A wall box charging station, especially a wall boxcharger, is a charging device installed on a wall or column, designed to provide charging services for electric vehicles or electric equipment. The following is a detailed analysis of the wall box charging station:

1. Function

The wall box charging station has a variety of functions, such as swiping cards in public places, metering, printing, uploading signals, etc. It can also be equipped with an intelligent control system, which can be operated through a touch screen, mobile APP or RFID card to achieve functions such as remote monitoring, fault diagnosis and data statistics.

2. Applicable scenarios

Home charging: For families with electric vehicles, installing a wall box charging station in a private garage or community parking space is the most direct and convenient way to charge.

Community public charging: For residents who do not have private garages or parking spaces, the community can set up wall box charging stations in public areas for shared use by owners.

Employee charging: Install wall box charging stations in office building parking lots to facilitate employees to charge electric vehicles during work.

Customer service: Commercial areas such as shopping malls, supermarkets, restaurants, etc. can install wall box charging stations in their parking lots to provide customers with convenient charging services.

Municipal services: The government can set up wall box charging stations in public places such as parks, libraries, museums, etc. to provide public charging services to citizens.

Tourist attractions: Installing wall box charging stations in tourist attractions can meet the charging needs of tourists during their tours.

Enterprise self-use: Enterprises in industrial parks can install wall box charging stations for employees or logistics vehicles to meet their charging needs in daily operations.

3. Advantages and Features

Space saving: The wall box charging station is installed on the wall and does not occupy the ground space. It is suitable for use in places with limited space such as parking lots, garages, and commercial areas.

Easy installation: Since it is directly fixed on the wall, the installation process is relatively simple and quick, which can save installation time and cost.

Wide applicability: It supports multiple charging interface standards and is suitable for electric vehicles of different brands and models, with strong compatibility.

Strong environmental adaptability: It has a high protection level and can work normally under harsh environmental conditions, such as high temperature, low temperature, humidity, etc.

4. Precautions

Installation location: It is necessary to choose a suitable installation location to ensure that the connection between the charging station and the vehicle is convenient and safe.

Wire laying: Since the wall box charging station needs to drill holes and lay wires, it is necessary to ensure the quality and safety of the wires to avoid problems such as short circuit, aging, and shedding of the wires.

Use and maintenance: The user needs to use the charging pile correctly according to the instructions, and conduct regular inspections and maintenance to ensure its normal operation.

5. Project Cases

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.
