TECH FOCUS: SUSTAiNABlE MOBiliTy DELIVERING ON THE PROMISE OF ELECTRIC VEHICLES By FRANK MENCHACA, President of Sustainable Mobility Solutions at SAE International.

Our own analysis, Electric Vehicle Charging Data Performance and Reporting, found the error codes of failed charging sessions arehttps://sms.sae.org/resources/electric-vehicle-charging-data-performance-and-reporting https://sms.sae.org/resources/electric-vehicle-charging-data-performance-and-reporting
