The Model S just past 21… thousand miles!

Our family is approximately 12-13,000 miles away from our 100,000 miles of EV driving.

It’s so funny, if you read earlier postings on this blog of a little over two years, all the mileage milestone posts that I did. Catching miles on the Model S is harder because of the display screen vs. the manual counter of the Active E. Photographing a display screen is inherently more difficult.

As I was getting in the car yesterday to proceed to drive home, I noticed that I was leaving the office at 21,003 miles.


It’s interesting to note that over the past few weeks, the lifetime rated consumption (Trip A on the pictures) dropped from 311 Wh/mile to 310 Wh/mile on our Model S (meaning we’re just driving more efficiently).

So, after getting home, in traffic,


It just shows how much more efficient I am at driving the car is in traffic than on the open road (the 291 Wh/mile figure). Still not as efficient as I’ve been with the Active E (at 5.0 Miles/kWh (or 200 Wh/mile).

Still gathering Battery Degradation stuff, but did find out that we’re on a D Pack, and that’s at least the latest version reported (as of the writing of this post.)


Definitely on pace to get to at least 24,000 miles by the 1 year anniversary of the car, and that is lower than the Active E. Then again, most of the time that we had the Active E, it was the only EV in the family.

Battery Degradation and Tesla’s “Warranty”

[The original version of this post was written as a response on forum a few days ago.]

All EV batteries degrade. The important thing is to warrant what is acceptable degradation and what is not. Lacking the guidelines sucks, for lack of a better word, but it isn’t fatal. It’s just part of the equation.

We own our two Teslas and I am disturbed by Kevin Sharpe’s Experience, but the published guidelines did say 30% in five years… All this means is caveat emptor.

Our Roadster was already five years old when we bought it, so, I would love to know what I get with the CPO Warranty or what we would get with purchase of the 400 mile upgrade batteries. How long will the car run up to 400 miles.

On Twitter, Nikki Gordon-Bloomfield (@aminorjourney), has postulated that battery packs are the consumable portion of EVs.

Like it or not, she has a valid, and yet expensive point. However, unlike gasoline/petrol we don’t have to replace every time we charge, only as long as the batteries are useful for us. In which case, it’s eventually time to change.

Tesla’s Roadster warranty had defined that in a binary situation, so, if one were to make the case to swap it out under Tesla’s warranty, it can’t be done based on degradation, it is because of a full battery/system failure. This sucks, unfortunately that is what was warranted.

Now the valid question for Model S owners (and guess what, I’m one of those too) is what about our battery packs? Well.. We’ll need to see if degradation is covered.

[This is where new information, or should I say OLD information was posted on the Model S Warranty (including the current “unlimited” Model S warranty) also specifically excludes battery degradation. As was pointed out on both and forums, see page 35 and 36 (pages marked 33 and 34 due to other unumbered pages) of this PDF.

The particular language excerpted from the PDF link above:

“The Battery, like all lithium-ion batteries, will experience gradual energy or power loss with time and
use. Loss of Battery energy or power over time or due to or resulting from Battery usage, is NOT
covered under this Battery Limited Warranty. See your owner documentation for important
information on how to maximize the life and capacity of the Battery.”]

Otherwise, prepare to save for a replacement battery pack in the future. I have always recommended (often in the early years of my blog and in forums) that new EV owners put aside half of what their “fuel” savings aside for the future need to buy a replacement pack IF they do as I do with most of my cars (and that’s keep them for a LONG while) (my hybrid garage has a 2001 BMW X5, my non-green, I have to get to the mountains for Fresh Snow car.)

Guess what, that advice still holds. I’ve lost five miles of rated range from 265 max charge to 260 max charge. Ideal miles lost 3 miles. And I’m less than a year AND over 20,000 miles. However, it must be noted that Tesla delivered the car with greater than 300 miles of ideal miles and I’m just around 299-300 miles ideal now. Yes, it’s hotter in California than the UK and we do have active thermal management, but it’s still the case that degradation happens. I still made it to Barstow, then Vegas on SCs. The car is still awesome, the Roadster is still fun, and Tesla is not perfect. I never thought they were (if BMW i didn’t piss me off as much, I might still have picked up the i3 I ordered.)

