Indlela yokusombulula ukungalingani kweDynamic Voltage kwiipakethi zebhetri zeLithium

Ukungalingani kwamandla ombane kwiipakethi zebhetri ye-lithium yingxaki enkulu kwii-EV kunye neenkqubo zokugcina amandla, ezihlala zibangela ukutshaja okungaphelelanga, ixesha lokusebenza elifutshane, kunye neengozi zokhuseleko. Ukulungisa le ngxaki ngokufanelekileyo, ukusebenzisa iNkqubo yoLawulo lweBhetri (i-BMS) kunye nokugcinwa okujoliswe kuko kubalulekile.

Ekuqaleni,yenza umsebenzi wokulinganisela we-BMS usebenze. I-BMS ephucukileyo (njengezo zine-active balancing) idlulisela amandla ukusuka kwiiseli ezine-voltage ephezulu ukuya kwezine-voltage ephantsi ngexesha lokutshaja/ukukhupha, nto leyo enciphisa umahluko oguqukayo. Kwi-BMS engasebenziyo, yenza "i-full-charge static balancing" nyanga zonke—vumela ibhetri iphumle iiyure ezi-2-4 emva kokutshaja ngokupheleleyo ukuze i-BMS ilinganise ii-voltage.

Okwesibini, jonga uqhagamshelo kunye nokuhambelana kweeseli. Iibhasi zekopolo ezikhululekileyo okanye iindawo zoqhagamshelwano ezingcolileyo zonyusa ukumelana, zikhulisa ukuhla kwevolthi. Coca uqhagamshelo ngotywala kwaye uqinise amantongomane; tshintsha iindawo ezibolileyo. Kwakhona, sebenzisa iiseli ze-lithium ezifanayo (ezivavanyiweyo malunga nokuphambuka kwangaphakathi kwe-≤5%) ukuze uphephe ukungalingani okukhoyo.

Okokugqibela, phucula iimeko zokukhupha itshaja. Kuphephe ukusebenza kombane ophezulu (umz., ukukhawuleziswa kwe-EV okukhawulezayo) njengoko umbane ophezulu usenza i-voltage yehle kakhulu. Sebenzisa iitshaja ezilawulwa yi-BMS ezilandela ingqiqo ethi "pre-charge → constant current → constant voltage", nto leyo enciphisa ukuqokelelana kokungalingani.

Ngokudibanisa ukusebenza kwe-BMS kunye nokugcinwa ngononophelo, unokusombulula ukungalingani kwamandla ombane kwaye wandise ubomi bebhetri ye-lithium.
