Identification

How to tell if your car has it

  • Fremont-built Standard Range Plus cars from April 2019 to October 2020. In Europe, the variant field (D.2) on the registration document or COC identifies the battery code.
  • The part number on the high-voltage battery label and Tesla service records are definitive. A VIN alone does not encode the cell supplier or pack code.

History

Lineage in the Panasonic 2170 family
