“…Unfortunately, the cell impedance is too small to obtain the necessary amplitude. Using Rogowski coils as coupling elements for PLC, in order to avoid saturation effects of iron-core couplers at high current spikes, is proposed by Opako et al [593]. The high noise due to inverters and DC/DC converters on the medium is an important issue of PLC [563].…”

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 frequency domain solver turned out to be the most suitable solver for our problem type, because the PLC coupling elements, the Rogowski coils, exhibit high-curvature structures. In frequency domain, a tetrahedral mesh approximates a Rogowski coil with much less elements than a hexahedral mesh, used by the time domain solver [15]. This leads to a shorter simulation time.…”

“…We create the model of the current bar by segmenting analytic curves, which we covered with a thickness and width in order to obtain a 3-D model. The fourth basic element is the PLC coupling element, the Rogowski coil, as illustrated in Fig 4. Usually, Rogowski coils are used as measurement elements for alternating current in a conductor [32]- [34], but Rogowski coils can be also used as PLC coupling elements [15], [35]. The most important advantage is that Rogowski coils are air-cored, as a result of which saturation effects cannot occur.…”

A model of the transmission channel is essential for designing a power-line communication (PLC) system for a lithium-ion battery pack in electric and hybrid vehicles. Currently, measurements of lithium-ion batteries have to be performed by specially trained staff in safety chambers, because they might cause severe safety problems. A simulation model of the battery would therefore highly facilitate the analysis of different battery packs. Our approach is to extend an existing circuitbased model of the power-line channel with a 3-D electromagnetic (EM) model. The 3-D EM model is well capable of describing the inner environment of the battery pack as well as PLC coupling elements, which is necessary because power lines can also act as antennas. On the other hand, a fully detailed 3-D EM model cannot be simulated within a reasonable period of time. This article gives essential insights into future PLC systems for battery packs in order to ensure safe usage of electric and hybrid cars for the user and the environment.
