Under the general trend of electric vehicles gradually replacing traditional fuel vehicles, the annual global shipments of electric vehicles are also increasing at an alarming rate. At the same time, the demand for electric vehicle charging facilities is increasing. However, the failure rate of electric vehicle charging piles has been at a not low level. Among them, the damage of the charging cable accounts for a considerable proportion.
The UL Safety Testing Institute is the most authoritative in the United States and a large private institution engaged in safety testing and identification in the world. UL certification is a non-compulsory certification in the United States. 70% of the certification results are adopted by ANSI as American national standards, mainly for product safety performance testing and certification. The certification scope does not include the product's EMC (electromagnetic compatibility) characteristics, UL standards The focus of attention is to prevent fire and electric shock. The general standard for charging pile cables in North America is UL62 CSA C22.2 No.49. OMG AC charging cable has obtained UL certification. The cable is soft, has a good feel, and has a bending radius of less than 5D; oil resistance, acid and alkali resistance, water resistance, wear resistance, rolling resistance, crack resistance, UV resistance, color stability; good flame retardant performance; Bending more than 50,000 times; all materials comply with the latest environmental protection standards of RoHS&REACH.
The electric vehicle charging cable is the carrier connecting the electric vehicle and the charging pile, and its basic function is to transmit electrical energy. However, with the development of charging technology, to better complete charging, electric vehicles and charging piles need to communicate, and if necessary, automatic control. Therefore, the charging process imposes higher requirements on the charging cable. The charging cable not only needs to have the function of power transmission but also needs to transfer the status and information of the vehicle and power battery to the charging pile for real-time interaction. Under the necessary conditions, the charging Actions are controlled to complete the charging process safely and reliably.
