Is the high-voltage modular energy storage system a battery

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.

Does a modular battery architecture affect performance?

Consequently, the topic of modular battery architectures is analyzed in this paper from the system’s point of view, as a detached change in one component might at the same time have a negative influence on another component of the drive train leading to an overall negative result for the performance and system losses.

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 .

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.

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.
