Tesla has been offering discounts at select stations in California as a way to try and avoid congestion during peak periods.
The automaker considers off-peak hours to be between 7:00pm and 10:00am.
Tesla has now updated that window to start off-peak hours later, but has also shifted them to end later.
According to an email sent to owners in California shared by Ramsey T on Facebook, the new off-peak window runs from 9:00pm until 11:00am.
Exact rates will vary by location, and can be viewed by tapping on the Supercharger map pin on your in-car display.
