It is estimated that the ratio of vehicles to piles in my country is 2.6:1, which is far lower than the 5 million charging piles proposed by the government in 2020, and the ratio of vehicles to piles is 1:1. According to the draft of the "New Energy Vehicle Industry Development Plan (2021-2035)" released by the Ministry of Industry and Information Technology, in the next ten years, there will be a gap of 63 million charging piles in my country, and it is expected to form a charging pile infrastructure construction market of 1.02 trillion yuan. EV has already risen as a national strategy, and the market is gradually expanding. As the main component of telex, EV cables are the carrier of power signal transmission and play a huge role. They are mainly divided into cable materials for charging piles/stations and high-voltage cable materials in vehicles. . The main requirements of EV new energy vehicle cables, the classification and standards of EV cables, the 8 materials commonly used in EV cables and the standards are wonderfully shared. 1. The main requirements of EV new energy vehicle cables EV cables are the main components of telex, and are mainly divided into cable materials for charging piles/stations and high-voltage cable materials in vehicles. Due to the high voltage, high current and harsh use environment, high safety specifications and use requirements are put forward for cable materials. 2. EV cable classification and standard EV cables are mainly divided into charging pile/station cable materials and in-vehicle high-voltage cables. 1. The charging pile cables meet the standards of CQC1103-1105, DECRAK175, EN50620, UL62, etc. There are differences in the materials and standards used for charging cables at home and abroad. At present, domestic charging cables are mainly based on CQC standards; EN50620 standards are widely used in Europe, mainly for high-end cars such as Mercedes-Benz and BMW. The materials used in cables It is generally TPU, which is soft and wear-resistant, but the price is relatively high; for the UL62 standard, Tesla in the United States uses it more. 2. The high-voltage lines in the car meet the standards of ISO6722, DECRAK179, QC/T1037-2016, CQC1122, etc. Since 2012, the high-voltage wires in the car have used the 6722 standard. At present, the car factory and the cable factory have formulated some of their own standards, such as QC/T1037-2016, CQC1122, etc. The 1122 standard is still a draft version. .
