The embodiment of the invention relates to the technical field of charging systems, in particular to a power distribution control method, a charging host, charging equipment and a chip. The power distribution control method comprises the following steps: receiving a bus charging enable signal used for representing the use state of each power bus, a switch state signal used for representing the closing state of each switch, and a switch control signal used for indicating to close at least one specified switch; according to the switch state signal and the bus charging enable signal, whether the switch control signal accords with a pre-configured target interlocking logic is judged, and the target interlocking logic is matched with a topological structure of a power distribution matrix and is used for preventing abnormal series connection between power buses of the power distribution matrix; and if yes, controlling the specified switch to be closed according to the switch control signal. According to the invention, the interlocking logic judgment is carried out on the switch control signal, so that abnormal series connection of different power buses in the actual use process is avoided, and the reliability and safety of the whole system are improved.
本发明实施例涉及充电系统技术领域,具体涉及一种功率分配控制方法、充电主机、充电设备及芯片。该功率分配控制方法包括:接收用于表示各路功率母线的使用状态的母线充电使能信号、用于表示各个开关的闭合状态的开关状态信号、用于指示闭合至少一个指定开关的开关控制信号;根据开关状态信号及母线充电使能信号判断开关控制信号是否符合预配置的目标互锁逻辑,目标互锁逻辑匹配功率分配矩阵的拓扑结构,用于防止功率分配矩阵的功率母线之间存在异常串联;若是,则根据开关控制信号控制指定开关闭合。本发明通过对开关控制信号进行互锁逻辑判断,以避免不同功率母线在实际使用过程中出现异常串联,从而提高整个系统的可靠性和安全性。
