EV Road Trip Planner Calculator
Standard Trip
Calculate charging stops and costs for an EV road trip
EV vs Gas Trip Cost
Compare EV and gas vehicle trip fuel costs
Formula
Charging Stops = ceil((Trip Distance − Usable Start Range + Min Reserve) / Usable Range per Stop); Trip Cost = Energy Needed (kWh) × Cost per kWh; Energy = Distance × (kWh / mile)
Frequently Asked Questions
How long does it take to charge an EV on a road trip?
With DC fast charging (150-350 kW), most EVs can charge from 10% to 80% in 20-40 minutes. Charging slows significantly above 80%, so most road-trippers charge to 80% and continue driving. Total charging time depends on the number of stops needed.
How much does it cost to charge an EV on a road trip?
DC fast charging typically costs $0.30-$0.50 per kWh at public stations. A 300-mile EV might cost $25-$40 to fully charge, compared to $40-$60 in gas for a 30 MPG car over the same distance. Home charging before the trip is much cheaper at around $0.12-$0.15 per kWh.
Does cold weather really affect EV range?
Yes, significantly. At 0°F, EV range can drop 30-40% due to battery chemistry, cabin heating, and increased rolling resistance. At 32°F, expect about a 20% reduction. Pre-conditioning the battery and cabin while plugged in can help mitigate some of this loss.
