摘要： The invention relates to a method for adaptively charging rechargeable cells, in particular lithium-ion cells. The present invention further relates to an apparatus for charging cells of this kind. In order to specify a method for charging a lithium-based cell and, respectively, an apparatus for charging a lithium-based cell, in which method and apparatus the capacitance of the cell is utilized in an optimum manner, the charging time is drastically reduced, the service life of the cell is extended, degeneration of a charged cell is virtually prevented and/or the capacitance of the cell can be increased, the invention specifies a method which comprises the steps of: pulsed charging of the cell, wherein the charge current
IL exceeds the rated charge current
ILmax of the cell during the charge pulse (31); and the cell is discharged by means of load pulses (32) between the charge pulses (31).-

摘要： The invention relates to a method for charging rechargeable cells, in particular lithium ion cells. The present invention also relates to an apparatus for charging such cells. In order to specify a method for charging a lithium-based cell and an apparatus for charging a lithium-based cell, in which the capacitance of the cell is optimally used, the charging time is drastically shortened, the shelf life of the cell is extended and/or it is possible to increase the capacitance of the cell, a method is stated which comprises the following steps: pulsed charging of the cell, wherein the charging current I
L exceeds the nominal charging current I
Lmax of the cell during the charging pulses (31); and the cell is discharged between the charging pulses (31) using load pulses (32).
