Tesla Model S EV Annex Carbon Fiber Upgrade

Originally posted on CleanTechnica

The good folks over at EV Annex have the shelves stocked deep with custom designed and built Tesla accessories like the Center Console Insert and the Cubby Compartment that really fill in some the functionality gaps. They also have a wide variety of custom designed and built accessories that offer a different take on the design aesthetic of the Model S and X.

Carbon Fiber Blade Spoiler

They sent a few of their carbon fiber accent items over to spruce up the exterior of my Model S. Unfortunately, I’m no professional installer but thankfully, all of the interior products I have tested out to date have been easy and straightforward to install. This time around, I was happy to find that their exterior products follow suit, while adding nice touches of class to the exterior of the Model S — a challenging feat considering how great it looks already.

For starters, adding the EV Annex Blade Spoiler adds an amazing pop of class to the car and does so at a much more approachable price point of just $589 compared to the Tesla version which will set you back a staggering $1500. Granted, the Tesla version includes installation, but even if professionally installed, the EV Annex version comes in at a much lower price point and with quality that is nearly indistinguishable from OEM.

The addition of a carbon fiber spoiler to the Model S stands out in contrast with the smooth lines and uniform color of the car, with a flash of glossy carbon fiber. It takes the rear of the car from smooth to standout with a bold new line that cuts away from the car, often inciting a double take to catch the extra pop of flair.

Carbon Fiber Nose Cone Applique

Up at the front of the Model S, the EV Annex guys created a carbon fiber nose cone applique that cuts around the Tesla emblem with such precision, it looks almost as if the carbon fiber were poured in around it as a liquid (it wasn’t).

While the carbon fiber that the spoiler is made from is rigid, the applique for the nose cone, while also made with real carbon fiber, is comprised of a flexible layer of carbon fiber covered with a protective rubberized coating that serves a very similar function to the clear protective paint coatings many high end cars come with (like opticoat). The front of the car is extremely prone to chips in paint — or in this case, a carbon fiber applique — so I was happy to see that it came with its own protection.

Speaking of protective coatings, I chose to remove my protective paint coating prior to installing to ensure the best bond with the car. After all, this new beauty would both improve the aesthetics as well as protect the car. so it was a win-win. To remove the coating, I worked my way to the edge of the upper nosecone section to where the coating ended and just started pulling it back, like a large vinyl sticker. After a few minutes, it was off.

I gave the nosecone a quick cleaning with window cleaner, then some alcohol, to ensure a tight bond with the new piece, and was ready to apply it. I read the instructions once more (read twice, apply once :)) and was ready to go. I removed the backing on the rear side to expose the adhesive, and from there it was a simple matter of taking my time to fit the piece onto the car. It went surprisingly quickly and fit like a glove.

I stepped back to admire it and was extremely pleased at just how quickly and easily it upgraded the look of the front of the Tesla. The carbon fiber nosecone applique adds a nice pop of class to the front of the car, which is especially nice for Teslas with the old nosecone.

Check out the gallery below for a full array of shots of these beautiful pieces on my “No Gasmobile” and head on over to EV Annex to check out the Carbon Fiber Blade Spoiler and the Carbon Fiber Nosecone Applique for the Model S.

Tesla Model S – Thoughts After 1 Year of Ownership

Originally published on CleanTechnica

In December 2015, I hatched an admittedly convoluted plan to purchase a Certified Pre-Owned (CPO) Tesla Model S some 2,600 miles away in Columbus, Ohio; fly out to pick it up; … then drive back to my home in California with a few fun stops along the way. Thankfully, just about everything worked out flawlessly and I made it home safely.

Picking up my Model S in Columbus, Ohio

Having owned the beast for a year now, I took some time to step back to think about what it’s been like to own a Tesla Model S as compared to our 85 mile range Mercedes B-Class Electric Drive — as well as what ownership is like compared to more conventional gasmobiles.

