C-rate ya bbaatule eri etya?

C-rate ya bbaatule ye yuniti egera sipiidi y’okucaajinga oba okufulumya bbaatule, era emanyiddwa nga charge/discharge rate. Okusingira ddala, C-rate ekiikirira enkolagana ey’emirundi mingi wakati wa bbaatule ya chajingi/afulumyayo n’obusobozi bwayo obugereddwa. Enkola y’okubalirira eri nti:

Omuwendo gw'okusaajaza/Okufulumya = Okusasula/Okufulumya Akasannyalazo / Obusobozi Obugereddwa .

Ennyonyola n’okutegeera C-rate .

• Ennyonyola: C-rate, era eyitibwa charge/discharge rate, gwe mugerageranyo gwa charge/discharge current ku busobozi obw’erinnya bwa bbaatule. Okugeza, ku bbaatule erimu obusobozi obugerekeddwa obwa 100AH, okufulumya ku current ya 20A kikwatagana n’omuwendo gw’okufulumya 0.2C.

• Okutegeera: C-rate efuluma, nga 1c, 2c, oba 0.2c, eraga sipiidi y’okufulumya. Omutindo gwa 1c kitegeeza nti bbaatule esobola okufuluma mu bujjuvu mu ssaawa emu, ate 0.2c eraga nti efuluma mu ssaawa ttaano. Okutwalira awamu, amasannyalaze ag’enjawulo agafuluma gasobola okukozesebwa okupima obusobozi bwa bbaatule. Ku bbaatule ya 24AH, akasannyalazo akafulumya aka 2C kali 48A, ate akasannyalazo akafulumya aka 0.5C kali 12A.

Okukozesa C-RATE .

• Okugezesa omutindo: Nga tufulumya ku C-rates ez’enjawulo, kisoboka okugezesa ebipimo bya bbaatule ng’obusobozi, okuziyiza okw’omunda, n’omukutu gw’okufulumya, ekiyamba okwekenneenya omutindo gwa bbaatule n’obulamu.

• Enkola z‟okukozesa: Enkola ez‟enjawulo ez‟okukozesa zirina ebyetaago bya C-rate eby‟enjawulo. Okugeza, emmotoka ez’amasannyalaze zeetaaga bbaatule za C-rate enkulu okusobola okucaajinga amangu/okuzifulumya, ate enkola z’okutereka amaanyi zikulembeza obulamu obuwanvu n’omuwendo, emirundi mingi zilonda okucaajinga n’okugifulumya mu C-rate entono.

Ensonga ezikwata ku C-rate .

Omulimu gw'obutoffaali .

• Obusobozi bw’obutoffaali: C-rate mu bukulu ye ratio ya charge/discharge current ku cell rated capacity. Bwe kityo, obusobozi bw’obutoffaali busalawo butereevu C-rate. Obusobozi bw’obutoffaali gye bukoma okuba obunene, c-rate gyekoma okuba wansi ku current y’emu ey’okufulumya, ne vice versa.

• Ebintu by’obutoffaali n’ensengekera: ebikozesebwa n’ensengekera y’obutoffaali, omuli ebikozesebwa mu busannyalazo, n’ekika kya electrolyte, bifuga omulimu gwa chajingi/okufuuwa era bwe bityo ne bikosa C-rate. Ebintu ebimu biyinza okuwagira okucaajinga n’okubifulumya mu ngeri ey’omutindo ogwa waggulu, ate ebirala biyinza okutuukira ddala ku kukozesebwa okw’omuwendo omutono.

Design ya Battery Pack .

• Enzirukanya y’ebbugumu: Mu kiseera kya chajingi/ekifulumya, bbaatule ekola ebbugumu ery’amaanyi. Singa enzirukanya y’ebbugumu temala, ebbugumu ery’omunda lijja kulinnya, okukomya amaanyi g’ekisannyalazo n’okukosa C-rate. N’olwekyo, dizayini ennungi ey’ebbugumu kikulu nnyo mu kwongera ku C-rate ya bbaatule.

• Battery Monitoring System (BMS) : BMS erondoola era eddukanya bbaatule, omuli okufuga charge/discharge, ebbugumu, n’ebirala nga bafuga bulungi charge/discharge current ne voltage, BMS erongoosa omutindo gwa bbaatule, bwe kityo ne kilongoosa C-rate.

Embeera ez’ebweru .

• Ebbugumu eribeera mu kifo: Ebbugumu ly’obutonde kye kintu ekikulu mu kukola bbaatule. Mu bbugumu eri wansi, sipiidi y’okucaajinga ekendeera, era obusobozi bw’okufulumya buziyizibwa, ekikendeeza ku C-rate. Okwawukana ku ekyo, mu bbugumu erya waggulu, okubuguma okusukkiridde nakyo kisobola okukosa C-rate.

• Embeera ya bbaatule (SOC): SoC ya bbaatule bw’eba ntono, okucaajinga kutera okuba okw’amangu, kubanga obuziyiza bw’enkola y’eddagala obw’omunda buba wansi nnyo. Wabula nga bwe kisemberera okucaajinga mu bujjuvu, sipiidi y’okucaajinga ekendeera mpolampola olw’obwetaavu bw’okufuga okutuufu okwewala okucaajinga ennyo.

Okubumbako

C-rate yeetaagibwa nnyo okutegeera omutindo gwa bbaatule mu mbeera ez’enjawulo. C-rates eza wansi (okugeza, 0.1c oba 0.2c) zitera okukozesebwa okugezesa okusannyalala/okuggyamu amasannyalaze okw’ekiseera ekiwanvu okwekenneenya obusobozi, obulungi, n’obulamu. C-rates eziri waggulu (okugeza, 1C, 2C, oba okusingawo) zikebera omutindo gwa bbaatule ku byetaago bya chajingi/okufulumya amangu, gamba ng’okusannyalala kw’emmotoka ez’amasannyalaze oba okubuuka ennyonyi ezitali za bulijjo.

Kikulu okumanya nti C-rate esingako bulijjo si nnungi. Wadde nga C-rates ennyingi zisobozesa okucaajinga amangu/okusiibulwa, era zireeta ebiyinza okugwamu ng’okukendeeza ku bulungibwansi, ebbugumu eryeyongedde, n’okuwangaala kwa bbaatule ennyimpi. N’olwekyo, bw’oba ​​olondawo n’okukozesa bbaatule, okutebenkeza C-rate n’ebipimo ebirala eby’omutindo okusinziira ku nkola n’ebyetaago ebitongole kikulu nnyo.
