Working draft proposal to:

  • Establish harmonized methods to determine in-vehicle battery durability performance of heavy-duty pure electric vehicles and heavy-duty off-vehicle charging hybrid electric vehicles,
  • Introduce State-of-Certified-Energy monitors that estimate battery health throughout vehicle lifetime,
  • Define minimum performance requirements for battery durability in an optional annex,
  • Establish test procedures for usable battery energy determination via test track driving, on-road driving, bidirectional power supply systems, or chassis dynamometer testing,
  • Implement a two-part in-use verification process verifying monitor accuracy and battery durability compliance through statistical sampling,
  • Collect field data to inform future revisions of performance requirements.
