New Battery Connections

This blog post is part 2 of a  3 part series of completely unrelated incidents that just happened in quick succession.

About four miles away from home, my car issued the second warning message of 2017:

Acceleration Reduced  Contact Tesla Service When Convenient

Fortunately, the issue did not require me to stop immediately, and I felt comfortable driving home.  When I contacted Tesla Roadside Assistance, I was transferred to Tesla Service.

When Tesla Service contacted me, a bit to my surprise I was told not to continue driving the car.  Instead of driving the relatively short distance to the closest service center, they wanted to tow my car.  Fortunately in my area, you can have your Tesla towed by appointment.  I decided to delay it a day to a more convenient time.

The local towing operation is now very familiar with Teslas and did the operation quickly and efficiently.  There are only two things unusual about towing a Tesla:  setting the tow mode on the car, and secondly using a two pronged vs one prong cable.

Two Points Required to Tow a Tesla

This problem with my car had to do with the connectors to the main battery.  Within two days, the service department replaced the power switches with the latest generation parts,  replaced the HV Blanket, and removed some corrosion.   The descriptions listed in the invoice are:

“Replaced power switches with latest generation parts as necessary”

“Replaced HV Blanket with updated part”

“Retrofit 2nd Generation Battery Blanket and Remove Corrosion From Battery Cover”

Here is the list of parts that were replaced:

1 BUSBAR,OUTPUT,POS,HVBAT,MDLS (1048113-00-A)

1 BUSBAR,OUTPUT,NEG,HVBAT,MDLS (1048111-00-A)

2 SCREW,M8-1.25X19,HEX,BARSS,PATCH WITH WASHERS (1004392-00-B)

1 FIELD KIT PYRO FUSE PACK 1.0 1.5 (1089619-00-B)

1 FIELD CONTRACTOR KIT W/O FUSE – PACK 1.0 1.5 (1084515-00-B)

1 BLANKET, CERAMIC,HV BATTERY,MDLS (1006466-00-F)

8 TALL HEAD HOLLOW FASTENER FOR BIW MOUNTING SLEEVES WITH VHB SEAL (1018552-00B)

2 SHORT HEAD PACK SPACER FASTENER ASSEMBLY (1018551-00-B)

1 BATTERY RECYCLING WARNING LABEL (1015713-00-B)

In general this issue was not particularly painful, I was unable to drive my car for four days (including over a weekend).  The problem could have been very inconvenient if I was away from home or on a road trip.

The cost was covered by my warranty coverage.  However, I am not sure if the cost was covered by my extended warranty or the battery warranty as the language on the Tesla website is not very detailed.

12 Volt Battery Ranger Service

12V Battery Needs Service

After a period of calm and low mileage driving in recent months, I have unfortunately encountered a few problems with my Tesla.  This blog post will be a 3 part series of completely unrelated incidents that just happened in quick succession.

I was innocently driving along and encountered a warning on my dash:

I have had my battery replaced only once before back in early 2014 when my car was in for service.  The nice part about the 12 Volt Battery replacement is that it is not an urgent matter.  If the car needs to do so, it might shut down some auxiliary electronics, but you can safely drive around for a period of time.

Ranger Service

What was also very nice, is that for no additional charge, if you live within a 10 mile radius of my service center, a ranger will come to your location.

The battery change took about 20 minutes, and just out of curiosity I watched the process.  The process is only a bit slow because there is quite a lot of screws and parts to remove.  I asked the ranger, and he said the Model X is not any more serviceable than the Model S.  Hopefully the model 3 designers will consider serviceability a little more during the design process.

This ranger service also deals with tire issues and door handles, things that can be accomplished easily at remote locations.  This service is a win win for Tesla and the customer base.  Instead of the hassle for the owner to drive to the service center and get a ride to home or work, the ranger can easily just move around town and address any issues at the owners convenience.  I am not sure if this service is available in all locations, but it worked great for replacing the battery after about 45,000 miles and 3 years.

