Understanding Electric Vehicle Range
Range anxiety is a common concern for new EV owners. While manufacturers advertise a specific range based on EPA or WLTP cycles, real-world mileage varies significantly based on physics and environmental factors. This Electric Vehicle Range Calculator helps you estimate how far you can drive based on your specific battery size and current conditions.
Key Factors Affecting EV Range
- Battery Capacity (kWh): The size of your "fuel tank." Note that EVs have a "gross" capacity and a "usable" capacity. Always use the usable capacity for accurate calculations.
- Efficiency (Wh/mi): This is the EV equivalent of MPG. It measures how many watt-hours of energy are needed to travel one mile. Lower numbers mean better efficiency. For example, a sedan might use 240 Wh/mi, while a large electric truck might use 450 Wh/mi.
- Speed: Unlike gas cars, EVs are often less efficient at high speeds due to aerodynamic drag. Driving at 75 mph consumes significantly more energy than driving at 55 mph.
- Temperature: Batteries depend on chemical reactions that slow down in the cold. Additionally, heating the cabin uses battery power (unlike gas cars which use waste heat from the engine), which can reduce range by 20-40% in freezing conditions.
Common EV Efficiency Ratings
If you don't know your vehicle's efficiency, you can use these average approximations:
| Vehicle Type | Approx. Usable Battery | Average Efficiency |
|---|---|---|
| Compact EV (e.g., Bolt, Leaf) | 60 – 65 kWh | 240 – 280 Wh/mi |
| Efficient Sedan (e.g., Model 3) | 55 – 75 kWh | 230 – 260 Wh/mi |
| Mid-Size SUV (e.g., Model Y, ID.4) | 75 – 82 kWh | 280 – 320 Wh/mi |
| Large Truck/SUV (e.g., F-150 Lightning) | 98 – 131 kWh | 400 – 480 Wh/mi |
How to Calculate Range Manually
The math behind EV range is straightforward:
Range = (Usable Battery kWh × 1000) ÷ Efficiency (Wh/mi)
However, this gives you the "rated" range. To find the real-world range, you must apply factors for weather and speed. For example, if you are driving in freezing temperatures, you might multiply that result by 0.70 (70%).