Summary

Taking a 30,000 foot view of the last year, it has truly been phenomenal. The car drives like a dream. It’s quiet. Thanks to the skateboard design of the battery pack, it has an amazing center of gravity which is a key contributor to great traction, which doubles up with the super intelligent traction control system that all but prevents the wheels from slipping and “burning out.” It’s packed with technology making an IT geek like me smile every time I get in. And it has enough range to make range anxiety a thing of the past.

The Power of the Supercharger

While on my road trip, I vetted the Tesla Supercharger network, which I found to be more than sufficient for long-distance road trips across the arterial highway routes in the US, and with more Superchargers being added seemingly every week. Coming from a year of driving my wife’s electric Mercedes and a few months in a Nissan Leaf of my own, the Tesla Supercharger network truly was a game-changer.

supercharging_colorado

With CHAdeMO and SAE Combo Level 3 chargers (aka DC fast-charging stations), there are usually only one or two chargers per location. On top of that, they aren’t fast enough to add enough range to truly enable anything even remotely resembling a road trip. On the Chevy Bolt, for instance, stops will have to be ~60 minutes to get a 20–100% charge. Yes, that’s not terrible, but it’s also less than half the speed of a Supercharger, which will add ~170 miles of range in just 30 minutes.

On my road trip and many long-distance trips since, the Superchargers provide the perfect balance of a pit stop — time to go to the bathroom (which are typically in high demand after 2+ hours of driving with my family), grab a coffee or a bite to eat, stretch my legs, and get back on the road. Extending that to an hour adds quite a bit of idle time to the agenda. Yes, it’s still possible … but it’s going in the wrong direction.

20160422_120937

Supercharging is a game-changer for today’s EVs and becomes an absolute “have to have” for EVs with 200+ miles. This single fact will become evident as the masses of Bolt owners hit roads around the US over the next few months.

Service

For better or worse, I was able to experience Tesla service firsthand a few times over the last 12 months. I had my door handle extending mechanisms replaced, which took a ranger appointment and an in-house visit to fix completely. Initially, they were only going to replace the one … but when they were at my house fixing it, they confirmed that the others needed to be replaced as well. To Tesla’s credit, the process was painless and they came out and picked up my car, brought a loaner to me, and vice versa to return my car to me.

Everything about how Tesla processes service requests to how the services are scheduled to the unique approaches to repairing vehicles is a vast improvement over conventional dealerships. For the first door handle, Tesla offered to fix it in my garage with the Ranger service. That meant no dropping my car off, no waiting an hour at the dealership, no hassle of loaner cars … I opened the door and they went to work while I went inside and made dinner. It was great.

For the seatbelt recall earlier this year, Tesla staffed service techs at Supercharger locations to perform the quick 5 minute recall check in order to make it even easier for customers. This was a great example of how Tesla can and is leveraging its unique differences to improve the customer experience.

20160712_170951

In another interaction with Tesla service, I received a proactive call from Tesla Service to schedule a replacement of an electrical switch for the battery that wasn’t performing up to Tesla’s high standards. There was no impact to me and I received a loaner for the duration of the check. It took all of 1 day and I actually enjoyed getting to try out a different configuration of the Model S for a day.

This shows how Tesla is thinking of the vehicle as more of a smartphone than a car. Remote monitoring of vehicle health including diagnostics enables a level of preventive maintenance that simply does not exist in other car companies. This is just one more example of how Tesla doesn’t just have the longest range EV on the road but has exceeded current vehicles in just about every way.

Finally, in my most recent service experience, a notification popped up in my car that my 12 volt battery needed to be replaced. This was a known issue but it happened 2 days before Thanksgiving — for which we were planning to drive several hours a day for the entire weekend. I called Tesla and in under 5 minutes on the phone Tesla had confirmed that the battery needed to be replaced (again remotely, with no action required from me), confirmed that the battery didn’t need to be replaced immediately (had 2 weeks of life left), and had an appointment booked for early the following week.

