[0002] With the rapid development of the electric vehicle industry, the construction and operation of electric vehicle charging stations have become increasingly important. As a key component, the power module in the charging station directly affects the charging efficiency, safety and reliability. However, the existing power modules of electric vehicle charging stations have some shortcomings in design and structure. The existing power modules have certain difficulties in installation and maintenance. For example, the removal and replacement of parts requires a lot of time and effort, which is not conducive to rapid response and troubleshooting. In addition, with the continuous advancement of electric vehicle technology, the requirements for charging station power modules are also getting higher and higher. Higher power density and charging efficiency are required to shorten charging time and improve user experience.
