki?

Omukozi w’ebyuma by’amakolero bwe yakyusa okuva ku lead-acid okudda ku lithium batteries mu forklifts zaabwe, runtime yagwa ebitundu 40% wadde nga obusobozi bwayo bwali bungi. Omumenyi w’amateeka teyali tekinologiya wa bbaatule-Kyali butategeera bukulu bwa miwendo gy’okufulumya n’engeri bbaatule gye zaali zisobola okutuusa amangu amaanyi mu ngeri ey’obukuumi wansi w’emigugu emizito. C-Rate esalawo oba ddala bbaatule yo eya 100AH etuusa 100 amp-essaawa z’amasoboza agakozesebwa oba ekitono ennyo, ekifuula mpozzi ennyonyola esinga obukulu bayinginiya gye babuusa amaaso obutakyukakyuka nga bakola enkola z’amasannyalaze.

C-Rate ekiikirira sipiidi bbaatule gy’efulumya oba okusaajaza okusinziira ku busobozi bwayo obusinga obunene, eraga ng’omuwendo gw’obusobozi bwa bbaatule. Omuwendo gwa 1C kitegeeza nti bbaatule etuusa obusobozi bwayo bwonna obugereddwa mu ssaawa emu yokka-kale bbaatule ya 50AH ku 1C egaba ampere 50 okumala eddakiika 60. Ekipimo kino kikola ng’olulimi olw’ensi yonna olw’okugeraageranya omulimu gwa bbaatule mu kemiko, obusobozi, n’okukozesebwa okw’enjawulo.

Omukwano gugoberera ensengekera y’okubala etereevu:

c-Rate=akasannyalazo (a) / obusobozi bwa bbaatule (AH) .

Ku nkola ya bbaatule ya 200AH efulumya ku 100 amperes, c-rate yenkana 0.5c (100A ÷ 200AH), ekitegeeza nti okufulumya okujjuvu kubaawo okusukka essaawa bbiri. Okwawukana ku ekyo, omuwendo gwa 2C ku bbaatule eyo y’emu gwetaaga ampere 400 era emaliriza okusiibulwa mu ddakiika 30. Enkolagana eno ey’ekifuulannenge wakati w’omuwendo n’obudde ereeta ekiziyiza ekikulu: C-essa ssaddaaka ekiseera ky’okudduka olw’obungi bw’amaanyi, ate wansi C-Emirundi gy’okugaziya ebbanga ly’okukola ku kugaba kwa kasasiro okukendeezeddwa.

Okutegeera c-Rate nsonga kubanga ekosa butereevu ensonga ssatu enkulu mu kulonda bbaatule: obusobozi obwennyini obusobola okukozesebwa bw’onooggyamu (emiwendo egy’oku ntikko gikendeeza ku maanyi agaliwo), okunyigirizibwa okw’ebbugumu ku bbaatule (okufuluma amangu kuleeta ebbugumu ery’omunda eriwera), era ku nkomerero obulamu bw’enzirukanya bw’oyinza okusuubira (emiwendo gy’okufulumya egy’obugwenyufu gigenda givunda). Battery epimiddwa ku 100AH ku 0.2C eyinza okutuusa 85AH yokka nga efulumiziddwa ku 2C olw’okufiirwa okw’omunda-okukendeeza ku busobozi bwa 15% ku nsonga eza bulijjo ze zitatera kulaga.

Battery chemistries ziraga obusobozi bwa C-rate obw'enjawulo ennyo. Obutoffaali bwa lithium iron phosphate (LifePO4) butera okuwagira emiwendo gy’okufulumya obutasalako egya 1-3c, nga waliwo amaanyi agamu-Enjawulo ezirongooseddwa nga zituuka ku 10c. Nickel Manganese Cobalt (NMC) Lithium-Ekyuma ekitera okukola ku 2-5C ekigenda mu maaso, ate nga tekinologiya akulembera lead-acid erwana okusukka 0.2C awatali kufiirwa kwa maanyi kwa maanyi. Enjawulo zino zisibuka mu nkyukakyuka mu buziyiza obw’omunda, ekitundu ky’obusannyalazo ku ngulu, n’okutambula kwa ion mu nkola ez’enjawulo ez’amasannyalaze.