Climate Change and the Election

The end of the 2016 was a challenging one for most Californians.  People have been in various states of shock, anger, disbelief, and sadness. During the fall I took a Stanford Continuing Studies class about the election.  I have a friend who is a political nut, and I thought the class would be interesting and had many renowned speakers.  David Plouffe, the campaign manager for Barack Obama’s successful 2008 presidential campaign, spoke to the class and said that he was 100% sure that Clinton would win.   So I believed an expert and was shocked when Clinton lost.

Since the election, I have chosen not to blog about some of the more mundane aspects surrounding owning a Tesla waiting to summarize my thoughts about this last month and a half first in this post.  Although politics is a challenging topic to discuss, I believe the current state of the U.S. is very relevant to both a healthy green environment and the long term success of electric cars including Tesla.  I won’t discuss many of the other horrific things that have been said about women and minorities during the election, but just focus in on our environment.

Elites and Technology Elites

During the aftermath of the election, many pundits spoke of the movement being a revolution against the elites.  Income inequality is higher than it has been since the 1920s, and the unorganized Occupy movement a few years ago tried to address the growing discrepancy.

The Industrial Revolution shifted society from an agricultural and handcraft society to a machine driven one.  The Technological Revolution has shifted society from a machine driven one to a highly automated one.  Many people who formerly worked in machine driven factories have lost their jobs to robots.  Additionally because of the ability to communicate globally, we have become a global not national economy, and jobs have moved to places with lower cost of labor.

My career had a direct affect on changing our society.  In Silicon Valley (outside of the defense industry) we always believed that what we were creating was going to be useful and not harmful for people.  Yes, some early chip companies had problems during the manufacturing process that resulted in some major toxic Superfund sites.  But by and large, the technologies we created have freed people up from mundane tasks and have allowed us to communicate in ways that we could not have imagined a century ago.  The large majority of people would be very upset if they no longer had the ability to use the internet or their smart phone.

I do not believe most technological elites realized the deep impact these changes had on some parts of the country.  Looking forward, the biggest change technology could be self driving vehicles.  3.5 Million people are truck drivers today.  If all these jobs were automated in a short period of time, how will these truckers be able to find jobs with comparable incomes?

The Environment and Global Warming

The reason I started this blog was because I care about the environment deeply.  By sharing my experience driving an electric car, I could encourage other people to make similar purchases.  My solar panels on my home are ten years old, and according to my calculations I have recovered all my upfront costs including considering the opportunity cost of the investment.  So my electricity at this point is completely free for both my house and Tesla.

Scientific evidence for warming of the climate system is unequivocal.

– Intergovernmental Panel on Climate Change

I am baffled by how many people in the U.S. still do not believe that climate change is occurring and that it is man made.  I have a friend who is a scientist by trade, who watches Fox news and still refutes the fact that global warming is man made.  We had a long civilized discussion about it and now matter what facts he is presented, his only argument is “There are just so many factors that could cause these changes.”  In the end I concluded that talking to him about any facts was futile and he has a deep embedded story that he believed – akin to a religious or non-religious belief.  I also think if he admitted to the reality of climate change, his sense of personal story and ego would crumble.

Trump selected Scott Pruitt, the attorney general of the oil and gas-intensive state of Oklahoma, to head the Environmental Protection Agency (EPA).  Pruitt has fought regulations on our environment and even defended ExxonMobil when it tried to deny climate change and disavow the oil companies’ evidence.  He also stated “The American people are tired of seeing billions of dollars drained from our economy due to unnecessary EPA regulations, and I intend to run this agency in a way that fosters both responsible protection of the environment and freedom for American businesses.”

This quote is incorrect, a 2016 survey of the world’s major economies also found that strict environmental policies improved, rather than handicapped, competitiveness in the international market according to the growing consensus among Organization for Economic Cooperation and Development (OECD) economists.  For example, California has the strictest environmental regulations in the country and enjoys the most robust economy in the U.S.

How the environment became a political issue is bizarre.  Richard Nixon created the EPA, the Clean Water Act and the Endangered Species Act, and George W. Bush signed the extension of the Clean Air Act.  The environment and the future of our planet should not be a political issue.

