Atto 3: Will the Cold Affect my Range and Charging Speed? Chilly Winter Night Trip! 🥶🥶 Episode 76

[@Petlaw99]

Cold weather very definitely affects the range/consumption. My Model Y LR uses around 21 kWh/100 km on the Hume highway at that time of the morning in those temperatures but drops to 17 or so on a warm day.

Yeah that's quite a difference! Thanks for your comment

[@brettbarnes7370]

Good test, did you run the heating all the way during the trip?

[@bydatto39461]

I had the heating on some of the time. I was wearing warm clothes, but yeah the heating probably added to the economy.

[@brettbarnes7370]

@@bydatto39461 Just another question if you don’t mind. As you do a lot of trips from Kalgoorlie in your ATTO3 do you carry a spare wheel and tyre or do you rely on the supplied sealer?

[@jimgraham6722]

Thanks best range speed in the Atto3 is 85kmh. At that speed you should get around 15KWhr per 100km. The Atto is quite draggy and energy consumption rises quickly above 90 kmh.

Unfortunately it's a busy single lane highway, so going 85km/hr would probably piss of a lot of drivers! Especially during the day when I mostly drive. It would also add about an hour to an already long trip as well if you want to do it in one go. However, it's an interesting thought experiment, if it was a 2 lane highway all the way, and I could really get 15 kwhr/ 100 kms, then it would add around an hour. I would only have to charge once, so I could take away a 30 min charge stop, adding only about 30 minutes overall. So I guess an alternative way to do it. I usually take my time on these trips, and don't often do it in one go, so it doesn't bother me if I have to charge more.

@@bydatto39461 I have carefully checked our Atto for range at various speeds on a very long straight stretch of road not far from where I live, so can confirm the 15kWhr at 85kmh. You can even do slightly better at 80kmh. However the road has to be dead flat and no wind. Undulations, slowing, speeding up quickly reduce economy. Actually it's not very different from the diesel ICE I used to economy check. For most cars such as diesel Mercs, 80kmh is a sweet spot for maximum range. An exception in my experience was the Citroen ID19 with sealed underbody and adjustable ride height. It was very economical for a mid sized sedan of that era and achieved maximum range at around 100kmh. In the 1960s I used to drive mine non stop except for refresh, from Adelaide to Sydney with no problems. I used to race my mate on that trip in his e-type. I generally won because he had to make two or three fuel stops. They don't make them like that anymore.

yep well known cold impacts on battery range , well known for me no big deal just be aware
