Frequently Asked Questions
8.1.1 How accurate are the calculator’s predictions?
The calculator’s predictions are based on EPA-certified efficiency ratings and real-world charging data from Bolt EUV owners. Accuracy ranges from 90-95% for home charging scenarios and 85-90% for public charging, depending on specific equipment and environmental conditions.
The algorithms incorporate temperature derating factors (±15% for extreme temperatures) and charging efficiency losses (5-10% depending on charger type).
8.1.2 Why does DC fast charging cost more per kWh?
DC fast charging incurs additional costs due to:
- Infrastructure Investment: DC fast chargers cost $50,000-$150,000 to install
- Demand Charges: Commercial electricity rates include peak demand pricing
- Network Fees: Charging networks add service fees for maintenance
- Premium Location Pricing: Highway and urban locations command higher rates
- Idle Fees: Many networks charge fees if vehicles remain connected after charging completes
8.2.1 What’s the most cost-effective charging strategy?
For optimal cost efficiency, follow this hierarchy:
- Primary: Home overnight charging during off-peak hours (if available)
- Secondary: Workplace charging (often free or discounted)
- Tertiary: Public Level 2 charging for errands/shopping
- Minimal Use: DC fast charging only for travel >150 miles
This strategy typically results in 75-85% home charging, 15-20% public Level 2, and 5% or less DC fast charging.