C-rate

Ekikulukusi ky’okufulumya-Voltage okusinziira ku kiseera wansi w’akasannyalazo obutakyukakyuka-biraga engeri bbaatule ez’enjawulo gye zeeyisaamu ku c-emiwendo egy’enjawulo. Battery za lithium-zikuuma ebifaananyi bya vvulovumenti ebiwanvu ennyo ne ku miwendo gy’okufulumya egy’okugulu, nga vvulovumenti ekka nnyo okumpi n’okukendeera okujjuvu kwokka. Engeri eno esobozesa ebyuma okukola obutakyukakyuka okutuusa bbaatule lw’esemberera okukoowa.

Okutegeera .Lithium ne Battery za Alkaline .Ebifaananyi by’okusiibulwa bifuuka bikulu nga twekenneenya C-omutindo gw’okukola, nga kemiko zino ziraga enneeyisa ez’enjawulo mu musingi ezifuula okugeraageranya obutereevu okusoomoozebwa. Wadde nga obutoffaali bwa lithium bukuuma obutebenkevu bwa vvulovumenti mu bbanga lyabwo eriyinza okukozesebwa, bbaatule za alkaline ziraga okukendeera kwa vvulovumenti okutambula obutasalako mu kufulumya kwonna, ng’omulimu gukendeera nnyo ng’obwetaavu bwa kasasiro bweyongera. Ku 0.05C (omutindo gwa 20-essaawa), bbaatule za alkaline AA zituusa kumpi n’obusobozi obugereddwa. Naye, ku 1c discharge rates ezitera okubeera mu digital cameras oba high-powered flashlights, alkaline batteries ziwa ebitundu ebitakka wansi wa 30% ku mannya obusobozi olw'obuziyiza obw'omunda obw'amaanyi converting energy okudda mu heat okusinga omulimu ogw'omugaso.

Kino kinnyonnyola lwaki bbaatule za alkaline zigwa mangu mu buyinza-ebyuma enjala wadde nga amp emala-okugereka essaawa. Battery ya 2,500mAh alkaline AA mu ndowooza erina amaanyi ekyuma kya 2.5A okumala essaawa emu (1c rate), naye mu nkola etuwa 15- eddakiika 20 zokka-mu ngeri eyenkanankana ne 600-800mAh obusobozi obwennyini ku muwendo ogwo ogw’okufulumya. Okukozesa kwe kumu nga tukozesa bbaatule za lithium kwandiggyemu ebitundu 80-90% ku busobozi obugerekebwa ne ku 2C, nga kiraga lwaki lithium efuga enkola ez’okufulumya amazzi amangi wadde nga ssente nnyingi mu maaso.

lead-battery za asidi zigwa wakati w’ebisusse bino. Ku mutindo gwabwe ogwa 0.05c (essaawa 20), batuusa obusobozi bw’okutuuma amannya. Okufulumya ku 1C, era obusobozi obuliwo bukendeera okutuuka ku bitundu nga 60% ku muwendo ogugereddwa. Ekintu kino, ekyogerwako mu tteeka lya Peukert, kigera obungi bw’engeri okweyongera kw’amasannyalaze g’okufulumya gye kukendeeza ku busobozi obulungi okuyita mu kuziyiza okw’omunda okugulumivu n’ebikolwa eby’okuwunyiriza kw’okusengejja.

Ebbugumu likola nnyo ebikolwa bino. Battery za lithium zikuuma 80-90% obusobozi okutuuka ku -20℃ku kigero c-emiwendo, wadde ng’omutindo ogw’omutindo ogwa waggulu gubonaabona wansi w’okutonnya. Battery za alkaline zifiirwa obusobozi bwa 50% ku 0℃era zifuuka kumpi ezitakozesebwa wansi wa -10℃. Obusobozi bwa lead-acid bukka ebitundu nga 50% ku -18℃bw’ogeraageranya n’omutindo gw’ebbugumu ly’ekisenge.

charge c-etera okuddirira emabega w’obusobozi bw’okufulumya olw’ebiziyiza eby’obugumu n’obusannyalazo. Battery za lithium ezisinga obungi-zikkiriza emiwendo gy’okusasula 1c mu ngeri ey’obukuumi, wadde nga bbaatule nnyingi eza EV kati ziwagira 2-3c okucaajinga amangu okumala ebiseera ebimpi. Asymmetry eriwo kubanga lithium plating ku anode efuuka probable ku high charge rates ne low temperatures-A failure mode ekivaako obusobozi obw’olubeerera okufiirwa n’obulabe obuyinza okubaawo ku bukuumi.

