Abstract
The method for controlling the end of discharge of a rechargeable battery according to the invention comprises determining the transition frequency of the battery and determining an end-of-discharge criterion of the battery according to said transition frequency. Said end-of-discharge criterion is representative for example of a predetermined maximum value of the slope of the transition frequency. The transition frequency can be determined periodically during use of the battery, discharging being interrupted by regulating means according to said transition frequency.
