A charging pile is a type of electric car charging station component. They can be fixed on the ground or wall and installed in public buildings, residential parking lots, or public charging stations. Charging piles can be used to charge various types of electric cars according to different voltage levels.
1.Charging pile refers to a charging device with a charging gun and a human-machine interface, which is simply an electrical device that can be charged, either in one piece or in a split type.
Indoor charging piles should have a protection level of at least IP32 or above, while outdoor charging piles need to have a protection level of at least IP54 to ensure the safety of human bodies and charging equipment in harsh environments with wind, rain, and the need for better insulation and lightning protection.
Vertical charging piles do not need to lean against a wall and are suitable for outdoor or residential parking spaces. In contrast, wall-mounted charging piles must be fixed by the wall and are suitable for indoor and underground parking spaces.