Enzirukanya y’ebbugumu efuuka enkulu ku c-emiwendo egiri waggulu. Okufulumya bbaatule ya 100AH ku 2C (200A) okuyita mu kuziyiza okw’omunda okwa 5 milliohms kukola ebbugumu nga 200 (i2r losses: 2002 × 0.005=200W). Awatali kunyogoga kumala, ebbugumu ly’obutoffaali liyinza okulinnya diguli 30-40 waggulu w’ekifo mu ddakiika ntono, okwanguya enkola z’okuvunda n’okusobola okuleetawo ebbugumu mu butoffaali bwa lithium.

Enkola z’okuddukanya bbaatule (BMS) zikoma nnyo C-zisinziira ku sensa z’ebbugumu, embeera y’okusannyalala, n’ebyafaayo by’obutoffaali. Battery ennyogovu eyinza okukugirwa okufuluma 0.5c wadde nga 3c nameplate rating, ate ebbugumu eri waggulu livaako n’okusingawo okukendeera okukaluba okuziyiza okwonooneka. Ensalo zino ez’amaanyi zinnyonnyola lwaki EV acceleration ekendeera oluvannyuma lw’okuddiŋŋana-okutongoza amaanyi oba okucaajinga amangu-BMS ekuuma pack nga ekendeeza ku kasasiro aliwo okumala akaseera.

Obulung’amu bw’omusannyalazo era bwawukana ne C-rate. Ku 0.3C, bbaatule za lithium zitera okutuuka ku 95-98% obulungi bw’okusasuza. Ku 2C okucaajinga amangu, obulungi bukendeera okutuuka ku bitundu 85-90% nga okweyongera kw’amasannyalaze gawaliriza okukyusa amaanyi amangi okutuuka ku bbugumu. Okufiirwa kuno okw’obulungi kukulu ku bifo ebiteekebwamu enjuba n’okutereka ebyuma ebikozesa amasannyalaze ng’obulungi bw’okudda n’okudda bukwata butereevu ku by’enfuna.

Ebikwata ku bulamu bwa kalenda bitwala embeera y’okutereka, naye obulamu bw’enzirukanya businziira nnyo ku buziba bw’okufulumya n’oku c-. Battery ya lithium ebalirirwamu enzirukanya 3,000 ku 1C ne 80% mu buziba bw’okufulumya eyinza okutuuka ku cycle 1,500 zokka nga bulijjo efulumya ku 3C mu mbeera endala ezifaanagana. Okuvunda kuno kuva ku kweyongera kw’okunyigirizibwa kw’ebyuma ku nsengekera z’obusannyalazo, ensengekera z’oku mabbali ez’amangu ku busannyalazo-ensengekera z’amasannyalaze, n’ebikolwa eby’ebbugumu ebikung’aanya ku kutambula okuddiŋŋana.

Ebiwandiiko ebisembyeyo okuva mu ofiisi y’ekitongole ky’amasannyalaze mu Amerika ekola ku by’amasannyalaze biraga nti okukendeeza ku bungi bw’amazzi agafuluma okuva ku 3C okutuuka ku 1.5C mu kusaba kw’emmotoka ez’amasannyalaze kiyinza okwongera ku bulamu bwa bbaatule ebitundu 40-60%, okuvvuunula n’okwongerako mayiro 80,000-120,000 ez’enjawulo. Ku baddukanya ebidduka, okulongoosa kuno okw’obuwangaazi kutera okulaga obutuufu bwa bbaatule ennene ennyo ezikola ku C-rates entono, ekikendeeza ku mirundi gy’okukyusa n’omuwendo gwonna ogw’obwannannyini.

Omukwano si linear-Omuwendo gw'okufulumya emirundi ebiri tegumala gakendeeza ku bulamu bw'enzirukanya. Okuvunda kwanguyiza exponentially waggulu wa chemistry ezimu-emisingi egy’enjawulo. Battery za LifePO4 ziraga okweyongera okutono okw’okuvunda okuva ku 0.5C okutuuka ku 1C okukola, naye okuvunda kw’okukendeera emirundi esatu nga kukola obutasalako ku 3C. NMC Chemistries ziraga steeper degradation curves, nga obusobozi obw’amaanyi bufa okulabika waggulu wa 2C obutasalako okufuluma.

