Charging pile communication system and charging pile communication method Technical Field The invention relates to a charging pile management technology, and in particular relates to a charging pile communication system and a charging pile communication method. Background In order to reduce carbon emissions and improve global warming problems, the development of electric vehicle technology has been actively promoted in the world, and long-term targets of prohibit selling fuel vehicles have been set. Policy and auxiliary measures are formulated by governments and industry in various countries so as to accelerate popularization and market growth of electric vehicles. However, with the rapid increase in the number of electric vehicles, the expansion and management of charging infrastructure faces many challenges, particularly in terms of network connection and charging scheduling of charging piles. More specifically, as the number of charging posts grows, a reliable and stable communication architecture is necessary to ensure that all charging posts can report the state of charge to the central management system in real time or receive scheduling instructions from the central management system in real time. When a large number of charging piles are required to communicate with a central management system through a mobile communication network, not only are all the charging piles required to have mobile communication capability, but also a huge burden is imposed on basic equipment (e.g., base stations, etc.) in the mobile communication network. Furthermore, when each charging pile has mobile communication capability, not only hardware cost is increased, but also high mobile data traffic cost is generated, which is a heavy burden for charging station operators. In addition, when a large number of charging piles are required to communicate with the central management system through the mobile communication network, a large number of data transmission demands are generated, which may cause overload of the base station, so that communication quality is degraded or transmission delay is increased. Disclosure of Invention In view of the above, the present invention provides a charging pile communication system and a charging pile communication method, which enable a plurality of client charging piles to communicate with a charging pile management server through a gateway charging pile by using a layered charging pile communication architecture, so that a plurality of charging piles share mobile communication network resources. The embodiment of the invention provides a charging pile communication system which comprises a first gateway charging pile and a plurality of first customer charging piles. The first gateway charging stake is communicatively connected to a charging stake management server. The plurality of first customer charging piles are communicatively connected to the first gateway charging pile. The first gateway charging stake is configured to charge current with the first gateway charging stake and the plurality of first customer charging stakes in the first charging stake group based on a total current limit of the first charging stake group. From another perspective, the embodiment of the invention provides a charging pile communication method, which is suitable for a charging pile communication system. The method comprises the following steps. The charging stake is communicatively connected to a charging stake management server by a first gateway. A plurality of first customer charging piles are communicatively connected to the first gateway charging piles. And configuring charging current of the first gateway charging pile and the plurality of first customer charging piles in the first charging pile group by the first gateway charging pile based on the total current limit of the first charging pile group.
