Abstract
A method for charging a battery cell is provided. During a charging phase at a constant charging current, monitoring is carried out to ascertain whether a charging voltage applied to the battery cell reaches or exceeds a predefined switchover voltage, and, if this is the case, a switchover is made to the next charging phase at a lower constant charging current. During the charging phases, additional monitoring is carried out to ascertain whether the difference between the charging voltage and the switchover voltage of this charging phase reaches or falls below a predefined value, and, if so, at least one discharge pulse is applied to the battery cell.
