6 FAQs about [Modularization of battery packs for energy storage power stations]

What is a modular battery-based energy storage system?

A modular battery-based energy storage system is composed by several battery packs distributed among different modules or parts of a power conversion system (PCS). The design of such PCS can be diverse attending to different criteria such as reliability, efficiency, fault tolerance, compactness and flexibility.

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.

Can batteries be used in grid-level energy storage systems?

In the electrical energy transformation process, the grid-level energy storage system plays an essential role in balancing power generation and utilization. Batteries have considerable potential for application to grid-level energy storage systems because of their rapid response, modularization, and flexible installation.

How can a fully modular power electronic architecture improve battery design?

Moreover, different legal rules would apply for certain aspects of the battery design such as insulation. Moreover, a further increase of flexibility could be reached by a fully modular power electronic architectures, e.g. modular inverters and machines.

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.

Will a modular battery system affect the volume of the drive train?

Yet it can be said that in general also the volumetric energy density of the cells is higher for high energy cells and therefore it can be assumed that the proposed concept with a modular battery system will not have a negative effect on the volume of the drive train.
