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
