With the increasing awareness of environmental protection, electric vehicle charging technology has become the focus and hotspot of the industry. Looking back on its development history, we can clearly see the transformation and leap from simple and rough to sophisticated and complex, from inefficient and clumsy to efficient and convenient. At this stage, electric vehicle charging technology is mainly divided into two categories: wired (AC/DC) and wireless charging, aiming to meet the diverse needs of different users. The standardization and unification of charging interfaces have undoubtedly greatly promoted the popularization of electric vehicles and the interconnection of charging facilities, bringing unprecedented convenience and efficiency to users. The improvement of charging control and management technology has ensured the safety and efficiency of the entire charging process, so that users can enjoy charging services without worrying about any safety hazards. However, the development of electric vehicle charging technology also faces three challenges: technical, economic, and social. On the technical level, we need to further improve charging speed and efficiency to meet users growing demand for charging speed; on the economic level, we need to find the best strategy to balance cost and pricing so that electric vehicle charging services can meet user needs and achieve sustainable development of enterprises; on the social level, we need to popularize charging facilities and coordinate grid resources to ensure that electric vehicle charging needs can be met. The prospects for electric vehicle charging technology are undoubtedly broad. Future technological innovations, such as solid-state batteries and wireless charging, will bring us more convenient and efficient charging solutions.
