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

A method for determining the end-of-discharge voltage threshold of a rechargeable battery, comprising the following set of successive steps:
- discharging the battery up to a predefined end-of-discharge voltage threshold,
- at least partial charging of the battery,
- determining an electrical parameter representative of a coup de fouet effect on charging, at the beginning of said charging,
- comparing said parameter with a predetermined characteristic constituted by a threshold value or a range of values,
- updating the end-of-discharge voltage threshold to be used for subsequent discharging, according to the result of said comparison.
