The European research project NEXTBMS coordinated by the AIT Austrian Institute of Technology (long title: NEXT-generation physics and data-based Battery Management Systems for optimized battery utilization) aims to develop an advanced battery management system (BMS) on the basis of fundamental knowledge and experience with the physico-chemical processes of lithium-ion batteries.
[pdf] Return, the European leader in renewable energy storage services, continues to push the boundaries of clean energy innovation with Antares, a new 100 MW / 200 MWh battery energy storage system (BESS) in Waddinxveen. Antares is the second largest storage project in the Netherlands.

The Energy density of a battery is generally expressed in two ways, in the form of gravimetric energy density and as volumetric energy density. The gravimetric energy densityorthe specific energy of a battery is a measure of how much energy a battery contains in comparison to its weight, and is typically expressed in. .
Power density is normally mentioned in the units of Watts/L or Watts/Kg and is not to be confused withEnergy density, which is expressed as Wh/L or Wh/Kg.. .
Cost is an important factor in choosing a battery. In the table below is presented the cost per Watt-hour, Specific Energy i.e. Watt-hours per kg and the Energy. .
The below battery comparison chart illustrates the volumetric (i.e. energy density) and specific energy densities showing smaller sizes and lighter weight cells.. The gravimetric energy density or the specific energy of a battery is a measure of how much energy a battery contains in comparison to its weight, and is typically expressed in Watt-hours/kilogram (W-hr/kg).
