Bruno Lequesne

Title : Electric Machines for Automotive Propulsion: History and Future

Dr. Bruno Lequesne, USA


It has been over twenty years now since the GM EV1 and the Toyota Prius hybrid were launched, one using an induction motor and the other an interior permanent magnet machine. This is just enough time to start to look at these machines from a historical perspective, examining early technical choices and changes over time to the present day, focusing on systems that were commercialized by automakers. The talk will draw from published reports and teardowns of these motors to explain and quantify improvements over time. The presentation will then logically follow with an attempt to extrapolate into the future, looking at what is likely and perhaps less likely to be seen in future electric and hybrid vehicles, from a point of view of materials, topology.

Title : Ultra fast charging method for lithium ion batteries considering degradation

Song-Yul Choe, Ph.D, Prof., Auburn University, USA


Reduction of charging time is one of challenging issues for different applications of lithium ion batteries. Particularly, it is true with electric vehicles because a relatively long charging time compared with that of internal combustion engines presents one of barriers for wide acceptance of EVs. In addition, the charging time is elongated as more battery is installed to extend the drive range.
In fact, the charging time can be simply reduced by increased charging current that in return adversely accelerates degradation due to enhanced side reaction and lithium deposition reaction. Currently suggested charging methods such as constant current and constant voltage, constant power, multi stage constant current or any of the combined above do not take into account minimization of the reactions. Moreover, guidelines for charging methods provided by manufacturers are not based on the fundamental understanding in ion transport and electrochemical reactions that degrade battery.
A research team at Auburn University led by Dr. Choe proposes solutions for an ultra fast charging method that is designed using a reduced order electrochemical model that describes mechanisms of ion transport and the chemical reactions, which lead to not only reduction of charging time but also minimization of degradation compared with those by classical charging methods.
Side reactions and lithium deposition reaction are the reactions that cause both capacity and power loss. The side reaction causes growth of SEI and creation of extra deposit layer, loss of active materials and consumption of solvents of electrolyte. The lithium disposition reaction takes place at the anode particle surface and is called lithium plating that creates dendrites that potentially induces an internal short circuit and as a result safety of battery system can be endangered.
According to studies for the relationship between high charging C rates and lithium plating and side reaction, increased charging current induces saturated lithium ions concentration at the surface of anode particles, which results in a high side reaction and lithium plating. Elevated temperature promotes both reactions, simply because of high mobility of ions and associated reactions. On the other hand, the negative anode potential creates a favorite condition for formation of lithium plating. Moreover, according to conducted experiments, lithium ions in the plated lithium can be recovered by negative charging currents.
Based on these facts, a new fast charging method is designed by combining negative pulse and different limitations that include anode potential, side reaction rate and cutoff voltage, which is called an ultra fast charging method with negative pulse (FCNP). The internal variables such as potentials and ion concentrations are estimated using ROM with extended Kalman filter and compared with preset limitations to determine the charging protocol that consists of pulse, multi-stage of currents and constant voltage.
Experimental results of the method have shown that the charging time is reduced to around 37% up to 40% SOC and 13% up to 80% SOC. The capacity loss by FCNP is 13% less at the 60 cycles than that by 3C CC/CV charging. From beginning to 60 cycles, the capacity loss by the FCNP is similar to that by 3C CC/CV charging.

Title : Blockchain Security

Dr. Yousef Al-Hammadi, United Arab Emirates University, UAE


Blockchain can provide trust to peer-to-peer shared distributed ledger that is immutable and assure the integrity of blocks that can hold any type of data in the chain. This type of technology has reforms the government and business processes to be more secure, transparence, fast, efficient and reduce the cost.
Hash function is an example of cryptographic solution that can assure the integrity of each block and immutability of all blocks in the chain. Public key infrastructure is used to sign digitally the transaction and can be used for verification and block validation by using the consensus, which allow adding new validated block to the chain and eliminating invalid transactions. The identity management and key management for authentication either for public or permissioned blockchain is another security issue that is required to consider. ISO/TC 307 expected to release no later than 2021.
Blockchain applications such as Bitcoin, FinTech, smart contracts, etc. require also security protection such data at transit, communication, off chain, and storage. It expected that in 2019, the market value of blockchain application would be more than 38% of 2018.

Title : Testing and Certifying Artificial Intelligence Models for Autonomous and Connected Vehicles

Dr. Ernesto Damiani, Khalifa University of Science and Technology, UAE


Connected and autonomous vehicles increasingly incorporate Machine Learning (ML) models for solving autonomous navigation and control issues, including avoiding collisions that are caused by humans’ distracted driving. The code behind these ML models is mostly standard and their behavior depends heavily on their training, Traditional assurance techniques, which supported test-based safety and security certifications, require radical re-thinking to work in this scenario. While statistical testing provides a promising line of attack to this problem, there is lack of literature on its concrete application for online and offline testing of ML models embedded is autonomous vehicles. The keynote talk will present practical testing techniques for security and safety based on the Multi-Armed Bandit paradigm, and discuss the use of Artificial Intelligence techniques for generating such tests, using ML models to test other ML models verifying their compliance, not only to security and to safety properties, but also to ethical behavior guidelines.

Title : Security for Autonomous and Connected Vehicles

Dr. Chan Yeob Yeun, Khalifa University Science and Technology, UAE


Connected and autonomous vehicles are driver-less vehicles that incorporate various technologies to provide efficient and safe navigation by sensing their environments. Vehicles connectivity allows them to share location, speed, as well as weather, road and traffic conditions with their infrastructure. Their automated capability relies on onboard sensors to survey their surroundings to decide their activities during the driving trip. The connectivity and automation features require more sensor to be integrated and more computation resources to provide reliable and robust transportation infrastructure. However, as the computation resources and connectivity and automation levels increase, the system becomes more vulnerable to security attacks. Emerging connected and autonomous vehicles help in saving human lives by reducing traffic collisions that are caused by humans' distracted driving. Moreover, they help in minimizing traffic congestions and managing traffic flow, especially in urban environments. However, despite the various advantages of connected and autonomous vehicles, there are some foreseeable challenges and Cyber threats that persist which target the safety and the privacy of their users. In addition, connected and autonomous vehicles security challenges became a big concern for both industry and research community due to the large number of attacks that target their networks to disturb their communications, access private data or target the integrity of the data which may threaten human lives. Also, Vehicular ad-hoc network (VANET) vehicles are considered as connected and autonomous vehicles that communicate and share information without the need for an infrastructure through ad-hoc network. There are various types of threats and attacks targeting different security services in connected and autonomous vehicles. These Cyber security threats including eavesdropping, man-in-the-middle, data modification, masquerading, jamming, replay attacks and GPS spoofing that are posed to confidentiality, integrity, authenticity, availability, non-repudiation and physical security. There is lack of literature detailing the vulnerabilities and mitigating techniques for connected and autonomous vehicles' control unit. Moreover, the type of personal data stored in the vehicle, their way of protection and who owns them remain unclear. Thus, the invited talk will be discussed about the Cyber security threats and attacks that are targeting the security services and the methods presented in the literature to mitigate their risks to an acceptable level. Also, research direction should focus on the security gaps of connected and autonomous vehicles that require attention from researchers.
