    2009 1.5 standard Roadster - For the longest time now, seems like the best range I've seen off the batter after a charge is 196-197 miles in standard mode. The other day I had to drive it and really run the range down to the last 19 miles. I swung by my usual charging spot (Blink station) to "fill the tank". I came back 7 hours later to see 212 miles of range, wow! It's been at least year since I've seen that. 95% of the time, it's plugged into a 115VAC outlet. It's only when I suck up a good chunk of range that I use a 30amp Blink station which usually only gives 186 miles of range on standard mode before it shuts off.

    Anyone experience anything like this before? I did some searching, but didn't find anything like this.

    Do you know how long you got to the car after if finished charging? The pack needs 15-30 minutes to balance, and after it balances it settles down on its real ideal miles. I get anywhere from 194 to 213 ideal miles in my standard mode charges depending on my amps (slower = higher) but after it completes its balancing always lands down to 182 ideal miles which is very accurate and consistent. That "right after charge" number is not a real useful number but rather misleading. I don't know if the model - s handles this better, but I'd think you could save the last 5 - 10 charges and give the user that number when its topping off the pack. Then once the pack balances its not a drastic change and buffers the misleading ideal miles with an average ideal miles the driver is use to seeing up/down to the balanced ideal miles. The delta would be smaller.

    I'm really trying to wonder why the pack is taking such a high SOC on these charges, 94% when I hit 213 ideal miles. I don't know if its trying to pull up some weak bricks/sheets or what Tesla has going on behind the scenes.

    I know what wiztecy is saying about false range readings after charging. There is 1.2 miles to drive from the Blink station back home, it only dropped to 210 miles when I pulled in the garage which is pretty normal (dropping only 2 miles of range). Plugged into the 115VAC that I normally use, I've noticed it's back to its 195 mile range again. It was probably nothing and I know these batteries don't develop memory cycles and don't get better with time or use. Just caught me off guard when I came back expecting to see the usual 186-187 miles of range and Blink saying "All done!" and seeing 212 and "All done!". Bizarre.

    "Do you know how long you got to the car after if finished charging?"

    Probably only about 15 minutes after it shut off.

    If I did this right, there should be a picture of today's charge on a 30amp Blink station. 202 miles of real range. Pretty neat! I know it shouldn't matter, but I'm starting to think the deep cycling of the battery has removed a little bit of the memory charging.

    I've never seen anything like that! Please do us a favor and submit your battery data to the two roadster battery studies. It only takes a minute and will benefit all of us.

    This one looks at the logs and has a lot of data analysis posted here on TMC:
    Roadster-Owner-Based-Study-of-Battery-Pack-Capacity-Over-Time

    This one doesn't require pulling logs and it's real easy to submit your data:
    Plug-In-America-Tesla-Roadster-Survey

    Thanks!

    Will do! Next time out on the road will be Monday. I'll pull logs and post. - Dan
