Requirements and standards for charging cables for electric vehicles

At present, the application of charging cables is generally increasing on the road. The charging of new energy electric vehicles has increased significantly, of course, including electric buses and transport vehicles.

New energy electric vehicles are becoming more and more widespread. As the connectors for charging piles and electric piles that provide power, electric piles are divided into wall-mounted AC and fast-charging DC. One is a home AC charging pile, such as a small charging device given when buying a car, and a wall-mounted charging pile in an underground parking garage. The battery is generally fully charged in more than 8 hours. The other is a public DC charging pile, which is mostly used in parking lots and highway service stations. This can also be understood as the fast charging piles often mentioned by car owners. Under normal circumstances, the time required for a fast charging pile to fully charge various pure electric models on the market is within 1h-2h. Users can purchase and install according to their needs.

Of course, the production quality requirements for cables and other connectors are important. Whether it is a charging pile or a charging gun, the region is particularly strict with this protection performance, and has strict manufacturing standards for charging components and interfaces, requiring that the protection level of AC and DC charging gun series products must reach IP55. Of course, most models on the market have reached the protection level of IP*6-IP*7. The charging gun interface is waterproof and dustproof, which has become an industry standard. The seemingly cheap charging pile equipment outdoors has protection capabilities comparable to high-tech products that have long been comparable. This allows the public to use it more standardized, safer and more worry-free.

Cable adaptation introduction: To provide electric vehicles with fast and effective power, in addition to a good charging gun interface, there must also be cables with good quality and reputation. The two product standards are matched, so that the charging effect can be achieved. The charging cable is used to connect the electric vehicle charging device with the charging infrastructure, so as to transmit power to the electric vehicle, and is equipped with a certain number of signal lines, control lines, power auxiliary lines, etc. to ensure that the entire charging process is accurate and the operation is safe and correct. In addition, the charging cable requires high and low temperature resistance, oil resistance, acid and alkali resistance, water resistance, wear resistance, cracking resistance and other cable requirements.
