The following is some introduction to the 7kW charging station:

As an important equipment in the field of electric vehicle charging, the 7kW charging station is providing stable and reliable charging services for the majority of electric vehicle owners with its unique advantages.

1. Basic definitions and features

1.1. Definition: 7kW refers to the rated power of the charging station, that is, the electrical energy that can be transmitted to the electric vehicle per unit time is 7 kilowatts. The size of the power directly affects the speed of charging. Compared with some low-power charging stations, the power of 7kW can replenish a considerable amount of electricity for electric vehicles in a relatively short time.

1.2. Features:

Convenient installation: The 7kW charging station is of moderate size and relatively simple installation, suitable for home and small commercial places.

1.2.1. Widely applicable: compatible with a variety of electric vehicle models to meet the charging needs of different car owners.

1.2.2. Safe and reliable: with multiple safety protection measures, such as over-temperature protection, leakage protection, etc., to ensure the safety and reliability of the charging process.

2. Working principle and input voltage

2.1. Working principle: The 7kW charging station safely transmits the AC power of the power grid to the battery of the electric vehicle for charging through a series of conversions and controls. Its working principle is similar to that of a large power adapter, which converts the 220V AC power of the city power into AC power suitable for charging the battery of the electric vehicle.

2.2. Input voltage: According to common charging standards, such as CHADEMO and CCS, the voltage at the input end of the 7kW charging station is usually between 220/240V. However, it should be noted that the voltage of the charging station has no direct relationship with its output power.

3. Precautions for use

When using a 7kW charging station, car owners should pay attention to the following matters:

3.1. Ensure the compatibility of the 7kW charging station with electric vehicles: When choosing a 7kW charging station, you should confirm whether it supports your electric vehicle model.

3.2. Regular inspection and maintenance: Regularly inspect and maintain the 7kW charging station to ensure its normal operation and safety and reliability.

3.3. Comply with the use regulations: Operate in accordance with the instructions and operating procedures of the 7kW charging station to avoid safety problems caused by improper use.

4. 7kW charging station project display

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.
