There are many types of charging piles, which are divided into floor-mounted charging piles and wall-mounted charging piles according to installation methods. According to the installation location, it is divided into public charging piles and special charging piles. According to the number of charging interfaces, it is divided into one single charging pile and one multi-charging pile to improve the efficiency and practicability of public charging piles. According to the charging method, it is divided into DC charging pile, AC charging pile and AC/DC. Charging pile design is a tedious process. First of all, designers need to carry out user research and market research in the early stage of designing charging piles, starting from existing products, understanding the positioning of existing products, clarifying consumer consumption trends, finding innovations and formulating design plans. Secondly, after selecting the appropriate design plan, a product prototype should be created, user tests should be conducted to evaluate the new product, and the user tests should be revised and the original plan should be gradually improved. After the charging pile is designed, it is also necessary to consider the production cost and whether the current process and technology can achieve mass production, and to ensure the landing of the designed products, so as to ensure the significance of the design. In the design process, we should also pay attention to details, comprehensively consider the problem, comprehensively consider and then formulate a reasonable plan. As a new energy product, the use safety of charging piles must be guaranteed. Designers consider industrial design and structural design, as well as users, materials, processes, production costs, and product competitiveness.
