The DC wallbox, especially the DC wallbox charger for electric vehicles, is a wall-mounted charging device that can be installed in a variety of locations, including residences, workplaces, retail locations and other public places. The following is a detailed introduction to the DC wall box:

I. Definition and Use

The DC wallbox is a charging device designed for electric vehicles. It is usually installed on the wall to provide DC fast charging services for electric vehicles. This device can support multiple electric vehicles connected in parallel, providing them with a fast and efficient charging experience.

II. Working Principle

The working principle of the DC wallbox is relatively complex, but it mainly includes the following key steps:

Separation element: reversibly connect and separate the DC wallbox to the AC power grid to ensure the safety and stability of the charging process.

Rectifier: rectify the three-phase AC voltage and convert it into DC voltage to charge the battery of the electric vehicle.

DC voltage converter: further convert and adjust the rectified DC voltage to meet the charging needs of the electric vehicle battery.

III. Main application areas

The DC wallbox is mainly used in the following areas:

Residential areas: provide residents with convenient electric vehicle charging services to meet family charging needs.

Workplace: provide employees with electric vehicle charging services for enterprises to enhance employee welfare and corporate image.

Public places: such as parking lots, service stations, etc., provide electric vehicle charging services to the public and promote the popularization and development of electric vehicles.

4. Product Features and Advantages

Efficient Charging: The DC wallbox adopts DC fast charging technology, which can greatly shorten the charging time of electric vehicles.

Safe and Reliable: The equipment has multiple safety protection measures, such as overcurrent protection, overvoltage protection, etc., to ensure the safety and stability of the charging process.

Easy to install: The DC wallbox adopts a wall-mounted design, which is convenient and flexible to install and can adapt to various installation environments.

Intelligent Management: Some DC wallboxes also have intelligent management functions, which can be remotely monitored and managed through mobile phone APP or cloud platform to improve charging efficiency and user experience.

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.