Conclusion

I am very saddened that my country elected a racist, sexist person without compassion who does not care about the environment.  I will do whatever I can to help make America a good place for everyone not just rich white men.

How does the election impact Tesla and the environment? I think Tesla does need to consider the impact of autonomous vehicles on those who depend upon driving as the source of our income.

My far my biggest fear is climate change as the U.S. needs to be the leader in solving global warming, and if we don’t act fast the problems may be irreversible.

Supercharger Fees

Several superchargers in busy areas in California have had long waits such as San Mateo, Burbank, and San Juan Capistrano.  A year and a half ago Elon gave a vague statement about supercharging that was never clarified by Tesla.  Many owners have worried about the huge numbers of Model 3s clogging the supercharger network.  Finally today Tesla has announced a new supercharging policy for cars ordered in 2017 and later.

For Teslas ordered after January 1, 2017, 400 kWh of free Supercharging credits (roughly 1,000 miles) will be included annually so that all owners can continue to enjoy free Supercharging during travel. Beyond that, there will be a small fee to Supercharge which will be charged incrementally and cost less than the price of filling up a comparable gas car.

our Supercharger Network will never be a profit center.

These changes will not impact current owners or any new Teslas ordered before January 1, 2017, as long as delivery is taken before April 1, 2017.

I am glad Tesla finally made a decision about the future of supercharging. Some speculation exists that the older cars have now increased in value, but newer cars can still use the superchargers for a fee.  On long trips, I suspect newer drivers may choose more often to frequent hotels with destination chargers or utilize more public chargers.  The greatest potential impact may be renters who wish to buy a Tesla, and now have to consider the cost of charging with their Model 3.

One thousand miles is not a lot of free Supercharging credit.  A good percentage of my miles on my Tesla are supercharged.  But I’m in a unique (and fortunate) circumstance with no commute and free time to travel when and where I please.  I will be very curious what the actual fee is to supercharge a car and add say 50KWh.

Battery Swap – Closed

Looks like the battery swap station at Harris Ranch in Coalinga, CA is closed.  I heard a rumor that it was closed, inquired about availability, and received the following response:

Presently the Battery Swap Program is not accepting any new requests for appointments.

Because you had to schedule an appointment in advance,  the battery swap was not convenient.  Since my first and only swap experience, I have used the superchargers at Harris Ranch at probably six more times but never could schedule or plan another swap.  I doubt the station will be missed.

 

 

Solar Roof Tiles

Tesla’s latest event was labeled as Powerwall 2 but the more interesting part of the event was when Elon announced a set of solar tiles for roofs.

glasstile.jpg

These new solar tiles are available in a few styles including a Tuscan style one in an orange color and more modern grey tile ones shown above.  All the styles are made of glass that are stronger than conventional roof tiles.  Elon claimed that installing or replacing a roof would be cheaper with these Solar City tiles than a conventional roof!

Elon also announced Powerwall 2 with twice as much energy storage than the first iteration, along with PowerPack 2 for the commercial market.

Powerpack.jpg

The goal is to have solar on your roof, a Powerwall in your garage, and a Tesla in your driveway.

trifecta.jpg

I have already had solar on my house for 10 years, and I actually have a flat roof where you cannot even see the panels.   My house is quite unusual, but if I had a conventional house without solar I would seriously consider these new panels.  I wonder if only Solar City can install them or can you buy them at retail stores like Home Depot?

Part of the timing of this event was clearly to influence the vote on the merger. My small number of Tesla shares will in no way influence the outcome, but I have not yet decided how to vote.

v8 USB Media Player Bug List

Update 10/25/2016:  Another owner extensively tested the USB media formats and ID3 tagging with v8.  The very detailed report is available on TMC.

The following post was written by a guest blogger, who is known as supratachophobia on on the Tesla Motors Club Forum (TMC) and lead the effort to bring back the NEMA 14-30 adapter.  Working with the direct feedback of dozens of other owners, supratachophobia compiled an extensive and prioritized list of both bugs and enhancements of the media player as it pertains to USB audio. Content compiled, thoughts composed, and article sent in by supratachophobia, edited by Owner, which is my TMC handle.

