Charging method and system

The invention discloses a charging method and system, and the method comprises the steps: obtaining a first state parameter of a to-be-charged battery in a pre-charging stage, and enabling the first state parameter to be used for representing the aging degree of the to-be-charged battery; based on the first state parameter, determining a target charging current peak value of the to-be-charged battery in a constant-current charging stage and/or a target charging voltage peak value of the to-be-charged battery in a constant-voltage charging stage; and charging the battery to be charged based on the target charging current peak value and/or the target charging voltage peak value. 本申请公开了一种充电方法和系统，所述方法包括：在预充电阶段，获取待充电电池的第一状态参数，所述第一状态参数用于表征所述待充电电池的老化程度；基于所述第一状态参数，确定所述待充电电池在恒流充电阶段的目标充电电流峰值和/或在恒压充电阶段的目标充电电压峰值；基于所述目标充电电流峰值和/或目标充电电压峰值，对所述待充电电池进行充电。
