Application Scenario

5G base station energy storage, battery composition capacity, emergency power supply and equipment aging

V2L, Vehicle to Load, is an electric vehicle with two-way charging and discharging equipment, which can be used as a mobile power station to supply power to a 220Vac AC load, which is equivalent to a mobile power bank. The AC/DC power supply realizes the bidirectional conversion of AC and DC; DCDC adopts high-frequency isolation bidirectional conversion technology, that is, soft switching resonance technology, which has high efficiency, and the converter energy flows in both directions, and the charge and discharge are automatically converted. The two-way charging and discharging equipment is widely used in many fields such as 5G base station energy storage, battery composition capacity, emergency power supply and equipment aging, and is the first choice for industries that require two-way flow of energy.

 

Features

1. Safer and more reliable, more flexible to choose

Full high-frequency isolation design to ensure the safety between the battery and the grid/load;

Full digital control of internal module DSP+CPLD, multi-level software and hardware over-current, over-voltage, over-temperature protection, safe and reliable;

Strong grid adaptability.

2. Higher efficiency

Compared with the traditional two-way power supply scheme, the core module saves the power frequency transformer, and the high frequency isolation efficiency is higher, as high as more than 95%;

The core module DC/DC adopts soft-switching resonance technology, and the highest efficiency reaches 98%.

3. More intelligent and friendly

Support on-grid and off-grid two working modes, namely V2G, V2L and other applications;

It can be configured as energy storage for emergency use, suitable for staged and important power supply scenarios such as the G20 summit, Boao Forum, and college entrance examinations.

4. Smaller size

Compared with the traditional two-way power supply scheme, the high-frequency isolation saves the power frequency transformer and is smaller in size.

5. More flexible configuration and more convenient power selection

Different forms of energy storage or battery formation systems can be flexibly designed according to customer needs.

6. Wide voltage range

Wide grid voltage range and 50/60Hz voltage frequency adaptive capability;

Covering multiple battery voltage levels of passenger cars (10V~100Vdc), the battery voltage range is wide, which is very suitable for the cascade application of automotive decommissioned power batteries.

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.
