Thank you for the report on an original Roadster pack. I'm glad to hear it's being enjoyed as a daily driver. While I agree that getting mile-for-mile on ideal range requires a deliberate effort to drive efficiently in favorable conditions, I don't think using a homophobic slur is a good way to...

Hi Drew, The "help text" is what you get if you run the my parser with no arguments. It includes a list of all the command line options, the codes I use for the various record types, and some example commands. VMSParser The charge history is only available in the transient section of the log...

Have you added your vehicle to the Plug In America Roadster survey? Getting current data there would be helpful to the community. There are tables and charts on the site, and all of the data (except personally identifying information like email addresses and non-US postal codes) can be...

I believe Martin Eberhard's blog post, A Bit About Batteries, is still the best reference for understanding the Roadster's original battery pack. I've never heard of a benefit to lithium ion chemistry for charging to a higher SOC. I don't know about rumors that Tesla does a range mode charge as...

I have a hard time believing it's bad for the battery not to range mode charge. I do believe the car needs to see a range mode charge, and discharge down to maybe 20% or so, for it to really know what the battery's capacity is. The longer it's been since a range mode charge, the less reliable...

No problem, it was a reasonable theory.

The -j option was created early on, before I starting parsing the vmslog file in place within the tar file. The idea is to write out a single flat file with all of the log entries from multiple files, but I don't know if it still works, or ever worked. The code that fixes the dates doesn't know...

You have to run VMSParser from the terminal (macOS) or command prompt (Windows). If you just run it from the Finder/Explorer (by double-clicking for example) it will do what you describe: open a temporary window, execute the command with no arguments so it spews out the default help text and...

Good point! Charging at 120V takes about 50% more energy than 240V/32A. Tesla Roadster Charging Rates and Efficiency - Tom Saxton's Blog

When charging at 120V, the coolant pump runs for a longer period of time. Some believe this leads to the coolant pump failing sooner or more often. It's probably not an issue if you're leaving the car parked for the winter, but I believe there's a small increased maintenance cost for replacing...

Follow this link: Battery Survey « Plug In America Then just fill in the blanks. The page explains where to find the information needed, but feel free to message me with any questions. If you're reading your CAC, you're already ahead of the game, especially for a sixth grader! :)

It would be helpful to get your stats on the Roadster survey. That will let you see how your car compares to others and let others get more info on the performance of the new battery packs.

I have a couple of Roadster HPWCs I could be talked into selling. They are the original Tesla versions, made prior to the ClipperCreek version. Unlike the ClipperCreek versions, they have an easy way to set the maximum charge rate. Of course, you can always set the charge rate at a given...

I agree that we need a lot more EVs, but total US sales is over 1 million, almost 1.5.

You can see lots of data on the Roadster battery survey. If you own a Roadster, please share your experience, or use the update form if you're reported before. One thing to keep in mind: the car can't know the pack's capacity if it hasn't seen it charge and discharge recently. The longer the...
