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 and the price of AC charging piles is relatively more affordable, with the price of ordinary household models generally not being too high.
AC charging posts are more suitable for installation in car parks in residential areas, as the charging time is longer and suitable for night-time charging. In addition, some commercial car parks, office buildings and public places will also install AC charging piles to meet the charging needs of different users. Although the charging speed of AC charging station is relatively slow and it takes a long time to fully charge the battery of an electric vehicle, this does not affect its advantages in home charging and long-time parking charging scenarios.
AC charging piles are widely used in homes, offices, public parking lots, urban roads and other places, and can provide convenient and fast charging services for electric vehicles.
- Home charging: For residential use with on-board chargers.
- Commercial car parks: Provides charging for parked customer vehicles.
- Public Charging Stations: Installed in bus stops and motorway service areas.
- Scenic spots: Improves traveling experience for EV-driving tourists.

Frequently Asked Questions
1. What is an AC charging post?
It is a slow charger that provides AC power to an electric vehicle's on-board charger (OBC), which then converts it to DC to charge the battery.
2. How long does it take to fully charge an EV?
Typically, it takes 6 to 9 hours or longer depending on the battery capacity and the power of the on-board charger.
3. Can I install an AC charging pile at home?
Yes, AC charging piles are very suitable for home use, including wall-mounted and portable models, because of their flexible installation and lower cost.
4. What are the safety features included?
They include protection against over-voltage, under-voltage, overload, short-circuit, and leakage, with an IP65 protection level for durability.
5. What is the main difference between AC and DC chargers?
AC chargers are slower and more affordable, making them ideal for long-duration parking (like home or work), while DC chargers provide faster charging but at a higher cost.
6. Are these chargers compatible with all electric vehicles?
Yes, as long as the electric vehicle is equipped with an on-board charger (OBC) that can receive AC power, it can use an AC charging post.
