The invention discloses a photovoltaic energy storage charging station energy management system and a control method. The system comprises a light storage management module, a switch management module and a charging pile management module which are controlled by the energy management system. The optical storage management system controls the battery pack management module, the MPPT module and the inverter management module; the battery pack management module controls the battery management module and the DC/DC in the energy storage module; the inverter management module controls the inverter; all the control modules are connected through a high-speed CAN bus; the energy storage module comprises an echelon utilization battery pack, a battery management module and a DC/DC; the photovoltaic system is connected in series with the MPPT module, then is connected in parallel with the energy storage module, and then is connected with the inverter; and the switch cabinet is respectively connected with the inverter and the power grid power supply. Energy management of different SOCs of the echelon batteries can be achieved, the operation efficiency of the echelon battery energy storage system with the large SOC difference is improved, the service life of the echelon battery energy storage system with the large SOC difference is prolonged, and the electricity utilization cost of a charging station can be effectively reduced through access deployment of a photovoltaic power grid and an external power grid.
