Maitiro Ekugadzirisa Dynamic Voltage Imbalance muLithium Battery Packs

Kusawirirana kwemagetsi mumabhatiri e lithium idambudziko guru kumaEV nemasisitimu ekuchengetera magetsi, zvichikonzera kushaja kusina kukwana, nguva pfupi yekushanda, uye kunyange njodzi dzekuchengetedza. Kuti dambudziko iri rigadziriswe zvinobudirira, kushandisa Battery Management System (BMS) nekugadzirisa kwakanangana kwakakosha.

Chekutanga,shandisa basa rekuenzanisa reBMS. BMS yepamusoro (seyakaita seyemagetsi ane simba rekugadzirisa magetsi) inotamisa simba kubva kumasero ane simba remagetsi akawanda kuenda kune ane simba remagetsi mashoma panguva yekuchaja/kuburitsa magetsi, zvichideredza kusiyana kwesimba. Kune BMS isingashande, ita "full-charge static balancing" pamwedzi—rega bhatiri rimire kwemaawa 2-4 mushure mekuchaja zvakakwana kuti BMS ienzanise voltages.

Chechipiri, tarisa kubatana uye kugara zvakanaka kwemasero. Mabhazi emhangura asina kusimba kana nzvimbo dzakasviba dzekubatana dzinowedzera kuramba, zvichiwedzera kudonha kwemagetsi. Chenesa kubatana nedoro uye simbisa nzungu; tsiva zvikamu zvakaora. Zvakare, shandisa masero e-lithium akafanana (akaedzwa kuti aone kana ≤5% kutsauka kwekudzivirira kwemukati) kudzivirira kusawirirana kuripo.

Chekupedzisira, gadzirisa mamiriro ekuchaja nekuburitsa magetsi. Dzivisa mashandiro emagetsi ane simba guru (semuenzaniso, kukurumidza kweEV) sezvo magetsi akawandisa achiwedzera kuderera kwemagetsi. Shandisa machaja anodzorwa neBMS anotevera "pre-charge → constant current → constant voltage", zvichideredza kuunganidzwa kwemagetsi asina kuenzana.

Nekubatanidza mashandiro eBMS nekugadzirisa kwakanyatsonaka, unogona kugadzirisa kusawirirana kwemagetsi uye kuwedzera hupenyu hwebhatiri re lithium.
