One of the straightforward strategies to connect a modular battery-based system to the grid is configuring a PCS based on the idea of parallelizing inverters, each one holding part of the total number of battery cells in series/parallel con- figuration. For the purposes of the present paper, this would FIGURE 1.
However, as the cell to cell imbalances tend to rise over time, the cycle life of the battery-pack is shorter than the life of individual cells. New design proposals focused on modular systems could help to overcome this problem, increasing the access to each cell measurements and management.
ABSTRACT 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.
The terminal voltage of a battery cell, in accordance with the battery's Thevenin equivalent circuit (battery model explained in section II), is composed of the cell's OCV, and the voltage drop across internal resistance (Karkuzhali et al., 2020).
This conversion improves the electrical source to align with the electrical network. These systems are sometimes referred to in academia as Power Electronics and may include subsystems for thermal management and monitoring of the Power Conversion Units .
