Iintlobo zezixhobo zokuvavanya ibhetri ye-lithium
Kukho iintlobo ezininzi zezixhobo zokuvavanya ibhetri ye-lithium ngokweemfuno ezahlukeneyo zovavanyo kunye neendlela zovavanyo. Zinokwahlulwahlulwa zibe zezi ndidi zilandelayo:
1. Umvavanyi womthamo webhetri
Umthamo webhetri luphawu olubalulekileyo lokulinganisa umthamo wokugcina amandla weebhetri ze-lithium.Abavavanyi bomthamo webhetrizidla ngokusetyenziswa ukuvavanya amandla okwenyani eebhetri ze-lithium. Inkqubo yovavanyo ibandakanya ukujonga inkqubo yokutshaja nokukhupha ibhetri kunye nokurekhoda inani elipheleleyo lombane onokukhutshwa xa ibhetri ikhutshwa kwi-voltage yokuphelisa (kwi-Ah okanye kwi-mAh). Olu hlobo lwesixhobo lunokumisela umahluko phakathi kwamandla okwenyani kunye namandla aqhelekileyo ebhetri ngokukhupha umbane rhoqo.
2. Inkqubo yovavanyo lokutshaja ibhetri kunye nokukhupha ibhetri
Inkqubo yovavanyo lokutshaja nokukhupha ibhetri sisixhobo esinamandla sovavanyo esinokulinganisa iimeko zokutshaja nokukhupha ibhetri ngexesha lokusetyenziswa kwayo. Le nkqubo yovavanyo idla ngokusetyenziselwa ukubona ukusebenza kakuhle, ubomi bomjikelo, ukutshaja kunye nokusebenza kokukhupha ibhetri. Ivavanya ukusebenza kwebhetri phantsi kweemeko ezahlukeneyo zokusebenza ngokulawula ngokuchanekileyo iiparameter ezifana nokutshaja kunye nokukhutshelwa kwamandla, i-voltage yetshaja, i-voltage yokukhupha kunye nexesha.
3. Umvavanyi wokumelana kwangaphakathi kwebhetri
Ukumelana kwangaphakathi kwebhetri yenye yezinto ezibalulekileyo ezichaphazela ukusebenza kweebhetri ze-lithium. Ukumelana kwangaphakathi okugqithisileyo kunokubangela ubushushu obugqithisileyo bebhetri, ukunciphisa umthamo wayo kunye neengxaki zokhuseleko.umvavanyi wokuxhathisa kwangaphakathi kwebhetriibala ukumelana kwangaphakathi kwebhetri ngokulinganisa utshintsho lwevolthi yebhetri phantsi kweemeko ezahlukeneyo zokutshaja kunye nokukhupha. Oku kubaluleke kakhulu ekuvavanyeni impilo yebhetri kunye nokuqikelela ubomi bebhetri.
4. Isilinganisi sebhetri
Isixhobo sokulinganisa ibhetri sisixhobo sokuvavanya esinokulinganisa utshintsho kwiimpawu ze-voltage kunye nezangoku zeebhetri ze-lithium. Sisetyenziswa rhoqo ekuphuhlisweni nasekuvavanyweni kweenkqubo zolawulo lwebhetri (i-BMS). Silinganisa indlela esebenza ngayo ibhetri xa isetyenziswa ngokudibanisa umthwalo we-elektroniki kunye nombane, sinceda abasebenzi be-R&D ukuba bavavanye impendulo yenkqubo yolawulo lwebhetri kwiimeko ezahlukeneyo zokutshaja kunye nokukhupha.
5. Inkqubo yovavanyo lokusingqongileyo
Ukusebenza kweebhetri ze-lithium kuya kutshintsha phantsi kweemeko ezahlukeneyo zokusingqongileyo ezifana nobushushu kunye nokufuma.
