V9 and Range Anxiety

V9 and Range Anxiety

I bought my 2018 MX in July. Drove it about 3500km across Europe, always respecting batteries and chsrging levels. Range and consumption were GREAT (about 200 -220 Wh/km and full 400-430km range over 5 months or 10.000km)
BUT, as soon as V9 software was installed, DISASTER!
Consumption shot up to 300-370 Wh/km and would only level off to around 250-270 after many km of driving.
This gave me RANGE ANXIETY, when previously with V8 I had absolutely none.
Even the numbers between "SINCE LAST CHARGE" and "CURRENT TRIP" in terns of Wh/km are different! (for the very same trip and km!).
I posted photos in Tesla Twitter page, but no response.
I have seen some mX owners posting Utube videos about this. Any ideas, anyone?

The car seems to use more energy in the beginning of the trip. I don't think it's a good idea to compae a 1.8 km trip to 2000 km. I've noticed the same thing in the 3 after the update but my overall average still continues to go down.

ddolapsakis | December 29, 2018

lilbean, agreed. However, when I started off on 5.000km trip, right after an overnight software update, and my consumotii went crazy, I becane worried. And the difference in consumption between the current Trip and Since Last Charged was not there before with V8. I cant hepl but think that the V9 algorithms have something wrong with them.

lilbean | December 29, 2018

I also agree. I wonder if these numbers are actually more accurate.

burdogg | December 29, 2018

I haven't been on a long trip yet since version 9 so can't say...but you do realize as temperatures change - the consumption is going to go way up. You took delivery in July when consumption would be better... If you are using heat inside the X - yes, your consumption is really going to go up...especially shorter trips as the battery never gets warmed up. I have not noticed any changes in mine - Dec 2016 delivery...

I wonder if you are trying to make a correlation between software that doesn't exist...when in reality it is the season that is affecting you...(cold air is also denser air therefore creating more drag...therefore creating more energy to go through....There are many reasons why during the colder months that energy consumption goes up...)

lilbean | December 29, 2018

Good point.

patswin | December 29, 2018

I have to agree with OP on this. I have done a lot of trips in my X over the last two years. The longest distance between Superchargers is the Columbia, SC to Savannah, Ga for me. Last week on way to Orlando I had to charge longer than I have ever before and only had 5 miles remaining when I arrived in Savannah.
I only had one trip in winter in mountains of WV where I average above 400. Since update at least for first 1/2 hour of trip I am in the low 400s and usually finish around 370. Typical for me on trip to Florida is 353.
I find it strange that V9 could affect mileage so much but this has been a very dramatic increase in energy usuage for what had been pretty consistently in the 350s. I do believe/hope they will have a fix for this at some point like they usually do.

patswin | December 29, 2018

Except for the range anxiety part. Only had that once on very first road trip on same section of highway

ddolapsakis | December 30, 2018

Good points above. Fully agree that lower temps will affect consumption. However, the spike in consumption occurred under same temp and driving conditions (V8 vs. V9) and only in the first 30-50km. Then it levelled off. As for supercharging, 120kW is only for summer conditions. In winter max charging kW is 90kW or lower. I will wait for milder trmps in spring to compare versions and consumptions.
Upto mid-Dec with V8, I was able to drive with an average of 215Wh/km, in mixed conditions (city+rural highways), for more days, which is actually the optimal cinsumption. At 215 the projected range (middle screen) and the battery range (driver's dashboard) are equal. I hope that I will see this consumption again come spring.

lilbean | December 30, 2018

215 in the X? That’s lower than most are getting in the 3.

ddolapsakis | December 30, 2018

Yes. 215 in MX. I always try to verify a car maker's claim on mileage. Note: no AC/Heating involved.
In all my Priuses I was able to obtain the mileages Toyota claimed for over a month's worth if driving.
I was also disappointed that my suggestiin to Elon Musk (when he asked for ideas for improvements on Twitter) to include an analysis bar of the consumption (i.e. motors, heating/AC, BMS, lights, accessories etc) was not included in V9. That option display would definitely solve a lot of puzzles. Hyundai Kona-e has that and it helps a lot.

lilbean | December 30, 2018

Those are great numbers. I’ve heard of numbers so low in the X. You sh Do have zero range anxiety with those.

jimglas | December 30, 2018

I average aound 400 in my MX. FWIW. I have never seen 200 except going downhill.

ddolapsakis | December 30, 2018

I mostly use my MX in Greece, where charging points, especially on long routes, are rare. So going from a range of 450km to 350km all of a sudden, gives range anxiety, whem your next charging point is at 300km.
Jimglas: i m talking Wh per km, not per mile. Are you also referring to km?

jjgunn | December 30, 2018

@ddolapsakis
with V8, I was able to drive with an average of 215Wh/km

@lilbean - notice Europe / Wh/km (not miles)

I have 12k miles in 6 months & lifetime of 334 Wh/mi

As @burrdogg astutely points out, temp, wind, using the 6 kW heater all play a part in battery consumption.

Going uphill at 75 MPH, I got as high as 740 Wh/mi. I have a photo for proof.

Funny thing is, some folks worried about efficiency, it's no different than in an ICE but ICE's don't track gasoline digitally by the ounce or ml in Europes case.

burdogg | December 31, 2018

jjgunn - I was going to point that out to everyone as well - always note the words after the numbers :) wh/mi different than wh/km :)

Also interesting - my lifetime aver 28,000 miles is 333 :)

burdogg | December 31, 2018

oh 333 wh/mi :)

markcohen | December 31, 2018

@burdogg, where do you find the lifetime average?

TeslaTap.com | December 31, 2018

To get the lifetime average you need to never reset either the A or B trips. I've never reset my "B" trip and use it for lifetime info. For me, over about 18K miles, I have 326 wh/mi (204 wh/km?). This is almost identical to my last S with 38K miles. Short term is quite different, especially on short trips when it is cold out.

TeslaTap.com | December 31, 2018

Both cars above are S, not X. The X should require a bit more wh/mi.

markcohen | December 31, 2018

I had issues that required the SC to replace the AP and the MCU. Everything was reset at that point so even though I never reset my B trip either... I lost the data. Oh well.

jjgunn | December 31, 2018

burdogg | December 31, 2018

Also interesting - my lifetime aver 28,000 miles is 333 {Wh/mi} :)
------------
My 334 Wh/mi must've been when I blew away that BMW at the red light the other day. >;-}

@markcohen
Touch the car in the lower left corner then select "Trips" - You'll see all your info there.

burdogg | December 31, 2018

markcohen - well, guess you got a start over then :) But yeah, the only way to know is to never touch one of your trip meters. It would be a nice feature if Tesla had a special place as well that could never be reset so one couldn't accidentally reset their lifetime :)

jjgunn - Yeah, I am only 1 better than you because I have not had the pleasure to do that yet to a BMW - granted many jacked up trucks I have had the privilege to do it to :)
