Abstract

Potential issues of front-end converters of wireless power transfer system modules for extreme fast charging are discussed and analyzed in this study in order to provide some recommendations to defend against attacks on electric vehicles and charging systems. Compared to conventional low-power charging systems, the impact of a cyber-attack might be more detrimental in high-power / fast charging systems since the fault energy levels would be inherently higher both on the grid- and vehicle- side converters. In order to analyze the potential issues that might be a result of cyber-attacks, the negative scenarios are reviewed in this study which include interfering with the grid-side controllers, establishing fake communications between the vehicles and the charging stations, and interfering with the battery management system functionalities. A 100-kW stationary wireless power transfer system with a series-series resonant compensation network is used as a representative system in the analysis. Potential damages and the fault energy levels for selected fault scenarios are investigated. The system is simulated to verify the analysis results. On the basis of the discussed worst-case study, a set of hardware design-level solutions are recommended in this study to provide cyber protection.
