1. Intshayelelo yebhetri ye-lithium-ion
1.1 iState of Charge (SOC)
Imeko yentlawulo inokuchazwa njengemeko yamandla ombane akhoyo ebhetrini, adla ngokuchazwa njengepesenti.Ngenxa yokuba amandla ombane akhoyo ahluka ngokutshaja kunye nokukhupha ngoku, ubushushu kunye nesiganeko sokuguga, inkcazo yesimo somrhumo iphinda ihlulwe ibe yintlobo ezimbini: i-Absolute State-Of-Charge (ASOC) kunye ne-Relative State-Of-Charge (RSOC) .
Ngokuqhelekileyo, uluhlu lwemeko yokuhlawula i-0% - 100%, ngelixa i-100% xa ibhetri igcwele ngokupheleleyo kunye ne-0% xa ikhutshwe ngokupheleleyo.Imo yentlawulo epheleleyo lixabiso lereferensi elibalwe ngokwexabiso lesakhono esimisiweyo esiyilelweyo xa ibhetri yenziwe.Imeko yokuhlawula ngokupheleleyo ibhetri entsha egcwaliswe ngokupheleleyo yi-100%;Nangona ibhetri yokuguga ihlawuliswe ngokupheleleyo, ayikwazi ukufikelela kwi-100% phantsi kweemeko ezahlukeneyo zokutshaja kunye nokukhupha.
Lo mzobo ulandelayo ubonisa ubudlelwane phakathi kwamandla ombane kunye nomthamo webhetri kumazinga ahlukeneyo okukhutshwa.Okukhona isantya sokukhupha siphezulu, kokukhona sisezantsi umthamo webhetri.Xa ubushushu buphantsi, umthamo webhetri nawo uya kuncipha.

1.2 IVoltage yokuTshaja enkulu
Ubuninzi bombane wokutshaja bunxulumene nokwakheka kweekhemikhali kunye neempawu zebhetri.I-voltage yokutshaja ibhetri ye-lithium idla ngokuba yi-4.2V kunye ne-4.35V, kwaye amaxabiso ombane we-cathode kunye nezinto ze-anode ziya kuhluka.
1.3 Ihlawuliswa ngokupheleleyo
Xa umahluko phakathi kwamandla ombane webhetri kunye nowona mbane uphezulu wokutshaja ungaphantsi kwe-100mV kwaye umsinga wokutshaja uncitshiswe ukuya kutsho kwi-C/10, ibhetri inokubonwa njengetshajiswe ngokupheleleyo.Iimeko zokutshaja ngokupheleleyo ziyahluka ngokweempawu zebhetri.
Lo mzobo ungezantsi ubonisa ijiko eliqhelekileyo lokutshaja ibhetri ye-lithium.Xa amandla ombane ebhetri elingana nowona mbane uphezulu wokutshaja kwaye umsinga wokutshaja uncitshiswe ukuya kutsho kwi-C/10, ibhetri ithathwa njengetyala ngokupheleleyo.

1.4 Ubuncinci bombane wokukhupha
Ubuncinci bokukhupha i-voltage inokuchazwa ngumbane wokuqhawula, oqhelekileyo umbane xa imeko yentlawulo i-0%.Eli xabiso lombane alikho ixabiso elimiselweyo, kodwa litshintsha ngomthwalo, ubushushu, iqondo lokuguga okanye ezinye izinto.
1.5 Ukukhutshwa ngokupheleleyo
Xa umbane webhetri ungaphantsi okanye ulingana nowona mthamo uncinci wokukhupha, unokubizwa ngokuba ngukukhutshwa okupheleleyo.
1.6 Intlawulo kunye nexabiso lokukhupha (i-C-Rate)
Ixabiso lokukhupha intlawulo yimbonakaliso yentlawulo-ukukhutshwa ngoku ngokumalunga nomthamo webhetri.Ngokomzekelo, ukuba usebenzisa i-1C ukukhupha iyure enye, ngokufanelekileyo, ibhetri iya kukhupha ngokupheleleyo.Iintlawulo ezahlukeneyo zokukhupha intlawulo ziya kubangela umthamo osebenzayo ohlukeneyo.Ngokubanzi, okukhona isantya sokukhupha intlawulo siphezulu, kokukhona sincinci umthamo okhoyo.
1.7 Ubomi bomjikelo
Inani lemijikelezo libhekisela kwinani lentlawulo epheleleyo kunye nokukhutshwa kwebhetri, enokuthi iqikelelwe ngumthamo wangempela wokukhupha kunye nomthamo woyilo.Xa umthamo wokukhupha oqokelelweyo ulingana nomthamo woyilo, inani lemijikelezo liya kuba linye.Ngokuqhelekileyo, emva kwemijikelezo ye-500 yokukhupha imali, umthamo webhetri egcwele ngokupheleleyo uya kuncipha nge-10% ~ 20%.

1.8 Ukuzikhupha
Ukuzikhupha kuzo zonke iibhetri kuya kwanda ngokunyuka kweqondo lokushisa.Ukuzikhupha ngokusisiseko akuyiyo impazamo yokuvelisa, kodwa iimpawu zebhetri ngokwayo.Nangona kunjalo, unyango olungafanelekanga kwinkqubo yokuvelisa luya kubangela ukwanda kokuzikhupha.Ngokuqhelekileyo, izinga lokuzikhupha liza kuphinda liphindwe kabini xa ubushushu bebhetri bukhuphuka nge-10 ° C. Umthamo wokuzikhupha webhetri ye-lithium-ion malunga ne-1-2% ngenyanga, ngelixa i-nickel-based battery i-10- I-15% ngenyanga.
