A device for determining the charge state of an accumulator and having a charging current supply unit that can be operated in a plurality of charging modes is provided. When the storage charge mode is activated, the accumulator is charged only up to a predefined, optimized partially charged state. If the charge state determined at the start of the storage charge mode is higher than the predefined partially charged state, then the discharging device discharges the accumulator as far as the predefined partially charged state.

1. A charging device for charging an accumulator having at least one rechargeable battery cell, comprising: a charging current supply unit that is operable in a plurality of charging modes, the plurality of charging modes selectable by a user;a discharging device provided for at least one of the charging modes; anda determining device for determining a charge state of the accumulator, having a storage charging mode,wherein when the storage charging mode is activated, the accumulator is only charged to a predetermined partial charge state that is optimized with regard to a foreseeable storage of the accumulator, andwherein if the charge state determined by the determining device at a beginning of the storage charging mode is higher than the predetermined partial charge state, the discharging device discharges the accumulator to the predetermined partial charge state. 2. The device as recited in claim 1, wherein the determining device determines the charge state based on the accumulator's voltage. 3. The device as recited in claim 2, wherein the charging modes additionally include a quick charging mode in which the accumulator is only charged to a predetermined partial charge state that is optimized with regard to the charging duration and the level of the achievable charge state. 4. A system for charging an accumulator, equipped with a device as recited in claim 2, in which the accumulator is implemented using a technology, in particular a lithium-ion technology, in which storage of the accumulator in a non-optimal charge state leads to a more pronounced aging of the accumulator. 5. The device as recited in claim 1, wherein the determining device determines the charge state by evaluating information that is transmissible to the device for determining the charge state from charge state electronics that balance the charge state and are integrated into the accumulator. 6. The device as recited in claim 5, wherein the charging modes additionally include a quick charging mode in which the accumulator is only charged to a predetermined partial charge state that is optimized with regard to the charging duration and the level of the achievable charge state. 7. The device as recited in claim 6, wherein the charging modes additionally include a gentle charging mode in which the accumulator is charged to a partial charge state that is a predetermined distance from a charge state in which the accumulator is considered to be fully charged. 8. The device as recited in claim 7, wherein the charging modes are manually selectable by means of an adjusting device or by inserting the accumulator into a charging slot provided for the particular charging mode. 9. The device as recited in claim 8, wherein means are provided for detecting a coding that is present on or in the accumulator and a coding is associated with a particular charging mode or with particular charging modes so that it is only possible to select and/or activate these charging modes to charge the accumulator. 10. A system for charging an accumulator, equipped with a device as recited in claim 5, in which the accumulator is implemented using a technology, in particular a lithium-ion technology, in which storage of the accumulator in a non-optimal charge state leads to a more pronounced aging of the accumulator. 11. The device as recited in claim 1, wherein the charging modes additionally include a quick charging mode in which the accumulator is only charged to a predetermined partial charge state that is optimized with regard to the charging duration and the level of the achievable charge state. 12. The device as recited in claim 1, wherein the charging modes additionally include a gentle charging mode in which the accumulator is charged to a partial charge state that is a predetermined distance from a charge state in which the accumulator is considered to be fully charged. 13. The device as recited in claim 1, wherein the charging modes are manually selectable by means of an adjusting device or by inserting the accumulator into a charging slot provided for the particular charging mode. 14. The device as recited in claim 1, wherein means are provided for detecting a coding that is present on or in the accumulator and a coding is associated with a particular charging mode or with particular charging modes so that it is only possible to select and/or activate these charging modes to charge the accumulator. 15. A system for charging an accumulator, equipped with a device as recited in claim 1, in which the accumulator is implemented using a technology, in particular a lithium-ion technology, in which storage of the accumulator in a non-optimal charge state leads to a more pronounced aging of the accumulator. 16. The device as recited in claim 1, wherein the predetermined partial charge state that is optimized with regard to the foreseeable storage of the accumulator is approximately 30% of a possible charge status. 17. The device as recited in claim 1, wherein the accumulator has only one rechargeable battery cell.
