Ibhetri yeLithiumkuthiwa ayintsonkothanga, enyanisweni, ayintsonkothanga kakhulu, ithe ilula, enyanisweni, ayilula.Ukuba ubandakanyeka kule shishini, ngoko ke kuyimfuneko ukuqonda amanye amagama aqhelekileyo asetyenziswa kwi-lithium ibhetri ye-lithium, ngoko ke, yintoni na amagama aqhelekileyo asetyenziswa kwi-lithium battery industry?
Amagama aqhelekileyo asetyenziswa kwishishini lebhetri ye-lithium
1.Ixabiso leNtlawulo/Ixabiso lokukhupha
Ibonisa ukuba ingakanani yangoku yokuhlawula kunye nokukhupha, ngokubanzi kubalwa njengento ephindaphindiweyo yomthamo wesigxina webhetri, ngokuqhelekileyo ebizwa ngokuba yimbalwa C. Njengebhetri enomthamo we-1500mAh, kuchazwe ukuba i-1C = 1500mAh, ukuba ikhutshwe I-2C iphinda ikhutshwe ngokukhoyo kwe-3000mA, i-0.1C intlawulo kunye nokukhutshwa kuhlawuliswa kwaye kukhutshwe nge-150mA.
2.OCV: Vula iVoltage yeSekethe
Umbane webhetri ngokubanzi ubhekisa kumbane oqhelekileyo (okwabizwa ngokuba yivoltheji elinganisiweyo) yebhetri ye-lithium.Umbane oqhelekileyo webhetri ye-lithium eqhelekileyo ngokuqhelekileyo yi-3.7V, kwaye sibiza iqonga layo lombane li-3.7V.Ngombane sibhekisa ngokubanzi kumbane ovulekileyo wesekethe yebhetri.
Xa ibhetri i-20 ~ 80% yomthamo, i-voltage igxininiswe malunga ne-3.7V (malunga ne-3.6 ~ 3.9V), umthamo ophezulu kakhulu okanye ophantsi kakhulu, i-voltage ihluka ngokubanzi.
3.Amandla/Amandla
Amandla (E) enokuthi ibhetri iwakhuphe xa ikhutshwa kumgangatho othile, ngeWh (watt iiyure) okanye KWh (iiyure zekilowatt), ukongeza i-1 KWh = 1 kWh yombane.
Ingqikelelo esisiseko ifumaneka kwiincwadi zefiziksi, E=U*I*t, ekwalingana nombane webhetri ophindaphindwe ngamandla ebhetri.
Kwaye ifomula yamandla ithi, P=U*I=E/t, ebonisa ubungakanani bamandla anokukhutshwa kwiyunithi nganye yexesha.Iyunithi yiW (watt) okanye KW (kilowatt).
Ibhetri enomthamo we-1500 mAh, umzekelo, inomthamo oqhelekileyo we-3.7V, ngoko ke amandla ahambelanayo yi-5.55Wh.
4.Ukuchasa
Njengoko ukuhlawuliswa kunye nokukhutshwa akunakulinganiswa nokunikezelwa kwamandla afanelekileyo, kukho ukuchasana okuthile kwangaphakathi.Ukuchasana kwangaphakathi kudla amandla kwaye ngokuqinisekileyo okuncinci ukuchasana kwangaphakathi kungcono.
Ukuxhathisa kwangaphakathi kwebhetri kulinganiswa ngeemiliohms (mΩ).
Ukuchasana kwangaphakathi kwebhetri jikelele kuqulethe ukuchasana kwe-ohmic yangaphakathi kunye ne-polarized ukumelana kwangaphakathi.Ubungakanani bokuchasana kwangaphakathi buphenjelelwa zizinto zebhetri, inkqubo yokuvelisa, kunye nesakhiwo sebhetri.
5.Cycle Life
Ukutshaja ibhetri kunye nokukhupha kanye kubizwa ngokuba ngumjikelo, ubomi bomjikelezo sisalathisi esibalulekileyo sokusebenza kwebhetri.Umgangatho we-IEC uchaza ukuba kwiibhetri ze-lithium zefowuni, i-0.2C ikhupha kwi-3.0V kunye ne-1C intlawulo ukuya kwi-4.2 V. Emva kwemijikelezo ephindaphindiweyo ye-500, amandla ebhetri kufuneka ahlale ngaphezu kwe-60% yomthamo wokuqala.Ngamanye amazwi, ubomi bomjikelezo webhetri ye-lithium ngamaxesha angama-500.
Umgangatho kazwelonke umisela ukuba emva kwemijikelo engama-300, umthamo kufuneka uhlale kwi-70% yomthamo wokuqala.Iibhetri ezinomthamo ongaphantsi kwama-60% omthamo wokuqala kufuneka ziqwalaselwe ngokubanzi ukulahlwa kwezinto ezilahliweyo.
6.DOD: Ubunzulu bokukhutshwa
Ichazwa njengepesenti yomthamo okhutshiweyo kwibhetri njengepesenti yomthamo olinganisiweyo.Ubunzulu bokukhutshwa kwebhetri ye-lithium ngokubanzi, bufutshane ubomi bebhetri.
7.Sika iVoltage
Amandla ombane okuphelisa ahlulahlulwe abe ngamandla ombane wokutshaja okuphelisa kunye nowokuphela amandla ombane, nto leyo ethetha amandla ombane apho ibhetri ingenako ukutshajwa okanye ukukhutshwa ngokubhekele phaya.Ukutshaja ukupheliswa kombane webhetri ye-lithium ngokuqhelekileyo yi-4.2V kunye ne-voltage yokuphelisa ukukhupha yi-3.0V.Ukutshaja okunzulu okanye ukukhupha ibhetri ye-lithium ngaphaya kombane wokuphelisa akuvumelekanga ngokungqongqo.
8.Ukuzikhupha
Ibhekiselele kumlinganiselo wokuhla kumthamo webhetri ngexesha logcino, ichazwa njengepesenti yokuncipha komxholo kwiyunithi nganye yexesha.Izinga lokuzikhupha kwibhetri ye-lithium eqhelekileyo yi-2% ukuya kwi-9% / ngenyanga.
9.SOC(iState of charge)
Ibhekisa kwipesenti yentlawulo eseleyo yebhetri kwintlawulo iyonke enokukhutshwa, i-0 ukuya kwi-100%.Ibonakalisa intlawulo eseleyo yebhetri.
10.Umthamo
Ibhekisa kubungakanani bamandla obunokufunyanwa kwibhetri ye-lithium phantsi kweemeko ezithile zokukhupha.
Ifomyula yombane yi-Q=I*t kwii-coulombs kwaye iyunithi yomthamo webhetri ichazwe njenge-Ah (iiyure ze-ampere) okanye mAh (iiyure ze-milliampere).Kuthetha ukuba ibhetri ye-1AH inokukhutshwa ngeyure ye-1 kunye ne-current ye-1A xa ihlanjwe ngokupheleleyo.
