Xana C-rate ya betri i yini?

C-rate ya betri i yuniti leyi pimaka rivilo ra ku chaja ka betri kumbe ku humesa, leyi tlhelaka yi tiviwa tanihi mpimo wa ku chaja/ku humesa. 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 i:

Nhlayo ya ku hakela/ku humesa = current ya ku hakela/ku humesa / vuswikoti lebyi ringanyetiweke .

Nhlamuselo na ku twisisa ka C-rate .

• Nhlamuselo: C-rate, leyi tlhelaka yi vuriwa charge/discharge rate, i ratio ya charge/discharge current eka capacity ya vito ra battery. Xikombiso, eka betri leyi nga na vuswikoti lebyi ringanyetiweke bya 100AH, ku humesa eka current ya 20A swi fambelana na mpimo wa ku humesiwa ka 0.2C.

• Ku twisisa: C-rate ya discharge, ku fana na 1C, 2C, kumbe 0.2C, yi kombisa rivilo ra ku humesa. Mpimo wa 1C swivula leswaku betri yinga humesa hiku hetiseka hi awara yin’we, kasi 0.2C yikomba ku humesiwa eka tiawara ta ntlhanu. Hiku angarhela, ti discharge currents tohambana hambana tinga tirhisiwa ku pima vuswikoti bya betri. Eka betri ya 24AH, current ya 2C discharge i 48A, kasi 0.5C discharge current i 12A.

Switirhisiwa swa C-Rate .

• Ku kamberiwa ka matirhelo: Hi ku humesa eka ti-C-rate to hambana, swa koteka ku kambela tipharamitha ta betri ku fana na vuswikoti, ku lwisana ka le ndzeni, na pulatifomo yo humesa, leswi pfunetaka ku kambela khwalithi ya betri na vutomi.

• Swiendlakalo swa matirhiselo: Swiendlakalo swo hambana swa matirhiselo swi na swilaveko swo hambana swa C-rate. Xikombiso, mimovha ya gezi yi lava tibetiri ta le henhla ta C-rate eka ku chaja hi ku hatlisa/ku humesiwa, kasi tisisiteme ta vuhlayiselo bya eneji ti rhangisa vutomi byo leha na ntsengo, hakanyingi ti hlawula ku chaja na ku humesa mpimo wa le hansi wa C-rate.

Swilo leswi khumbaka C-rate .

Ku tirha ka tisele .

• Vuswikoti bya sele: C-rate hi xiviri i ratio ya charge/discharge current eka vuswikoti lebyi ringanyetiweke bya sele. Xisweswo, vuswikoti bya sele hi ku kongoma byi boha C-rate. Loko vuswikoti bya sele byi ri byikulu, C-rate ya le hansi ya current yo fana ya discharge, na vice versa.

• Switirhisiwa swa sele na xivumbeko: Switirhisiwa na xivumbeko xa sele, ku katsa na switirhisiwa swa electrode, na muxaka wa electrolyte, ku khumba matirhelo ya charge/discharge xisweswo swi khumba C-rate. Switirhisiwa swin’wana swi nga ha seketela ku chaja ni ku humesa swilo swa xiyimo xa le henhla, kasi swin’wana swi nga ha faneleka swinene eka switirhisiwa swa xiyimo xa le hansi.

Dizayini ya Battery Pack .

• Vulawuri bya mahiselo: Hi nkarhi wa charge/discharge, battery pack yi humesa kuhisa lokukulu. Loko vulawuri bya mahiselo byi nga enelangi, mahiselo ya le ndzeni ya ta tlakuka, ya hunguta matimba ya charge na ku khumba C-rate. Hikokwalaho, dizayini ya kahle ya mahiselo i ya nkoka swinene eka ku ndlandlamuxa C-rate ya betri.

• Sisiteme yo Langutisisa Betiri (BMS) : BMS yi languta no lawula betri, ku katsa na ku lawula ku chaja/ku humesa, ku hisa, na swin’wana na swin’wana Hi ku lawula kahle current ya charge/discharge na voltage, BMS yi antswisa matirhelo ya betri, hi ndlela yoleyo yi antswisa C-rate.

Swiyimo swa le handle .

• Mahiselo ya ndzhawu: Ku hisa ka mbango i nchumu lowukulu eka matirhelo ya betri. Eka mahiselo yale hansi, rivilo ro chaja ri hunguta rivilo, naswona vuswikoti byo humesa bya siveriwa, leswi hungutaka C-rate. Hi ndlela yohambana, eka mahiselo yale henhla, ku hisa ngopfu swinga tlhela swi khumba C-rate.

• Xiyimo xa Battery xa charge (SOC): Loko SOC ya betri yi ri ehansi, ku chaja ku tala ku hatlisa, tanihileswi ku lwisana ka le ndzeni ka tikhemikhali ku nga ehansi swinene. Kambe loko yi tshinela eka charge leyi heleleke, rivilo ra ku chaja ri hunguteka hakatsongo-tsongo hikwalaho ka xilaveko xa vulawuri lebyi kongomeke leswaku ku papalatiwa ku chaja ku tlula mpimo.

Nkomiso

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 ku kuma swilaveko swa ku chaja hi ku hatlisa/ku humesa, ku fana na ku hatlisisa movha wa gezi kumbe ku haha ​​ka drone.

I swa nkoka ku xiya leswaku C-rate ya le henhla a hi minkarhi hinkwayo yi antswaka. Loko ti C-rates tale henhla ti endla leswaku kuva na charge/discharge hiku hatlisa, titlhela ti tisa swiphiqo leswinga vaka kona swofana na kuhunguteka ka vukorhokeri, ku hisa loku engetelekeke, na vutomi byo koma bya betri. Hikwalaho, loko u hlawula na ku tirhisa tibetiri, ku ringanisela C-rate na tipharamitha tin’wana ta matirhelo ku ya hi xitirhisiwa xo karhi na swilaveko i swa nkoka swinene.
