How to lower the cost of running a Level 2 EV charger

Level 2 chargers run on a 240V circuit and typically deliver 7.2 kW on a 40-amp circuit, or up to 11.5 kW on a 60-amp circuit. Your car decides how fast it accepts power. Two hours a day at 7.2 kW is about 14 kWh, enough for roughly 40–50 miles for most EVs. Charging overnight on a time-of-use plan can lower the cost considerably compared with the average rate shown here.

  • Ask your utility about EV or time-of-use rates and schedule charging overnight.
  • Charge to 80% for daily driving — it's faster and better for the battery.
  • Precondition the car while plugged in during cold weather.
