Description

technical field [0001] The invention relates to the field of charging piles, in particular to a wireless and wired charging device, which belongs to the technical field of charging piles. Background technique [0002] The function of the charging equipment in the charging station is similar to that of the fuel dispenser in the gas station. It can be fixed on the ground or the wall, installed in the parking lot of public buildings and residential areas or in the charging station, and can charge various types of electric vehicles according to different voltage levels. The charging methods of electric vehicles in today's market are mainly charging piles for ordinary charging, charging stations for fast charging and changing stations for replaceable batteries. However, there is a disadvantage of these three charging methods, which is the common standard of wired connection. Ordinary charging methods take a long time to charge and require a lot of waiting time for charging, whic...