Abakola kino bakikola nga bayita mu maanyi-abalongooseddwa n’amasoboza-Endogolo z’obutoffaali ezirongooseddwa. Obutoffaali bw’amaanyi busaddaaka amaanyi agamu ag’amasoboza ag’obusannyalazo obusinga obunene, ensengekera z’okunyogoza ezinywezeddwa, n’obutonde obukyusiddwa obukwata C- buli kusannyalala okutono. Obutoffaali bw’amasoboza businga obusobozi nga tukozesa obusannyalazo obugonvu n’ebintu eby’amaanyi aga waggulu, nga bukkiriza wansi c-okugereka ng’obusuubuzi-off.

Okutegeera okubala kusobozesa okugerageranya okutuufu kwa bbaatule ku nkola ezenjawulo. Ku nkola y’okutereka amaanyi ga bbaatule eyeetaaga obusobozi bw’okufulumya 50kW okuva ku 400V nominal voltage:

Akasannyalazo aketaagisa: 50,000W ÷ 400V=125a

Bw'oba okozesa bbaatule ya 250AH: C-Weesa=125a ÷ 250ah=0.5c .

Okudduka ku mugugu guno: 1 ÷ 0.5c=2 essaawa

Okwawukana ku ekyo, obusobozi bwa bbaatule n’obudde obw’okudduka obweyagaza bwe bimanyiddwa, okukola emabega kye kisalawo obusobozi obwetaagisa. Drone eyetaaga 40A average current okumala eddakiika 15 (essaawa 0.25) okukola:

Obusobozi obutono: 40a ÷ (1 ÷ 0.25h)=40a ÷ 4c=10AH .

nga 20% safety margin era nga ebala voltage sag ku high discharge rates: 12-15AH practical minimum capacity.

Okubala obudde kugoberera enkolagana ey’okuddiŋŋana:Ebiseera (essaawa)=1 ÷ c-. A 0.2C discharge etwala essaawa 5 (1 ÷ 0.2=5h). A 5C discharge emaliriza mu ddakiika 12 (1 ÷ 5=0.2H=12 eddakiika). Okubalirira kuno kutwala embeera ennungi; Okukola kwa ddala-okwetaaga ensonga ezikendeeza ku bintu.

Ebipimo by’okufulumya omukka (pulse discharge ratings) biraga obusobozi obw’akaseera obusukka mu bipimo ebigenda mu maaso. Battery erimu 3C continuous rating eyinza okuwagira 10C okumala sekondi 10-ezikulu ku nkola nga ebikozesebwa eby’amasannyalaze oba okusannyalala kw’emmotoka ezisaba amasannyalaze amampi. Ebipimo by’okukuba (pulse ratings) mulimu ebiziyiza obudde kubanga okufuluma kw’obutoffaali okuwanvuwa waggulu-kujja kubuguma nnyo, naye ekizito ky’ebbugumu lya bbaatule kiyinza okunyiga-okutondeka ebbugumu okw’ekiseera.

Embeera y’omusango ekosa C-Rate. Ebisinga obungi ebikwata ku bbaatule bikola ku bbaatule ezijjudde; Nga bbaatule zifuluma, okuziyiza okw’omunda kulinnya era okuwangaala c-okukendeera. Battery ebalirirwamu 3C ku 100% SOC eyinza okutuusa 1.5C yokka ku 20% SOC nga tewali voltage sag esukkiridde oba akabi k’okwonooneka.

Ensengekera z’omuddiring’anwa n’ezifaanana zikaluubiriza C-okubalirira kw’omuwendo. Okuyunga bbaatule mu lunyiriri (+ ku -) kukuuma obusobozi ate nga eyongera ku vvulovumenti, n’oleka obusobozi bwa C-Rate nga tebukyusiddwa. Ebiyungo ebikwatagana (+ okutuuka ku +, - okutuuka ku -) byongerako obusobozi nga bwe bakuuma vvulovumenti, mu ngeri ennungi okukendeeza ku C-omuwendo olw’obwetaavu bwa kasasiro obuweereddwa. Battery nnya eza 50ah mu parallel zikola 200ah pack nga 100A discharge ekiikirira 0.5c mu kifo kya 2C ku butoffaali ssekinnoomu-okukendeeza ku situleesi n’okugaziya obulamu.

