The installation requirements of the charging pile in the parking lot are considered by many people to be a simple matter. They just drill a few holes on the ground to fix the charging pile, and then pull a wire! But in fact, the coordination workload in the early stage is very large. Because it will involve multiple departments, such as power companies and properties. First of all, the installation of charging piles in the parking lot is required to go to the power company to file an application, then transfer it to the power supply bureau, and finally wait for the technical engineer to come to the site and propose a construction plan. It should be noted that the consent of the property owner is required, that is, the consent of the community developer must be obtained. 1. The installation requirements of the charging pile in the parking lot are as follows: 1. It is forbidden to use the connection method of straight-through cable and ordinary household plug with potential safety hazards. 2. The charging method greater than 16 amps requires the installation of electronic locks and temperature sensors on the vehicle socket and power socket. 3. An electronic lock should be installed in the DC charging gun, and the mechanical structure of the electronic lock should be reserved for the vehicle socket. 4. Vehicles and facilities are required to have detection and alarm functions. 5. In order to prevent electric leakage accidents, it is stipulated that chargers and vehicles must have the functions of insulation detection and electric energy discharge. 6. In order to improve the compatibility and charging efficiency of facilities and vehicles, the classification of charging voltage is stipulated. 7. Add communication version control for DC charging, and clarify the charging sequence logic and time definition. 2. The installation of charging piles in the parking lot needs to consider the following issues: 1. Communication reliability The communication system must withstand the test of harsh environments and strong electromagnetic interference or noise interference for a long time, and maintain smooth communication. 2. Construction cost On the premise of satisfying the reliability, comprehensively consider the construction cost and the cost of long-term use and maintenance. 3. Two-way communication can not only realize the upload of information volume, but also realize the release of control volume. 4. Multi-service data transmission rate With the continuous growth of terminal traffic in the future, the communication between the master station and the sub-station and the sub-station to the terminal requires higher and higher data transmission rates for multi-service. 5. Flexibility and scalability of communication Since the charging pile has the characteristics of many control points, wide area and decentralization, it is required to adopt a standard communication protocol.“ALL IP”With the development of network technology trends and the continuous growth of power operation services, it is necessary to consider IP-based service bearer, and at the same time require easy installation, construction, commissioning, operation, and maintenance.
