Designers through market adjustment to analyze, combined with design requirements through appearance design, structural design and design of continuous innovation and design. This pillar type DC charging pile design integrates power conversion and charging control, and realizes the integration and intelligence of charging and controlling electric vehicle charging. It has the functions of management, inquiry, display, code scanning payment and background communication, and through communication with the vehicle management system (BMS), according to the real-time data provided by the BMS, it dynamically adjusts the charging current or voltage parameters, performs corresponding actions, and automatically completes the charging process, realizes the intelligent control of the entire charging process, and has the function of fully charging the electric vehicle battery safely. At the same time, its safety protection function is perfect, with emergency stop function, overload protection, short circuit protection, leakage protection, lightning protection, overheat protection, insulation protection, battery reverse connection, battery overvoltage, battery failure and other protection functions, and its performance is stable and reliable. In terms of appearance design, the vertical column type DC charging pile design adopts an integrated whole machine structure, with simple lines and beautiful modeling technology; it is made of high-quality aluminum alloy material, with exquisite surface treatment process, IP grade in line with national industry standards, corrosion resistance, rain prevention, sun protection, sturdy and durable, and can be applied to harsh environments to meet the needs of outdoor installation. The height of the column type charging pile is moderate, the height is set at 1.2 m-1.5m, the operation interface is located on the top of the body, and the LCD touch screen control adopts inclined plane design. The overall design is novel and conforms to people's usage habits. Charging is simple and comfortable, dual charging interface output, and charging methods are diversified to meet the charging needs of different vehicles. The front of the charging pile is marked with clear and eye-catching usage procedures and precautions, and.
