| 摘要 |
The invention relates to a method for estimating the state of health (SOH) of a battery, characterised by comprising the following steps: a first phase of calibrating (P1) one or more batteries of the same family of batteries, making it possible to determine a favourable range for estimating the state of health of a certain family of batteries, the favourable range corresponding to a partial charge or discharge of a battery, and to determine reference data; a second phase of measuring and estimating (P2) the state of health of the battery, comprising the steps of measuring (E14) at least one value linked to the quantity of charge or energy supplied or delivered by the battery in a partial discharge or charge phase of the battery over the favourable range, and estimating (E16) the state of health of the battery based on the result of the measurement step (E14) and the reference data established during the first calibration phase. |
