Exploring the energy bond between charging piles and electric vehicles

Product Overview: In the use of electric vehicles, the charging cable between the charging pile and the electric vehicle seems ordinary, but it actually plays a key role. It is the "energy bridge" to ensure the smooth replenishment of energy for electric vehicles. ​

Charging cables are mainly divided into AC charging cables and DC charging cables. AC charging cables are generally used in home slow charging scenarios, connecting single-phase or three-phase AC charging piles and electric vehicles, and contain live wires, neutral wires and ground wires. DC charging cables are used for public fast charging, connecting DC charging piles and electric vehicles. In addition to the positive and negative high-voltage DC wires and ground wires, there may also be communication wires and control wires in the cable. For common household 7kW charging piles, if the distance from the distribution box to the parking space does not exceed 55 meters, YJV36 square cables are generally used; and if the distance is 55-90 meters, YJV310 square cables must be used. ​

In terms of performance, its requirements are very strict. First of all, it must have excellent conductivity. You should know that when electric vehicles are charged, the current is large. For example, when DC fast charging is used, the current may be as high as several hundred amperes. This requires that the conductor material of the cable is excellent. At present, copper is mostly used because of its excellent conductivity and corrosion resistance. At the same time, insulation performance is also crucial. The insulating material must not only effectively isolate conductors of different voltage levels to prevent safety accidents such as electric shock, short circuit, overheating, but also have good heat resistance, flame retardancy, and anti-aging properties. In daily use, charging cables are often faced with outdoor environments, so they must also have characteristics such as UV resistance, waterproofness, wear resistance, and oil resistance to ensure long-term stable performance. For example, the sheaths of many charging cables are made of special rubber or plastic materials, which can cope with these complex environments well. ​

During use, charging cables may also fail. For example, poor contact between the plug and the socket may be caused by long-term plugging and unplugging, resulting in wear of the interface, or foreign matter entering. At this time, charging may be interrupted or charging speed may be slow. There is also an internal circuit break in the wire. External force pulling and excessive bending may cause the internal conductor to disconnect. In this case, the entire cable needs to be replaced. If the outer sheath of the charging cable is found to be damaged, even if it is only slightly damaged, it cannot be ignored, because this will reduce the insulation performance and bring safety hazards, and must be handled in time. ​

During daily use, we must also pay attention to the maintenance of the charging cable. When plugging and unplugging the charging gun, hold the gun body and do not pull the cable to avoid damaging the internal circuit. If it is used outdoors, try to avoid the cable being crushed by the vehicle or scratched by sharp objects. Check the appearance of the cable regularly to see if there are any abnormal conditions such as damage or bulging. Once a problem is found, contact a professional for repair or replacement in time.

Whether it is slow charging in the home garage or fast charging at a public charging station, our charging cable can be perfectly adapted. It has excellent wear and corrosion resistance, is not easily damaged by frequent plugging and unplugging, resists external erosion, and has a service life far exceeding similar products. It is your long-term trusted charging partner. ​Welcome to: https://www.omgevcable.com
