Tesla 4680 Battery Pack

The bottleneck for Tesla is not so much producing cars, but acquiring sufficient battery capacity for them.

Analysts expect slip in US EV-maker’s second-quarter results; Critical launch of self-produced battery has suffered series of setbacks. Tesla Inc has weathered the pandemic and supply chain crisis better than many of its rivals, achieving record deliveries last quarter – but Chief Executive Elon Musk now faces pressure to deliver on breakthrough batteries and new factories and models, which are late… Musk last month pushed back the debut of the 4680s by cancelling the longest-range Model S Plaid+, which he had said would use the cells, sparking concern. He has said 4680s would go into volume production next year and would be used in the Model Y from the Texas factory under construction. Now, Tesla aims to produce vehicles with 4680 batteries starting with small volumes this year in as-yet-unfinalised models, sources told Reuters.

A little skepticism here:

[wired.com] – Where Was the Battery at Tesla’s Battery Day?

Musk had promised to show the world something “very insane” that would result in a “step change in accelerating sustainable energy.” This turned out to be a fat lithium-ion battery called a 4680—a reference to its diameter, 46 millimeters, and its length, 80 millimeters—that is being produced in-house at Tesla. To be sure, Tesla’s new battery appears to offer large performance gains in a few key areas, but it was unclear whether Tesla has actually achieved these upgrades or whether this is the projected performance for the finalized battery.

Solid State Battery Last 20 Years

A solid-state battery is a battery technology that uses solid electrodes and a solid electrolyte, instead of the liquid or polymer gel electrolytes found in lithium-ion or lithium polymer batteries.

While solid electrolytes were first discovered in the 19th century, several drawbacks, such as low energy densities, have prevented widespread application. Developments in the late 20th and early 21st century have caused renewed interest in solid-state battery technologies, especially in the context of electric vehicles, starting in the 2010s.

Materials proposed for use as solid electrolytes in solid-state batteries include ceramics (e.g., oxides, sulfides, phosphates), and solid polymers. Solid-state batteries have found use in pacemakers, RFID and wearable devices. They are potentially safer, with higher energy densities, but at a much higher cost. Challenges to widespread adoption include energy and power density, durability, material costs, sensitivity and stability.

Solid state batteries allow the body of the car to be used as a battery.

BYD Blade Battery Breakthrough

BYD of China has introduced a lithium-iron-phosphate blade-shaped battery, that should replace conventional cylinder-shaped batteries. The BYD e-platform 3.0 promises advantages on energy density (and hence range, now up to 900 km), charge time (135 km range in 5 minutes), safety, cost, longevity (3000 cycles or 1.2 million km) and environment (elimination of cobalt).

With breathtaking down-to-earth specs like these, it can be foreseen that the public will flock en masse to e-vehicles, replacing the green avant-garde that had more high-minded environmental motives to support the mobility transition.

Well, what-ever it takes to get the job done.

An avalanche of e-vehicle adoption will trigger an avalanche of demand for green power generation. The average daily distance driven in NW-Europe is about 34 km (Netherlands). A 900 km range means an average visit interval to the charging station of 26 days. This results in beneficial storage consequences; it isn’t exactly seasonal storage, but it is much longer than pumped hydro capacity of basins high in the mountains of Norway.

Germany Finally Falling for its Own Products

Until recently, Germany preferred to manufacture and sell e-vehicles, rather than drive them. Thanks to a federal subsidy, this is now changing. The fact that e-vehicles accelerate much faster, could be a beneficial factor as well, as Germans are generally intrigued, if not obsessed, with speed, horse-power and acceleration of their liebstes Kind (“most beloved child”).

More in general, e-mobibility is taking Europe by storm, illustrating that world-wide, the renewable energy transition is progressed most in the “Old Continent”, as Americans prefer to call us, suggesting that Europe is lagging behind America.

The data suggests otherwise.

Recently, Donald Rumsfeld died.
Of old age.
RIP Donald.

Cambridge-UK Autonomous Shuttle Trial

Youtube text:

Aurrigo, which has been hugely instrumental in the development of ‘first and last mile’ transport solutions, will become the first firm in the country to undertake testing of a custom-made autonomous vehicle capable of carrying passengers on a main road surrounded by other traffic, including cars, lorries, vans, bikes and pedestrians.

