New energy vehicle connector market status
In the field of new energy automotive connectors, high pressure connector is an important device, mainly has the contact body, insulators, shell and accessories such as a few parts, because the new energy automobile work voltage range from traditional car 12 v to 400 v, the quality and precision of the connector put forward higher requirements, are used in the vehicle and charging infrastructure.
Distribution of global new energy automobile connector manufacturing enterprises, most of them Japanese companies, including sumitomo battery, Toyota, nissan, vector, etc., in terms of global connector market, the market concentration is higher, the basic was dominated by the United States, Japan and other countries, including a tyco accounted for more than 20%, the vehicle on the high voltage connector used to connect to the following systems: Power battery, high voltage wiring harness, switch, electric air conditioner, DCDC, charger, DC charging port, AC charging port, motor, inverter, etc.
High number of plug, heat resistance and current carrying capacity is the key factor development, new energy automobile connector manufacturing in terms of material selection should be equipped with the features of high temperature resistance material, on the seal, waterproof and shielding requirements is higher than traditional car connector, so the cost is higher, from the point of technology, electrical control, electrical connector of patent is more, There are few improvements in charging, battery connectors and grounding shielding. The operating voltage of pure electric vehicles and plug-in hybrid electric vehicles exceeds 300V, and the operating current is usually several hundred amperes. High-voltage cables provide a guarantee for the reliability and safety of electric vehicles.
Different from traditional car 12 v voltage, high voltage cable need to be considered to prevent overheating or burning, shielding performance, waterproof and dustproof, and electromagnetic compatibility, the vehicle electrical system in the practical use, high voltage cable produce magnetic interference will affect the car the integrity and accuracy of the data transmission of signal lines, seriously will affect the safety of the vehicle, High voltage cables need use the methods such as shielded wire to reduce magnetic disturbance, involves the battery pack voltage sampling and the temperature of cable for crimping process requirement is very high, you need to use the hydraulic equipment to replace the traditional process, in order to reduce fuel consumption, to replace the current widely used in aluminum copper to processing for high voltage cables, is a technology development trend.
