“…Several researchers have attempted various methods of integrating communication at a cell level; including capacitive coupling [9] , [10] , wireless radio [11] and to some degree low frequency power-line communication [12] , [13] , [14] but none of these solutions develop powerline communication in-situ of a cell, previous work has mounted externally and therefore sensor readings may not reflect the true state of health of the cell and the impact of embedded such technology within a pouch cell is undefined. There are a number of challenges associated with introducing sensors into Li-ion cell systems, including a harsh chemical environment, thermal effects causing expansion of materials and temperature gradients and electrical and mechanical interference can be encountered during normal cell usage.…”

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.
