The construction requirements of automobile charging piles from the EV Charger Manufacturer, as the electric vehicle charging piles (plugs) on the electric side of the power grid, the particularity of the structure determines that the characteristics of the automatic communication system are that the points to be measured are large and scattered, the coverage is wide, and the communication distance is short. And with the development of the city, the network topology requires a flexible and expansive structure. Therefore, the choice of the communication mode of the Electric Vehicle Charging Station (plug) should consider the following problems:
(1) Reliability of communication – Communication systems must withstand harsh environments and strong electromagnetic interference or noise interference for a long time, and keep communication open.
(2) Construction costs – comprehensive consideration of construction costs and long-term use and maintenance costs, provided that reliability is met.
(3) Two-way communication - not only can the upload of information, but also the release of control volume.
(4) Multi-service data transmission rate - With the continuous increase of terminal traffic, the communication between the primary station and the sub-station and the sub-station to the terminal has higher and higher requirements for realizing the data transmission rate of multiple services.
(5) Communication flexibility and scalability - Because charging piles (plugs) have the characteristics of multiple control points, wide area and dispersion, standard communication protocols are required, along with the development of "ALL IP" network technology trends As well as the continuous growth of power operation business, it is necessary to consider the IP-based service bearer, and at the same time require easy installation, commissioning, operation, and maintenance.
The above is the requirement for building Charging Station for Cars. Now the progress of the times, the development of science and technology, more and more means of transportation in our lives, electric vehicles are one of them, so there is the emergence of car charging piles. When constructing a car charging pile, it is necessary to strictly follow the above requirements.
