Question 1

How is EV range calculated?

Accepted Answer

Range ~ usable battery capacity (kWh) / consumption (kWh/100 mi) * 100. Conditions like speed, temperature, HVAC, terrain, and load affect consumption.

Question 2

What is usable capacity?

Accepted Answer

The portion of the battery available to the driver; manufacturers often reserve a buffer to protect longevity.

Question 3

How does temperature affect range?

Accepted Answer

Cold increases internal resistance and HVAC demand; heat raises HVAC load—both increase consumption.

Question 4

Can I include charging stops?

Accepted Answer

Yes—enter a starting SoC, target SoC at stops, and charger power to estimate travel time and segments.

Question 5

What driving speed should I use?

Accepted Answer

Higher speeds increase aero drag (~speed^2), so consumption rises quickly above urban speeds.
