A Comprehensive Study on Cyber Attack Vectors in EV Traction Power Electronics

Electric vehicles (EVs) have drastically changed the auto industry and developed a new era of technologies where power electronics play the leading role in traction management, energy conversion and vehicle control processes. Nevertheless, this is a digital transformation, and the cyber-attack surface area has increased considerably, to the point that EV traction power electronics are becoming vulnerable to various cybersecurity risks. This paper is able to provide its expertise on possible cyber-attack vectors which can attack important parts of the traction, powertrain, including things like inverters, motor controllers, and communicated systems within the embedded bits. Using the (STRIDE) threat modeling framework, the research outlines and groups the vulnerabilities of the architecture and runs some attack simulations, such as the Denial of Service (DoS), spoofing, firmware manipulation, and data injection. The experiments prove the fact that a slight interruption in the control signal, the sensed data may lead to the severe working implications, such as unstable sensor values of the torque, abnormal voltage shifts, and entire system freezes. These results highlight the high priority on the need of injective embedded intrusion preventive mechanisms and secure design of firmware in EV powertrain electronics. In this paper, the author makes his contribution to the general body of knowledge that underpins the links existing between cyber security practices and the peculiar needs of automotive power electronics.

Synergistic Development of Cybersecurity and Functional Safety for Smart Electric Vehicles

The introduction of Smart Electric Vehicles (SEVs) represents an increasingly disruption on automotive area, once integrates advanced computer and communication technologies to highly electrical cars, which come with high performances, environment friendly and user friendly characteristics . But the increasing complexity of SEVs prompted by greater dependence on interconnected systems, autonomous capabilities and electrification, presents new challenges in cybersecurity as well as functional safety. The safety and reliability of such vehicles is paramount, as unsafe or unreliable operation in either case represents an unacceptable risk in terms of the performance of the vehicle and safety of the passenger. This paper investigates the integrated development of cybersecurity and functional safety for SEVs, emphasizing the requirement for the parallel development of these domains as components that are not treated separately. In SEVs, cybersecurity is quite crucial in order to prevent the threats of hacking, data breaches and unauthorized access to vehicle systems. Functional safety ensures that important vehicle functions (braking, steering, battery control, etc.) keep working even if some part fails. This convergence of functional safety issues with cybersecurity issues is becoming more crucial, since a security incident can result in a failure of catastrophic consequences for a functional safety system and, conversely. This paper reports the current state of cybersecurity and functional safety standards for SEVs, highlighting challenges that include the weaknesses of communication networks, the potential security threats of over-the-air updates, and the demand for real-time responsive systems for failure.

Active Short Circuit and Safe Discharge Mechanisms in Multi-Phase Inverters During Critical Failures

The multi-phase inverter has become more complicated, particularly in an Electric Vehicle (EV)'s power train, which requires a robust fault protection system. The proposed active short circuit and safe discharge mechanisms are also included in this work, dedicated to multi-phase converters in failure conditions. With silicon carbide (SiC) power modules increasingly used in high efficiency and high-power applications, the reliability under fault conditions is an extremely important factor. Cascading failures and permanent damage will occur in multi phase inverter systems if short circuit faults are not prevented. The proposed method combines one centralized short circuit detection, active phase shorting and controlled discharge to make these structures more robust. The on chip active short circuit mechanism isolates the affected phases quickly preventing faults from spreading to other areas of the inverter and the safe discharge mechanism controls energy discharged in fault scenarios, which reduces the thermal stress placed on essential components. The experimental results show that the proposed mechanisms can effectively enhance a fault detection performance, system response during faults, and the operation as whole at faults over the several existing methods. These mechanisms are demonstrated to be very important for enhancing the safety and reliability of multiphase inverters, especially for critical applications of such inverters as EV where high operational security is required.