Able to seat 10 people outside of social distancing restrictions, the three shuttles will take passengers from the Madingley Road Park and Ride site to and around the University of Cambridge’s West Campus.

The trial is part of an Innovate UK and Centre for Connected and Autonomous Vehicles (CCAV)-backed project, led by Aurrigo with Greater Cambridge Partnership (GCP) and Smart Cambridge all working together to explore how autonomous technology could be used on the public transport network.

Tesla Model S Drives 500,000 km

E-vehicles are simpler than gasoline cars and hence need less maintenance. And the cost per km is also lower, certainly in the US, where a kWh cost half or less of hat in Europe. Here a cost breakdown of somebody who has a Tesla with no less than 500,000 km on the counter and still is in perfect shape.

Six years ago car blogger Steve Sasman bought a Tesla Model S with 56,300 km on the counter for 67,000 Euro. He became an Uber-driver with his Tesla and already after 2 years he had 161,000 km. In these 2 years he had:

– 2,000 euro maintenance cost (500 euro standard maintenance, 1,400 for new tires)
– 1,300 euro for repairs (340,- for new battery and 850,- for a new door handle)
– 850 euro or less for electricity

At some point Steve sold his Tesla to Brian, who eventually broke through the 500,000 km limit, when the car was 8 years old.

Steve handing over the car to Brian

All-in-all the total maintenance cost minus tires paid by both Steve and Brian was 9,000 Euro. The car is still in excellent condition.

“By 2030 You Won’t Own a Car”

Hoorn, The Netherlands on a sunny day. Without these ugly parked cars, the 17th century idyll would be restored.

UK consultancy firm Rethinkx has no doubts: the car society as we know it, will be history much sooner than you think. Key word: self-driving car. Once governments begin to allow these essentially driver-less taxis on its roads, the death warrant for the global car industry will be sealed. Why? Because this development would eliminate the need for expensive car ownership completely.

A privately owned car in Western Europe is not used for perhaps 95% of the time (Netherlands: 12,000 km/year, average speed 60 kmh or 200 hours = 5% of a year). Instead the car could be driving during those idle hours, making money in the process and help earning itself back much, much quicker. That’s how every bus, train or aviation company thinks. So why not you, dear mr Joe Sixpack? Because the opportunity to do so is around the corner.

Within a decade or two, technology, infrastructure and government regulation will exist that will enable you to travel the same distances, without actually owning the vehicle. Instead you will order a vehicle with your smart phone and after some time, a taxi will stop in front of your house, but without the taxi driver. And dependent on how much money you are willing/able to pay, you will drive away in a vehicle that is something between a small bus you have to share with others, like in the video below, or a luxury car you will have all for yourself.

Driverless bus in Sion, Switzerland

Take-away points from the study as summarized by Reneweconomy:

  • The future is to transport-as-a-service (TAAS).
  • This implies a death spiral for the car & oil industry in terms of demand for their vehicles and fuel resp.
  • By 2030 most people won’t own a car any-more.
  • By 2030 95% of the miles driven will be done in on-demand, autonomous, electric vehicles (US).
  • The car you are buying now could well be your last (privately owned one).
  • This development will begin in the big cities and spread from there.
  • By 2030 40% of the cars will still be privately owned, but drive merely 5% of the miles (upper income segment).
  • By 2030 1 trillion $ will be saved annually on transport cost (US).
  • Travelling in a driverless vehicle will be 10 times cheaper per mile than in a new or 4 times cheaper than in a used privately owned car.
  • Electric vehicles last much longer and require far less maintenance than petrol cars (20 vs 2000 moving parts in power train).
  • Added benefits: unclogging city roads, eliminating pollution (Asia!), less accidents and freeing up parking space (cities!).
  • Anything can be made driverless: from 2-seaters to buses.
  • Why TAAS will prevail: cost savings, speed, increased safety and extra free time will be key factors.

Death-spiral of the car industry in a single picture. Sudden death in a matter of four years (according to Rethinkx ).

Phasing Out Oil According To Shell

shell-passenger-transport-future
According to a recent Shell energy scenario study [pdf] solar will be the dominant source of energy in 2070. Another expectation is that passenger vehicles will be nearly oil-free by that time as well and could be replaced by a hydrogen infrastructure and electricity.
