The 40KW ev charger is a high-power charging equipment specially designed for electric vehicles. It can greatly shorten the charging time of electric vehicles and improve charging efficiency. The following is some introduction to 40KW ev chargers:

1. Main features

High power output: 40KW power output means that electric vehicles can be fully charged in less time. Compared with low-power chargers, 40KW chargers significantly reduce the time required for charging and improve charging efficiency.

Intelligent management: The 40KW ev charger is equipped with an intelligent charging management system. These systems can automatically adjust charging power and current based on the battery capacity and charging needs of electric vehicles to ensure that the charging process is both fast and safe.

Efficient heat dissipation: High-power charging will generate a lot of heat, so 40KW ev chargers usually adopt advanced heat dissipation technology to ensure that the charger can maintain stable performance when working for a long time.

Multiple protection: In order to ensure the safety and reliability of the charging process, 40KW ev chargers are usually equipped with multiple protection mechanisms, such as overvoltage protection, overcurrent protection, short circuit protection, etc. These protection mechanisms can monitor the status of the charger in real time during the charging process, and take immediate measures to protect it once an abnormality is discovered.

2. Market application

Public Charging Stations: The 40KW ev charger is ideal for installation at public charging stations to meet the fast charging needs of a large number of electric vehicle owners. At public charging stations, car owners can easily find and use these chargers to quickly recharge their electric vehicles.

Home charging: Although 40KW ev chargers are usually used in public charging stations, for some home users, if the residence has corresponding power conditions and has an electric vehicle with high range requirements, then a 40KW ev charger is installed. Also a good choice. However, it should be noted that when home users install and use 40KW ev chargers, they need to ensure that the residential power system and grid can withstand such high power output.

3. Precautions for use

Matching check: Before using the 40KW ev charger, car owners need to ensure that the charger matches the battery capacity and voltage of the electric vehicle. Otherwise, it may cause poor charging or damage the charger and battery.

Correct operation: When charging, car owners need to follow the correct operating steps.

Safe environment: When the charger is working, it is strictly prohibited to cover the charger shell to ensure that the charger and electric vehicle battery work in a well-ventilated environment.

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.
