When it hits hardest
winter peak
Cold weather cuts EV efficiency 20-30%, increasing kWh per charge.
Ways to cut the cost
- 1
Charge during off-peak hours (midnight-6am typically)
Saves 30-60% on time-of-use rates
- 2
Set charge limit to 80-90% for daily use
Preserves battery life and avoids top-of-charge inefficiency
- 3
Use scheduling to avoid charging during peak summer afternoon
Cuts grid load + saves money on demand charges
