Our Volkswagen ⚡ ID.3 Factory Tour Photo Album
November 6th, 2019 by Steve Hanley

At the Volkswagen ID.3 Start of Production ceremony this week, journalists from around the world were treated to a tour of portions of the assembly line to see for themselves how the highly automated factory functions. The heart of the operation is what the company calls its MEB platform, which is a toolkit for building a variety of electric cars using a standard architecture. Here’s why that is important.


Going back a few years, Tesla wanted to leverage its success with the Model S by making an SUV variant. Originally the idea was to use the Model S chassis, but as things went further and further along, the two cars became quite dissimilar. In the final version, about 70% of the parts for the Model X were unique to that vehicle. As good as the Model X is, Tesla lost an opportunity to maximize production efficiency, which is a key component of being profitable.

That is not a knock on Tesla. It was just beginning life and learning by making mistakes and fixing them. Today, the Model Y SUV is in the pipeline and it will share many more parts with the Model 3 that it is based on. Volkswagen has been building cars for many decades and it has learned a thing or two about making the process as efficient as possible.

If the charging port for every Volkswagen electric car is in the same place, that means no changes have to be made on the factory floor to switch from one model to another. That saves times by eliminating the retraining of workers and reprogramming of robots,. The result is  lower production costs and higher profits.

Some of the other factors the cars will have in common  include standardizing the attachment points for the suspension, motor(s), battery pack, battery management system, and seats. Even standardizing where the air conditioning compressor and ducts are for the climate control system is important when building millions of cars.

Below are photos taken during the tour. All were taken by the author and may be shared or republished with proper attribution. Shall we begin? In the first photo,  you see the jig that all the components are mounted to before the skateboard — battery, suspension, drivetrain, and wiring — are married to the body of the car. The tall black uprights with pointy ends fit into spaces in the body to align everything perfectly so it all  goes together accurately.


The first component that gets loaded onto the jig is the battery.


Then the drivetrain and rear suspension are added, followed by the front suspension together with the steering and air conditioning systems.




Meanwhile, the body is arriving from the stamping facility and paint shop.



Today, workers add the headliner through the front windshield opening. This used to take 5 workers when this assembly line built Golf vehicles. Today that is down to 3 workers and the process will be fully automated in the near future.



Next, the body and the skateboard are joined in what the company calls a wedding. First the skateboard is moved into place beneath the body, then raised into position. 24 automatic ratchets insert and tighten the bolts that hold the two pieces together. In the first edition cars, the heads up display is included in the skateboard at this point.




Next the chassis proceeds down the line where seats and doors are installed. Components like front windshields and front suspension components are stockpiled where needed along the production line.



The whole process moves along quite slowly at the present time while everyone learns how the new factory works. The noise level inside the factory is no more than one might expect in a public park. Break rooms and dining facilities are scattered throughout the factory and everyone — workers and management — share these facilities so they can learn from each other as the process of ramping up production continues. Thomas Ulbrich, who is in charge of coordinating all aspects of Volkswagen’s transition to electric cars, has been known to sleep at the factory and jump in to twist wrenches when necessary to get a better understanding of what problems arise on the line and how to solve them.

By this time next year, this production facility that used to build conventional cars will be turning out 800 electric vehicles a day. There will be four lines just like the one shown in the photos in operation. In another part of the factory complex, a second assembly area for conventional cars will be shut down and reconfigured to build EVs, making Zwichau the largest electric car manufacturing facility in Europe

Scorpion is a single-seat, altitude limited quadcopter hoverbike which started as a “crowdfunding” project.

Here's an interesting video showing lots of flying platforms (some of them are not electric 👎). The last one with some dude in a hammock being hovered around is hilarious!

All the "it's ugly" comments actually surprised me.

Why Is The Tesla Cybertruck A Giant Triangle?   

November 24th, 2019 by Kurt Lowder

Why is the Tesla Cybertruck a giant triangle? The list of potential answers below is randomly ordered, not in order of importance. Some of the reasons are more speculative than others and may be incorrect or coincidental/unintended:

1.) The Tesla Cybertruck is shaped like a triangle so it can win a race backward. Yes, that is mostly a joke, but it certainly is a conceivable feat. Imagine a fan-made video or commercial where the Cybertruck beats another vehicle backwards! Not sure if the powertrain design will allow for this, but the aerodynamics should.

