Ziziphi iireyithi zokukhupha iibhetri ze-lithium?

Kubahlobo abangenzi iibhetri ze-lithium, abazi ukuba yintoni isantya sokukhutshwa kweebhetri ze-lithium okanye yintoni inombolo ye-C yeebhetri ze-lithium, makungabikho ukuba yintoni imilinganiselo yokukhutshwa kweebhetri ze-lithium.Masifunde malunga nezinga lokukhutshwa kweebhetri ze-lithium ngebhetri ye-R&D yeenjineli zobugcisaIbhetri yesixhobo seUrun.

Masifunde malunga nenombolo ye-C yokukhutshwa kwebhetri ye-lithium.C imele isimboli sezinga lokukhutshwa kwebhetri ye-lithium.Ngokomzekelo, i-1C imele i-lithium ibhetri yokukwazi ukukhupha ngokuzinzileyo ngamaxesha e-1 izinga lokukhupha, njalo njalo.Ezinye ezifana ne-2C, 10C, 40C, njl., zimele ubuninzi bangoku ukuba ibhetri ye-lithium inokukhupha ngokuzinzileyo.amaxesha okukhupha.

Umthamo webhetri nganye sisixa esithile kwixesha elithile, kwaye izinga lokukhutshwa kwebhetri libhekiselele kumlinganiselo wokukhupha amaxesha amaninzi okukhutshwa okuqhelekileyo kwithuba lexesha elifanayo xa kuthelekiswa nokukhutshwa okuqhelekileyo.Amandla anokukhutshwa phantsi kwee-currents ezahlukeneyo, ngokuqhelekileyo ukuthetha, iiseli kufuneka zivavanye ukusebenza kokukhutshwa phantsi kweemeko ezahlukeneyo zangoku.Indlela yokuvavanya ireyithi yebhetri (inombolo C - ingakanani ireyithi)?

Xa ibhetri ikhutshwe ngokuphindaphindiweyo kwe-N i-1C umthamo webhetri, kwaye umthamo wokukhupha ungaphezulu kwe-85% ye-capacity ye-1C yebhetri, sicinga ukuba izinga lokukhutshwa kwebhetri liyi-N rate.

Umzekelo: ibhetri ye-2000mAh, xa ikhutshwe ngebhetri ye-2000mA, ixesha lokukhutshwa liyi-60min, ukuba likhutshwe nge-60000mA, ixesha lokukhutshwa ngu-1.7min, sicinga ukuba izinga lokukhutshwa kwebhetri ngamaxesha angama-30 (30C).

Umbane ophakathi (V) = umthamo wokukhupha (Wh) ÷ umsinga wokukhupha (A)

I-voltage ye-Median (V): Inokuqondwa njengexabiso le-voltage ehambelana ne-1/2 yexesha elipheleleyo lokukhutshwa.

Umbane ophakathi nawo unokubizwa ngokuba yi-discharge plateau.I-plateau yokukhupha ihambelana nezinga lokukhutshwa (ngoku) kwebhetri.Okukhona uphezulu umyinge wokukhutshelwa, kokukhona usezantsi amandla ombane eplateau yokukhupha, enokumiselwa ngokubala amandla okukhutshwa kwebhetri (Wh)/umthamo wokukhupha (Ah).iqonga layo lokukhupha.

Iibhetri ze-18650 eziqhelekileyo ziquka i-3C, i-5C, i-10C, njl.izixhobo zamandla, iipakethi zebhetri yemoto yombane, kunye neesaha zentsimbi.
