The 80/20 Rule for Road Trips
The single most important tip: charge to 80%, not 100%. Charging from 20% to 80% is fast (20–30 min at 150+ kW). The final 20% to 100% takes as long again. On a road trip, leave at 80% and plan your next stop before you drop below 15–20%.
How Far Apart Should Charging Stops Be?
Plan stops roughly every 150–200 miles at DC fast chargers. This leaves comfortable buffer for detours, traffic, and temperature effects on range. Most major US highways (I-5, I-95, I-40, I-10) now have DC fast chargers every 50–80 miles along the route.
Best Apps for Route Planning

Cross-Country USA: Key Charging Corridors
| Route | Distance | Coverage |
|---|---|---|
| LA → San Francisco (I-5) | 380 mi | Excellent – Tesla, EA, EVgo every 40–60 mi |
| NY → Boston (I-95) | 215 mi | Excellent – dense network, 1–2 stops needed |
| Chicago → Denver (I-80) | 1,000 mi | Good – some rural gaps, Tesla Supercharger essential |
| Miami → Atlanta (I-95/I-75) | 660 mi | Good – EA every 60–80 mi, Tesla dense |
Europe Road Trip Tips
Europe's highway charging is excellent on the Ionity corridor (major motorways across 24 countries, 350 kW). For the best rates, get a charging membership before you go:
- Ionity Passport: €0.35/kWh vs €0.79/kWh walk-up
- ADAC e-Charge: Works at Ionity, EnBW, Allego – great for Germany/Austria/Switzerland
- Plugsurfing / Chargemap Card: Single card for 400,000+ stations across Europe
Top Tips to Avoid Charging Anxiety
- Always have the next charging stop planned before you leave each station
- Have backup networks: if ChargePoint is full, EVgo might be free nearby
- Pre-condition battery in winter – use the navigation for automatic heating
- Drive 65–70 mph instead of 80 mph – increases range by 15–20%
- Check PlugShare reviews for reliability before relying on a remote charger
