The embodiment of the invention provides a charging control method and device, a control unit and a charging system, and relates to the technical field of charging piles. The method is applied to a control unit in a charging system, and comprises the following steps: acquiring distribution power units corresponding to a plurality of power interfaces in the charging system; determining a to-be-closed switch unit in the charging system according to the distribution power units corresponding to the plurality of power interfaces; determining whether there is a conflict between the charging paths of the target power interface after the to-be-closed switch unit is assumed to be closed; and if the to-be-closed switch unit assumes that no conflict exists among the charging paths of the plurality of power interfaces after the to-be-closed switch unit is closed, controlling the to-be-closed switch unit to execute a closing operation. According to the invention, whether the charging paths of the target power interfaces have conflicts can be judged in time based on the control unit, so that misjudgment of the control unit is avoided, and the situation that the same power unit is allocated to any two or more different power interfaces at the same time, so that the direct connection risk between the different power interfaces is caused is avoided.

    本申请的实施例提供了一种充电控制方法、装置、控制单元及充电系统,涉及充电桩技术领域。应用于充电系统中的控制单元,该方法包括:获取充电系统中多个功率接口对应的分配功率单元;根据多个功率接口对应的分配功率单元,确定充电系统中的待闭合开关单元;确定待闭合开关单元假设闭合后,目标功率接口的充电路径之间是否存在冲突;若待闭合开关单元假设闭合后多个功率接口的充电路径之间均不存在冲突,则控制待闭合开关单元执行闭合操作。本申请可基于控制单元及时判断目标功率接口的充电路径之间是否存在冲突,进而避免控制单元的误判,进而避免同一块功率单元同时分配给任意两个或多个不同的功率接口,进而导致不同功率接口之间发生直通风险。
