Smart car This may not be entirely accurate across all driving but in my 2017 Chevy Volt it has a digital KW usage display.

When I am first at the light, I take off with around 75 to 80 KW for just 3 seconds and I'm up to 45MPH and then let up to around 7 to 9 KW to maintain 45 to 50MPH.

When stuck in traffic I take off with the ICE cars pace and see the KW at 32 to 35 for a long duration as it takes the traffic 1/4 mile to get up to 45MPH.

My 2015 Smart ED gauge is harder to accurately depict but follows the same trend ( Floor it to max for 4 seconds to 45MPH then the width of the needle to maintain, VS almost a 25 to 45% pull behind traffic)

If I made a chart graph with the 1/4 mile broken down in time it shows the hard take off/cruise KW/time 15% less than the constant pull.


I'm sure someone with Quantum Physics could elaborate further on this though.

Jeb Baker "Taking off fast pulls max amps for only 5 seconds and then single digit KW to cruise
Taking off slow and average pulls a steady medium load for a 1/4 mile and drains more."

!WOW! I'd love to hear other's to agree with this. This may sound too good to be true, but with peak torque at initial start, this could be true for electrics. Just the opposite of ICE engines.

(My physics is pretty rusty, so if others could jump in I'd appreciate it.)

Smart car I'll chime in from Phoenix AZ.
Winter time here= No climate control needed and 80 mile range driving easy, 75 mile range flooring it off lights beating everyone!
Summer time here = A/C all the time, 65 mile range driving easy, 53 mile range driving hard but trying to conserve range.

After driving my 2017 Chevy Volt for 2 years and my 2015 Smart ED I find that taking off fast and then cruising extends range.
Taking off fast pulls max amps for only 5 seconds and then single digit KW to cruise
Taking off slow and average pulls a steady medium load for a 1/4 mile and drains more.

Spentit I have logged each of my last 441 days using an app called My EV App, Iíve attached some pics of my results but most notable is that spring and fall are almost identical at 114 kilometres while winter at 69 kilometres and summer at 141 kilometres are almost 50% difference of each other. I live in Canada and get some pretty interesting weather throughout the year. I track the temperature in the app so I can quickly graphically see the lows and highs based on the temperatures. The app also tracks what accessories I turn on such as the ac or heater, radio etc so I can see their impact on my range. From my experience with my 2017 ED, road conditions, breaking and take off speed has huge impacts along with of course the normal ac and heater. When I hypermile it Iíve gotten 165 kilometres but youíll notice that my average across all months is just 1.06 kilometres for each 1% of battery which equals 106 kilometres total range, this is in line with the EPA as long as itís based on life averages because seasonally that goes up and down substantially..

RickyM Yes I do only charged 80%. I guess I’ve been so paranoid about battery life and battery failure. I’m an old guy and this will be the last car I buy so I’m just hopping in the last few years. I guess I should just do what you say and charge it to 100%. I figured since I live in such an extremely hot climate in the summer charging 100% might be a bad idea.

sokoloff Ricky - so are you saying it goes down to about 20% from a full charge or from the 80% charge that you have talked about before? I almost never turn my AC on and I get about 80 miles in the summer on a full charge. When I do turn it on, the estimated miles left drops by about 10 miles and pretty much stays there. Hopefully others who use their AC like you do will chime in with their experiences. However, if you are only charging to 80%, take it up to 100%. You're not going to hurt anything.

RickyM I have only had my 2016 smart ed for a few weeks. I live in the Rio Grande Valley in Texas, just two miles from the Mexican border. The summers are usually around 100 everyday so I have to use my air conditioner all the time. It seems like the air conditioning almost sucks more juice than the traction motor itself. Just wondering with air on all the time what kind of mileage do you guys get. I have never ran battery super low but it gets pretty low, like around 20% after driving only 25 to 30 miles. Yikes. Car only has 4700 miles on it. Is that normal or do I have a problem?

kcfoxie End of 2018 I did a dead to full run on my (then) 41k mile 2013 ED, and pulled 78.3 miles out of one charge. Overnight Low: 28, Daytime High: 55. That's my personal best - previously it was 76 miles.

Foolios I get 80 miles on days above 50' generally. It's whenever the temp gets close to 32' that there's a good drop. That onboard battery heater really burns through the watts I guess.
When I see the estimated over 60 I get really cheery. I know it's a great day before I even pull outta the garage.

Similar results here mileage wise, my smart is a 2014
