The high-voltage line of the electric vehicle is used to connect the charging interface with the battery, the interior of the battery, the battery and the engine as the carrier of power transmission. Due to the harsh automotive application environment, the high-voltage wire materials of electric vehicles play a very important role, and the performance requirements of materials are very high. This is one of the keys of electric vehicle high voltage line. Classification of high voltage lines for electric vehicles: the core component of new energy electric vehicles is batteries. The first high-voltage line used for battery connection of electric vehicle is an ordinary single-layer high-voltage line; The motor connection needs to prevent signal interference. OMG adds a shielded single-layer high-voltage line in the shielding layer; Due to the harsh application environment of electric vehicles, OMG has developed a double-layer high-voltage line with better temperature resistance, wear resistance and protection on the basis of single-layer high-voltage line. Therefore, we divide the common high-voltage lines of electric vehicles into three categories: single-layer electric vehicle high-voltage line, single-layer shielded electric vehicle high-voltage line and double-layer electric vehicle high-voltage line. Structural differences of three kinds of high voltage cables: XLPE, XLPE + tinned copper braid+ Aluminum foil + shell: XLPE, bare copper insulation: XLPE, outer skin: XLPE Single layer electric vehicle high voltage line: it is mainly used for the connection between equipment without shielding requirements, such as the connection between livestock batteries. Single layer shielded electric vehicle high voltage line; It is mainly used for the connection between equipment with shielding requirements, such as the connection between motor and frequency converter. Double layer electric vehicle high voltage line: mainly used in occasions with serious vibration environment, such as the connection between battery and high voltage.

As the electric vehicle charging pile (plug) on the distribution side of 1653 power grid, the particularity of its structure determines that the automatic communication system is characterized by many measured points, scattered, wide coverage and short communication distance. Moreover, with the development of the city, the network topology requires a flexible and extensible structure. Therefore, the following requirements should be considered in the selection of communication mode of electric vehicle charging pile (plug): First of all, the reliability of communication - the communication system should withstand the test of harsh environment and strong electromagnetic interference or noise interference for a long time, and keep the communication smooth. Secondly, construction cost - on the premise of meeting the reliability, comprehensively consider the construction cost and long-term use and maintenance cost. Then there is two-way communication - it can not only upload the amount of information, but also release the amount of control. Of course, there is also the data transmission rate of multi services - with the continuous growth of terminal traffic in the future, the communication from master station to sub station and from sub station to terminal has higher and higher requirements for the data transmission rate of multi services. Finally, the flexibility and scalability of communication - because the charging pile (plug) has the characteristics of many, wide and decentralized control points, it is required to adopt standard communication protocol. With the development of "all IP" network technology trend and the continuous growth of power operation business, it is necessary to consider the service bearing based on IP, and it is also required to be convenient for installation, construction, commissioning, operation and maintenance. Of course, many users will ask, how many specifications of cables are generally used for the installation of 3.5kw, 7KW and 11kw charging piles? Firstly, the 3.5kw charging pile generally uses 3 * 4 flat cable + pipe. If it is more than 30m, please use 3 * 6 flat cable; If 7KW pile is used, 3 * 6 flat cable shall be used; 5 * 6 flat cables are used for 11kw piles. The charging pile can be divided into single-phase and three-phase. No matter whether it is two-phase or single-phase, it should first be converted to the AC incoming line current. Install 3 * 4 square cables for 16a, 3 * 6 square cables for 32a, and 4 * 16 + 1 * 10mm cables for AC 40kW or DC 30kW. For details, please call the official website for consultation. For single-phase charging pile (AC charging pile), I = P / u For three-phase charging pile (DC charging pile), I = P / (U * 1.732) To learn more EV charging cable and EV cable,Please visit OMG's website : https://www.omgevcable.com/ |
