DC charging pile design is the first work in Newplan in 16 years. I would like to express my gratitude to the director and colleagues who helped me at the beginning (Sichuan elder brother who has always helped me). This work is an actual design project. I just know less about the material process and limited control and prediction of actual equipment. Therefore, this charging pile is relatively difficult to realize and process, but there is still some innovative and breakthrough self-feeling of the product. I mainly want to express the equipment sense and fashionable and light characteristics of the product, thus breaking through the heavy feeling of traditional equipment.
