When the smart charging pile is in use, place the electric vehicle charging pile on the pallet, and at the same time use the bracket to support the waterproof cloth to cover the charger, which effectively prevents rain or water from spilling on the charger. The supporting plate is raised, so that the water flow can flow through the bottom of the supporting plate, so as to avoid the flooding of the supporting plate when the water flow is too large, and the car owner does not stop and charge according to the standard, which is the original cause of the electric vehicle fire. Inferior electric vehicle products are short-circuited in bad weather, especially when they are charging, they are more likely to cause fire accidents. In addition, not all charging piles from new energy charging pile manufacturers can charge safely. I am worried that an accidental fire will occur for some reason when the owner uses the charging pile to charge the electric vehicle, causing unnecessary trouble. Generally, charging piles are installed in residential areas, commercial circles, campuses, streets and other areas where electric vehicles are concentrated, mainly in old residential areas, where there are no carports, and there is no centralized parking area for electric vehicles. Charging piles cannot be installed. Or other important lines conflict with the direction of the charging pile and cannot be changed, so the charging pile cannot be installed. Due to the small number of vehicles and small charging demand in individual communities, there is no need to install electric piles for car charging piles in the community. Waste, unattended disposal. With the development of the city, the network topology requires a flexible and scalable pure electric vehicle charging pile structure. Therefore, the selection of the electric vehicle charging pile (bolt) communication method should consider the following issues: (1) Communication reliability——The communication system has to withstand the test of harsh environment and stronger electromagnetic interference or noise interference than the charging pile solution for a long time, and keep the communication smooth. (2) Construction costs——On the premise of satisfying the reliability, comprehensively consider the construction cost and the long-term use and maintenance cost of the charging pile. (3) Two-way communication——Not only can upload the amount of information, but also realize the release of the amount of control. (4) Multi-service data transmission rate—Charging pile customization—With the continuous growth of the terminal business volume in the future, the communication between the main station and the sub-station, and the sub-station to the terminal requires higher and higher data transmission rates to realize multi-service. (5) Flexibility and scalability of communication charging pile ODM——Since the car charging pile (bolt) has the characteristics of many control points, wide area and dispersion, it is required to adopt a standard communication protocol.“ALLIP”With the development of network technology trends and the continuous growth of power operation business, IP-based service bearer needs to be considered, and at the same time, it is required to facilitate installation, commissioning, operation, maintenance, and OEM of charging piles.
