Solid State Battery Technology, a Tesla Gigafactory Killer?

Published

on

With 2014 coming to an end, automotive battery news has been trickling out and solid state battery technology appears, again.

In early December, Volkswagen acquired a small equity stake in Stanford-based QuantumScape and Daimler recently announced that its lithium production output will be larger in 2015 due to a new battery plant in Kamenz, Germany, said to be ready by mid-2015.

The VW news keeps the the solid state battery thread for 2014 going as scientists point to its reported improved energy density over lithium-ion technology. A solid state battery does not use a liquid electrolyte like a lithium battery does and, in theory, a solid electrolyte can hold more energy. Yes, please.

Getting rid of an electrolyte—no liquid—can also improve battery safety and reduce costs due to less cooling electronics and micro-controllers needed for pack management, thus reducing weight too, according to Harvard Business Review.

What about downsides to this technology? A solid-state battery has electrical contacts or, electrodes, that are applied to a solid electrolyte—similar to a thin-film solar panel process—and if there’s a lack of uniformity in this process, it can cause short circuits. However, this type of manufacturing application has been done in the thin-film solar area and these obstacles should be easy to overcome.

Earlier this year, Scientific American did a profile on Ann Arbor, Michigan-based Sakti3 and their push with solid-state battery technology and move closer to the “god” battery.

Ann Marie Sastry, co-founder and CEO of the company, said, “that the company’s prototype solid-state lithium battery cells have reached a record energy density of 1,143 Watt-hours per liter—more than double the energy density of today’s best lithium-ion batteries.”

However, as Elon Musk said in the most recent Tesla earnings call,

“Talk is super cheap, the battery industry has to have more BS in it than any industry I’ve ever encountered. It’s insane.”

So is this technology an immediate challenger to Tesla Motors’ Gigafactory strategy? Will this battery technology get ahead of Tesla, due its battery equipment investment at the Gigafactory being close to complete and, thus, no turning back?

No and the reason is battery development takes a lot of time and these recent statements by Sakti3 in the Scientific American article bear this out.

Sakti3 says it’s close to the end of lab work—custom prototype manufacturing line—but then the next step is  on to small scale production and this could take a another year or two of testing before you hit mass production.

That rules out GM going with this type of battery for their mass-produced battery electric vehicle for 2016 or 2017. Plus, Sakti3 mentioned its first aim is small-scale electronics and smartphones.

More importantly, JB Straubel and Tesla Motors aren’t looking for the God battery for 2017. Everyone seems to be looking for this right chemistry to scale with at this point. Granted, these are big automakers that could scale quickly as long their company culture is rowing in the same direction.

Tesla has their battery composition set and plan to cut 30 percent or more of costs out of their current battery price, which stands anywhere from $260 to maybe $220 kWh. Take the high end and with the cost savings, the battery pack is at $185 kWh, approximately.

That’s just over $10,000 for a battery pack for a 55kWh battery pack—assumption 30% battery cost reduction translates to battery pack. Also, my assumption above is that a Gen 3 car will be smaller and could get 220 miles with a smaller battery pack.

The rub for me is that the roadmap is in place for Tesla Motors battery chemistry and this should get them to a mass-market electric vehicle, first. Maybe other automakers are close to a new chemistry, but automotive testing and applications take time.

In the end, I’m all for the god battery sooner rather than later but Tesla Motors just isn’t waiting for it.

Tesla Full Self-Driving gets hit with some adjustments in Europe

Published

on

Tesla Full Self-Driving, which is now referred to in Europe as “Tesla Assisted Driving” (TAD), is getting hit with a handful of new changes at the hands of the Netherlands’ vehicle authority, the RDW (Rijksdienst voor het Wegverkeer).

On 3 November, the RDW announced that it has assessed and approved a set of changes to Tesla’s FSD Supervised driver-assistance system. The updates introduce the official European name TAD and impose stricter controls on the system’s speed behaviour.

The new name will appear on the in-car display, in the owner’s manual, and in all other driver-facing information. The change applies to Tesla models equipped with Tesla Assisted Driving and hardware version 4.0 (HW4) or later.

Tesla Assisted Driving expands to tenth EU country

Importantly, the RDW stressed that the name change does not alter the system’s fundamental operation: it remains a supervised driver-assistance feature that supports the driver in performing driving tasks. The driver stays fully responsible for controlling the vehicle at all times.

Beyond the rebranding, the most significant functional adjustments concern speed settings. Drivers will still be able to set a speed margin, a percentage by which the system may exceed the applicable speed limit when necessary for safety or traffic flow. However, the maximum allowable margin has been reduced from +50% to a maximum of +10%.

In addition, every time the vehicle is started, the speed-margin setting will default to 0% deviation, and other speed-related functions will be disabled by default. These changes will be delivered through an over-the-air (OTA) software update from Tesla.

Tesla requested the RDW’s review of these “minor changes.” After evaluating how the modifications were implemented and how the system behaves, the authority found no adverse or unintended effects on the system’s operation or the vehicle’s driving behaviour. Consequently, the existing type approval remains valid under the same conditions and for the same use; no amendment or extension of the approval is required.

The RDW has informed the nine EU member states that have already accepted its type approval—Belgium, Denmark, Estonia, Croatia, Latvia, Lithuania, Slovenia, Slovakia and Czechia—about the updates. Broader EU-wide approval is still under discussion within the European Technical Committee on Motor Vehicles (TCMV). Those proceedings remain confidential, and the RDW has declined to comment on them.

