Intelligent charging pile cable selection standard

How to choose electric vehicle charging pile cable­ A charging pile is usually a high-power intermittent charging facility that can provide one or more charges for vehicles. Typically an unmanaged public facility. The charging station should have sufficient power and be able to charge multiple to dozens of battery packs at the same time. As needed, you can contact the pile foundation company to properly handle batteries of different specifications for charging.

Charging pile cable is an important power transmission method. As the electric vehicle charging pile cable for new energy vehicles and the power transmission bridge between the charging pile and new energy vehicles, its main application range can be used indoors or outdoors. Charging cables are divided into European standards, American (U.S.) standards and new national conductive charging interface standards as well as electric vehicle wire and cable specifications. Users/customers can select or customize specified power cables based on reference standards.

According to relevant standards/specifications: Currently, there are 5 types of conductive charging interface systems in the world:

IEC 62196-1,2. Mainly adopts the AC charging standards of European countries; IEC 62196-3 is mainly the definition standard of DC charging pile interface.

SAE J1772 is the earliest charging interface standard currently implemented. It is widely used in the United States and Japan. Its five-core AC charging interface is defined as a Class 1 interface in iec62196.

GB/T 20234,1,2,3 is the current national standard, which solves the problem of inconsistent charging interfaces in different regions and power grid companies in my country.

Most of the main members of chademo are from Japan. In order to promote the unification of Japan's fast charging specifications, Japanese car manufacturers mainly adopt chademo.

Specifications and characteristics of electric vehicle charging cable: mainly composed of conductor, insulation, shielding and sheath

1. Wire: multi-strand finely twisted oxygen-free copper wire, in line with relevant standards

2. Insulation: special mixed PVC insulation material

3. Inner sheath: Anti-oxidation tinned copper mesh braided shield, which can effectively prevent interference from various signals

4. Outer sheath and color: purj polyurethane material; gray, black, orange (can be customized according to customer requirements)

5. Rated voltage: New national standard AC and DC cable AC 450/750V; European standard AC 300/500V, 450/750V; DC 1000V; American standard 300V, 600V or 1000V

6. Test voltage: 2500V

7. Test temperature: resistant to high and low temperatures, -40~+105 (degrees Celsius)

8. Minimum bending radius: ≥ 6*outer diameter

The above is a reference for the specifications and standards of electric vehicle charging piles and wires and cables. To effectively transmit power, charging pile connecting devices must have high requirements for wires and cables.
