Separate names with a comma.
That's why I think it's not balance. The debug screen had stopped balancing at full range charge. Then I topped off and let it finish balancing...
The slope of the lines is -0.428 Ah/month for the old battery (measuring from the peak after the rebalance for the replacement battery in Oct '11...
Here's a better cropped version of the first graph. [ATTACH]
For reference, here's the same graph for the lifetime of the car. The bump up around April 2011 is when I had a battery replacement, which took a...
I did what I should have done in the first place and pulled the logs and looked at the CAC over time. It's more-or-less going down linearly,...
How many miles have you put on the new battery? How often have you range charged it?
1.5s seem to take less time. At least, folks with them in my area who ordered after me got their upgrades first.
I'm pretty sure that it's balanced. I drive it most days and standard charge, so it sits with a full standard charge for hours each day. I also...
I got my 3.0 upgrade in early October, so it's been about 4 months. In that time, I've put roughly 6K miles on the battery. When I first got it,...
Tom Saxton did a very nice survey for Plug In America, the primary conclusion of which was that the only significant factor effecting Roadster...
Oh, and it does say SOC = 97%, and 77.36kWh/0.97 = 79.75kWh, so I guess we can give them credit for 80kWh.
In terms of bad stuff in the car, I've got you all beat. A couple of weeks after I got my Roadster the local owners had a group drive. I took my...
The battery was mostly empty, and it was certainly the PEM temp that was limiting. I don't remember the actual temp off the top of my head, but...
Here's a picture of the ESS diagnostic screen with my fully charged, new 3.0 battery. Sorry for the awful quality. It says CAC 215.20 Ah, kWhr...
You should come visit Seattle. There was another Roadster in the grocery store parking lot this weekend. And it's not like the Roadster has all...
Everything you describe sounds perfectly normal to me. I charge at 220v 40A, and usually at least the fan runs, and it's very loud. I've noticed...
I think that trying to predict wait times by looking at historical times is probably not going to work. It seems like what's happening is that...
No, it was a 1.8L 914-4. I bought it fresh out of college and didn't have much money. Wikipedia claims that it had 63kW and 12.0s 0-100km/hr,...
The guy next to me was parked into my parking spot. So, I'll give the benefit of the doubt to F=ma and assume that he was forced into it like I was.
[ATTACH] It doesn't make me look that small, but it does make me look like I'm not the only geeky person around.
The 3.0 battery behaves differently in Standard Mode than the earlier versions did. Full charge range charge is about 344 miles. Full standard...
You get about 1KW into the battery (depending on how much fan/cooling/whatever else you need), so from all the way empty to all the way full it...
So charge in Range mode and drive in Standard mode. You get the extra charge without the power limit. That's what I usually do. Then, if you...
Did anyone else notice that at the end of the self-driving demo video that Tesla put out (around 2:01) that there's an orange Roadster (Elise?)...
In this case, I think it was Lotus that made it possible, not anything to do with being electric.
On the other hand, in the unlikely case that it's real, 84K miles is no big deal. The main thing to check for is how much charge the battery will...
Yeah, I think that's about what I remember, too. My 243 kW was in similar conditions: standard charge (which is more like 80% than 90% with the...
I noticed that with the 3.0 upgrade that the little power meter on the VDS is showing as much as 243 kW (about 325) when accelerating in...
You have to be a little bit careful about this assumption. During the all-too-frequent times when my TPMS is failing, it tends to pop up the...
I don't think that it synchronizes time at all. At least, mine periodically needs to be reset, and certainly has no idea about daylight savings...
On the Roadster end, be sure to put the cable into the car, turn it clockwise until it won't turn anymore and then push the switch that will then...
That looks like my car with the other wheels and two fewer digits on the odometer. :-)
Good point. It's not just the badge, it's the whole front end.
The old Tesla shield logo (from my Roadster the day I got it).
Tesla Shield by bolosky posted Oct 4, 2016 at 7:07 PMSo why does it have the new-style T badge on the hood rather than the shield? I have #670...
Being close to replacing the rear tires is true even if you have brand new rear tires. :-) Without a doubt, I spend more on tires than on...
A number of years ago I hurt my right shoulder through a bunch of things like playing softball and hang gliding. The net of it was that I had to...
Since we're telling stories about making money selling cars, I'll push this just a little more off topic and tell mine. This is *completely*...
I had a 1975 Porsche 914. A tiny, two door mid-engine roadster with a frunk. It was light and because of the mid-engine, it handled amazingly...
Yes, it knows where it is by using the GPS. What you're seeing is the designed behavior. Welcome to 2008. :-)
#670 is 17 Aug 2009 (so I guess I'm a day late posting this :-))
Tesla confirmed that the issue is that they don't have parts for 2.0 upgrades. They didn't say, but I assume what's happening is that they don't...
I just looked at the old thread about 3.0 order dates, and noticed that Dave placed his order on October 28, while I placed mine on September 11...
I got the car back today. Tesla didn't charge me for the second service visit for the fan problem, which is very nice. I have to say that while...
The latest on my car is that the problem is a pin on a circuit board in the PEM that had too much play in it (read: was loose) that was messing up...
My Roadster's reliability problems are really starting to get to me. I think it's been in the shop at least three months out of the past year,...
To be clear, I've never had any problems with overheating except for on the track, and even on the track it didn't damage anything, it just caused...
I got it to overheat on a go kart track where I never got above about 70, and that only for a tiny fraction of the time. It's essentially all...
I liked your analysis. You mostly nailed it. The one thing that you missed is that in addition to running out of battery capacity, the Roadster...
