Tesla’s Battery Strategy Receives Little Discussion, But It Should

Published

on

Tesla released news last month that its new Roadster battery pack upgrade would use cells manufactured by South Korea-based LG Chem, instead of Panasonic, its long-standing battery cell provider and investor in the Gigafactory.

The automotive media riffed on a possible “controversy” between Panasonic and Tesla Motors, as it headed into 2016. After all, LG Chem sells batteries to a lot of companies notably GM for its Volt and upcoming Bolt vehicle.

Tesla Model S P85 battery pack

 

Last year, Forbes was drooling over the “holygrail” of batteries from Ann Arbor, Michigan-based Sakti3 and its solid state lithium battery. The article hyped possible breakthroughs for the EV industry, such as a $100 / kWh battery cells, but mainly touched on its application towards consumer products. Soon after, U.K. vacuum maker Dyson announced its plan to purchase the battery startup for $90 million to help commercialize the battery technology for consumer purposes.

What gets lost in the post-Model X reveal and Autopilot frenzy is that Tesla’s battery strategy is spot on, much like that of Nissan’s partnership with NEC (also known as Automotive Energy Supply Company). The way to shave cell and battery pack costs in 2015, and going forward, is vertical manufacturing for lithium-ion battery chemistry. And, this seems to get lost lately with all the talk around self-driving vehicles and forward guidance on sales numbers.

GM Strides

During Tesla's latest earning's call, Musk and JB Straubel commented on the recent claim by GM that they would have an "industry-leading" $145 per kWh cell cost.

Musk said:

“I mean we're constantly agonizing about cell cost and pack cost, and we don't think anyone is on a path to be even close to us. If they are, I would be the first to congratulate them.”

Sounds like confidence with his team and battery strategy, and it resonates with me. Battery chemistry break-throughs for automotive use seems to be a long way off, with most new battery materials still being tested in the lab and no pilots really anywhere.

Argonne National Laboratory, outside of Chicago, recently released the “mid-term” results of its battery program to create “a game-changing next generation battery to transform the transportation sector” but there’s nothing on the cusp for advancement in battery chemistry. Their R&D has given insight to how dendrites behave, and how batteries degrade over time, but no breakthroughs on battery chemistry half-way through its five year study.

Getting back to Tesla, they hired lithium-ion battery researcher and professor Jeff Dahn, from Dalhousie University in Nova Scotia earlier this year. According to Fortune, Dahn is currently working on a project funded by 3M and the Natural Sciences and Engineering Research Council of Canada to develop longer-lasting, lower cost lithium-ion battery cells. Dahn will joint Tesla Motors in June of 2016.

The race is on to make lithium-ion cheaper but it sure doesn’t look like there’s any “other” battery chemistry on the backstretch. While the battery breakthrough hype has died down, it comes down to two automakers (maybe GM too) committed to reducing battery costs by vertically integrating it into their manufacturing footprint. To my knowledge some automakers haven’t committed yet, like Volkswagen and Toyota. Wonder how that will play out?

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Published

on

Tesla has officially launched the Model Y L in the United States and Puerto Rico for $61,990. It is the longer-wheelbase version of the Model Y, and has been available in China since last year.

Tesla brings the Model Y L to the U.S. just months after it phased out the only pure SUV in its lineup, the Model X. It is slightly longer than the Model Y configurations that are already available in the U.S., and features a three-row, six-seat setup with Captain’s Chairs being among the many features that make this a truly fantastic offering.

The Model Y L is priced competitively at $61,990, and features 325 miles of range and a 0-60 MPH in just 4.4 seconds.

Tesla also added a handful of new features that are not available in even the Premium Model Y. Here’s a full list of its features:

  • Heated/Ventilated Front Seats with Powered Thigh Cushion
  • Heated/Ventilated Captain’s Seats in Second Row with Powered Armrests & One-Touch Fold
  • Heated Third-Row Seats with Power Recline, One-Touch Fold & Child Seat Anchors
  • Improved Airflow, Increased Efficiency, More Range
  • 89 cubic feet of trunk space
  • Upgraded Acoustic Glass and Suspension to Minimize Road Noise
  • Adaptive Damping for a Smooth, Stable Ride
  • Staggered Tires for Enhanced Grip
  • Larger Tailgate for Better Rear Visibility and Bigger Windows Overall
  • 16″ First Row and 8″ Second Row Touchscreens
  • 19-Speaker Immersive Tesla Audio
  • 50W Wireless Charging Pads with Active Cooling and Charging Ports for All Other Seats
  • FSD Supervised and Integrated Grok AI

Tesla is also delivering these first units as a “Launch Series,” which comes with additional features, such as:

  • Door Trim Puddle Lights
  • Suede Dashboard Wing
  • Exterior and Interior Badging
  • Floor Mats
  • Sill Plates

The launch of the Model Y L in the U.S. marks a huge offering from Tesla to U.S. consumers. People have been calling for Tesla to bring a larger car to the U.S., and it needed it more than ever now that the Model X is gone.

It is a huge accomplishment for Tesla to get the Model Y L to the U.S., and after reporting strong deliveries today, it will be interesting to see how this car impacts future quarterly delivery reports.

Deliveries for the Model Y L “Launch Series” are slated for September or October of this year.

Tesla just told us twice that Model Y L is coming to the U.S.

Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.

The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.

The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.

With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.

However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.

Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.

Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.

Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.

Tesla is using vehicle microphones to improve build quality: here’s how

Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.

It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.

As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.

The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.

It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.

Tesla’s ‘megacasts’ are key to massive build quality improvements

While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.

This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.

Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.
