Embodiment Construction

[0027] The following describes several electric vehicle charging stations with different structures in combination with the accompanying drawings, and briefly explains the main features of the charging stations with various structures.

[0028] figure 1 It is a schematic diagram of the structure of the stand-alone isolated electric vehicle charging station system of the present invention. As shown in the figure, this type of charging station is mainly composed of a power supply system, several single-unit isolated high-frequency chargers and a charging station monitoring system.

[0029] The charging station is uniformly powered by the power supply system. The power supply system is composed of a high-voltage relay protection cabinet, an ordinary three-phase power transformer and a low-voltage relay protection cabinet; the high-voltage relay protection cabinet is connected between the high-voltage grid and the high-voltage side of the power transformer. The low-voltage side o...
