The copper flexible connector of new energy vehicles is a key component for connecting high-voltage batteries, inverters, air conditioning compressors, three-phase generators, and electric motors, used to achieve safe transmission of power and electrical energy. YIPU Metal provides high-voltage flexible copper connectors between high-voltage equipment of new energy vehicles. The following are some standards and requirements that new energy vehicle soft connectors need to meet.
1. Electromagnetic Compatibility (EMC): The soft copper connector design of new energy vehicles should ensure that the EMC of the components meets the standard requirements, in order to reduce electromagnetic interference and improve anti-interference ability. This includes the layout of the high-voltage system, shielding design, and anti-interference processing of the CAN communication network. The high-voltage wiring harness should be arranged along the vehicle body to optimize the loop of electromagnetic radiation of the entire vehicle, while using the vehicle body to form a closed shielding compartment.
2. Technical specifications: The technical specifications for high-voltage copper flexible connections of electric vehicles cover symbols, codes, terms and their definitions in the design process, design criteria, layout requirements, structural design requirements, material selection requirements, performance design, and other aspects.
3. Bending resistance: The pitch and diameter of the conductor strands in high-voltage copper flexible connectors for automobiles have a direct impact on their bending resistance. In general, the smaller the diameter of a single conductor, the shorter the pitch, which can improve the bending life of copper soft connections.
4. Safe transmission of high current and voltage: New energy vehicles usually use voltage platforms up to 300V~600V or even higher. Therefore, the basic requirement for high-voltage flexible copper connectors in automobiles is to safely transmit high current and voltage under electromagnetic interference protection systems.
5. Insulation and sheath materials: In order to ensure the insulation performance and durability of copper flexible connections, it is also very important to choose appropriate insulation and sheath materials. These materials need to be able to withstand conditions such as high temperature, wear, and chemical corrosion.
In summary, the design and manufacturing of copper flexible connectors for new energy vehicles need to follow a series of strict standards and specifications to ensure the stability of their performance and the safety of the vehicle. With the continuous development of the new energy vehicle industry, relevant technologies and standards are also constantly being updated and improved.