 

Introduction

First, let me say that v8 is a welcome addition to the ongoing software development process in the S (and soon to be the X). The forums all have positive comments in general on autopilot tweaks, additional features, and the overall (but definitely not all) interface improvements. While the general design of the overhauled media interface is an improvement from v7, it seems to be slanted towards those users who primarily stream their music. As such, many of the functions for USB playback have been partially broken or made more difficult to use, particularly when driving. As a result, there are questions as to whether the testing that was done with v8 had a proper sample of those owners that use USB playback as their primary choice for audio.

The USB audio playback is a very popular feature, especially for audiophiles, because it generally produces the highest quality listening experience. In fact, those that purchased the Ultra High Fidelity Sound package did so knowing that they would be playing a large collection (many thousand tracks in fact) of high-quality/lossless audio formats from USB in order that they be able enjoy the highest possible sound fidelity. Tesla works with a broad range of music formats: from the more common MP3, MP4 and AAC (without DRM), as well as formats such as FLAC, AIFF, WAV, WMA and lossless WMA. (Note – we at TMC are not clear what is officially supported by Tesla and would like some clarification).

Streaming radio uses compressed MP3, and streaming Bluetooth compresses both high bitrate MP3 and FLAC data across the connection. Under some circumstances, iPhone AAC may be able to bypass this compression. But only through USB can the audio be lossless and at its highest quality. Many audiophile owners have very large collections (1k – 10k) of tracks on their USB, and 7.1 worked much better for these large libraries. For me personally, USB audio playback was in my list of top 5 reasons for purchasing 2 of these cars.

TMC Forum Discussions

TMC has four large forum discussions currently active (those are just under Model S, there are more under Model X) with regards to how the car now handles USB audio and the lack of testing this particular functionality in the Media app received in the new v8 rollout. Please note, that many of the concerns cataloged below were features that functioned with little to no issue in v7.

As of this writing, the TMC threads have the following number of posts and views:

250+ Posts / 6,000+ Views: Comprehensive USB Bug List

100+ Posts / 3,400+ Views: Media player in 8.0 actually got worse (for local music)

200+ Posts / 7,200+ Views: 8.0 Music Player Unusable

Main v8 Thread / Over 3,500 posts and 265,000+ views so far, with USB audio problems dominating the discussion: Firmware 8.0

8.0 USB Media Player Bug List

The following is a list of specific bugs that have been detected, with as much detail as our end-user base could glean from real-world usage. We have prioritized the list as best as possible in the order presented below.

  1. The 8.0 Media player no longer includes a letter list from A-Z allowing you to search through song, album or artist lists by the first letter. Now the media player shows everything in one gigantic list. Trying to scroll through a list of thousands of items is very dangerous when driving, and does not actually work in practice, see issue 2.
  2. When scrolling a USB list view with several pages of items, the scrolling feature does not work as expected. Any attempt at repeated scrolling gestures are interpreted as a click into a folder. When you try to back out of that, or any folder, the interface takes you to the top of the previous list, instead of the point in the list where you entered.
  3. Album tracks are being played alphabetically instead of by track number. This playback is unpleasant when listening to an album, but a horrible problem when listening to audiobooks.
  4. “Search Anything” does not search anything, it searches everything except USB media. Please allow search (both via text entry and voice) to include USB media and a priority option to USB playback (if results are found) at the top of the results list. (Rumored to have been resolved in 8.21 – thank you)
  5. When media is paused, the system should note the point in the recording. When resuming play, the system should start from that point. Today, when the driver leaves/returns to the car or resumes playback, the result is unpredictable. Sometimes the track will reset to the beginning, which is especially annoying when listening to an audiobook or podcast. Sometimes when the player is on pause, and the driver re-enters the car, the media turns itself on again.
  6. The shuffle feature “on” is not predictable or persistent and turns off at random times. (Changing between USB sources, and during entry/exit of the vehicle.)
  7. The shuffle feature itself does not properly randomize. The same sets of songs are repeated in the same order when shuffle is engaged/re-engaged.
  8. When looking at a list of items under an artist name or browsing a folder, the list view is a simple alphabetical display of all items intermixed, such as when using a UNIX ‘ls’ command. In v7, the system always had albums, which are folders, at the top of the list followed by any single tracks.
  9. The car needs to maintain Track Title, Disc, Album Artist, and Album Title in all the lists, presentations, and sorts to avoid difficulties with “Greatest Hits”, multi-disc audiobooks, and boxed multi-disc sets.
  10. Some scans take an abnormal amount of time. The forums have no clear conclusion what causes this problem: read speed of USB media, number of tracks, or size of data. The current workaround is to turn off power-saving mode in the car. Some owners report the USB sticks with 6,000 or more tracks now take two hours to get to 80% complete.
  11. Sometimes the Bass, Mid, and Treble settings are not saved overnight. Again, TMC is unsure if the problem is triggered by changing USB audio sources. We were wondering if the intended feature was to allow different equalizer settings for audio types on different USB sources. For example, audiobooks would have a different profile for music. If so, we would welcome this feature, but would like it documented in the release notes.
  12. Spaces in the USB volume name are represented by the ASCII value “\x20” and not a blank space. For example “Fix These Bugs Please” is written as “Fix\x20These\x20\Bugs\x20Please”.
  13. Album Art is still broken for some users. In this area, we would really like some clear documentation of what is supported. Some owners rarely see their album art for unknown reasons. For an album with multiple artists, the media player should display the album art if the song is not populated.

