Abstract
(EN)
A method for detecting the charge level of a battery, comprising: after a pre-set time interval, re-calculating a first charge level value based on the pre-set time interval and a current value and a second charge level value of the battery at the previous moment, re-determining the current value and the second charge level value of the battery according to the first charge level value currently obtained by calculation, and finally determining an charge level indication value of the battery according to the currently calculated second charge level value, thereby increasing the accuracy of detection of the charge level of the battery, so that the charge level of the battery can also be detected in the case where the battery capacity is unknown, and the generality is relatively high. Also provided are a system for detecting charge level of a battery and a battery.

L'invention concerne un procédé pour détecter le niveau de charge d'une batterie, comprenant : après un intervalle de temps prédéfini, le nouveau calcul d'une première valeur de niveau de charge en se basant sur l'intervalle de temps prédéfini et d'une valeur actuelle et d'une seconde valeur de niveau de charge de la batterie à l'instant précédent, la nouvelle détermination de la valeur actuelle et de la seconde valeur de niveau de charge de la batterie en fonction de la première valeur de niveau de charge actuellement obtenue par calcul, et enfin la détermination d'une valeur d'indication de niveau de charge de la batterie en fonction de la seconde valeur de niveau de charge calculée actuelle, ce qui permet d'augmenter la précision de détection du niveau de charge de la batterie, de sorte que le niveau de charge de la batterie peut également être détecté dans le cas où la capacité de la batterie est inconnue, et la généralité est relativement élevée. L'invention concerne également un système de détection de niveau de charge d'une batterie et une batterie.