[end of almost original forum post.]

After a day of mulling over the lack of battery degradation and comparing the Nissan Warranty, BMW’s match of said warranty and the fact that Tesla’s two competitors include battery degradation, I believe that it is time to call out Tesla and tell them that they need to include battery degradation into the equation. Spell it out. If it is the same specifics as the 2006 Roadster blog post that says 30% after five years, then that’s what it is. It’s not very impressive and I would ask that CPO Roadsters be provided with a modification to this, but that’s at least something. Additionally, AFTER providing such guidance, give us a price on replacement batteries. Nissan gave a $5,500 rate for their cars, why can’t Tesla do it now? With the pending Gigafactory, surely the economics only gets to improve.

C’mon Tesla, be awesome again!

EV Spotting on trips… Hong Kong International Airport and Nissan Leaf

I have a problem.

I’m an EV Geek.

Around May 2014, I took a trip to Malaysia for a deeply personal reason and this trip from Southern California required a stop at Hong Kong Airport. At that time, our layover enroute to Kuala Lumpur was a few hours and after a brutal fourteen hour flight from LAX in last minute booked Economy seats on Cathay Pacific, I was pleasantly awoken by the site of a Nissan Leaf just outside the transfer security for in transit passengers.

I enjoyed it so much that I tweeted the following picture giving credit to EVa Air (pun intended.)

Spotted a Leaf at HKG Airport. Well done EVa Air! #EV

These two particular photos that I shot with my Blackberry had garnered hundreds of hits on my Flickr stream which were still unaccounted for.



That was back in May.

This September, I found myself back in Hong Kong enroute to a more fun reason (vacation) and spotted a fleet of the same colored Leaf by the Taxi Rank at Arrival level.

So, I tweeted the following picture out. We were heading into the city, so it was not the best picture in the world… You basically have to blow the picture up and look in the horizon of the background.

Nissan Leaf fleet charging at Hong Kong International, by the taxi rank

Well, today was payback time. We got to the airport early for our onward journey and I was able to take some cool pictures of the Silver Nissan Leaf EV Fleet in Hong Kong.

So, first set of pictures are from the Lantau Island Taxi Line (across from the lot)




Then, I figured to see if I can actually go to the lot that the EVs park at (then thought I better haul out of here, ’cause it wasn’t really “accessible”)






There are a few more pictures on flickr (just click on any of the pictures and click around…)

Either way… Kudos to Hong Kong International Airport for using Nissan Leafs.

[update from the plane… Spotted outside the window as we were preparing to leave HKG]


So, we got our bill for the second year of Solar usage from SCE.

Year two cumulative Solar PV Bill

It’s been two years since our PTO was approved, and, as opposed to last year, when all we had was the Active E, we pretty much used at LEAST two EVs, if not three EVs over the past year.

In our first year of Solar use, we had a credit. Which, as we found out, we could not claim. Because, it turns out, SCE’s though we’re credited for the production at a $ rate, with net metering, customers are paid out on OVERPRODUCTION and not on the CREDITS earned. What this means is the system has to produce greater kWh of energy than consumed by the end user. If this is the case, the customer is PAID OUT the power times the wholesale rate of production.

Last year, we had a lot of credit as we primarily used energy overnight (at Super Off-Peak) and produced power during the day (the Peak rate). However, we actually used more kWh of energy than we produced. So, even though we had a credit last year, we were not paid out.

This year. We got our Tesla Roadster in the beginning of September, so, when our second year of service started, we were pretty much using TWO EVs. Then we got the Model S, and we were using three EVs during that time until the Active E was turned back in at the end of February. Regardless, the Model S and Roadster consumed energy at a greater rate than the Active E, so we did use more energy than we produced AND totaled a higher amount than we had been credited. Thus, the bill. Even so, at approximately $20 a month for all the driving that we do, and the home power usage. It’s still a win!

