Negative fuel consumption

If only we could always drive down hill

you would need to have a less than 90% or so SOC in order to add range like that.
the reality is that you expended more energy getting up that hill than you'd recover going down the same hill.

I drove over the mountains from San Clemente to Palm Desert, CA. I had 48% battery range at the top of the last pass and the NAV system predicted we would arrive 35 miles later with 52%....and sure enough that is what happened.....Of course what goes down, must go up and with the conservation of energy still best to drive on a level surface.

Really? It looks like it’s only about 0.5% of the battery at an average rate of around 3.7kW. It’s not very high. I’d be surprised to learn it had to be at 90% to recup at 3.7kW.

@Gareth Swain do you know what your elevation change was?

Just build a road like these stairs and you’re good to go.

I experienced the same thing on a road trip last week. Gasoline powered cars may burn very little fuel going down a long downhill grade, but it doesn’t add gas to the tank. ?
