Lithium Ion Battery 1MWH Lifepo4 Rechargeable Batteries for Energy Storage system ESS container
What is an Lifepo4?
Why choose Benergy Lifepo4 battery pack?
The Benergy 1MWH is a Lithium Iron Phosphate battery (LiFePO4) with a rated capacity of 1MWH. 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 1MWH 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 /86AH 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.