20160103_110611

Overall, my Model S has had more service issues in 1 year of ownership than my Prius did over 6 years, but frankly, because of how much better the car is than any other car out there, AND just how painless Tesla Service is, I don’t mind it one bit. In fact, I enjoy calling them about an issue because they’re just so darn good at doing service.

A point of caution moving forward: it will be challenging to deliver the same high quality of service as they do today when Model 3 … and Model Y come online. I fully expect service staff to grow over the next 2 years and for the number of service locations to increase accordingly.

The Best Jerry, The Best*

My favorite part of owning the car is the rearview mirror. It’s no technical marvel — though, it is photochromatic, meaning it gets darker when bright lights (headlights) are shining in it, but that’s beside the point. I love seeing the people behind me pointing at my car and having little discussions. In addition to being in a Tesla, which draws looks by itself, my license plate is “NOGAAAS,” which helps close the gap for folks who aren’t as familiar with Tesla or electric cars.

I imagine what they’re saying and can honestly tell when they are talking about the car. I love that the car gets people talking about it. They may just know that Tesla is a nice car or a fast car or a high-tech car, which gets people excited about it … but it’s also an electric car, and to have people excited about electric cars and to get them talking about them is a huge win.

The car starts the discussion and I’ve swooped in many times to fill in any gaps in knowledge about it — dozens of times over the months I’ve owned it. For people I know, I’ve had several dozen people drive it. Again — it’s a sexy car and that draws people in and gets things going. Perhaps unsurprisingly, nobody was asking to drive my LEAF when I owned it … or my wife’s electric Mercedes. The Tesla is a different beast.

*This subheading refers to a somewhat obscure scene / character from the popular sitcom Jerry Seinfeld. 🙂

Put a Bow on It

In summary, this is the best car I’ve ever owned. When combined with the Supercharging network, it definitively puts range anxiety to rest once and for all. It packs more tech than any car I’ve seen in a way that’s more intuitive than I would have thought possible. It drives better (and quieter!) than any other car out there, and is faster to boot.

The Tesla app on my smartphone gives me all sorts of fun control and visibility of what it’s doing that has been helpful to me more than a few times. It can even unlock and turn on the car, allowing it to drive without a key in it. My wife — who’s not the most tech-friendly person and not a huge EV fan — feels comfortable driving in it with minimal instruction … which is great for my stress level and our marriage. 🙂

The only downside is the price … and that’s going to improve by leaps and bounds in another 12 months.

The Tesla Supercharging Crisis On The Horizon

Originally published on CleanTechnica

With several affordable vehicles on the horizon that will be capable of 200 miles or more of all-electric range, the last major problem for EVs and EV manufacturers to truly solve is super fast public charging, or what we have dubbed Level 4 charging.

Tesla is currently the only automaker to offer reasonable long-distance charging with its Superchargers running at ~135 kW, but that infrastructure is about to be pounded into the ground by hundreds of thousands of Tesla Model 3 owners unless something changes.

In the Model 3 unveiling last week, Elon Musk shared that Supercharging would be included with the Model 3 but stopped short of claiming that it would include free Supercharging, as has been the case with the Model S and X. This is a divergence from previous statements that Supercharging would be free for the Model 3.

Tragedy of the Commons

Looking at Supercharging, one of the key challenges is that it’s free. When humans can get something for free, even when it’s just a few bucks worth of power, we act irrationally and selfishly, which is a behavior captured in a theory call the “tragedy of the commons.” Per Wikipedia, the tragedy of the commons is:

“an economic theory of a situation within a shared-resource system where individual users acting independently and rationally according to their own self-interest behave contrary to the common good of all users by depleting that resource.”

Stories of wealthy Tesla drivers using Superchargers every day as their main charging solutions are on the forums and are evidence of this behavior. Spending 30 minutes every day to sit around to save $3 in electricity at home is not a logical behavior for someone driving a $100,000 car, and results in charging stations being unavailable for long-distance drivers.

Tesla has already reached out to frequent … excessive … abusive … and even some infrequent Supercharging users, asking them to take it easy … and this is just with the Model S putting load on the Supercharging network. Imagine when we have 2 more years of full production volume of the S and the X weighing down on  it… Tesla Superchargers could be in for a world of hurt in no time, as defined by long lines and general unreliability of the Supercharging network.

