C-rate ya betri i yuniti leyi pimaka rivilo ra ku chaja kumbe ku humesa betri, leyi tlhelaka yi tiviwa tani hi charge/discharge rate. Hi ku kongoma, C-rate yi yimela vuxaka byo tala exikarhi ka current ya charge/discharge ya betri na vuswikoti bya yona lebyi ringanyetiweke. Fomula ya xibalo hi leyi:
Nhlayo ya ku Chaja/Ku Humesa = Nhlayo ya ku Chaja/Ku Humesa ya sweswi / Vuswikoti lebyi ringanyetiweke
Nhlamuselo: C-rate, leyi tlhelaka yi vuriwa charge/discharge rate, i ratio ya charge/discharge current eka vuswikoti bya vito bya betri. Xikombiso, eka betri leyi nga na vuswikoti lebyi ringanyetiweke bya 100Ah, ku humesa hi current ya 20A swi fambelana na discharge rate ya 0.2C.
Ku twisisa: C-rate ya discharge, yofana na 1C, 2C, kumbe 0.2C, yikomba rivilo ra discharge. Mpimo wa 1C wuvula leswaku betri yinga humesa hiku hetiseka eka awara yin’we, kasi 0.2C yikomba ku humesa eka tiawara ta ntlhanu. Hi ntolovelo, ti current to hambana hambana ta discharge tinga tirhisiwa ku pima vuswikoti bya betri. Eka betri ya 24Ah, 2C discharge current i 48A, kasi 0.5C discharge current i 12A.
Ku Kamberiwa ka Matirhelo: Hi ku humesa hi ti C-rates to hambana, swa koteka ku kambela ti parameter ta betri to fana na vuswikoti, ku lwisana ka le ndzeni, na pulatifomo yo humesa, leswi pfunetaka ku kambela khwalithi ya betri na vutomi bya yona.
Swiendlakalo swa Xikombelo: Swiendlakalo swo hambana swa xikombelo swi na swilaveko swo hambana swa C-rate. Xikombiso, mimovha ya gezi yi lava tibetiri ta C-rate ya le henhla ku hatlisa ku chaja/ku humesa, kasi tisisiteme to hlayisa eneji ti rhangisa vutomi byo leha na ntsengo, hakanyingi ti hlawula ku chaja na ku humesa C-rate ya le hansi.
Matirhelo ya Tisele
Cell Capacity: C-rate kahle kahle i ratio ya charge/discharge current eka cell’s rated capacity. Xisweswo, vuswikoti bya sele byi boha hi ku kongoma mpimo wa C. Loko vuswikoti bya ti cell byi ri byikulu, C-rate yale hansi eka discharge current leyi fanaka, naswona vice versa.
Switirhisiwa na Xivumbeko xa Sele: Switirhisiwa na xivumbeko xa sele, ku katsa na switirhisiwa swa electrode, na muxaka wa electrolyte, swi khumba matirhelo ya charge/discharge xisweswo swi khumba C-rate. Switirhisiwa swin’wana swinga seketela ku chaja na ku humesa hi ntsengo wale henhla, kasi swin’wana swinga lulamela swinene eka switirhisiwa swa ntsengo wale hansi.
Dizayini ya Xipaci xa Betiri
Vulawuri bya ku Hisisa: Hi nkarhi wa ku chaja/ku humesa, betri yi humesa ku hisa lokukulu. Loko vulawuri bya thermal byinga enelangi, mahiselo yale ndzeni yata tlakuka, leswinga hunguta matimba ya charge xikan’we naku khumba C-rate. Hikwalaho, pulani ya kahle ya ku hisa i ya nkoka swinene eka ku ndlandlamuxa C-rate ya betri.
Battery Monitoring System (BMS) : BMS yi languta no lawula betri, ku katsa na ku lawula charge/discharge, temperature, etc. Hi ku lawula kahle charge/discharge current na voltage, BMS yi antswisa matirhelo ya betri, hi ndlela yaleyo yi antswisa C-rate.
Swiyimo swa le Handle
Mahiselo ya Ndhawu: Mahiselo ya mbango i nchumu wa nkoka eka matirhelo ya betri. Eka mahiselo yale hansi, rivilo ro chaja rihunguteka, naswona vuswikoti byo humesa byi siveriwa, leswi hungutaka C-rate. Hi ndlela yohambana, eka mahiselo yale henhla, ku hisa ngopfu swinga tlhela swi khumba C-rate.
Xiyimo xa Betiri (SOC): Loko SOC ya betri yi ri ehansi, ku chaja ku tala ku hatlisa, tanihi leswi ku lwisana ka le ndzeni ka tikhemikhali ku nga ehansi swinene. Kambe loko yi tshinela eka full charge, rivilo ro chaja rihunguteka hakatsongotsongo hikokwalaho ka xilaveko xa vulawuri lebyi kongomeke ku papalata ku chaja ngopfu.
C-rate i ya nkoka eka ku twisisa matirhelo ya betri ehansi ka swiyimo swo hambana. Ti C-rates tale hansi (xikombiso, 0.1C kumbe 0.2C) titala kutirhisiwa eka swikambelo swa nkarhi woleha swa charge/discharge ku kambela vuswikoti, vukorhokeri, na vutomi. Ti-C-rate ta le henhla (xikombiso, 1C, 2C, kumbe ku tlula) ti kambela matirhelo ya betri eka swilaveko swa ku hatlisa/ku humesa, ku fana na ku hatlisisa ka movha wa gezi kumbe ku haha ka drone.
I swa nkoka ku xiya leswaku C-rate yale henhla ahi minkarhi hinkwayo yi antswa. Loko ti C-rates tale henhla ti endla leswaku ku hatlisa ku chaja/ku humesa, titlhela ti tisa swiphiqo leswinga vaka kona swofana na kuhunguteka ka vukorhokeri, ku tlakuka ka kuhisa, na vutomi byo koma bya betri. Hikokwalaho, loko u hlawula naku tirhisa tibetiri, ku ringanisela C-rate na ti parameter tin’wana ta matirhelo kuya hi xitirhisiwa xokarhi na swilaveko i swa nkoka swinene.
