“…Since these cells do not necessarily have to be cells of the same type or even battery cells, the smallest unit is referred to as Energy Storage Unit (ESU) (Figure 6a). However, in the case of multiple cells, the flexibility of having influence on each individual energy storage decreases [374].…”

This review provides an overview of new strategies to address the current challenges of automotive battery systems: Intelligent Battery Systems. They have the potential to make battery systems more performant and future-proof for coming generations of electric vehicles. The essential features of Intelligent Battery Systems are the accurate and robust determination of cell individual states and the ability to control the current of each cell by reconfiguration. They enable high-level functions like fault diagnostics, multi-objective balancing strategies, multilevel inverters, and hybrid energy storage systems. State of the art and recent advances in these topics are compiled and critically discussed in this article. A comprising, critical discussion of the implementation aspects of Intelligent Battery Systems complements the review. We touch on sensing, battery topologies and management, switching elements, communication architecture, and impact on the single-cell. This review contributes to transferring the best technologies from research to product development.

The modular multilevel battery (M2B) is a novel approach to integrate battery storage into the electricity grid. This paper obtains the efficiency a nd fi nancial be nefits of a working prototype system, compared to conventional systems for frequency containment reserve (FCR). The efficiency i s determined with a low-level simulation that models the conduction losses on the circuit, the MOSFETs' switching and conduction losses, and the system consumption. The simulation model shows, that the efficiency i s s uperior t o c onventional i nverters over the entire operating range. The operation for FCR shows a cost-reduction of 50 % for transactions on the intraday market, resulting in a 72.9 % higher net-profit after 10 years.

“…A large amount of serially connected battery cells increases the need, complexity, and costs of battery balancing to maximize the usable battery capacity in the presence of varying states-of-charge. [3] This paper presents a novel BESS topology: The Modular Multilevel Parallel Converter based Split Battery System (M2B) presented before [4,5]. The general advantages are described, and the increase in usable battery capacity is highlighted.…”

Battery Storage Systems are increasingly deployed in the grid for commercial applications and ancillary grid services. Current state-of-the-art systems suffer from several drawbacks regarding safety, efficiency, and costs. This paper presents a novel approach that avoids major challenges for the production, installation, and operation of battery storage systems. Based on modular power electronics the central inverter is omitted and each battery module acts according to grid voltage and power requirements. This leads to the flexibly adjustable m-Bee system with the highest efficiency and failsafety. This new topology also increases the usable battery capacity compared to state-of-the-art systems.