Enhancement Requests

  1. The ability to find new matching music (and add it as the next track in the queue) based upon elements from the current song being played. For example if Michael Jackson’s Thriller is playing the track Billie Jean, you could tap on the ‘artist’. The media player would then find a different track, by Michael Jackson, and make it the next track to play. Now if you pressed the text of the ‘album’ name, Thriller, then the next song to be queued would be from that album. And finally, if something like the song Smooth Criminal was playing, tapping the song title would go and find that song by another artist, for example, the version done by Alien Ant Farm.
  2. The ability to play an entire hierarchical folder. The first entry inside every folder should be a button option to play everything in that folder including loose items and all items in folders within folders. This feature would be very useful for folders that include sub-genres.
  3. The ability to bookmark a set of exact places in an audio track for resuming later. Bookmarking is a critical feature for both podcasts and audiobooks played through USB. Currently it is very challenging to try to find the correct space in an hour long or more podcast to resume listening. This feature would be able to store at minimum of 3-5 bookmarks and be found next to the “Favorites” and “Recent” tabs. The selection of a bookmark would take you not only back to the timestamp, but also to the “album” so that the book could resume at the next track. The shuffle status, on or off, should be restored to what it was as well, when the bookmark was made.
  4. When displaying a set of recently played items, this list should remember the playlist context of that item. For example, playing song 5 from album X, selecting song 5 from the recent list should remember that the person was listening to album X in its entirety. This mechanism should also work when song 5 was part of a playlist entitled “Foggy Morning Drive”, and pick up playing the rest of the music on the playlist “Foggy Morning Drive”.
  5. Some owners would like support for the m3u format, which has always been the most popular playlist format. M3u is currently recognized by every major media player on the market, including almost every other vehicle that does MP3 playback.
  6. The support of gapless playback for lossless audio formats (AAC and FLAC).

8.0 USB Improvements

  1. We generally really like the simplistic aspects of the media interface and see it as an improvement over 7.1.
  2. The album artwork from the ID3 tag is displayed most of the time. But we are curious what the size limitation is here as many owners are having mixed results.
  3. The name of the USB volumes are now recognized and displayed.

Video

I also made a video of my personal likes from the use of an Empeg for 12 years. I found a lot of it’s functions to be invaluable when listening to MP3 audio in the car.

Conclusions

The 8.0 software seems to be a nicer interface for playing music. The dual column scrolling and the Now Playing screen utilize the screen real-estate much better and more completely. But there are several opportunities to improve in the areas where USB playback challenges were left untouched or newly introduced. We hope these will be quickly addressed by Tesla seeing that with the ever-growing ownership base, more and more will come to use USB playback as their primary audio source as well.
