ac charging station

AC charging stations refer to charging facilities that charge electric vehicles through AC power. The AC charging station directly supplies the alternating current from the power grid to the on-board charger of the electric vehicle. The on-board charger then converts the alternating current into direct current to charge the battery of the electric vehicle. In this process, the AC charging station mainly plays the role of power output, while the actual power conversion work is completed by the on-board charger.

The basic parameters of the 7kw AC charging station product are as follows:

Power: 7kw

Connectors: Single

Input Voltage: AC220V±15%

Output Current: 32A

standard: GB/T 18487 20234, IEC 61851 2017,SAE J1772, etc.

The following is a detailed introduction to AC charging stations:

1. Characteristics of AC charging stations

Low cost: The construction and maintenance costs of AC charging stations are relatively low, making them suitable for large-scale promotion. For home users, installing home AC charging piles can significantly reduce charging costs.

High efficiency: Although the charging speed of AC charging stations is slower than that of DC charging stations, its current and voltage are relatively stable, which can better protect the battery and extend battery life. At the same time, the charging efficiency can reach more than 80%.

Easy maintenance: The installation of AC charging pile is relatively simple, just connect the charging cable to the charging port of the vehicle. In addition, AC charging piles are smaller and easier to maintain and upgrade.

High safety: AC charging piles have multiple safety protection functions such as overcurrent protection, overvoltage protection, short circuit protection, etc., which effectively avoid safety accidents caused by improper operation or equipment failure.

2. Application scenarios of AC charging stations

Home charging: AC charging piles are suitable for residential households and provide AC power for electric vehicles with on-board chargers. Car owners can park their electric vehicles in the parking space and connect them to the on-board charger for charging.

Commercial parking lots: Commercial parking lots can install AC charging piles to provide charging services for electric vehicles that come to park. Charging piles in this scenario generally have low power and slow charging speed, but they can meet the driver's charging needs in a short period of time such as shopping and dining.

Public charging stations: The government sets up public charging piles in public places, bus stations, highway service areas and other places to provide charging services for electric vehicles. The AC charging pile in this scenario has high power and can meet the charging needs of different types of electric vehicles.

Enterprises and institutions: Enterprises and institutions can install AC charging piles to provide charging services for the electric vehicles of employees and visitors.

Electric car rental companies: Electric car rental companies can install AC charging piles at rental stores or pick-up points to ensure the charging needs of the rental vehicle during the rental period.

Charging pile operators: Charging pile operators can set up AC charging piles in urban public areas, shopping malls, hotels and other places to provide convenient charging services for electric vehicle users.

3. AC charging station project case

Q1: Are you trading company or manufacturer?

A: We are a professional electric car charger manufacturer and source factory.

Q2: what is the lead time?

A: Usually, 15-20 working days to produce.

Q3: Can we ask you to print our logo into chargers? Can the color of the plug and wire be customized according to our requirements?

A: Yes. We support OEM/ODM production.

Q4: How about your product quality? What should I do if something goes wrong?

A: First of all, we sell our products for many years, and we have a professional engineering team in this field. Moreover, our products have been strictly inspected and repeatedly tested before leaving the factory, and the good and good rate of the varieties has reached 99.98%. Finally, we have service providers in some areas, please contact us for more information

Q5: What is your quality control system?

A: Complete all incoming material inspection, process inspection, and final inspection; 30 test procedures will be done before the goods leave the factory, and charging test videos will be sent; products have CE, ROHS, FCC, UL, KC certification.

Q6: Can I install the EV charger by myself?

A: Yes, but we suggest the user contact a professional electrician for installation to avoid potential safety hazards.

Q7：Why my charging power is lower than the specification?e?

A: Because during the charging session, a few factors will influence the output. Here is some potential reason:

①The BMS(Battery management system) of the car controls the charging session.

②The Max allowed current was set and limited through your APP.

Q8: How much time is required to fully charge my car using this charger?

A: The charging speed is determined by three factors working in conjunction: the On Board Charging (OBC) System, the maximum current allowed by the charging cable, and the EVSE. As an illustration, if the EV's maximum allowed power is 30KW and the battery capacity is 60KWh, it would take approximately 2 hours to charge the battery fully.

Q9: What is dynamic load balancing and why do I need that?

A: Dynamic load balancing is a technique that distributes the electrical load across multiple charging stations based on real-time demand. This helps prevent the electrical grid's overload and ensures that each charging station receives appropriate power.

Dynamic load balancing technology can help distribute the available power among multiple EV chargers in real-time, optimizing available power and reducing the risk of overloading the grid. This can help prevent power outages and reduce the need for costly grid upgrades.

Additionally, dynamic load Balancing can help reduce charging times and improve the overall charging experience for EV drivers, making it a valuable feature for both residential and commercial charging applications.
