Abstract
The method for determining the end-of-discharge voltage threshold of a rechargeable battery includes discharging the battery up to a predefined end-of-discharge voltage threshold, at least partially charging the battery, determining, while at least partially charging the battery, an electrical parameter representative of a coup de fouet effect, which coup de fouet effect appears during the partial charging, comparing said electrical parameter with a predetermined characteristic and updating the end-of-discharge voltage threshold to be used for subsequent discharging according to the result of said comparison.
