Hey there,

I recently acquired my first EV and have been having fun trying to get the best efficiency numbers out of it. I was at ~3.5mi/kWh (5.6km/kWh), but by slowing down and taking the other road not the highway to work I got it up to 4.4mi/kWh (7.08km/kWh). Part of that was accelerating relatively slowly as this is one tip that I heard. But I’ve been thinking about it and from a simple physics calculation it should take basically the same amount of energy to accelerate an object to highway speed whether you do it very quickly or if you spread that energy over a longer period of time.

Does anyone have any insight? I don’t mind granny accelerating but if I can have the zippy fun of accelerating an EV while still staying efficient that would be awesome too :)

Thanks!

    In electrical terms you’d be pulling more power from the batteries and over any cables, P=I^2R which would technically result in more losses in the conductor at higher currents. Also depends on the efficiency of the batteries and motor.
