Abstract
The invention relates to a charging device for charging at least one rechargeable energy storage unit, having a defined inner resistance and having a compensation circuit for the compensation of a voltage drop during the charging operation caused by the inner resistance. The compensation circuit has a current detection for detecting a charge current of the rechargeable energy storage unit and a voltage regulator for adjusting the charge voltage to the detected charge current. The charging device is characterized in that the compensation circuit has a voltage distributor between the current detector and the voltage regulator, by the dimensioning of which the compensation of the inner resistance is carried out.

- 11. A charger for charging at least one rechargeable energy storage unit, having a defined internal resistance and having a compensation circuit for compensating for a voltage drop brought about by the internal resistance during a charging operation, in which the compensation circuit has a current detector which detects a charging current of the rechargeable energy storage unit and a voltage regulator which adapts the charging voltage to a detected charging current, the compensation circuit including a voltage divider, which is disposed between the current detector and the voltage regulator and by way of the dimensioning of the voltage divided the compensation for the internal resistance is effected.
