A European standard-based double-gun high-power quick charging system and method are disclosed. The system includes a battery management system, and at least two paths composed of corresponding charging communication modules, chargers and high-voltage charging loops, each of the chargers connected to at least one charging gun; the battery management system independently controls the charging communication module and high-voltage charging loop, and performs mapping management on a control signal and high-voltage charging loop; information interaction between different charging control units and chargers is carried out independently. By designing the system compatibility and time sequence difference when a double-gun system is connected, the problem of idle chargers is solved, so that the charging speed is increased, and the problems of long-time occupation of charging resources by vehicles and low utilization efficiency of vehicles are avoided; insulation detection performed on the initial charging of vehicle battery system increases safety of the system.
