400 watts.
And here I thought you had gotten your units figured out..

DougWantsALeaf said:Stock tires with 16" EV01+ rims (about 5 lbs lighter than stock 16" rims) and 42psi.
One additional observation was that the AC in the S+ when set a couple degrees below ambient (say 86 when it's 90 out) once running for a few minutes only need about 400 watts/hr per Leaf Spy (sometimes as low as 350), yet kept the cabin with 4 of us very comfortable. I thought that looked like pretty good. I will need to test with the SV+ to compare.

BaronLithium said:Quick report here: I recently had a long trip down I-95 from Washington DC to North Carolina. Ran the A/C the whole time, and it ran fairly cold for the majority of the trip. Started fully charged from home at an ambient temperature of 85 F, tires a bit over-inflated (stock SV Plus tires at 45 psi) then drove around 110 miles to Richmond, VA and topped up at a EVgo station. That leg of the trip we averaged around 3.7 mi/kWh, and went 65 mph and 70 mph for speeds.
Next leg after that was 122 miles to an Electrify America station, speeds at primarily 70 mph again. Ambient temperature had dropped (sun had just set) down to 80 F. This leg we only got 3.4 mi/kWh.
After topping up at the Electrify America station, we drove another 60 miles down I-95 and held our speed to 65 mph. This leg we still could only obtain 3.5 mi/kWh.
Had anyone else experienced anything like this? I don't know if there was a change in the wind or if the battery was hot enough to reduce the efficiency on those later legs. Or am I missing some other variable in the efficiency equation?

BaronLithium said:lorenfb said:And the problem is?
I guess I'm trying to get a feel for what the normal expected range of efficiency is for this car. I'm still learning how to tune my internal gauge for what I should be expecting for highway range in less than optimal ambient conditions.
LeftieBiker said:Yes, and it can't be emphasized enough that speeds above 60MPH will kill your efficiency and range. 65MPH is a fair compromise; it still saps range, but not like going 70+...

DaveinOlyWA said:But beyond that, its power that affects efficiency the most, not speed (although it has a major impact as well).
watchdoc said:I'm not sure what your destination in North Carolina was but DC to Wilson, NC (middle of the state) is only about 262 miles. Why did you choose frequent short stops over a single long stop? What was your total drive time including charging?
DaveinOlyWA said:I take it you are resetting the trip computer after every charging session?
DaveinOlyWA said:Lets talk about driving and how "we" perceive our driving to be. We always think we have the steadiest foot on the planet. We couldn't be more wrong. But beyond that, its power that affects efficiency the most, not speed (although it has a major impact as well).
DaveinOlyWA said:Finally, Plugshare is your friend. Your Richmond stop looks to have a near 200 foot drop in elevation from your starting point. I have no idea how close the data is because you don't provide those details but the moral of the story is YMMV
Finally; a comment on your charging regimen. You get the least bang for your buck as the starting SOC of your charge session rises. You did nothing but charge to the top half of the pack. Does EVgo charge per minute there? If so, you doubled your charging costs at the least.

No. Not even close to being true for the middle 70% of the power curve
