battery storage system

A battery storage system is a device or system that can store electrical energy and can be regarded as a large, mobile "power bank". It can not only provide power support when power demand is high or power grid power supply is unstable, but also store electrical energy for subsequent use when power supply is in excess. This system consists of multiple battery cells, which can store, release and monitor electrical energy through advanced battery management technology and intelligent control systems.

1. Application scenarios of battery storage systems

1.1. Industrial and commercial applications: In factories, shopping malls, data centers and other places, battery storage systems can be used as backup power or auxiliary power to ensure the continuity and stability of power supply.

1.2. Microgrids and smart grids: In microgrids and smart grids, battery storage systems can be used as important energy storage devices to achieve the dispatch and optimization of electrical energy and improve the reliability and flexibility of the power grid.

2. Advantages of battery storage systems

2.1. Improve energy utilization: By storing and releasing electrical energy, battery storage systems can balance power supply and demand and improve energy utilization.

2.2. Reduce electricity costs: Battery storage systems can help users reduce electricity costs by charging when electricity demand is low and discharging when it is high.

2.3. Enhance grid stability: Battery storage systems can serve as a "buffer" for the grid, providing regulatory support when electricity supply is insufficient or excessive, and enhancing grid stability.

2.4. Promote sustainable development: Combined with renewable energy, battery storage systems help promote the transformation of energy structure and promote sustainable development.

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.
