3Low-Power Cellular Telemetry Solution for Electric Vehicles
Mihail Vorobiov, Raymond Nemeth, Alexis Polycarpou, Dan D. Micu
A low-power system that reads the solar vehicle's CAN bus (BMS, two MPPTs, inverter, dashboard, auxiliary power) and sends the data, encrypted, over LTE to a server. It was built for the vehicle the team raced at iESC 2024 and evaluated on power use, latency, bandwidth and error rate.

Vincent Dury, Lionel Steeve Gounou Kouontchou, Mihai Chirca, Stefan Breban
Optimises two versions of an in-wheel permanent magnet synchronous motor with toroidal winding for propelling a light solar vehicle. Finite-element analysis suggests slotless machines suit the job when rated power is low.

Danuț-Marian Popa, Florin Jurca
Compares five outer-rotor synchronous motor designs of up to 1 kW to find a light, efficient in-wheel motor for a solar vehicle. The first author, Dănuț-Marian Popa, led motor design in the Solis team.

2Investigation on the Aerodynamics and Energy Gain from Roof-Mounted Photovoltaic Systems for Plug-In Hybrid and Electric Vehicles
István Barabás, Ion Matei, Stefan Breban
Simulates the aerodynamics of a production vehicle with and without roof-mounted solar panels to measure the added drag and the energy gained. At low city speeds the panels add range; at higher speeds a moderate cut in speed recovers most of the loss.

DOI 10.3390/wevj17090453 In-wheel motor2023In-wheel Slotless Permanent Magnet Synchronous Motor for Light Electric Vehicle Propulsion
Mihai Chirca, Marius Alexandru Dranca, Stefan Breban, Loránd Szabó
Proposes an exterior-rotor, radial-flux, slotless in-wheel motor with a three-phase toroidal winding for a light electric vehicle. Finite-element analysis shows good performance for light traction.