C-rate

EV ez’omulembe zikola okuyita mu kitundu ekigazi ekya C-omuwendo. Oluguudo oluwanvu ku sipiidi ya mayiro 65 buli ssaawa zitera okwetaaga 0.3-0.5C okuva ku bbaatule, ate okwanguya okujjuvu kuyinza okulinnya mu bufunze okutuuka ku 3-5C. Okuzza buleeki mu ngeri ey’okuzzaamu amaanyi kikyusa amasannyalaze agakulukuta, okucaajinga bbaatule ku miwendo gya 1-2c mu kiseera ky’okukendeeza ku sipiidi ey’amaanyi. Battery packs zirina okukwata ebisukkiridde bino emirundi nkumi na nkumi ku bulamu bw’emmotoka.

Tesla's Model 3 Long Range ekozesa ~75kWh battery pack nga peak discharge capability around 375kW, ekikiikirira nga 5C. Naye, BMS ekoma ku sustained high-c-okuziyiza okubuguma okusukkiridde, mu ngeri entuufu okuziyiza amaanyi ag’oku ntikko oluvannyuma lwa 10-20 seconds. Okukoma kuno kunnyonnyola lwaki emisinde egy’okusannyalala egy’enfunda eziwera giraga okukendeera kw’omulimu-enkola y’okuddukanya bbaatule mu bbugumu evudde ku pack okutuusa ebbugumu lwe likka.

Ebintu ebikozesebwa mu kucaajinga amangu bikola ku kkomo erya waggulu erya chajingi c-. A 350kW DC fast charger ekuba amaanyi mu pack ya 75kWh ekola kumpi 5C (350kW ÷ 75kWh ≈ 4.7c). Battery chemistry n'okuddukanya ebbugumu constrain sustained high-okucaajinga omuwendo; EVs ezisinga obungi taper charge rates ezisukka 80% SOC okukuuma obuwangaazi bwa battery, ne bwe kiba nti charger capacity esigalawo.

Ebikozesebwa mu maanyi ebitaliiko waya biraga ekyokulabirako waggulu-C-Rate applications ezeetaaga okukola okubutuka okwesigika. Ddereeva wa 18V impact ng’akuba ekifaananyi kya bbaatule ya 5AH 80A peak current mu biseera by’emikolo gya torque egy’amaanyi ekola ku 16C (80A ÷ 5AH). Battery erina okutuusa akasannyalazo kano okumala sekondi eziwerako buli kukozesebwa awatali kugwa kwa vvulovumenti, okuggala ebbugumu, oba okuvunda okw’amangu.

Tool Battery Packs zikozesa amaanyi-obutoffaali obulongooseddwa n’obusannyalazo obw’ekitundu eky’okungulu n’enkola ennywevu ey’okukung’aanya kati. Okulonda kwa dizayini kuno kukendeeza ku bunene bw’amasoboza nga 20% bw’ogeraageranya n’amasoboza-obutoffaali obulongooseddwa naye bisobozesa emiwendo gy’okufulumya 10-15c egy’amaanyi egy’amaanyi-egy’amaanyi ebikozesebwa. Abakola battery zino nga bakozesa voltage n’obusobozi, naye c-rate obusobozi bwawula packs ez’omutindo ogw’ekikugu okuva ku nkyusa z’abakozesa.

Utility-Okuteeka Battery ku Scale Okulongoosa ku byetaago bya C-Rate eby'enjawulo okusinziira ku kukozesa. Empeereza z’okulungamya frequency zeetaaga bbaatule ezisobola okuddamu amangu obubonero bwa giridi, nga kyetaagisa obusobozi bwa waggulu obutasalako c-rate obusobozi-mu ngeri entuufu 1-2c. Enkola zino zitambula emirundi mingi, emirundi mingi emirundi mingi buli ssaawa, ekifuula okuwangaala ku C-rates elevated paramount.

