Martin Bélanger explores the rapid transformation of the transportation and eMobility sectors driven by connected, autonomous, shared, and electric (CASE) technologies. Highlighting OPAL-RT’s decade of HIL innovation for ECUs, BMS, and powertrain validation, he examines the shift toward software-defined vehicles, zonal architectures, and evolving testing methodologies for EVs, eVTOLs, and more-electric aircraft.
