Ways to spend less
- Ask your utility about a time-of-use or EV rate and schedule charging for off-peak hours; the car or charger can do it automatically.
- Precondition the cabin while the car is still plugged in, so heating or cooling comes from the grid instead of the battery.
- Keep tires at the pressure on the door-jamb sticker; underinflated tires raise consumption.
- Drive 100 fewer miles a month: saves $3.73 at 15.2¢ per kWh.