Enkozesa y’okusenya n’okusitula emigugu ku ntikko ekola ku C-eteka wansi nnyo, emirundi mingi 0.2-0.5c, okuva bwe kiri nti zifulumya mu ssaawa eziwerako mu kiseera ky’okusinga obwetaavu. Enkola zino zikulembeza obusobozi bw’amasoboza okusinga obusobozi bw’amasannyalaze, nga ziwagira obutoffaali obulongooseddwa amaanyi obusukkulumya KWh eterekeddwa buli ddoola eteekeddwamu. Enkola ya 10MWh ekoleddwa okufuluma essaawa 4 yeetaaga obusobozi bw’amaanyi ga 2.5MW bwokka (10mWh ÷ 4h), nga bukiikirira okukola kwa 0.25C.

Ensengeka z’omugatte zeeyongera okugatta waggulu-C-Teekawo bbaatule za lithium ezirina ssente entono-egula, wansi-C -okuteeka okutereka nga bbaatule ezikulukuta oba enkola z’empewo ezinyigirizibwa. Lithium ekwata enkyukakyuka ez’amangu ate enkola z’okutereka mu bungi zisobola okuwanvuwa-okukyukakyuka kw’omugugu gw’ekiseera-enkola erongoosa ebyenfuna by’enkola yonna ng’ekwataganya buli tekinologiya n’amaanyi gaayo.

Abakola ebintu batera okulongoosa obuwangaazi bwa bbaatule okwetoloola 0.5-1c emiwendo gy’okufulumya. Okukola obutakyukakyuka wansi wa 0.5c kiwa okukendeera kw’amagoba-emiwendo egy’okusiibulwa empola ennyo giwa omugaso gw’obulamu ogw’enjawulo ogw’enjawulo ogw’enjawulo. Okufuna obulamu obusinga obunene, weewale okusukka 1.5C obutasalako n’okukuuma ebbugumu erikola wakati wa 20-30℃.

Okusukka charge rated c-Rates risks lithium plating, okufiirwa obusobozi, n’obulabe bw’obukuumi. Okutambula mu bufunze waggulu katono ku bipimo kuyinza okubaawo awatali kwonooneka kwa mangu, naye emiwendo gy’ensimbi ezisukkiridde egy’olubeerera gyanguyiza okuvunda ennyo. Bulijjo goberera ebiragiro ebikwata ku kucaajinga omukozi naddala ku bbugumu erisukkiridde ng’emiwendo gy’okusasula egy’obukuumi gikendeera nnyo.

Ebbugumu eri wansi lyongera ku buziyiza obw’omunda, ne bukendeeza ku kufulumya n’okucaajinga C-omuwendo gw’omuwendo. Ku -10℃, bbaatule za lithium zitera okukola obulungi ku 50-60% ku bbugumu ly’ekisenge C-rates. Ebbugumu erya waggulu erisukka mu 45℃era ligaanyi okukendeeza ku kuziyiza okuvunda okw’amangu, wadde ng’obusobozi bw’okufulumya amangu mu butuufu bweyongera katono n’ebbugumu nga ebbugumu terinnakoma ku kuziyiza kukola.

Alkaline battery chemistry eraga resistance ya munda nnyo okusinga enkola za lithium, ekivaako okugwa kwa vvulovumenti okw’amaanyi wansi w’obwetaavu bwa current obw’amaanyi. Obuziyiza buno bukyusa amaanyi amangi mu kusaasaanya ebbugumu okusinga okukola emirimu egy’omugaso. Ku miwendo gy’okusiibulwa egisukka mu 0.5C, bbaatule za alkaline zitera okuleeta obusobozi obutasukka kitundu ku busobozi bwazo obugereddwa, ate bbaatule za lithium zikuuma obusobozi bwa bitundu 80-90% ne ku 2C.

Standard battery ratings zitera okulaga obusobozi ku kigero ekimu eky’okufulumya-Emirundi mingi 0.2c (5-Essaawa) ku lithium oba 0.05c (20-okufuluma essaawa) ku lead-Acid. Obusobozi obw’amazima obuliwo bukendeera ku miwendo egy’okusiibulwa egy’amaanyi olw’okufiirwa munda. Bulijjo kebera datasheets z'abakola ku busobozi okusinziira ku discharge rate curves okutegeera omulimu omutuufu ku application yo specific c-rate demands.

