The cost of electric vehicle charging connectors can be reduced from the following aspects.

In terms of technology research and development and design optimization, optimize the connector structure, reduce unnecessary parts and complex designs, make the structure simpler while ensuring performance, and reduce material and manufacturing costs. Improve integration, integrate charging control circuits, communication modules, etc. into the connector, realize integrated design, and reduce external connection lines and components. Apply new materials, such as replacing some traditional metal materials with high-strength aluminum alloys or composite materials, and develop new insulating materials.

In the production and manufacturing process, improve production efficiency, introduce advanced production equipment and automated production lines, reduce manual operations, and reduce costs and production cycles. Optimize production processes, improve yield rates, and reduce scrap rates and production costs. Strengthen supply chain management, cooperate with high-quality suppliers, and obtain preferential prices and stable supply.

Standardization and generalization are very important, promote the unification of industry standards, improve compatibility between different brands and models, and reduce R&D, manufacturing and inventory costs. Standardized design and management should also be carried out within the enterprise to increase the reuse rate of parts.

From the perspective of system architecture optimization, optimize the high-voltage system architecture of the whole vehicle, reasonably plan the location and connection method of the charging connector, and reduce the number of uses and the length of the high-voltage wiring harness. Collaborative design and optimization: let the charging connector work with the vehicle system in the early stage of vehicle design to avoid later cost increase.

In terms of after-sales maintenance and quality assurance, improve product reliability, strengthen quality control and reliability testing, and extend service life. Optimize after-sales maintenance services, establish a complete system, improve maintenance efficiency and service quality, and reduce after-sales maintenance costs.
