Device for charging an accumulator and having a storage charge mode
First Claim
Patent Images
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; and
a 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.

Abstract
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.
