Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to an AC / DC integrated high-efficiency charging pile for new energy vehicles. Background Art

[0002] Charging piles refer to charging devices that provide energy supplements for electric vehicles. Their functions are similar to those of gas pumps in gas stations. They can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They 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. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-machine interactive operation interface provided by the charging pile to perform corresponding charging operations and print cost data. The charging pile display can display data such as charging amount, cost, and charging time. The charging pile (plug) can realize time-based, electricity-metered, and amount-based charging, and can be used as a terminal for citizens to purchase electricity. At the same time, in order to improve the efficiency and practicality of public charging piles (plugs), the functions of multiple charging and charging electric bicycles will be gradually added in the future.