2.) While Cybertruck’s design is a shocking departure from a conventional pickup, in general, symmetry is naturally viewed as more beautiful. There may be many benefits to having a more symmetrical design. I expect the symmetry of the Cybertruck to grow on people. Of course, the Cybertruck is not perfectly symmetrical, but it is more symmetrical than a conventional pickup truck.

3.) The triangular design improves the center of mass, creating a more balanced vehicle. It’s going to be very rare for this vehicle to flip.

4.) Safety. The triangular design allows the passengers to be centered closer to the midpoint of the car. Doing so further protects passengers from both forward and rear collisions.

5.) The more symmetrical design may increase the ease of manufacturing.

6.) My next speculation may be a bit absurd, but I think its rationale is based on first principles and economics.  I think it is likely the Cybertruck platform could be altered to build shuttles for use in The Boring Company tunnels. Or, at least, lessons learned from the Cybertruck could apply towards building the future shuttles. The two vehicles may share many parts. To date, all The Boring Company projects are loops comprised of two tunnels; one for each direction. However, a project does not have to have two tunnels; it can have only one.

Imagine a single tunnel where a platoon of Cybertrucks (or shuttles) just goes back and forth from point A to point B like the video game pong. In this configuration, there is no need to ever turn the shuttles around. This is how many metro trains operate. This type of tunnel project would be quite short, so that departure times still occur frequently. I could imagine such a tunnel connecting an airport to a train station, or a stadium to an event center. Pardon the poor Microsoft Paint diagram, which illustrates this single tunnel concept:

7.) The Cybertruck is shaped like a triangle to be different and really garner attention. The Cybertruck is no doubt polarizing. So far, most people love it or hate it! But that constant debate brings attention and certainly just seeing the Cybertruck makes it immediately recognizable.


Allow me to bring up an illustrative but imperfect analogy: Kim Kardashian. Kim is certainly a polarizing person, but so much of her business is based upon the constant polarizing attention she gets. Whether people love her or love judging and condemning her, they are clicking on articles about her. The constant clicks give her an audience to generate income from. This example is repeated over and over again in commerce and media. Howard Stern has made a fortune by being polarizing. He stood out among DJs because he was so shocking. The Cybertruck has shock value in spades.

8.) It is all about the cold rolled steel! The exterior steel alloy of the Cybertruck is extremely hard and durable. As such, it may be easier to manufacture if the design is comprised of flat surfaces and abrupt angles. The harder material could require much more effort (expense) if fabricated to create a more curved design.

So, it’s really the material that may be dictating the shape. Tesla’s other vehicles have had smoother, more aerodynamic curves, which are allowed via a much softer metal alloy. The triangular Cybertruck is aerodynamic enough. Tesla has created a balance between being aerodynamic enough but also using a material that may economically demand a more linear design with abrupt angles.

9.) Tesla is finally considering putting solar panels on a vehicle. This triangular design creates a flat, sloped surface to which solar cells can be attached. Initially, it appears the solar will just be on the back of the Cybertruck. Could solar be embedded in the glass? Maybe. Initially, the goal is to get 15 miles of range from solar per day. The aspirational goal is 30 miles.

For the most part, solar on a vehicle is considered a gimmick and uneconomical. The argument is: “Just put solar on your roof or carport to charge your vehicle; it will be cheaper.” However, having a vehicle generate its own power is very compelling to a number of individuals. I love the idea of a road trip where I go only as far as my solar panels can take me.

Every day, I could go 10–20 miles to a new camp spot and still have power. Or every three days I could for 30-60 miles to a new camp spot. Or, I could drive 200 miles into the remote wilderness, camp a week, and have enough power to drive back without needing a Supercharge. To some, it’s a gimmick. To others like me, it is a challenge. It will feel like traveling the Oregon trail. I can only go as far as my oxen (solar panels) will take me.

Over time, solar cell efficiency will improve and allow more daily range produced from solar.

10.) This comment comes courtesy of commentator JerryRCD. It has a triangular design because it can. The Cybertuck’s design is formed around a flat EV skateboard architecture which contains small but incredibly powerful electric motor(s). The shape of a conventional truck is designed around a massive internal combustion engine and the pickup bed. No need to stick with the old design that was created around an obsolete internal combustion engine. The conventional pickup truck design is not optimized for the EV skateboard architecture.

11.) It looks like a stealth bomber!

12, 13, …) Comment section. Let us know what you think. Also, feel free to abbreviate the reasons above and rearrange them in order of importance.

