EV Efficiency Converter
This page brings together a powerful set of EV calculators designed to help you plan, compare, and optimize your electric driving experience. From estimating trip energy use and charging times to comparing running costs with gas vehicles, these tools make it easy to translate efficiency data into real-world decisions. Whether you’re planning a road trip, evaluating charging options, or just curious about your vehicle’s performance, you’ll find clear, accurate, and customizable calculators right here—all without sending your data anywhere.

Trip Energy & Cost
Tip: Use your car’s lifetime average. Losses estimate AC/DC overhead (cables, heat, taper).
Charging Time Estimator
Assumes relatively flat charge power; DC fast charging will taper at higher SoC.
Range Estimator
Quick model: colder temps, winter tires, wind and rain reduce range. Adjust as needed.
Running Cost — per 100 km & per km
Gas vs EV — Cost & Savings
Compares fuel cost per 100 km (or per 100 mi) and estimates savings for a chosen distance.

Notes & Assumptions
- All results are estimates for planning and comparison. Real-world outcomes vary with speed, elevation, temperature, wind, traffic, tire type/pressure, HVAC use and battery conditioning.
- EV efficiency input supports either kWh/100km (metric) or Wh/mi (imperial). The unit system picker adjusts labels and calculations.
- Charging time uses a simple average power model. DC fast charging typically tapers above ~50–70% SoC.
- No data is stored or transmitted. All calculations run in your browser.
