Embodiment
[0043] Exemplarily, the black device in FIG. 1 is a charging base, and the gray device is a charging plug. Two EVCC, two
[0044] Optionally, an electronic lock is provided on the charger, and the electronic lock is locked when a communication signal is generated.
[0045] The electronic lock is a hardware mechanical lock, which is locked when entering data interaction to prevent the charging gun from being pulled and inserted by mistake.
[0048]
[0051] Step 2, wait for the gun insertion signal, enter the charging mode when detecting the gun insertion signal, and interlock the discharge.

The invention discloses a high-power fast charging system and method based on European standard double guns. The system includes: a battery management system, and at least two corresponding charging communication modules, a charger and a charging high-voltage circuit. Each charger is used for Connect at least one charging gun; the battery management system independently controls the charging communication module and the charging high-voltage circuit, and performs mapping management on the control signal and the charging high-voltage circuit; the information exchange between different charging control units and the charger is independent conduct. By designing the system compatibility and timing difference when the dual-gun system is connected, the problem of idle charging is solved, making the charging speed faster, avoiding the problem that the vehicle occupies charging resources for a long time and the vehicle utilization efficiency is not high; the vehicle battery system Insulation detection is performed on the initial charging, which increases system safety.
Description
A high-power fast charging system and method based on European standard double guns technical field [0001] The invention belongs to the technical field of charging, and relates to a high-power fast charging system and method based on European standard dual guns. Background technique [0002] At present, the new energy vehicle adopts the European standard DC charging, and the single-gun charging method is adopted. Based on current new energy vehicles The power of the vehicle is gradually increased, and the single-gun charging of European standard is adopted. The charging time is long, and the charging resources need to be occupied for a long time, and the vehicle utilization rate reduce, affect operation, etc.; and when power type power battery is used, the power performance of power battery is not fully developed. wave, affecting the efficiency of use. European standard charging requires system insulation detection to be completed by the charger, so the vehicle does no...
