Abstract
A method of charging a battery in which the end of charging is determined by detecting variations in the battery temperature includes the following steps: entering a charging mode, periodically measuring the battery temperature, measuring the variation in the battery temperature per unit time, comparing the battery temperature variation per unit time to a first threshold corresponding to variation of the ambient temperature and the battery temperature, and in this case terminating the charging mode, and to variation of only the ambient temperature, and in this case comparing the battery temperature variation per unit time to a second threshold corresponding to variation of only the battery temperature and terminating the charging mode.

A method of charging a battery in which the end of charging is determined by detecting variations in the battery temperature, said method including the following steps:
- a) entering a charging mode,
- b) periodically measuring said battery temperature,
- c) measuring the variation in said battery temperature per unit time,
- d) comparing said battery temperature variation per unit time:
- d1) to a first threshold corresponding to variation of the ambient temperature and the battery temperature, and in this case:
- terminating said charging mode, and
- d2) to variation of only the ambient temperature, and in this case:
- comparing said battery temperature variation per unit time to a second threshold corresponding to variation of only the battery temperature, and
- terminating said charging mode.
