Energy Storage System Provides Peak Shaving with an AC Power Conversion System PCS

Up to 1MWh 500V~800V Battery

Energy Storage System

For Peak Shaving Applications

3 Year Factory Warranty

Peak Shaving is becoming more and more popular as a means of conserving energy. This Energy Storage System is charged off the utility grid in off peak hours at very low electrical cost and then discharged during peak periods to dramatically reduce demand charges.

Peak Shaving works because you’re providing energy that doesn’t get billed by the power company. You’re not reducing usage; you’re altering the source of the energy. Here are 3 ways you can achieve Peak Shaving:

1.   Use an alternative localized power source during peak times of day.

2.   Improve your energy efficiency.

3.   Utilize solar energy battery storage.

The 1MWh Storage System makes use of a localized power source by the use of a Battery Pack, a Battery Management System (BMS), and an AC Power Conversion System (PCS).

Ask us about the components of a Power Storage System because we can tailor-make a Peak Shaving System in any Kilowatt range above 250 kW per module.

Simple and Reliable Battery Management System

Simple BMS

Battery Management System

For Lithium LiFePO4 Battery Packs in Series

We are excited to announce our brand new Battery Management System (BMS) called the Simple Lithium BMS. We got a large shipment in to our office of many sizes and voltages. The 12V 100A 4S BMS is pictured above with a wiring diagram to show connections.

In addition to the BMS System with a link above we also provide a BMS for Solar BMS applications. They come in 12V or 48V voltages and are for 4 or 16 Lithium LiFePO4 Battery Packs in series.

The top quality (A-level) Protective Circuit Board IC has Power Balancing Function and the circuit is simple and reliable.

We know that the Simple Lithium Ion BMS will replace many existing Battery Management Systems because of reasonable price and easy operation. Compare the Simple BMS to any other BMS and see for yourself why we love this new product!

Frequently Asked Questions about the BMS/PCB

1, Which current PCB should I use?

Take a 13S 48V pack as an example: Which PCB you should use depends on the power of your motor or the current limitation of your controller. Below 350W, you can use 16A. Below 500W, you can use 18A, Below 800W, you can use 35A, Below 1KW, you can use 60A. Above 1200W, the same. If you are not sure, please contact us.

2, Can I use a bigger size of PCB than is indicated?

Suppose you need 60A PCB but you chose 80A, that will work.

80A allows for a higher current. A bit higher price is the only drawback.

But if you choose 50A, it will be too small. So you can use a higher spec but not a lower one than it should be.

3, What kind of charger should I choose?

A Lithium Battery must be charged by a Lithium Battery Charger. You can’t charge it with a lead acid battery charger because the lead acid battery charger might damage the MOS pipe of the PCB.

4, if I have a PCB, do I need any balancers?

Yes if you add QNBBM balancers, that will be perfect. 

The Main function of the PCB is to prevent batteries from over-charging over-discharging, over-heating etc.

With balancers added, the batteries lifespan will be longer and the capacity will get fully used.

5, How do I judge if my PCB is broken or not?

If you’d like to judge if the PCB is fine or not, please use a multi-meter and see if the voltage of each cell is close to one other or not. When the voltage difference is 1V, the battery will have this kind of performance: the driving distance will be short, it will be cut off when started, the charging time will be very short. Under such a situation, a battery is defective. When the PCB is broken, the battery can’t be discharged. When you measure the battery voltage, it will be normal.
