Customer Reviews
Hello Kevin, The battery pack is working extremly well and I'm pleasantly surprised by the power it supplies. I will buy more in the future.

—— Mr Daniel (USA)

About the order, I am very satisfied about quality (180AH Lifepo4) cells are very good! I used them into my new project for electro solar catamaran I made myself 2014/2015. It is very nice...very good! My Best

Lithium Ion Battery 2MWH Lifepo4 Rechargeable Batteries For ESS Container Solar System Peak Shaving Of Electric Power

 

What is an Lifepo4?

 

The lithium iron phosphate battery (LiFePO4 battery) or LFP battery (lithium ferrophosphate), is a type of lithium-ion battery using lithium iron phosphate (LiFePO4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. The energy density of LiFePO4 is lower than that of lithium cobalt oxide (LiCoO2), and also has a lower operating voltage. The main drawback of LiFePO4 is its low electrical conductivity. Therefore, all the LiFePO4 cathodes under consideration are actually LiFePO4.Because of low cost, low toxicity, well-defined performance, long-term stability, etc. LiFePO4 is finding a number of roles in energy storage,vehicle use, utility scale stationary applications, and backup power.LFP batteries are cobalt-free.

 

 

Why choose Benergy  Lifepo4 battery pack?

 

The Benergy 2MWH is a Lithium Iron Phosphate battery (LiFePO4) with a rated capacity of 2MWH. The unique combination of state-of-the art technology and smart software makes this lithium battery a robust, safe and easy to use energy storage solution. Compared to conventional lead-acid batteries, the Benergy 2MWH lithium battery offers an enormous weight and space saving. It is very efficient, has extremely high performances and is maintenance free.

 

 

System composition

 

Our company is responsible for the design of the whole energy storage system, and the scheme mainly includes:

* lithium iron phosphate battery: battery cluster is composed of Benergy 3.2v 280AH power battery in series and parallel.

* PCS converter: Power Conversion System (PCS), two-way energy flow, charging and discharging integrated design. The battery pack is connected to the ac bus through PCS to ensure the stable and reliable power supply of bus.

* BMS: the battery management system (BMS) is the bond between the battery and the user, mainly for rechargeable batteries, to improve the utilization of the battery and prevent overcharging and over discharge of the battery. Charging and discharging control of energy storage system and battery SOC information monitoring can be completed according to the instruction.

* EMS: Energy Management system (EMS), responsible for collecting BMS information, setting control strategy and adjusting converter output according to battery information, only support local monitoring

* Container: using one container for the energy storage system, the container is divided into two parts--battery and electrical equipment, need to install below items inside of container: the battery pack (and related control devices), dc combiner box, air conditioner, automatic fire extinguishing systems, lighting inside the box, converter, EMS control cabinet, etc.
