Bob Denman Okay... What is the towing capacity of a Smart?

The Tesla Model 3 battery is bigger than your smart ED/EQ . . .

Tesla has managed to pack the 4,416 cylinder cells (2170) in to four modules that weigh around 1054 lbs / 478 KGs combined.

Bob Denman I wonder what the range would be; if you could fit the Tesla battery and charger system to the Smart?

sokoloff Upper 80's estimated range on both of mine in the summer, but I almost never use the AC and I also play the game of seeing how much range I can get. Winter time usually is never lower than 70 miles. I have found those estimates to be pretty consistent with both real life and my State of Charge indicator.

MineCooky The range my smart is giving me varies quiet a bit. Honestly I'm not even cheching it anymore. When I start the car I just check the soc and that's it.

Smart car Update on my minimum range.
Here in HOT SUNNY Phoenix now with the A/C on 38 miles range! That A/C IS AN ENERGY SUCKER!!!
I get in the car, 63 miles estimated, click on the A/C and it drops to 40, turn off the A/C and it goes back to 63.

I'm glad I don't use heat! it runs the range down in the low 30's for estimated range!

sokoloff My coupe also showed the 90 mile projected range yesterday after I drove it all day. Got to say though that the coupe is my wife's daily driver and she typically gets in the mid-70's on routine charges. I usually get in the mid to high 80's. We have very different driving styles. I take it as a challenge to see how much range I can get. I watch ahead of me and will usually drop it in to "N" when I see a stop/red light coming ahead. The free wheeling distance is amazing. Of course I watch my tail closely too to make sure that side of me is safe. If there isn't enough time and space to use "N," then I'll let the car do its own regen and use the actual brake as late as is safe. I will also pop it into "N" if it is safe to do going down hills. My speed rarely goes above 55 mph. I take the "country" roads instead of the highways when I have the chance.

Same here - the highest range I have ever seen projected has been about 73 or 74 miles. The longest distance we have continuously driven on one charge has been about 90 miles with about 15% SOC remaining.

Repeatedly using the battery to a lower SOC and then charging it back to 100% seems to result in a "fuller" charge in that regen is disabled for a longer period and the SOC hugs the 100% level for longer. We can consistently get to 80% having driven 20 or more miles but the interval from 80% down to 70% always goes quickly - even with identical driving conditions in a single continuous drive, that 10% interval never nets us more than 7 or 8 miles driven. The SOC seems fairly linear from there down towards at least the 20% mark, which is as low as we normally take it.

Also, if we drive it continuously from 100% down to somewhere in the middle 70% range and park it for some time, the SOC will always drop a few percent on the next restart. This doesn't happen to nearly the same degree elsewhere in the charge spectrum, and how much it drops when turned off varies depending on how quickly the battery has been discharged from 100% down to that point.

There's probably some rebalancing of cells that occurs at that point, or some readjustment of displayed SOC versus actual SOC. Or maybe the voltage profile of the battery changes as the cells rest/rebalance after continuous use to that point. Whatever it is, it is very repeatable.

Your MY14 451 ED is "rated" at 68 miles but it appears that your "city" driving is giving you some pretty good results!

As for software version - without M-B service records from the previous owner the only software information lies with your "local" smart Center and THEIR PROPRIETARY diagnostic equipment.

If you have a smart Center nearby it may be prudent to take it in and make sure all updates are in place as we suspicion that some HV failures may have been a software issue???
