Abstract
(EN)
Provided by the present application are a quick charging method for a battery, a charging device, a device to be charged and a charging system. The quick charging method for the battery comprises: acquiring status parameters of a battery in a device to be charged, wherein the status parameters of the battery comprise the present temperature of the battery; selecting a charging cutoff voltage corresponding to the current temperature from a target parameter mapping relationship, wherein the charging cutoff voltage is greater than the rated voltage of the battery; and charging the battery at a constant current until the voltage of the battery reaches the charging cut-off voltage, and then stopping charging of the battery, which may thus increase the time of constant current charging at a high current, thereby effectively increasing the charging speed. In addition, the cut-off voltage for charging is flexibly adjusted by means of the temperature of the battery, which prevents the battery from overvoltage damage and ensures that the battery is at full capacity.

L'invention concerne un procédé de charge rapide d'une batterie, un dispositif de charge, un dispositif à charger et un système de charge. Le procédé de charge rapide de la batterie consiste à : acquérir des paramètres d'état d'une batterie dans un dispositif à charger, lesdits paramètres d'état de la batterie comprenant la température courante de la batterie; sélectionner une tension de coupure de charge correspondant à la température courante d'après une relation de correspondance d'un paramètre cible, la tension de coupure de charge étant supérieure à la tension nominale de la batterie; et charger la batterie à courant constant jusqu'à ce que la tension de la batterie atteigne la tension de coupure de charge, puis arrêter la charge de la batterie, ce qui peut augmenter le temps d'une charge en courant constant effectuée à un niveau de courant élevé, et donc augmenter efficacement la vitesse de charge. De plus, la tension de coupure pour la charge est réglée de manière souple au moyen de la température de la batterie, ce qui évite les surtensions pouvant endommager la batterie et assure la pleine capacité de la batterie.
