As of June 13, 2020, car charging piles are divided into two categories with different prices: the price of slow piles is between 500-3500 yuan; the price of fast piles is higher, 15KW generally costs about 10,000 yuan, plus about The construction side of 5,000 yuan needs a total of 15,000-20,000 yuan.The charging piles used in ordinary households are slow charging piles with various specifications, such as three-plug cables, power banks, standard AC piles, etc. The power supply is 220V, and the fast charging piles are generally commercial.
The electric vehicle charging pile (pile) is the infrastructure on the power distribution side of the power grid. The particularity of its structure determines that its automatic communication system has a multi-point, divided and scalable structure. Therefore, when choosing an electric vehicle charging pile (pile) ) communication methods should consider the following issues:
1. Reliability of communication
The communication network must withstand harsh environments and strong electromagnetic interference or noise interference for a long time to ensure the smooth communication of the communication network.
2. Construction cost
Considering the reliability, the construction cost and the long-term maintenance cost should be considered comprehensively.
3. Two-way communication
Not only can you check the upload of the amount of charging information through the mobile phone, but also can realize the release of the control amount.
4. Multi-service data transfer rate
Due to the continuous increase of terminal traffic in the future, the communication between the master station and the sub-station, and the communication between the sub-station and the terminal has higher and higher requirements for data transmission speed.
5. Flexibility and Extensibility of Communication
In view of the fact that charging piles (bolts) have many control surfaces, wide areas and scattered distribution, standard communication protocols are required. With the development of "ALLIP" network technology trends and the continuous growth of power operation services, it is necessary to consider IP-based service carrying , At the same time, it is required to facilitate installation, construction, commissioning, operation and maintenance.
The function of the charging pile is similar to that of the refueling device inside the gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. Charge various models of electric vehicles according to different voltage levels.The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle.
