1. Characteristics of charging pile lines
The line of the charging pile needs to meet the following characteristics:
1. High voltage: generally up to 700V or more, and even 1000V, which requires the insulation and voltage resistance of the wire to be extremely high.
2. High current: Depending on the usage scenario, some need to support 240V, 32A or even 63A current
3. Anti-impact: The charging pile is an outdoor equipment, and the line needs to withstand various conditions such as wind and rain, protection from the impact of trucks and cars, so the protection ability of the cable is extremely important.
4. Fire resistance: The flame resistance of the wire must be higher than that of ordinary cables.
2. Characteristics of ordinary cables
In contrast, the requirements of ordinary cables are relatively simple. Ordinary cables are usually used for the transmission of low voltage and small current, and the main features are:
1. Low voltage: Most cables can meet voltage levels below 600V.
2. Small current: Most cores can meet the current of less than 20A.
3. Round wire core: Ordinary cable wires usually use round wire cores, while charging pile wires require flat wire cores.
4. Softness: Ordinary cables need to have high softness to facilitate laying and connection in different occasions.
3. Comparison of charging pile lines and ordinary cables
The main difference between charging pile lines and ordinary cables is the required electrical and mechanical characteristics, and the electrical and mechanical characteristics of charging pile lines need to be higher than those of ordinary cables. In addition, charging pile cables also require higher requirements in the selection of materials and processing processes to ensure the quality and safety of the cables.
To sum up, the biggest difference between the charging pile wire and ordinary cable is in terms of electrical and mechanical characteristics, and the charging pile cable needs to meet the requirements of high voltage, high current, impact resistance, fire prevention, etc. When purchasing cables, users should choose different types of cables according to the specific scenario needs.

How long does the electronic wiring harness last?
Electronic wiring harnesses are widely used in our daily life and work, from mechanical equipment to electronic accessories, without wiring harnesses as carriers. The quality of the wiring harness can be seen from the service life of the wiring harness. Generally speaking, a good wiring harness can be used until the day the equipment is scrapped, of course, provided that the wiring harness is used correctly and cannot be illegally used or overloaded.
What factors affect the service life of the wiring harness?
The service life of the distribution cabinet wiring harness is constrained by a variety of factors. Ambient temperature is a key factor, and long-term high temperature (exceeding the temperature resistance level of wires) will accelerate the aging of the insulation layer and shorten the lifespan, such as 70 temperature-resistant wires in an 80 environment, the life may be shortened by 50%. Humidity is significantly affected, and the humid environment can easily lead to a decrease in wire insulation performance, causing short circuits, and wiring harnesses used in coastal areas or basements are more susceptible. In terms of mechanical stress, frequent vibration and bending will cause fatigue and breakage of the wire core, and if the bending radius is too small or not firmly fixed during installation, it will accelerate the damage of the wire harness. Among the electrical factors, long-term overload operation heats up the wire and accelerates the aging of the insulation layer; Excessive voltage fluctuations can break through the insulation. In addition, chemical corrosion (such as acid and alkali gases), electromagnetic interference, etc. will also affect the performance of the wiring harness, and comprehensive control of these factors can effectively extend the service life of the wiring harness.
The difference between new energy charging piles and electric vehicle charging wiring harnesses
New energy wiring harness manufacturers#The difference between new energy charging pile wiring harnesses and new energy electric vehicle charging wiring harnesses mainly lies in their use and technical requirements: Different uses: New energy charging pile wiring harness: The power transmission wiring harness used to connect the charging pile and the power grid, mainly responsible for transmitting the electrical energy of the power grid to the charging pile. The installation environment of this wiring harness is usually relatively fixed, mainly used in public charging facilities or home charging piles. New energy electric vehicle charging wiring harness: The wiring harness used to connect electric vehicles to charging piles, directly used to charge electric vehicles. It requires high flexibility and durability to be plugged and unplugged and moved frequently. Different technical requirements: Charging pile wiring harness: Because it is mainly used in fixed positions, it requires durability, high temperature resistance, UV resistance, and waterproof characteristics, and can adapt to long-term outdoor or indoor installation conditions. In addition, it also needs to have strong electromagnetic shielding and power transmission capabilities. Electric vehicle charging wiring harness: It pays more attention to the flexibility, bending resistance, and high safety of the cable, especially when the plugging and unplugging frequency is high. At the same time, cables also need to have wear resistance, aging resistance, and strong weather resistance. Structural differences: Charging pile wiring harnesses are usually thicker and longer, with higher current load capacity to ensure a stable supply of power to the charging pile. The length of the wiring harness is generally designed according to the distance between the vehicle and the charging pile, and has the ability to adapt to a variety of interfaces.
In-depth analysis of the six core components of the charging pile
The charging module, as the "heart" of the charging pile, not only accounts for about 50% of the hardware cost of the charging pile, but also the most critical and core component of the entire charging pile system. Hardware costs usually account for 90% of the total cost of charging piles, and the importance of charging modules is self-evident.
The car wiring harness reaches an astonishing 5KM, can't it be optimized?
In the seemingly compact space of the car, it is amazing that several kilometers of wiring harnesses are accommodated. For example, a family car is only 5 meters long and about 1.5 meters wide, but its wiring harness can be up to 5 kilometers long, and it can circle the car 384 times. So, why are automotive wiring harnesses so long? Automotive wiring harnesses play a key role in the "nerves and blood vessels" of the car. Like the nerves and blood vessels in the human body that connect the heart to the limbs, it is responsible for transmitting information and energy between various parts of the car. When the car is running, every functional command issued by the owner relies on the wiring harness to convey. Take the engine compartment of a fuel vehicle as an example, there are 5 to 8 meters long wiring harnesses distributed in it. As the "heart" of the car, the engine needs a wiring harness to supply power and transmit signals, which inevitably leads to an increase in the length of the wiring harness. In addition, the increasing abundance of automobile functions is also an important reason for the longer wiring harness. With the development of science and technology, cars are no longer just simple means of transportation, but a combination of comfort, safety, entertainment and other functions. Various advanced electronic devices, such as in-car navigation, reversing images, automatic parking systems, airbag control systems, and in-vehicle multimedia systems, are constantly being installed on cars. Each new addition means that more wires are needed to connect, resulting in longer and longer wiring harnesses. In addition, the complex structure of the car also has an impact on the length of the wiring harness. In order to ensure the accuracy and stability of signal transmission, the wiring harness needs to meandering between different parts, which undoubtedly increases the total length of the wiring harness. However, too long a wiring harness is not without its drawbacks. It not only increases the manufacturing cost of the car, but also occupies valuable space in the car, affecting the layout and design of the car. Moreover, too long wiring harnesses will also increase the probability of failure, and once there is a problem with the wiring harness, it is difficult to troubleshoot and repair. Today, the wiring harness revolution in the automotive industry has quietly emerged. With the acceleration of the development trend of automobile electrification and intelligence, the industry is actively exploring ways to reduce the length of wiring harnesses. For example, wireless communication technology is used to replace some wired connections, and the wiring harness layout is more reasonable and efficient by optimizing the automotive electronic architecture. This series of changes is expected to solve many problems caused by too long wiring harnesses and promote the automotive industry to a new stage of development.
