Energy storage battery shell design

What is a battery energy storage system (BESS)?

To address this challenge, battery energy storage systems (BESS) are considered to be one of the main technologies . Every traditional BESS is based on three main components: the power converter, the battery management system (BMS) and the assembly of cells required to create the battery-pack .

Why do we need battery energy storage systems?

Fluctuations in electricity generation due to the stochastic nature of solar and wind power, together with the need for higher efficiency in the electrical system, make the use of energy storage systems increasingly necessary. To address this challenge, battery energy storage systems (BESS) are considered to be one of the main technologies .

Why should a battery pack be modular?

This is because the reusability of the design and even the repair or replacement of cells becomes much more challenging in a battery-pack with a large number of cells. Modularity allows easily customizing the design for different voltage, power and energy levels.

Are big-size battery-packs a viable solution for Bess?

Creating big size battery-packs has been the traditional solution for BESSs. With the results obtained in this research, it is numerically demonstrated that new technological solutions towards more reliable modular BESSs are mandatory.

Are new technology solutions required for more reliable modular battery-packs?

With the results obtained in this research, it is numerically demonstrated that new technological solutions towards more reliable modular BESSs are mandatory. In parallel, this improvement may enable the incorporation of new control strategies and new replacement systems of damaged battery-packs.

Can a battery reliability analysis be replicated in AC Bess applications?

Finally, it is worth mentioning that the methodology employed in this research can be replicated in AC BESS applications with the aim of identifying the most relevant factors for battery reliability analysis. Xabier Dorronsoro: is the first author and has developed the core of the work.