Why Supercharging

Fixing Supercharging doesn’t mean that all of a sudden everyone has to pay for Supercharging. Stepping back from the problem to look at why Supercharging exists in the first place helps us to understand what levers can be pulled to improve the system.

Tesla developed and deployed Supercharging to fill a functionality gap for EVs and to enable long-distance travel. That’s the base use case and in these early days of Level 4 infrastructure deployment, the key reason for Level 4 chargers. This is not saying that Superchargers are not great for a quick topup or for filling up after a long day of driving around town … but that’s not what Tesla built them for.

As Supercharging networks continue to grow, there will be a natural evolution of the system to support additional use cases, but in the meantime, there is an opportunity to leverage system controls to optimize system availability. Long-distance travel and fast charging become much more relevant considerations as EVs with more than 200 miles range become the norm — as long-distance travel with sub-100 mile range EVs is painful in most scenarios anyway.

The Radius Model

Finding the sweet spot in keeping the system functional while also assuring availability is a delicate balance but is not unsolvable. Implementing a system wherein charging closer to home is not free provides an incentive for EV owners to charge at home and lightens the load on the distributed public charging network that otherwise becomes clogged by the tragedy of the commons effect we typically see with free charging.

Great availability, low utilization | Image Credit: Kyle Field

For local charging within 50 miles of home, it is critical to bill for EV charging, as this is where 90%+ of all driving takes place. When local charging is not regulated, EV drivers gravitate towards utilizing public charging stations instead of home charging, which consumes charging spaces that could otherwise be useful for long-distance travelers. A healthy price point for local charging would be to use peak electricity rates.

For mid-range charging at ranges of 50–100 miles from home, an EV driver can still round-trip a destination on a single charge, so public charging at these distances is not absolutely required. Charging pass-through rates for power at mid-range charging stations strikes a balance that allows EV drivers to charge remotely without a penalty but clearly removes the incentive to “convenience charge.”

For long-range charging over 100 miles from the home, Level 4 charging can remain free as this is the intended use-case.

Implementing a radius model to govern charging ensures that chargers are available for the base use case while also giving EV drivers the freedom to utilize public super fast charging stations if needed, with minimal penalty. For EV drivers without home chargers, workplace chargers provide the best balance between cost, availability, and charging time.

As the Level 4 charging network catches up with EV sales growth, models can be adjusted to strike the right balance between cost, availability, and charging time. Currently, the balance is tenuous at best, but with Tesla being the only EV manufacturer to truly invest in a Level 4 charging network and ensure integration with its fleet of EVs, the balance is sure to deteriorate as Model 3 comes online.

Tesla Model 3 on the test track | Image Credit: Kyle Field

At the Model 3 unveiling last week, Tesla shared plans to double the Supercharging network by the end of 2017, and a parallel effort to improve the destination charging program with a planned four-fold increase in the same timing.

Building and managing Level 4 public charging is a key step to ensuring robust EV charging that meets the needs of EV drivers, but with Model 3 on the horizon, it is at a critical junction as EV adoption moves from the Early Adopters to the Early Majority and the volume of EVs on the road ramps up significantly. Left unmanaged, the volume of vehicles would quickly overwhelm the current and planned super fast charging network and render it effectively unusable.

My Epic Tesla Road Trip

Originally published on CleanTechnica

teslogo

Upon rolling out of the Tesla Dealership… er… Service Center in Columbus, Ohio, a few things hit me right off the bat: The new-car feeling, realizing that this was my car. The realization that now I really was pretty much on the other side of the country and actually had to drive back across the ~3,700 kilometers at around 33 hours of driving. The fact that I only had one room booked between Ohio and Vegas … and what the heck, I just bought a Tesla!?!

