Light storage and charging integrated charging system based on reconstruction module and efficiency improvement method thereof

The invention discloses an optical storage and charging integrated charging system based on a reconfiguration module and an efficiency improving method thereof, belongs to the technical field of new energy charging, and solves the problems that a charging station system architecture does not consider the efficiency characteristic of an AC/DC module, so that the output power setting ratio is unreasonable, and the charging efficiency of the system is influenced. The AC bus is respectively connected with an AC power grid and a plurality of groups of AC/DC modules, the plurality of groups of AC/DC modules are connected with a plurality of groups of fling-cut switches, the AC/DC modules are connected with the fling-cut switches in a one-to-one correspondence manner, the plurality of groups of fling-cut switches are connected in parallel and then are connected with a DC bus, and the DC bus is respectively connected with a photovoltaic power generation unit, an energy storage unit and a plurality of groups of chargi
