How to Calculate EV Driving Range
Your EV's real-world range depends on three factors: current state of charge (SOC%), total battery capacity (kWh), and energy efficiency (miles/kWh). Available energy = capacity ร SOC% รท 100, and maximum range = available energy ร efficiency.
To protect battery health and avoid range anxiety, it's best to keep a 10% buffer. The recommended range shown accounts for this margin. Always plan charging stops with extra buffer for traffic, detours, or cold weather.
Real-world efficiency varies with speed, climate control use, and temperature. For trip planning, use a slightly conservative efficiency estimate.
Frequently Asked Questions
Most EVs average 3โ4 miles/kWh in moderate conditions. Efficient city cars like the Tesla Model 3 can reach 4โ5 mi/kWh, while larger SUVs may average 2.5โ3.5 mi/kWh.
Regular 100% charging accelerates battery degradation. Most EV manufacturers recommend daily charging to 80% and saving 100% for long trips. Check your vehicle's charging settings.