The approved changes align with earlier discussions involving German authorities, which had advocated both for clearer naming to avoid misleading drivers and for a tighter speed offset.

By formally incorporating these adjustments while leaving the core type approval intact, the RDW has cleared the way for Tesla to roll out the updated TAD software via OTA to eligible vehicles in the Netherlands and the other countries that recognise the Dutch approval. The system continues to function strictly as supervised driver assistance, with the human driver remaining the responsible party.

Tesla shows off Roadster ‘kickflip’ over vehicle lineup in crazy new POV video

Tesla has released a fresh point-of-view video capturing the next-generation Roadster’s headline stunt from its October 15 unveiling, giving fans a visceral look at the car as it jumps and rotates over its siblings within the company’s vehicle lineup.

Tesla posted the video on X today with the caption “POV you’re a flying car,” and the roughly 30-second clip reveals never-before-seen angles directly attached to the Roadster. It’s really unbelievable:

The sequence reveals the uncrewed prototype firing its cold-gas thrusters, lifting off the ground, and barrel-rolling fully inverted while sailing over a staged lineup that includes a Model 3, Model Y, Cybercab, Cybertruck, and Tesla Semi.

Here’s an image of it that Tesla shared right after the unveiling event for a better perspective of what you’re looking at:

There are also some other cool takeaways from the video, including the shift to the inverted-ramp demonstration. The Roadster uses its underbody suction-fan system to climb, then lock itself upside down on the ramp.

This generates multiple Gs of downforce, which then translates into the Roadster releasing these systems to enable a mid-air roll. The car then settles on its wheels gently as thruster vapor provides a perfect cushion.

All of the runs at SpaceX’s McGregor, Texas, test site, which is where the unveiling took place, were autonomous. Elon Musk stated this was a safety measure.

Tesla’s vehicle-engineering chief Lars Moravy dubbed the mid-air roll the “kickflip,” prompting Musk to quip that Tony Hawk would be proud and that the car could clear even more of the fleet. The thrusters, which use high-pressure compressed air and fast electric actuators, provide the precise, short-duration force needed for both the launch and the controlled rotation; the same hardware is intended for production versions of the higher-end Thrust and Rocket trims.

The second-generation Roadster, first teased in 2017, has been delayed repeatedly. Musk has indicated production is targeted for 2028.

While the company has yet to publish full pricing or independent performance verification, the combination of extreme acceleration, ground-effect suction, and limited flight capability has already positioned the car as one of the most theatrical EV reveals in years.

Musk has also said Tesla plans a dedicated Texas test track so future owners can experience the maneuvers themselves, far from public roads. The new POV clip simply lets everyone else feel a fraction of that experience from the car’s own cameras.

SpaceX’s Starfall just went from secret to storefront

SpaceX now pitches Starfall missions with 1,000 kg payloads, weeks of microgravity, and Starlink connectivity.

SpaceX has put up a dedicated commercial page for Starfall, its disk shaped reentry capsule, laying out for the first time what customers actually get when they book a flight. The page, live at spacex.com/starfall, pitches “affordable, routine access to microgravity” and invites companies to get in touch about flying manufacturing, research or testing payloads.

The specs are short and specific. Each Starfall mission carries up to 1,000 kg of payload, supplies 1 kW of power and connects through an Ethernet interface. Mission length is tailored to the customer, and the payload stays online the entire time through Starlink, which means researchers can pull data from an experiment while it is still in orbit instead of waiting for splashdown.

SpaceX is launching a secret spacecraft that could change how things are made in space

SpaceX is aiming the service at three markets. Biomedical customers are told they can grow stem cell organoids, replacement tissue and layered biomaterials. Pharmaceutical companies are pitched on protein and small molecule drug crystals, which form smaller and more uniform shapes without gravity driven convection. Materials science rounds out the list, with semiconductors and other next generation materials grown in vacuum and microgravity.

The page also makes clear which rocket SpaceX is counting on. “By launching on Starship, Starfall brings a reliable and scalable cadence previously unavailable to the market,” the company wrote, contrasting weeks of continuous microgravity with the seconds offered by drop towers and parabolic flights. No price or first operational flight date is listed.

The commercial push is a sharp turn from how Starfall started. SpaceX said almost nothing about the capsule ahead of its first flight in June, and nearly everything known came from FAA and FCC filings describing a disk about 10.2 feet wide and 2.5 feet tall that can return 2,200 pounds of cargo. By its second flight on the Bandwagon-5 rideshare in October, Starfall was listed by name on the mission page, though SpaceX still did not say what it carried.

Customers appear to be lining up. SpaceX said in its third quarter results that it signed three commercial Starfall missions during the quarter. On the earnings call, President Gwynne Shotwell described the capsule as providing “routine relatively low cost access to microgravity environments for scientific research, including improving our understanding of diseases like cancer and diabetes,” and said the three new missions would fly on Starship.

The branding effort extends past the website. SpaceX added a Starfall T-shirt to its online store on Monday as part of a batch of new merchandise, giving the program a place next to Starship, Starlink and Starshield in the company’s lineup.

The move also puts SpaceX in more direct competition with companies it launches. Varda Space Industries, which has built much of the in-space manufacturing market so far, flew its W-Series 7 capsule on the same Bandwagon-5 mission as Starfall in October. Varda’s capsules are roughly three times smaller than Starfall, and SpaceX controls the ride to orbit for both.

Starfall’s near term cadence depends on Starship. SpaceX is preparing for Flight 15 after completing static fires of Ship 42 and its Super Heavy booster in late October, and is aiming to catch both stages with the launch tower on that flight.
