Frequently Asked Questions
Why is my EV range lower than the EPA rating?
EPA ratings are tested under ideal conditions. Real-world range is typically 10-30% lower due to: temperature (cold reduces range 20-40%), driving speed (highway speeds reduce range 10-25%), climate control (AC/heat reduce range 10-30%), battery age (2-3% degradation per year), and driving habits. Expect 70-90% of EPA range in typical conditions.
How does cold weather affect EV range?
Cold weather significantly reduces EV range. Below 40°F, range decreases by 20-30%. Below 20°F, range can drop by 30-50%. This is due to battery chemistry, increased heating needs, and reduced regenerative braking efficiency. Pre-conditioning while plugged in can help minimize range loss.
Does driving speed affect EV range?
Yes, driving speed significantly affects EV range. Highway driving at 70+ mph reduces range by 20-30% compared to city driving due to aerodynamic drag. City driving (25-35 mph) often achieves better range than EPA ratings, while highway fast driving (75+ mph) reduces range by 25-35%.
How much does battery degradation affect range?
Battery degradation typically reduces range by 2-3% per year. After 5 years, most EVs retain 85-90% of original range. After 10 years, range is typically 75-85% of original. Modern EV batteries are designed to last 10-15+ years with proper care. Avoid frequent DC fast charging and keeping battery at 0% or 100% for extended periods.
