Hierarchical User-Driven Trajectory Planning and Charging Scheduling of Autonomous Electric Vehicles IEEE Trans. Transp. Electrif. (IF 6.519) Pub Date : 2022-08-05 Amin Mansour Saatloo, Abbas Mehrabi, Mousa Marzband, Nauman Aslam
Autonomous electric vehicles (A-EVs), regarded as one of the innovations to accelerate transportation electrification, have sparked a flurry of interest in trajectory planning and charging scheduling. In this regard, this work employs mobile edge computing (MEC) to design a decentralized hierarchical algorithm for finding an optimal path to the nearby A-EV parking lots (PLs), selecting the best PL

Reliability of Bolted Aluminum Busbars for Battery Systems: Effect of Nickel Coating and Corrosive Environment IEEE Trans. Transp. Electrif. (IF 6.519) Pub Date : 2022-08-03 Aksel Elkjaer, Geir Ringen, Ruben Bjørge, Catalina H. Musinoi Hagen, Sigrid Lædre, Niklas Magnusson
Bolted busbar connections are a simple and versatile connection method used in battery systems. Copper busbars are widely used for such bolted connections; however, aluminum offers the potential to save weight and cost. To date, the reliability of aluminum connections dimensioned for battery systems and the vulnerability to corrosion accelerants is not established. In this study, bolted aluminum connections
