How speed and temperature affect EV range — via drivingdotca ElectricVehicles

That’s right, less than two-thirds of the battery’s output was being directed to the wheels, the rest being consumed keeping me and the F-150’s electrolyte toasty. Now, a few. First, the F-150’s cabin is freaking huge, so it needs more heat and fan circulation to keep it warm, both mechanisms consuming precious lithium-ions.

Coupled with the fact that drag is proportional to the square of velocity, speed has much greater influence than temperature the faster you drive. At 50 kilometres an hour, for instance, the difference between 19 C and 0 C would be about a 20-per-cent drop, while at 110 km/h, it’d be closer to 8 per cent. Geotab even has

And finally, anticipating all the Tesla owners ready with their customary “but my Model S…” retorts, the company’s research suggests there’s not much difference between brands, the best EVs retaining 60 per cent of their range at -15 C and the worst about 45 per cent. In other words,battery-powered vehicles suffer significantly when the mercury dips dramatically.
