120kW charger usually refers to a charging device with a power of 120 kilowatts. This charger is mainly used for fast charging of electric vehicles. It can provide a large amount of electrical energy to electric vehicles in a short time, greatly shortening the charging time and improving the charging efficiency.

The basic parameters of 120kW charger are as follows:

Nominal voltage: 380V±15%

Current specification: 200 Amp

Protection level: IP54 (meets outdoor operation requirements)

Operating temperature: -25 to 55°C

Gun line length: 5M (may vary for different models)

Output voltage range: DC200-750V / DC150-500V (JIS)

Maximum output current: 200 Amp (may vary for different models)

Efficiency: ≥94%

Noise: ≤65dB

1. Charging capacity of 120kW charger

Theoretical charging capacity: Under ideal conditions (such as moderate battery temperature, stable power grid, etc.), a 120kW charger can theoretically charge 120kWh per hour. However, the actual charging capacity will be affected by many factors, such as vehicle battery capacity, charging strategy, battery status, charging equipment performance, and weather conditions.

Actual charging speed: Take the battery capacity of an electric vehicle model of about 100kWh as an example. Under ideal conditions, using a 120kW charger for fast charging, about 75kWh of electricity can be charged every 35 minutes, which is equivalent to about 75% of the total power of the vehicle. But please note that this is only a rough estimate, and the actual charging time may vary.

2. Factors affecting 120kW chargers

Vehicle factors: Different brands and models of electric vehicles have different battery capacities, battery management systems, and charging interfaces, which will affect the charging speed.

Environmental factors: The ambient temperature, humidity, and grid conditions during charging will also affect the charging speed. For example, in the cold winter, battery performance is affected by temperature, and the charging efficiency will be reduced accordingly.

Equipment factors: The performance, stability, and maintenance status of the charger will also affect the charging speed. High-quality chargers can usually provide more stable and faster charging services.

3. Application prospects of 120kW chargers

With the continuous expansion of the electric vehicle market and the continuous advancement of technology, the construction and upgrading of fast charging stations has become an important trend. As one of the more advanced charging devices on the market, the 120kW charger has broad application prospects. It can not only meet the needs of electric vehicle users for fast charging, but also promote the rapid development of the electric vehicle industry.

4. Precautions for 120kW chargers

When using a 120kW charger for charging, be sure to follow the operating instructions of the charging equipment to ensure the safety and stability of the charging process.

Pay attention to the indicator lights and display screens of the charging equipment to keep abreast of the charging status and abnormal conditions.

If you encounter any problems or abnormalities during charging, please stop charging immediately and contact professionals for processing.

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.
