Abstract
This application provides a power distribution device, a charging device, an energy storage device, and a charging system. The power distribution device includes at least one power distribution unit, each power distribution unit including at least one power port, multiple load ports, at least one connection port, and a switch matrix. Each power port is used to connect to a power module in the charging device, and each load port is used to connect to a load. The switch matrix is used to disconnect or connect any two of each power port, each load port, and each connection port. At least one power distribution unit of the power distribution device includes a first power distribution unit, and one connection port of the first power distribution unit is used to connect to the power distribution units of other charging devices. This application embodiment can flexibly adjust the output power of the load ports of the power distribution device to meet the charging power requirements of different loads.
