The charging pile refers to the charging device that provides energy supplement for electric vehicles. Its function is similar to the fuel dispenser in the gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. The charging pile generally provides two charging modes: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interactive operation interface provided by the charging pile to carry out the corresponding charging operation and cost data printing. The charging pile display screen can display the charging amount, cost, charging time and other data. Model making software: 3ds Max 2014 Rendering software: vray3.60.03 for 3dmax2014