Continuous c-rate eraga akasannyalazo akasinga obunene bbaatule esobola okuyimirizaawo ekiseera ekitali kigere awatali kusukka kkomo ly’ebbugumu. Pulse C-rate Elaga nnyo short short-duration currents Battery esobola okutuusa ebiseera ebiragiddwa (mu ngeri entuufu 10- 30 seconds) nga tennaba kwetaaga budde bwa kuddamu. Pulse ratings zikakasa nti kikulu nnyo mu nkola ezirina ebyetaago eby’amaanyi amangi ebitasalako ng’okusannyalala kw’emmotoka oba okukola kw’ekintu eky’amasannyalaze.

Okulonda bbaatule entuufu kutandika n’okulaga obulungi enkola y’amaanyi g’enkola yo. Document peak current demands, average current draw, duty cycles, ne runtime eyetaagisa. Ebipimo bino bisalawo obusobozi obutono era obwetaagisa c-Obusobozi bw’omuwendo. Ekyuma ekikola average ya 5A ekigenda mu maaso nga kiriko 20A spikes okumala sekondi 2 buli sekondi 30 kyetaagisa bbaatule ekwata byombi 5A ne pulse 20A ezitasalako mu ngeri ey’obukuumi.

Ku 5A average current ku 0.5c operation: 5a ÷ 0.5c=10obusobozi obutono. Kakasa Pulse Current (20A mu kyokulabirako kino) egwa mu specification ya bbaatule erongooseddwa ey’okufulumya omukka ku 10AH pack-roughly 2C, okutwalira awamu bulungi mu busobozi bwa lithium.

Ensonga z’obutonde bwensi zeetaaga okulowoozebwako n’obwegendereza. Singa enkola ekola mu mbeera ennyogovu, derate byombi obusobozi ne c-rate obusobozi 30-50% wansi wa 0℃. Ebbugumu eriri waggulu erisukka mu 35℃warrant okulonda bbaatule nga zinywezeddwa okuddukanya ebbugumu oba okukkiriza okukendeera kw’obulamu bw’enzirukanya. Enkola ezimu ziganyulwa mu nkola z’okuddukanya ebbugumu ezikola-abawagizi, ebisiba ebbugumu, oba okunyogoza okw’amazzi-ebikuuma ebbugumu lya bbaatule mu bbanga erisinga obulungi wadde nga C-rate ekola nnyo.

Okwekenenya ebisale kulina okwekenneenya omugatte gw’ebyenfuna by’obulamu okusinga omuwendo gw’okugula okusooka gwokka. Battery ekola ku 1C eyinza okumala ebitundu 40% mu kusooka okusinga emu ekola ku 2C naye eyinza okutuusa obulamu obuwanvu ebitundu 60% ate 25% n’okusingawo amaanyi gonna okuyita mu kuyita nga tennaba kwetaaga kukyusibwa. Ku nkola ez’obusuubuzi, bala omuwendo gwa buli cycle n’omuwendo gwa buli kilowatt-essaawa etuusibwa mu bulamu bwa bbaatule yonna okuzuula ekituufu eky’ebyenfuna ekisinga obulungi.

C-Rate egerageranya sipiidi ya chajingi ya bbaatule oba okufulumya okusinziira ku busobozi, nga 1c ekiikirira okutuusa obusobozi obujjuvu mu ssaawa emu .

Battery za lithium zikuuma obusobozi bwa 80-90% ne ku 2C discharge rates, ate nga ne alkaline batteries zikka wansi wa 30% of rated capacity ku 1c olw’okuziyiza okw’omunda okusingawo .

C-Emiwendo gikola ebbugumu ery’omunda mingi, okukendeeza ku busobozi obuliwo ebitundu 5-20%, n’okwanguyiza okuvunda okuyinza okusala ku bulamu bwa bbaatule 40-60% .

Battery ezikola ku 0.5-1C zitereeza enzikiriziganya wakati w’okutuusa amasannyalaze, okukozesa amaanyi, n’okuwangaala mu nkola ezisinga obungi .

Ebbugumu likosa nnyo obukuumi c-okulongoosa -embeera ennyogovu esobola okukendeeza ku bikozesebwa c-ebitundu 40-50% ate nga byetaaga okukendeera waggulu wa 45℃.
