AC charging post, also known as a slow charger, is a device designed to provide charging services for electric vehicles. The AC charging post itself does not have a direct charging function; instead, it needs to be connected to an on-board charging machine (OBC) on the electric vehicle, which converts the AC power into DC power, and then charges the battery of the electric vehicle.

Due to the low power of OBCs, the charging speed of AC chargers is relatively slow. Generally speaking, it takes 6 to 9 hours or even longer to charge an electric vehicle (with a normal battery capacity). AC charging piles are simple in technology and structure, with relatively low installation costs and a variety of types to choose from, such as portable, wall-mounted and floor-mounted, etc., which are suitable for different scenarios.

• Smaller power, flexible installation: Common power of 7 kw, 11 kw and 22kw, adapted to various scenes.
• Slow charging speed: Usually takes 6-8 hours to be fully charged, ideal for overnight or long-term parking.
• Lower cost: Manufacturing and installation costs are relatively low for home and commercial use.
• Safe and reliable: Equipped with management systems to monitor current and prevent over-voltage, under-voltage, overload, and short-circuit.
• Friendly interaction: Features a large LCD color touch screen with multiple modes like timed and intelligent charging.

AC charging piles are widely used in residential areas, office buildings, and public places to meet the diverse needs of electric vehicle users:

• Home charging: Night-time charging for residential homes.
• Commercial car parks: Charging services for parking customers in malls and hotels.
• Public Charging Stations: Installed at bus stops and motorway service areas.
• Scenic spots: Facilitating EV charging for tourists to improve travel experience.
