With the rapid development of mobile energy storage technology and electric vehicle technology, there are higher requirements on the flexible and convenient interface of mobile energy storage vehicle. This paper presents a gun/seat integrated control system for mobile energy storage vehicle. The integrated system model of the charging gun/charging base is established, the principle block diagram is drawn, the recognition principle and discrimination method of the plug-in state of the double head gun are analyzed, and the vehicle/pile switching function and anti-reverse connection function are designed under the condition of meeting the national standard. The main controller coordinates and controls the charging process of the charging pile and the power supplement process when it is used as a mobile energy storage vehicle. The converter is the hub of the mobile energy storage vehicle and the power grid. Through the real-time sampling of the power grid information and the double loop control strategy, the mobile energy storage vehicle has the power quality control functions such as reactive power compensation, harmonic control and imbalance control while completing its normal functions.