Roadster Annual Service… interrupted…

So, the Roadster went into its first Annual Service on September 2nd.  I made sure to communicate my ongoing concerns about the drop in ideal range in standard mode from 186 a year ago (when we picked up the car) to the low of 171 miles before I started doing the conditioning tests (and a high of 175-176 that I’ve had since the beginning of July.)

Today, when I picked up the car (not quite done with some of the work as we’re waiting for parts from Fremont) I was pleasantly surprised to see that the standard charge is now at 183 miles. After one year, a degradation of 3 miles (in about 10,000 miles and one year of CPO use is a LOT more acceptable than the 15 miles that had caused me to raise the alarm last month.)


In the USA, Tesla Roadster Annual Service is $600. So, what do you get for the $600…

1) Fix things… In our case, we had a fracture in an AC line. Waiting on the part, so we’ll have to bring the car back when they get the part. (which is why the service was interrupted.)

2) Replaced a few more things:
Wiper Blade (2001366) 1
BAFFLE, INLET, PEM, DSTAR 1.5 (6002570) 1

3) Tire pressure (then again they ALWAYS do this, it’s mandated in California

4) Got a Model S Standard 60 loaner.

Our loaner for today's Roadster Annual Service. Is an uncommon .@TeslaMotors Brown S 60

5) Some parts were replaced after inspections –

Concern: Part missing following service
Pay Type: Goodwill
Corrections: Power Electronics Module (PEM) – Roadster 1.5
Power Electronics Module (PEM) – Roadster 1.5
Part Quantity
NUT,HEX,M6,ST STL,NYLOC (2000821) 4
Parts Replaced or Added
Corrections: Soft Top Assembly
Soft Top Assembly
Part Quantity
SCR, CABLE TO SOFT TOP (6002461) 4

6) We complained of some “weird” noises…

Concern: Customer states: Vehicle noisy while driving – noise from rear
Pay Type: Goodwill
Corrections: Upright – Suspension – Rear – LH
removed and replaced upper control arm- left rear bushings
Part Quantity
+INTERLEAF (2001482)
Parts Replaced or Added

7) The rear tires are worn… After 10,000 miles, looks like it’s time to replace the rear tires… Have to do it when we get back. Though I told them to replace the tires, there is still some wear left and we’ll do it when the part that we’re waiting for is ready.

8) Also waiting for a replacement driver side door sill that has a crack. So that’s something that we need to wait for as well.

9) Pulling logs seemed to have gotten stuck. So, the tech freed it up so that I can pull logs again.

In all, I’m very happy that after the battery bleed test and whatever else the technician did, we’re back over 180 miles for a full standard charge. I count that as a win.

It’s great to get an explanation on the delays in Roadster parts. In my case, some parts were readily available and fixed those things, but others are delayed because, per the Service Advisor, the Warehouse that houses a majority of Roadster parts is being moved. So, we’re now waiting for the move to complete so they can get the parts to us. Hopefully this means next week.

So, all the parts we’re waiting for are covered by the bumper to bumper CPO warranty, with the exception of the tires. They’re not the cheapest in the world, but along the same lines as other “high performance” tires.

What else will Tesla give you? Free Wi-Fi of course.

I spend a lot of time at Tesla facilities…  Whether it’s a supercharger, a Tesla Store, or Tesla Service, I tend to like to be at Tesla facilities.

Yes, I’m obsessed.  Either way, what else do you get for free at Tesla, well, their guest Wi-Fi is free and the password is the super secure “abcd123456”.

So, if you find yourself supercharging at Hawthorne, CA or at a Tesla Service Center, just remember to connect to the “Tesla Guest” or “Tesla Motors Guest” network and use that super-secure password.

Now, remember, it’s a shared wi-fi network, so be warned, be careful, and be safe.  Use some sort of protection when connecting.

Here’s my Model S at a late night stop on the way home from Hawthorne on our first Tesla Weekend… using the free wi-fi at Hawthorne Design Center/Supercharger.
