out of boredom, I did a short drive while taking some data with OBDEleven .. the idea is to know the impact of elevation change to batt consumption - something that most of us probably would already know, but I just like to put into a graph ..

the first picture is the elevation change from the route that I took (made using PlugShare.com), point-1 and point-3 is the same place (round-trip) .. the 2nd picture is from OBDEleven chart ..

most of the trips were done at 102 kph (with cruise-control) .. the temp was around 4C, the car was set at 22C .. wind was mild and sideways ..

the 2 regen at the middle of the trip was when I have to exit the highway and make a u-turn ..

some points :
  • on the steepest climb, the car was consuming 50kW, on the same spot on the way back , the car was producing around 38kW. Edit : Looking back at the data and the trip I took, I realized when we were going downhill, it's the small amount of regen for a period of time : average of 3.6kWatt for about 30s .. the last huge regen was when I'm exiting the highway ..
  • on the way back, when the car is climbing the last hill, we are actually using less energy (?)

some correction :

it's also show that my acceleration towards 102kph is more efficient compare to the ACC acceleration (using the res button) ..

Not the e-golf, but you might find the numbers here interesting from the point of view of consumption vs elevation change:
