DC Bus Battery Storage

DC Bus Battery Storage

Features

GreenBattery is a safe, highly efficient and modular energy storage system with relatively low weight and small volume. Each GreenBattery has a capacity of 80kWh and a nominal DC Bus voltage of 832VDC. Multiple GreenBatteries can be mounted in parallel to realize energy storage systems ranging from 80kWh to 4MWh. Each GreenBattery includes a Master BMS and DC Bus contactor. Various safety devices are built into GreenBattery. In the unlikely event of a battery cell explosion, it does not propagate to other cells (no thermal runaway) and it is contained inside the
battery housing in order to guarantee a safe energy storage system without pollution to the surrounding environment of GreenBattery.   

 

 

GreenBattery Electric Energy Storage

GreenBattery is a highly efficient and modular energy storage system with relatively low weight and small volume. Each GreenBattery has a capacity of 80kWh and a nominal DC Bus voltage of 832VDC. Multiple GreenBatteries can be mounted in parallel to realize energy storage systems ranging from 80kWh to 4MWh. Each GreenBattery is built up with 8 individual batteries and a Master BMS. The Master BMS contains a 5”TFT touch operator panel with controller and includes a DC Bus contactor and heat exchanger. All external connections are made available on the Master BMS.

Various safety devices are built-in for preventing thermal runaway. In the unlikely event of a battery cell explosion, it is contained inside the battery housing in order to guarantee a safe energy storage system without pollution to the surrounding
environment of GreenBattery. Each battery is totally enclosed and GreenBattery includes a pressure based safety release which should be vented to the outside environment.


GreenBattery is liquid cooled by seawater or water/ glycol and a built-in controller regulates battery temperature in between 20 and 40 degrC. GreenBattery can be placed in any room with the ambient temperature up to 55 degrC. GreenBattery does not heat-up the room. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Battery Management

The batteries are built up with Lithium NCA technology battery cells which have considerable lower weight and higher power density when compared to other battery chemistries. In addition the applied Panasonic battery cells have a long track record and are widely used in electric cars. Each
battery has 12 temperature measurements and a built-in BMS (Battery Management System) which communicates with the Main BMS. The Main BMS 5”TFT touch operator panel contains redundant Ethernet ports for communication to GreenInverters for charging/discharging and GreenEMS for energy management. GreenBattery fulfils the latest class requirements and a risk based assessment is made for every project and approved by class. GreenBattery is supplied in two different mechanical lay-outs: a vertical one for space  saving and a horizontal one with a lower center of gravity.
