We all know about new energy electric vehicles in our daily life. In electric vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, and air conditioning power. Automobile harness is the main body of automobile circuit network and the carrier of automobile circuit. Automobile harness is the bridge and link of vehicle electrical components and the nervous system of vehicle power and signal transmission and distribution. The high-voltage harness can be configured according to different voltage levels, and the internal and external harnesses of electric vehicles can be connected. It mainly applies the signal distribution of the internal harness of the distribution box to transmit electric energy with high efficiency and quality and shield external signal interference. The high-voltage connection system consists of high-voltage harness and connector. DC / DC, water heating PTC charger, air heater, DC charging port, power motor, high-voltage harness, maintenance switch, inverter, power battery, high-voltage box, power air conditioner, AC charging port, etc. all need connectors; High voltage harness is the neural network of high voltage system of new energy vehicles, which is very important. It also mainly includes battery system, powertrain, high-voltage electric control system, charging system, high-voltage equipment and its harness system. The high-voltage line of electric vehicle is used to connect the charging port with the battery, the interior of the battery, the battery with the engine and other components, as well as the field of battery energy storage equipment, as the carrier of power transmission. Due to the harsh application environment in the vehicle, the high-voltage cable of electric vehicle has very high performance requirements. Application characteristics of cables for electric vehicles: small wiring space, high current and high voltage, many high and low temperature environments, poor heat dissipation, poor driving environment, salt fog and electromagnetic field, oil and chemicals, low smoke halogen-free flame retardant and other environmental and safety requirements. Application characteristics of electric vehicle cable: small wiring space, high current and high voltage, and all indicators meet the requirements of environmental protection and safety.

When it comes to the electric vehicle charging pile industry, the problem facing charging pile investors, operators and construction enterprises is how to get rid of the dilemma of "burning money" in the shortest possible time. For enterprises and operators, this war can become a "consumption war", in which the real realization problem is to "live" to the turning point of profit. In order to seize the charging pile market, relevant industry giants have made their own tricks. From power grid charging stations to energy deployment, from automobile manufacturers to charging pile operators, each process tends to the development of charging pile industry. Among them, the State Grid has built a highway fast charging network covering 176 cities. At the same time, it is also vigorously developing the energy storage system dominated by pumped storage to improve the flexible regulation capacity of the power grid. With the continuous improvement of the network coverage of charging piles, the value and potential of charging piles are increasingly reflected. Facing the huge market opportunities, industry players need to focus on policy, capital, technology, operation, service and business model to form a long-term development strategy. Charging piles cover the world. New energy vehicles will benefit the charging pile industry, attract more investors and find new opportunities for more enterprises. Finally, after years of research and application and continuous support of policies, the charging pile industry has gradually moved towards a new stage of mature and stable development. In the future, the charging pile will usher in new opportunities and role changes under the guidance of "new infrastructure"; Building a diversified and integrated professional solution integrated with the technology of the new era is an important development trend of the charging pile industry chain in the future. In the huge market space, the charging pile industry is still in the period of technological and policy change, with risks and opportunities coexisting, which is also faced and required to be solved in the future. This makes the industry develop effectively. Tips：To learn more EV charging cable and EV cable,Please visit OMG's website: https://www.omgevcable.com/ |

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/ |
