New energy vehicles refer to all other energy vehicles except gasoline and diesel engines. The use of unconventional vehicle fuel as a power source, integrated vehicle power control and drive advanced technology, the formation of advanced technical principles, with new technology, new structure of the car. In the energy shortage, environmental pollution is becoming more and more serious today, new energy electric vehicles have become the future development trend of the automobile industry. Of course, this trend has also led to the popularity of charging piles in various public places.
The function of the charging pile is similar to that of the refueling machine in the gas station, which can be fixed on the ground or the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. Charging piles can 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 electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interactive interface provided by the charging pile to carry out the corresponding charging mode, charging time, cost data printing and other operations. The charging pile display screen can display the charging amount, cost, charging time and other data.
The particularity of charging pile structure determines that the automatic communication system is characterized by wide coverage and short communication distance. And with the development of the city, the network topology requires a flexible and expandable structure, therefore, the choice of charging pile communication mode should consider the following aspects: 1, the reliability of communication - the communication system to long-term strong electromagnetic interference or noise interference test, and maintain the smooth communication. 2, construction costs - under the premise of meeting the reliability, comprehensive consideration of construction costs and long-term use and maintenance costs. 3, two-way communication - not only to achieve the upload of information, but also to achieve the control of the amount of delivery. 4, multi-service data transmission rate - with the continuous growth of terminal business volume in the future, the communication between the main station to the sub-station and the sub-station to the terminal requires more and more high data transmission rate to achieve multi-service. 5, communication flexibility and scalability - because the charging pile has the characteristics of multiple, wide and dispersed control points, it requires the use of standard communication protocols, with the development of "ALLIP" network technology trend and the continuous growth of power operation business, it is necessary to consider the IP-based service bearing, and it is required to facilitate installation, construction, commissioning, operation and maintenance.
The high-standard communication requirements of the charging pile also determine the strictness of its construction and production requirements. The manufacturing of charging pile has very strict requirements for production technology, manufacturing process and production control management. In the process of manufacturing and producing charging piles, they must be carried out in strict accordance with various standards. The assembly of a charging pile is a more complex process, which is a process engineering that combines various types and a large number of electronic components, mechanical installations, wires, terminals, connectors, other materials, etc., with different connection methods and installation methods, in stages and steps. Among them, the processing of various wires, wire harness processing, ground molding, wire and terminal crimping and other processes are very critical steps, if the quality is not up to standard, it will make the entire charging pile there are serious security risks. The American military standard crimping tool produced by Jiaxing Jingrui Instrument Equipment Co., Ltd. can complete the crimping work of the charging pile wire perfectly and efficiently, which is of great significance to improve the overall quality of the charging pile wire harness, thus playing a positive role in promoting the development of the entire electric vehicle industry, and contributing to the popularity of new energy vehicles in China. The US Army standard series of crimping pliers are also widely used in aviation connectors, military connectors, circular connectors, rectangular/heavy duty connectors, RF coaxial connectors, printed circuit board connectors, automotive connectors, fiber optic connectors in the crimping of terminals and wires. In addition, in order to further expand the scope of application of crimping tools, we have specially designed and launched a series of customized crimping tools according to customer needs at home and abroad by changing the scope of wire crimping and expanding the diameter of the through hole, including manual crimping pliers, pneumatic crimping pliers, pneumatic bench crimping machine, etc., which greatly enriches the types of products.
In short, as a green vehicle with broad development prospects, the popularity of electric vehicles will be extremely rapid in the future, and the future market prospects are also extremely huge. Therefore, charging piles will become more and more popular. How to ensure the safety and quality of charging pile is a problem that cannot be ignored.
