💡 How Driving Conditions Affect EV Range
Temperature is the biggest range factor. Cold weather (below 0°C) can reduce range by 20–40% due to battery chemistry slowdown and cabin heating. Hot weather (above 35°C) reduces range by 10–15% from AC and battery cooling.
Highway speed is the next biggest factor. EVs are most efficient at 40–70 km/h. At 100 km/h, expect ~20% less range. At 130 km/h, expect ~35% less. Air resistance increases with the square of speed — so a small speed increase costs disproportionate range.
400 km rated range in cold (−30%) at highway 130 km/h (−35%) with max heat (−18%): effective factor = 46%. Real range = 184 km — a 216 km reduction.
