Methodology
Auto‑Chase is a practical EV range estimator. It’s designed to help you understand which factors most affect range (speed, temperature, terrain) and to plan a safer buffer—not to replace the vehicle’s own navigation.
What we model
- Baseline efficiency: each model has a baseline consumption (Wh/mi) used as a starting point.
- Speed impact: higher speed increases energy use primarily via aerodynamic drag.
- Weather impact: temperature and cabin HVAC loads reduce effective range, especially in cold weather.
- Terrain profile: hills/mountains increase average energy use; regen can recover some energy on descents.
Inputs you control
- Start SOC and reserve SOC
- Speed
- Temperature and humidity
- Terrain profile
How to interpret the result
Treat the output as an estimate. Use it to compare scenarios (“What if I reduce speed by 5 mph?”), not as a guaranteed remaining‑miles number. Real‑world range varies with wind, tires, precipitation, battery health, and driving style.
Data sources & updates
Vehicle model parameters may come from a maintained dataset and are updated over time. If you spot an incorrect model, contact us at info@auto-chase.com.
Limitations
- No wind model (headwinds/tailwinds can be significant)
- No precipitation/road surface model (rain/snow/slush increase consumption)
- No charging curve modeling (this is range-only, not full trip timing)
