The invention provides a charging management method, device and system, engineering machinery and a storage medium. The charging management method comprises the steps that the current first residual electric quantity of energy storage equipment on each branch in N branches connected in parallel is acquired, and the charging loads of all the branches are sequentially increased in the direction from the first branch to the Nth branch; according to the first residual electric quantity of the energy storage equipment on the (i + 1) th branch, the first residual electric quantity of the energy storage equipment on the ith branch and the preset charging current of the ith branch, the duration of the ith starting time period, # imgabs0 #, is determined; according to the sequence from the first starting time period to the (N-1) th starting time period, in the ith starting time period, the ith charging current is used for charging the energy storage devices on the first branch circuit to the ith branch circuit; and after N-1 initial time periods, charging the energy storage devices on the N branches according to a predetermined charging strategy.

    本公开提供一种充电管理方法、装置和系统、工程机械和存储介质。充电管理方法包括:获取并联的N条支路中的每条支路上的储能设备当前的第一剩余电量,其中在从第1条支路至第N条支路的方向上,每条支路的充电负荷依次增大;根据第i+1条支路上的储能设备的第一剩余电量,第i条支路上的储能设备的第一剩余电量,和第i条支路的预定充电电流,确定第i个起始时间段的时长,#imgabs0#;按照从第1个起始时间段至第N‑1个起始时间段的顺序,在第i个起始时间段内,利用第i个充电电流为第1条支路至第i条支路上的储能设备充电;在N‑1个起始时间段后,按照预定充电策略,为N条支路上的储能设备充电。
