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/ |

What are the common causes of cable aging? The most direct cause of wire and cable aging failure is insulation breakdown and breakdown. Many factors can reduce the sensitivity of insulation. According to the actual operation experience, it can be summarized into the following situations. 1) Reasons for cable aging: external force damage. From the analysis of the operation situation in recent years, especially in Haipudong, where the economy is developing rapidly, a considerable number of cable faults are now caused by mechanical damage. For example: when the cable is laid and installed, the construction is not standardized, which is easy to cause mechanical damage; when the civil construction is carried out on the directly buried cable, it is also easy to damage the wiring. l Sometimes if the damage is not serious, it will take months or even years for the damaged part to completely decompose and cause a failure. Sometimes serious damage may lead to short circuit failure, which directly affects the power plant and the safe production of power plant. 2) Reasons for cable aging: The insulation is damp. This is also common and usually occurs at cable joints in direct burial or drains. For example, substandard cable splices and prefabricated splices in wet climates can allow water or steam to enter the splices. Over time, water branches will form under the action of the electric field, gradually destroying the insulation strength of the cable and causing failure. 3) Reasons for cable aging: chemical corrosion. Cables buried directly in areas with acid and alkali effects tend to corrode the armor, lead or outer sheath of the cable. The protective layer is subjected to chemical corrosion or electrolytic corrosion for a long time, which makes the protective layer fail and the insulation is reduced. Cable failure. Chemical: Corrosion of cell cables is quite severe 4) Reasons for cable aging: long-term overload operation. In overload operation, due to the thermal effect of the current, the conductor inevitably heats up when the load current passes through the cable. At the same time, the skin effect of the electric charge, the eddy current loss of the steel armor, and the dielectric loss will also generate additional heat, which will increase the temperature of the cable. During long-term overload operation, excessive temperature will accelerate insulation aging and damage the insulation. Especially in hot summer, the temperature rise of the cable often causes the weak insulation of the cable to be broken down first, so in summer, there are especially many cable failures. 5) Reasons for cable aging: cable connector failure. The cable joint is the weakest link in the cable line, and the cable joint failure caused by the direct failure of personnel (poor construction) often occurs. In the process of making cable joints, if the original mesh of the joint is not under pressure or insufficiently heated, the insulation of the cable head will be reduced, resulting in accidents. 6) Reasons for cable aging: environment and temperature. The external environment and heat source of the cable can also cause the cable temperature to be too high, insulation breakdown, and even explosion and fire.

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.
