발명의 명칭: (EN) LITHIUM ION BATTERY CHARGING METHOD
(FR) PROCÉDÉ DE CHARGE DE BATTERIE AU LITHIUM-ION
(ZH) 锂离子电池充电方法
요약서:
(EN) Provided is a lithium ion battery charging method. The method comprises: at various pulse charging stages, charging a lithium ion battery in a positive and negative pulse current alternating manner, and stopping charging when the voltage of the lithium ion battery reaches a cut-off voltage value corresponding to a current pulse charging stage. Positive pulse current values corresponding to the various pulse charging stages gradually reduce, cut-off voltage values corresponding to the various pulse charging stages gradually increase, and negative pulse current values corresponding to the various pulse charging stages are less than positive pulse current values corresponding to corresponding pulse charging stages. The technical solution provided in the present invention can improve the anode lithium analysis phenomenon, and also improve the speed of charging a lithium ion battery.
(FR) L'invention concerne un procédé de charge de batterie au lithium-ion. Le procédé consiste à : à divers étages de charge d'impulsion, charger une batterie au lithium-ion de manière alternée en courant d'impulsion positif et négatif, et arrêter la charge lorsque la tension de la batterie au lithium-ion atteint une valeur de tension de coupure correspondant à un étage de charge d'impulsion de courant. Les valeurs de courant d'impulsion positif correspondant aux divers étages de charge d'impulsion se réduisent progressivement, les valeurs de tension de coupure correspondant aux divers étages de charge d'impulsion augmentent progressivement, et les valeurs de courant d'impulsion négatif correspondant aux divers étages de charge d'impulsion sont inférieures aux valeurs de courant d'impulsion positif correspondant aux étages de charge d'impulsion correspondants. La solution technique selon la présente invention peut améliorer le phénomène d'analyse de lithium d'anode, et améliorer également la vitesse de charge d'une batterie au lithium-ion.
(ZH) 本发明提供一种锂离子电池充电方法,该方法中,在各脉冲充电阶段,以正负脉冲电流交替的方式对锂离子电池进行充电,直到锂离子电池的电压达到当前脉冲充电阶段对应的截止电压值时停止充电。各脉冲充电阶段对应的正脉冲电流值依次减小,各脉冲充电阶段对应的截止电压值依次增大,且各脉冲充电阶段对应的负脉冲电流值小于相应的脉冲充电阶段对应的正脉冲电流值。本发明提供的技术方案能够改善阳极析锂现象,还提高了对锂离子电池的充电速度。
