Electric vehicles consume significantly more energy when climbing a gradient, losing range faster. Regeneration during descent helps recover lost miles.
Driving the same road both up and down a mountain pass, like in the Loveland Trials EV test, provides accuracy in comparing energy spent going up and regenerated going down.
EV batteries have an ideal temperature range for maximum range. Temperature changes during mountain passes can impact range, requiring energy to maintain optimal battery conditions.
In a TFLEV test, the Hyundai Ioniq 5 with 77.5 kWh battery lost 118 miles of range in 74.1 miles climbing Loveland Pass, demonstrating the impact on range in challenging terrains.
