How to choose electric vehicle charging station cables? Charging stations are usually high-power intermittent charging facilities that can provide one to multiple charges for vehicles. Usually an unmanaged public facility. The charging station should have sufficient power supply and be able to charge multiple to dozens of battery packs simultaneously. According to needs, you can contact the pile foundation enterprise to reasonably handle different specifications of batteries for charging.

Charging pile cables are an important means of power transmission. As a cable for electric vehicle charging stations and a power transmission bridge between charging stations and new energy vehicles, its main application range can be used indoors or outdoors. Charging cables are divided into European standards, American (US) standards, new national conductive charging interface standards, and electric vehicle wire and cable specifications. Users/customers can choose or customize specified power cables based on reference standards.

According to relevant standards/specifications, there are currently 5 types of conductive charging interface systems worldwide:

IEC 62196-1,2。 Mainly adopting the AC charging standards of European countries; IEC 62196-3 is mainly the definition standard for the interface of DC charging stations.

SAE J1772 is currently the earliest implemented charging interface standard. 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 that addresses the issue of inconsistent charging interfaces between different regions and power grid companies in China.

The main members of Chademo are mostly from Japan. In order to promote the standardization of fast charging standards in Japan, Japanese car manufacturers mainly adopt chademo.

Specification and characteristics of electric vehicle charging cables: mainly composed of conductors, insulation, shielding, and sheaths

1. Wire: Multi strand fine twisted oxygen free copper wire, in accordance with relevant standard

2. Insulation: Special mixed PVC insulation material

3. Inner sheath: antioxidant tinned copper mesh woven shield, which can effectively prevent interference from various signals

4. Outer sheath and color: Purj polyurethane material; Grey, black, orange (customizable according to customer requirements)

5. Rated voltage: New national standard AC 450/750V DC cable; European standards 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 stations and wires and cables. To effectively transmit power, charging station connectors must have high requirements for wires and cables. Users can contact Omega professional engineering personnel for inquiries based on the specifications and standards provided by their customers.
