Automotive cybersecurity is a challenge that must be considered as part of the vehicle electrification movement. Cybersecurity of the Battery Management System (BMS) is of particular interest due to its critical role in vehicle functionality, performance and safety as well as its multiple connections to external systems. Despite this, it is a topic that has scarce coverage in literature to date. This paper discusses potential attacks on a generic conventional BMS, outlining the methods and consequences. It also explores the future BMS trends and how this may affect the nature of attacks, and the reach and magnitude of the consequences. Finally, it discusses possible mitigation strategies that if incorporated could reduce the likelihood and impact of potential cybersecurity problems for this system.
