3. Intlawulo / ukukhupha umphindaphindi (intlawulo / ireyithi yokukhupha, iyunithi: C)
Intlawulo/ukukhupha isiphindaphindi:umlinganiselo wokuba intlawulo ikhawuleza kangakanani okanye icotha kangakanani na. Esi salathisi sichaphazela imisinga eqhubekayo kunye nencopho yebhetri ye-lithium-ion xa isebenza, kwaye iyunithi yayo ngokuqhelekileyo i-C (isifinyezo se-C-rate), njenge-1 / 10C, 1 / 5C, 1C, 5C, 10C, njl. .. Umzekelo, ukuba umthamo olinganisiweyo webhetri yi-20Ah, kwaye ukuba intlawulo yayo elinganisiweyo / i-discharge multiplier yi-0.5C, oko kuthetha ukuba le bhetri, inokuhlawuliswa kwaye ikhutshwe ngokuphindaphindiweyo kunye ne-current ye-20Ah * 0.5C = 10A, ukuya kwi-voltage enqunyiwe yokutshaja okanye ukukhupha. Ukuba ubuninzi bayo bokukhupha i-multiplier ngu-10C@10s kwaye isiphindaphindi saso esiphezulu sentlawulo yi-5C@10s, ngoko ke le bhetri inokukhutshwa kunye ne-current ye-200A ixesha le-10 imizuzwana kwaye ihlawulwe ngokusebenza kwe-100A ixesha le-10 imizuzwana.
Okukhona inkcazo yenkcazo yokutshaja kunye nokukhupha i-multiplier index, ibaluleke kakhulu isikhokelo sokusetyenziswa. Ngokukodwa kwiibhetri ze-lithium-ion, ezisetyenziswa njengomthombo wamandla wezithuthi zokuthutha umbane, izalathi zokuphindaphinda eziqhubekayo kunye ne-pulse phantsi kweemeko ezahlukeneyo zokushisa kufuneka zichazwe ukuze kuqinisekiswe ukuba iibhetri ze-lithium-ion zisetyenziswa ngaphakathi koluhlu olufanelekileyo.
4. Umbane (iyunithi: V)
I-voltage yebhetri ye-lithium-ion ineeparameters ezifana ne-voltage yesiphaluka evulekileyo, i-voltage yokusebenza, ukutshaja i-voltage ye-cut-off, ukukhupha i-voltage yokusika kunye nokunye.
Umbane ovulelekileyo:oko kukuthi, ibhetri ayixhunyiwe kuwo nawuphi na umthwalo wangaphandle okanye unikezelo lwamandla, linganisa umahluko onokubakho phakathi kweeterminal ezintle kunye nezibi zebhetri, lo ngumbane ovulekileyo wesiphaluka sebhetri.
Umbane osebenzayo:ngumthwalo wangaphandle webhetri okanye unikezelo lwamandla, kwimeko yokusebenza, kukho ukuhamba kwangoku, kulinganiswa ngumahluko onokuthi ubekho phakathi kwee-electrode ezilungileyo kunye nezibi. I-voltage yokusebenza ihambelana nokubunjwa kwesekethe kunye nemeko yokusebenza yezixhobo, lixabiso lokutshintsha. Ngokuqhelekileyo, ngenxa yobukho bokuchasana kwangaphakathi kwebhetri, umbane osebenzayo ungaphantsi kombane ovulekileyo wesekhethi kwimeko ekhutshiweyo, kwaye uphezulu kunombane ovulekileyo wesiphaluka kwisimo sokutshaja.
Ukutshaja / ukukhupha amandla ombane aphelileyo:Ngowona mbane uphezulu kunye nobuncinci bokusebenza ibhetri evumelekileyo ukuba ifikelele kuyo. Ukugqitha kulo mda kuya kubangela umonakalo ongenakulungiseka kwibhetri, okukhokelela ekuthotyweni kokusebenza kwebhetri, kwaye kwiimeko ezinzima, kude kubangele umlilo, ukuqhuma kunye nezinye iingozi zokhuseleko.
