7kW ev charger, as the name implies, refers to an electric vehicle charging device with a charging power of 7 kilowatts. This charger is usually used in homes or small charging stations to provide stable and safe charging services for electric vehicles.

7kW ev charger product basic parameters:

Power：7kW

Connectors：Single

Input Voltage: AC220V±15%

Output Current：32A

standard: GB/T 18487 20234, IEC 61851 2017, SAE J1772, etc.

1. Types and characteristics of 7kW ev chargers

AC slow charging: output AC power and charge the battery through the on-board charger. Limited by the power of the on-board charger, the charging speed is relatively slow. 7kW chargers are more common in the field of AC charging.

Installation method:

Column type: fixed on the ground or wall, suitable for fixed places such as homes or parking lots.

Portable: lightweight design, easy to carry, suitable for temporary charging or outdoor use.

Cooling method:

Forced air cooling: forced heat dissipation through fans and other equipment, suitable for chargers with high power and high heat dissipation requirements.

Natural air cooling: relying on natural air convection for heat dissipation, suitable for chargers with low power and low heat dissipation requirements.

2. Precautions for using 7kW ev chargers

Choose a suitable charging method: choose a suitable charging method according to the charging interface and charging requirements of the electric vehicle.

Ensure charging safety: During the charging process, pay attention to the operating status of the charger and the charging status of the electric vehicle to avoid abnormal situations.

Regular maintenance: Clean and inspect the charger regularly to ensure its normal operation.

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.
