Standardizing On-Board Diagnostics for Electric Vehicles

Exponent Presents at SAE International On-Board Diagnostics Symposium-Americas

Over the next decade, global demand for battery electric vehicles (BEVs) is expected to rise exponentially on the road to mass electrification. Driving the electric vehicle revolution is the lithium-ion (Li-ion) battery pack, one of the main components in a BEV powertrain and the leading electric vehicle battery technology today. While Li-ion batteries provide considerable benefits — from high-energy density to their ability to withstand repeated charging and discharging — Li-ion battery failures can result in serious loss of vehicle performance, large repairs and replacement costs, and potentially catastrophic safety risks including thermal runaway. Meanwhile, when it comes to electric vehicle diagnostics, currently no standard on-board diagnostics tool exists for BEVs.

At the SAE International On-Board Diagnostics Symposium-Americas, hear from Exponent Data Sciences Senior Manager Sergio Mendoza, Ph.D., on the present challenges and opportunities for standardizing BEV on-board diagnostics. Learn more and register below.

"Exponential Rise of Electric Vehicles: Challenges and Opportunities for the Development of Battery Electric Vehicle On-Board Diagnostics"

TUESDAY, SEPT. 12 | 11:00 A.M. EDT

Speaker: Sergio Mendoza, Ph.D.

Contributors: May Yen, Ph.D., P.E., CFEI; Artyom Kossolapov, Ph.D.; Francesco Colella, Ph.D., P.E., CFEI

This presentation will emphasize the need for standardized BEV on-board diagnostics, while analyzing existing BEV diagnostic tools and regulations and considering the perspectives of the vehicle's OEM, regulatory entities, and vehicle drivers.

Key Topics

  • How accurate diagnostics of critical components of the BEV powertrain are essential to alert vehicle functionality issues to a driver and to ensure long-term quality
  • Reviewing the existing body of BEV diagnostic regulations and the agencies responsible for their development
  • Examining different methods available for battery diagnostics, including experimental approaches, model-based strategies, and data-driven solutions
  • Insights on the challenges and opportunities for developing standardized BEV on-board diagnostics
