ABSTRACT Method for high-rate charging of batteries with sealed cells, whereby through supplied charging current the efficiency the single battery cell is actively influenced such that the charging time and temperature rise of the cell is minimized such that in a first step the battery is dis- charged to a voltage UB slightly higher than a first reference voltage (UO) whereafter in a first recharging step the supplied charging current IB is controlled progressively increasing according to the function IB = k (UB - UO) where k is an adjusted constant, until the pole voltage has reached a second reference voltage UB = ? where ? is maximum battery voltage and in a second charging step the charging current IB is controlled through voltage feedback such that UB = ? whereby the amount of the supplied charging current is determined by the charging state of the battery cells. The first and second charging step can also be repeated with a fixed time interval with a free running time interval without charging current a number of cycles until a state of full charge is reached.
