Planning Your EV Road Trip

Essential Planning Tools

Mobile Apps

• A Better Route Planner (ABRP): The gold standard for EV trip planning. Input your vehicle, route, and conditions for optimized charging stops
• PlugShare: Comprehensive database of all charging stations with real-time availability and user reviews
• ChargePoint, Tesla, Electrify America apps: Network-specific apps for planning and payment
• Exit Explorer: Find exits with EV charging along with other amenities

Trip Planning Strategy

Range Management

The 20-80 rule: Plan to arrive at chargers with 15-20% battery and charge to 80% for optimal speed. Charging from 80-100% takes significantly longer and is usually unnecessary.

Add buffer for:

• Cold weather (15-30% range reduction)
• Headwinds (5-15% reduction)
• Mountain driving (varies greatly)
• Highway speeds (higher speeds reduce efficiency)
• Charger availability (always have a backup plan)

Charging Stop Strategy

Multiple short stops vs. fewer long stops: Research shows several 15-20 minute charges are more efficient than fewer 45-minute charges. Fast charging slows dramatically above 80%.

Optimize your stops:

• Combine charging with meals, coffee breaks, or rest stops
• Check charger location amenities before stopping
• Consider time of day peak dining times mean crowded chargers
• Have backup locations identified in case primary is full or not working

Departure Preparation

• Start with a full charge (100% is fine for trip start)
• Pre-condition battery if cold weather
• Create accounts with major charging networks before your trip
• Download necessary apps and add payment methods
• Pack charging adapters (Tesla to CCS adapter increasingly important)
• Bring backup charging cable for emergencies

At the Charger: Best Practices

Charging Etiquette

• Don't ICE: Never park in charging spots without charging (EV or gas vehicle)
• Move promptly: When charging complete, move your vehicle within 5-10 minutes
• Don't unplug others: Never disconnect another vehicle without permission
• Share information: If a charger isn't working, report it in apps to help others
• Park properly: Follow marked parking spaces, don't block access
• Leave it clean: Dispose of trash, return cable properly

Troubleshooting Charging Issues

Charger Won't Start

• Ensure cable is firmly connected
• Try another cable or stall if available
• Restart your vehicle's charging system
• Check app for error messages
• Contact network support (numbers usually posted on charger)

Slower Than Expected Charging

• Battery temperature affects charging speed (too hot or too cold slows charging)
• High state of charge (80%+) naturally slows charging
• Power sharing at busy stations can reduce individual charger output
• Older chargers may have lower power output

Safety Considerations

• Avoid charging in heavy rain or standing water if possible
• Don't force connections damage can occur
• Stay aware of surroundings, especially at night in unfamiliar areas
• Keep vehicle doors locked while charging
• Trust your instincts if a location feels unsafe, go to your backup option

Cost Considerations

Pricing Models

Per-kWh pricing:

• Most transparent: pay for electricity consumed
• Typical range: $0.30-$0.60/kWh at DC fast chargers
• Example: 50 kWh charge at $0.40/kWh = $20

Per-minute pricing:

• Common where per-kWh isn't allowed
• Usually tiered based on charging speed
• Encourages moving vehicle when done
• Less predictable for budgeting

Membership/subscription models:

• Monthly fees for reduced per-session costs
• Worthwhile for frequent road trippers
• Electrify America Pass+: $4/month for $0.12/kWh discount
• EVgo subscriptions: various tiers available

Cost Comparison

Highway charging costs approximately equivalent to paying $3-$5 per gallon for a 30 MPG vehicle. While more expensive than home charging, still generally competitive with gasoline, especially for efficient EVs.

Seasonal Considerations

Winter Driving

Cold weather significantly impacts EV performance:

• Range reduction: Expect 20-40% less range in freezing temperatures
• Preconditioning: Warm the battery and cabin while still plugged in
• Conservative planning: Add 30% buffer to planned charging stops
• Slower charging: Cold batteries charge slower; many EVs precondition automatically
• Winter tires: Improve safety but slightly reduce range

Summer Driving

Heat also affects efficiency, though less dramatically:

• Air conditioning: AC use reduces range 10-15%
• Battery cooling: Most EVs manage this automatically
• Parking: Seek shade when possible to reduce cabin cooling needs
• Range impact: Generally less severe than winter
