Charging station system and control method

The invention discloses a charging station system which comprises a charging pile, a sub grid module, a main grid module, a data acquisition device and a server. The sub grid module and the main grid module are connected with the charging pile. The data acquisition device is connected with the main grid module. The server is connected with the data acquisition device. The sub grid module and the main grid module are micro power wireless data transmission modules and are used for establishing wireless connection based on a ZigBee protocol stack and transmitting data generated in a charging process. The invention further provides a charging station system control method. According to the charging station system and the control method thereof, which are provided by the invention, the charging pile and the data acquisition device are in wireless transmission and are not easily affected by terrain; device cost and construction cost are low; the charging station system can be conveniently installed; the construction process of the charging station system can be accelerated; and the charging station system has the advantages of accurate information transmission, high efficiency and reduced late maintenance cost.