I wanted to take off like a bat of hell and drive 120 miles an hour down the road, tearing up the asphalt… but I’ve been there and done that and tickets (and accidents!) are expensive no matter what state you’re in. So I calmed myself down, took a sip of the coffee CJ had so generously hooked me up with, set the cruise control for 65, and pointed the wheels to the west.

The next day, after a few hours of rest, several stops at Superchargers, hundreds of miles, and too many cups of coffee, I had a good feel for the car and how it worked on long road trips. While the car generally met my expectations, a few things stuck out to me about the car that I hadn’t expected.

Automagic Unlocking

Locking the car, for one. The Model S automagically locks (it’s an optional setting) when the driver walks away with the key fob. At first, I would nervously look out at the car from the gas station, coffee shop, or lunch stop to confirm that the handles were in, lights were off, and all that. After several stops, I realized that it just works. Put it in park, get out, walk away, and you’re good. It’s awesome. No parking brake, no locking or unlocking the car… easy.

Power at Your Fingertips

The power of the car is also amazing. With a single-motor, non-performance version of the Model S, I was not expecting amazing performance, but it blows me away. I used to have a ’97 Pontiac Trans Am, which I had done some work on, so I’m familiar with performance cars, but the smooth, torquey power of the Model S is a different beast altogether, and a lot more fun in my opinion.

Going 30 but want to go 65? Done. Going 65 and want to pass the smoggy diesel pickup in front of you? No problem. It’s something I’m still working on dampening, as it just begs to go faster than most laws allow. My favorite is pounding the pedal while cruising at around 20–30 miles per hour. It jumps like nothing else… okay, except may be a P90D with Ludicrous Mode :D.

Supercharging in Colorado

Supercharging

I will go into more detail about Supercharging in a separate article, but suffice it to say that it blows the competition away. Triple the speed of the next fastest charger, predictable, built into the navigation, and easy to use. It’s great. I loved being able to punch in whatever destination I wanted, however far away, with the confidence that the car would navigate to the nearest charger automatically.

Most of the Superchargers were located at hotels, gas stations (of all places!), shopping plazas, and otherwise near facilities that could occupy 30 minutes of a day, which was nice. A few stops required a bit more creativity to answer the calls of nature or get a bite of food. I found the ability of the car to keep the heating on while charging to be a great feature that I took advantage of extensively on my journey.

Indecisive Navigation

One glitch that I noticed in the navigation is that, after topping up at a Supercharger then heading down the highway, the navigation would occasionally try to route me back to the charger I had just left (after charging for the amount of time it told me to charge for).

This even happened a few times after I was 20 minutes down the road like it suddenly realized I needed more capacity to make the next charger. It did not make sense to me, as I typically had 50–80 miles of “spare” range above and beyond what was required to get to the next charger. It was not a deal breaker and I was able to manually navigate through it by turning off charging stop recommendations, but it seems like a bug in the logic that could be corrected.

Navigation Range Estimation

Along similar lines, the navigation is conservative, but with caveats. First — it is conservative as it tries to ensure that you have WAY more charge than needed to get to the next destination. If I’m going 65 miles to the next charger, it wants me to have at least 110 miles of range to move on.supercharging

The caveat to the estimated range is that external factors like elevation gains, climate controls (heating/cooling), driving speeds, and outside weather can (and did!) have large impacts on range. It was not clear if the navigation was actively taking those factors into account — or at least for the static, predictable factors — but it seems like it could more accurately describe why it wants more charge at certain times.

On my trip, I drove over the Rocky Mountains (very steep, cold mountains in the Western United States), drove in sub-zero temperatures, and as a result, used the cabin heating frequently. I was aware of the impacts these would have, but an unfamiliar driver, not realizing the interrelationships between these factors could easily end up stranded in their Tesla. These factors are also present in gasmobiles, but with gas stations on every corner and most freeway exits, it is less of an issue. Growing pains…

The video below details some of my jumbled learnings from the road. I was happy to find that the speedometer display was the right angle to capture this specific angle with my phone, making it easy to record videos and video chat with my kids while out on the road. Technology is amazing.
