Speaker
Rapid growth in the electric vehicle market presents unique opportunities and challenges for on-board diagnostics (OBD), vehicle performance, and safety. Evolving regulations such as the 2022 California Air Resources Board (CARB) Advanced Clean Cars II (ACC II) rule have extended key OBD requirements for EVs. Providing standardized diagnostic codes, maintaining standardized OBD connections for third-party data access, and furnishing information about the vehicle's state of health (SOH) and drive motor efficiency are now all mandated under CARB regulations.
What emerging OBD requirements, challenges, and opportunities lie ahead for EV manufacturers?
Gain critical insights on the latest technical and legal challenges for electric vehicle OBD at the SAE On-Board Diagnostics Symposium Europe. Exponent's Sergio Mendoza, Ph.D., Senior Manager, Data Sciences, alongside Sidley Austin LLP's Aaron Flyer, will present findings from his recent study on extending OBD to EVs.
"Opportunities and Compliance Challenges in Extending On-Board Diagnostics (OBD) to Electric Vehicles (EVs)"
WEDNESDAY, MARCH 13 | 4 P.M. CET
Speakers: Sergio Mendoza, Ph.D., Senior Manager, Data Sciences; Aaron Flyer, Sidley Austin LLP
With increasing global demand for EVs, regulatory bodies, such as CARB and U.S. EPA, are anticipated to impose additional diagnostic systems on EVs. As previewed in CARB's November 2023 ACC II Amendment Workshop, more updates, including the adoption of additional industry interoperability standards and additional driving range performance metrics, are on the horizon. The overlay of an OBD framework on EVs poses complex technical and legal issues that may pose compliance challenges. As battery systems in an EV age, the control of these systems can be adjusted to maintain performance and safety. Standards like SAE J1979, SAE 1962, and SAE J2012 offer a framework and best practices for monitoring and reporting malfunctions in the powertrain components. However, the specifics of which systems and components to diagnose, as well as a rollout strategy, still need development. From both a technical and legal perspective, this talk will elucidate the challenges associated with battery SOH estimation and factors impacting battery life, as well as the advantages and challenges of rolling out regulatory requirements while the types and configurations of electric powertrains continue to mature and become established.
