Make it cheaper
- Charge off-peak. On a time-of-use plan, overnight power can cost a fraction of the peak price. Set the schedule in the car or the charger. Time-of-use plans.
- Don't charge to 100% every night unless you need it; most carmakers recommend a daily limit around 80% for battery life.
- Precondition while plugged in in winter, so the battery and cabin heat from the grid, not from range.
Efficiency figures are typical. Your car’s display shows its actual miles per kWh; winter driving can cut it by 20% or more.