I actually think #8, if correct, might be the #1 reason. I am not certain about #8, though; it was an idea proposed in this great HyperChange video:

1) It's the most aerodynamic shape they can make with their material choice and manufacturing process. Better aero means less batteries means lower cost to reach a specific range.

Agelbert > David

As soon as I saw the Tesla EV ⚡ Pickup, I thought of the Delorean (see: Back to the Future movies), but aerodynamically cleaned up 💫👍.

Delorean

Tesla EV ⚡ Pickup

All the "it's ugly" comments actually surprised me.

After pondering that for a while, I could only conclude that vehicle manufacturer advertising legerdemain over the last century has thoroughly distorted car buyer concepts of what constitutes a "pleasing appearance". 😟

All the "trim" stuff that auto makers have been hanging on their buggies since horses started to drag them around have been nothing but social climbing status symbols.

When Madison Avenue got into the ACT (See: there's a sucker born every minute), hood "ornaments" of horses, rockets, Native Americans (and so on), along with chrome strips here and there created envy based brands (for extra 😈 manufacturer profits), which actually just added weight and drag to the vehicles. 👎

Creating style envy based on hyping class privilege symbols is socially devisive AND destructive. 👎

Yes, Tesla has a BRAND. Yes, that brand lamentally does produce envy. BUT, it is based on non-polluting clean energy and efficiency, not hype. Spurring people to get a non-polluting clean energy powered vehicle (i.e. an ⚡ EV) is a socially beneficial motivation. 👍


Your vehicle is NOT YOU! Stop believing the hype! Your vehicle is what you need to get you from one place to the other, not your 'royal carriage' used to make your neighbors jealous.

The Tesla EV truck is all about getting the hauling stuff job (on road or off) done with LESS energy. THAT is all people of good will should care about.

Vehicles with mean looking grills in the front are a drag inducing feature of all internal combustion vehicles that have NO PLACE in EV design. Musk gets that. So should you.

To give you an idea how important it is to have a vehicle, whether it be a flying machine or a Telsa EV, as free from parasite drag (a specific category of aerodynamic drag that convoluted bumper grills, and anything else sticking out, cause) as possible, I'll give you a vivid example of how a small part can cause a huge loss of efficiency.

A long time ago I flew Piper Navajo Aircraft for an air taxi.

Navajo (Pa-31) pictured below:

Sometimes I had to keep the speed high on approach to please the tower controller. That would put me in a bit of a fix because I had to slow down quickly just before landing so I wouldn't use a lot of runway in the roll out. At about 160 mph (throttles all the way back and descending) I couldn't lower the gear or flaps (which massively increases drag) because of the high approach speed (I needed to to get below about 150 mph for gear and 130 mph for first flap setting). I would adjust the props "forward" (flat pitch increased the drag). That would slow me but not quick enough.

Since the descent kept my speed up until I was over the runway threshold, I would be left with the embarrassing position of floating over the runway until I could lower the gear and apply full flaps. All that would result in a really long landing roll.

Well, I would avoid all that by activating a tiny part under the cowling of the twin Lycoming 350 hp engines. This part is about 12 inches long and 5 inches wide. It is called a cowl flap. The purpose is to cool the engine during a high power setting slow approach. BUT, I discovered that opening the cowl flaps at around 160 mph (unlike the gear and flaps there is no limit to the speed you could be at to open them) would instantly drop you 10 mph! I could then lower the gear, which would drop me into the flap arc so I could apply full plaps and land quickly.

Picture of Navajo with right engine cowl flap open:

The cowl flaps only extended about 6 inches into the slipstream. This tiny robust part, in comparison to the overall aircraft size, caused so much parasite drag that the aircraft slowed quickly.

Musk knows what he is doing. By the way, the ability of the Tesla EV Pickup to seal the back is a HUGE drag reducing feature 👍, not just a way to keep the rain or a thief from getting to your load.


The Tesla EV Pickup is, even more than the other already well designed Tesla vehicles, common sense in vehicle design borrowed from aircraft manufacture and design, NOT Madison Avenue hype. That alone will make it an even greater success than its efficiency guarantees. It's time to let go of the Madison Avenue promoted class privilege hyping, envy producing, socially destructive, vehicle design symbols bling.

