6. Conclusions Power line communications for HV battery systems is an attractive alternative communication technique for BMS data transmission and can pave the way for advanced single-cell monitoring methods such as electrochemical impedance spectroscopy being implemented in future smart cells and smart battery systems.
Additionally, high charging voltages can hasten the breakdown of solid electrolyte interface (SEI) , which reduces the reversible capacity and service life, and, in extreme situations, causes safety issues with lithium-ion batteries.
High-voltage cycling is a direct driver of intercrystalline cracking, and higher voltages lead to the formation of many irreversible dislocations and cracks, which is detrimental to the performance of the battery.
Recently, high voltage (HV) power line communication (PLC) has been proposed as an attractive and innovative communication technique to improve cost efficiency and reduce weight and wiring overhead in the battery system [ 20, 21, 22, 23, 24 ].
The electrolyte directly contacts the essential parts of a lithium-ion battery, and as a result, the electrochemical properties of the electrolyte have a significant impact on the voltage platform, charge discharge capacity, energy density, service life, and rate discharge performance.
