Market Status of New Energy Vehicle Connectors

In the field of new energy vehicle connectors, high-voltage connectors are important devices, mainly composed of contacts, insulators, housings and accessories. The quality and accuracy of the device have put forward high requirements, which are used in the whole vehicle and charging facilities.

New energy vehicle connector manufacturers are distributed around the world, most of which are Japanese companies, including Sumitomo, Nissan, Yazaki, Toyota, etc. As far as the global connector market is concerned, the market concentration is relatively high, which is basically occupied by the United States, Japan and other countries. Among them, Tyco accounts for more than 20%. The high-voltage connectors on the vehicle are used to connect the following systems: power batteries, high-voltage wiring harnesses, switches, electric air conditioners, DCDC, chargers, DC charging ports, AC charging ports, motors, inverters device, etc.

High insertion and removal times, heat resistance and current carrying capacity are the key factors to be considered during development. In the production of new energy vehicle connectors, materials with high temperature resistance must be used, and the requirements for sealing, shielding and waterproofing are also higher than traditional ones. Automobile connectors are high, so the cost is also high. From the perspective of technical composition, there are many patents for electronic control and motor connectors, and there are fewer improvements to charging, battery connectors and grounding shielding. Pure electric vehicles and plug-in The working voltage of hybrid electric vehicles exceeds 300V, and the working current is usually several hundred amperes. The high-voltage cables provide a guarantee for the reliability and safety of electric vehicles.

Different from the 12V voltage of traditional automobiles, high-voltage cables need to consider preventing overheating or burning, shielding performance, waterproof and dustproof, and electromagnetic compatibility with the electrical system of the vehicle. In actual use, the magnetic interference generated by high-voltage cables will affect the The integrity and accuracy of data transmission in automobile signal lines will affect the safety of the entire vehicle in severe cases. Therefore, high-voltage cables need to use shielded cables to reduce magnetic interference, which involves battery pack voltage acquisition and temperature acquisition. The cable has high requirements on the crimping process, and it is necessary to use hydraulic equipment to replace the traditional process. In order to reduce fuel consumption, it is also a technology development trend to use aluminum to replace the currently widely used copper to process high-voltage cables.
