The patent application number is CN202011205848. X, and the authorization date is May 14, 2024.

Patent Abstract: This application provides a charging station system and a charging station power distribution control method, wherein the charging station comprises at least one AC/DC submodule and at least one DC/DC submodule; All input terminals of AC/DC submodules are connected to AC power supply, and the output terminals of all AC/DC submodules are connected to the DC bus of the charging station system. At the same time, the input terminals of all DC/DC submodules are connected to the above DC bus, and the output terminals of all DC/DC submodules are connected to the output terminals of the charging station system. All AC/DC submodules in this scheme are connected to the same DC bus, jointly inputting energy to the DC bus to ensure the energy requirements of all DC/DC submodules. The scheme flexibly allocates AC/DC submodules participating in charging work according to charging needs, ensuring that the load rate of AC/DC submodules is maintained near the optimal efficiency point, thereby improving the overall efficiency of AC/DC submodules and improving the overall efficiency of the entire charging pile system.
