EV Acronyms

As might be expected in any specialized area, we use a lot of acronyms on this forum. Below is a list of some of the more common ones.

To Editors:
  • This list is only for acronyms, not for EV or Tesla specific terms like "Supercharger", "Vampire Loss", "Frunk".
  • Add new acronyms in alphabetical order, using the insert row button in the text editor. If you don't see this button, scroll down and click "Go Advanced".
  • If a cell ends with a link and you want to add plain text, either switch to code view (not recommended because finding the correct cell is tricky) or insert a new row , edit it and remove old row . If you don't see these buttons, scroll down and click "Go Advanced".
  • Whenever possible avoid ending a cell with a link. It makes adding plain text difficult.
