Ngaba ukhe waqaphela ukuba ibhetri ye-lithium ibhetri yehla kanye emva kokuba ihlawuliswe ngokupheleleyo? Oku ayisosiphene—yihambo eqhelekileyo yomzimba eyaziwa ngokubaukuhla kwamandla ombane. Masithathe i-8-cell LiFePO₄ yethu (i-lithium iron phosphate) i-24V yesampulu yebhetri yelori njengomzekelo wokucacisa.
1. Yintoni i-Voltge Drop?
Ngokwethiyori, le bhetri kufuneka ifikelele kwi-29.2V xa ihlanjwe ngokupheleleyo (3.65V × 8). Nangona kunjalo, emva kokususa umthombo wamandla wangaphandle, umbane wehla ngokukhawuleza ukuya malunga ne-27.2V (malunga ne-3.4V ngeseli nganye). Nasi isizathu:
- Amandla ombane aphezulu ngexesha lokutshaja kuthiwa yiUkutshaja i-Cutoff Voltage;
- Nje ukuba ukutshaja kuyekile, i-polarization yangaphakathi iyanyamalala, kwaye i-voltage yehla ngokwendaloVula iVoltage yeSekethe;
- Iiseli zeLiFePO₄ zihlala zihlawulisa ukuya kuthi ga kwi-3.5-3.6V, kodwa zonaayikwazi ukugcina eli nqanabaixesha elide. Endaweni yoko, bazinza kwi-voltage yeqonga phakathiI-3.2V kunye ne-3.4V.
Kungenxa yoko le nto i-voltage ibonakala "ihla" kanye emva kokutshaja.
2. Ngaba ukuhla kweVoloji kuyasichaphazela isakhono?
Abanye abasebenzisi banexhala lokuba oku kwehla kwamandla ombane kunokunciphisa umthamo webhetri osebenzisekayo. Inyaniso:
- Iibhetri ze-lithium ezihlakaniphile zineenkqubo zokulawula ezakhelwe ngaphakathi ezilinganisa ngokuchanekileyo kunye nokulungelelanisa umthamo;
- Iiapps ezenziwe ngeBluetooth zivumela abasebenzisi ukuba babeke ilisoamandla okwenene agciniweyo(okt, amandla okukhutshwa asebenzisekayo), kunye nohlengahlengiso lwe-SOC (iState of Charging) emva kwentlawulo epheleleyo;
- Ngoko ke,Ukuhla kwamandla ombane akukhokheli ekunciphiseni umthamo osebenzisekayo.
3. Kufuneka Ulumke nini malunga nokuLahlwa kweVoltage
Ngelixa ukwehla kwamandla ombane kuqhelekile, kunokugqithiswa phantsi kweemeko ezithile:
- Impembelelo yobushushu: Ukutshaja kubushushu obuphezulu okanye obuphantsi kunokubangela ukwehla kwamandla ombane ngokukhawuleza;
- Ukuguga kweeSeli: Ukonyuka kokuchasana kwangaphakathi okanye amazinga aphezulu okuzikhupha nawo anokubangela ukuhla kwamandla ombane ngokukhawuleza;
- Ke abasebenzisi kufuneka balandele iindlela zokusetyenziswa ezifanelekileyo kwaye babeke iliso kwimpilo yebhetri rhoqo.
Ukuqukumbela
Ukuhla kwe-voltage yinto eqhelekileyo kwiibhetri ze-lithium, ngakumbi kwiintlobo ze-LiFePO₄. Ngolawulo oluphezulu lwebhetri kunye nezixhobo zokubeka iliso ezihlakaniphile, sinokuqinisekisa ukuchaneka kokufunda umthamo kunye nempilo yexesha elide kunye nokhuseleko lwebhetri.