"Divers weights, and divers measures, both of them are alike abomination to the Lord. Even a child is known by his doings, whether his work be pure, and whether it be right." -- Proverbs 20:10-11

EV Boom ✨ — Roger & Zach Chat Lithium, EV Forecasts, Ford Mustang Mach-E

December 9th, 2019 by Winter Wilson

In our first ever episode of a new “EV Boom” podcast interview series, Zach Shahan sits down with Roger Atkins, founder of Electric Vehicles Outlook Ltd and self-described “jack of all trades, master of none,” to discuss Roger’s insights into lithium-ion batteries and the electric vehicle industry. You can listen to the full conversation in the embedded player below. Below that embedded SoundCloud player is a brief summary of the topics covered, but tune into the podcast to follow the full discussion.

🔊 Podcast

s Roger explained early in the podcast, “necessity is the mother of invention.” Have an issue that needs to be resolved? Creative people will come up with a solution. That is why electric vehicles have become a primary focus in the wake of increasing global challenges with city congestion and pollution, Roger said.

But while electric vehicles have proven to be promising solutions to these clear and immediate challenges, Roger worries about the lithium mining supply chain. He believes that due to a limited supply of automotive-grade lithium, the most electric vehicle share possible by 2025 would be only 7% of the global automotive market. This is what Roger picked up recently at a Benchmark Materials conference from a top lithium expert (“Lithium Joe,” who is reportedly the world’s leading authority on lithium supply), and it goes against Roger’s previous viewpoint on the topic. Even though there is currently an overflow in lithium, Roger explains that the future will prove difficult. It is not about whether or not we have lithium, he said — it is about whether that lithium is high enough quality for safe batteries.


Keeping in mind the challenge of lithium-ion batteries, Zach and Roger move on to discuss current industry players who are making big steps into the electric vehicle sector. They talk briefly about Ford’s investment in Rivian and Ford’s efforts to jump into the electric vehicle world through the Ford Electric Mach-E. But the foray into electric vehicles is no easy feat for established automotive companies. There is a huge challenge to profitability, Roger explains, as sunk costs and investment for research and development to transition into electric vehicles can combine to be crippling to a company. He believes, however, that working together with new electric vehicle companies, as Ford has done with Rivian, can give more established industry players a leg up.

Zach and Roger discuss how current politics and social media influence have driven the demand for climate action and, consequently, electric vehicle production.

Roger Atkins

But Roger believes that looking beyond battery supply to other ways to maximize battery capacity is important. One critical piece of this dialogue, he said, is shifting from a linear economy to a circular one. He explains that the narrative should focus on maximizing efficiency and utilization. Roger proposes an increased use of carsharing, multimodal transportation development, and improvement of public transportation. Zach and Roger also briefly touch on automatic wireless charging in place of cable charging.

Roger expresses his desire to see strong leaders leverage the momentum behind the transition into electric vehicles to push exponential development of more efficient and sustainable transportation. His advice? “You better get on with it, because before too long you’ll be left with the people you won’t really want to dance with!”

To hear more on these topics, as well as hear Roger’s advice for how to be an innovative leader, listen to the show! 🌞

SNIPPET:

In a previous article, I did look at BEV model popularity relative to each other. Now, the focus is on the competition between the ⚡BEV market and the 🦕FFV market. New BEVs and “Golden Oldies” (older BEV models) with more range changed this competition drastically. The competition with 🦕gas guzzlers no longer started at €85,000. Now, there were serious alternatives starting at €35,000, some of which were hatchbacks, others SUVs or CUVs.

⚡ Appscooter Images courtesy: Etergo

The AppScooter will be available with 3 motor configurations: 2 kW, 4 kW, and 7 kW motors. The 2 kW motor allows the AppScooter to reach speeds of up to 50 km/h / 31 mph, the 4 kW motor has a maximum speed of 70 km/h / 43.5 mph, and the 7 kW motor variant can reach 95 km/h / 59 mph. That’s basically already highway speeds.

⚡ Appscooter Images courtesy: Etergo

The most basic variant costs 3,399 euros ($3,800) and only includes one battery with extra battery modules sold separately. The medium motor package comes with two batteries and is the most popular option at 4,297 euros ($4,805) . The top-tier configuration comes with the peppy 7 kW motor and 3 batteries but will set buyers back 5,246 euros ($5,866). Now, I originally was wondering whether it might have just been one type of motor that was limited by software, but turns out there really are 3 different motors.

Agelbert NOTE: All these electric three wheelers like Electric Ape are basically electric tuk-tuks. The Electric ape will be made for India but in the USA you can buy a similar looking vehicle called an eTuk (see pictures below). They are based in Colorado and market them for tourist mobility and small business roadside vendors:
