Product Description
An 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.
Product Feature
Compared with DC charging pile (fast charging), AC charging pile has the following significant features:
1. Smaller power, flexible installation
The power of AC charging pile is generally smaller (3.3 kW and 7 kW), making installation flexible and adaptable to various scenes.
2. Slow charging speed
Limited by vehicle OBC power, it usually takes 6-8 hours for a full charge, ideal for overnight or long-term parking.
3. Lower cost
Manufacturing and installation costs are relatively low, making it suitable for residential and small commercial applications.
4. Safe and reliable
Equipped with protection against over-voltage, under-voltage, overload, short-circuit, and leakage.
5. Friendly human-computer interaction
Features like LCD color touch screens and multiple charging modes (quantitative, timed, intelligent) enhance user experience.
Frequently Asked Questions
What is an AC charging post?
An AC charging post, or slow charger, provides AC power to an electric vehicle's on-board charger (OBC), which then converts it to DC to charge the battery.
How long does it take to fully charge a vehicle?
Typically, it takes between 6 to 9 hours to fully charge a standard battery capacity electric vehicle, making it ideal for overnight use.
What are the different installation types available?
AC charging piles come in various forms including portable, wall-mounted (ideal for garages), and floor-mounted (landing type) for open parking spaces.
Are AC charging piles safe for home installation?
Yes, they are designed with multiple protection features such as IP65 water resistance, leakage protection, and safeguards against over-voltage and short-circuits.
Can I monitor my charging status?
Many models feature an LCD color touch screen that allows users to view charging time, current billing, and battery status in real time.
Is AC charging better for battery life?
Generally, frequent slow charging (AC) is considered gentler on the vehicle's battery compared to continuous high-power fast charging (DC).
