Abstract

Per equalizzare la tensione di batterie connesse in serie in fase di ricarica si misura la tensione e la temperatura di ogni batteria e si carica con corrente di intensità maggiore solo quella a tensione minore, applicando alle altre batterie un by-pass di corrente; si ripetono le operazioni fino a quando tutte, le batterie hanno raggiunto la stessa tensione rapportata alla temperatura misurata.(Figura 2).
