The regulator shunts the portion of the trickle current which constitutes an excess to the charging current. There is thus provided an optimum charge for each cell, independent of differences in self-discharge of the different cells. The size of the shunted current is determined by the difference between the cell pole voltage and a reference voltage generated in the regulator. | |
