Almost a year into his new research partnership with Tesla, battery researcher Jeff Dahn has been hitting the talk circuit presenting some of his team’s recent progress. We reported last week on his talk at the International Battery Seminar from March and now we have a talk from him at MIT this week.
He went into details about why Tesla decided to work with his team and hire one of his graduate students, but he also announced that they have developed cells that can double the lifetime of the batteries in Tesla’s products – 4 years ahead of schedule.
Update: Dahn reached out to clarify that the cells in question were tested in the lab and they are not in Tesla’s products yet. expand full story

Historical data from Tesla’s current battery packs show about 5% capacity degradation after 50,000 miles (80,000 km) and the capacity levels off for about 150,000 more miles before hitting 90% capacity.
Those are already pretty good results, but Tesla aims to do better with Jeff Dahn, a renowned battery researcher and the leader of Tesla’s research partnership through his battery-research group at Dalhousie University.
The scientist and his team recently unveiled their latest research on a new chemistry that could enable even more cycles without significant degradation. expand full story

A few years back, there was a lot of talk about Tesla potentially using a metal-air/li-ion hybrid powertrain to enable a longer range and faster charging in future vehicles. There’s no doubt that the company worked on such a system since they applied for several patents related to the tech, but that was mainly back in 2010 when they were still very much in the heavy development work for the Model S.
At this point, it looks like Tesla is very committed to li-ion batteries and metal-air doesn’t seem to be on the map anymore, but the company was recently granted another patent related to emerging battery technology. expand full story

For the past year, Tesla has been guiding “by the end of the year” for the start of battery cell production at the Gigafactory. The end of the year has come and gone, but Tesla didn’t confirm the start of production.
As it turns out, Tesla, and its battery partner Panasonic, started production of cells for qualification at the plant in December, but today, it confirmed the start of “mass production” of the new battery cell, which will enable several of Tesla’s new products, including the Model 3. expand full story

Considering most specs about Tesla’s batteries are kept secret, it can sometimes be difficult to understand the company’s competitive advantage in this space. Experience and data are certainly important factors. Tesla was the first company to treat battery cells as a commodity and build large battery packs using thousands of common cylindrical li-ion battery cells. That was over a decade ago. expand full story

We don’t hear a lot about Tesla’s battery swap program anymore. We are told that it is still alive, but on the back-burner as Tesla’s EV infrastructure team is focusing on accelerating the rollout of Supercharger stations ahead of the Model 3 coming to market next year.
The use case for regular Tesla owners is not really attractive versus the Supercharger, but battery swap could make a comeback with special stations for ‘Tesla Semi’ or private stations to accommodate large commercial fleets of Tesla vehicles. Tesla recently hired Audi’s NA commercial account manager to lead a new B2B push for Tesla in “fleet management, rental, government/public sectors & corporate enterprises.”
Tesla could be looking to have a more important presence in commercial fleets and battery swap makes more sense when it’s important that your vehicles stay on the road. Same goes for freight with the upcoming ‘Tesla Semi‘.
In the meantime, we now get a new look at Tesla’s battery swapping magic through newly released technical drawings from a patent application. expand full story

What is Tesla’s core technology advantage over competitors? Does it even have one? Those are questions that often come up when discussing Tesla’s lead in the electric vehicle sector. Since Tesla open-sourced its patents, some suggested that its technology advantage is virtually nonexistent since competitors could simply use it, but it’s not as simple.
While Tesla’s patents are indeed opened for use in electric vehicles as per its ‘patent pledge’, Tesla is still keeping some trade secrets and the company is fairly secretive about some of its development and manufacturing processes, especially when it comes to batteries, which could very well be Tesla’s core technology advantage led by its co-founder and CTO, JB Straubel. expand full story

While Tesla has been manufacturing battery packs at the Gigafactory for its energy storage division since last year, new battery cell production is expected to be the real hallmark of the giant battery factory and it has yet to happen.
Panasonic, Tesla’s strategic partner at the plant, is in charge of the cell production inside the facility and it is expected to begin the process by the end of the year. Now we learn that Panasonic is “gearing up for significant growth” at the Gigafactory and it will host a special invitation-only hiring event on location next week to for “positions in advanced manufacturing”. expand full story

Last week, we reported on Tesla starting to take delivery of important quantities of battery cells from a new supplier: Samsung SDI. At the time, we contacted Tesla to know what the cells will be used for, the company declined to comment, but we speculated that it could be used for ‘Tesla Energy’ products.
Now prompted by a Reuters report yesterday citing Samsung SDI sources claiming that they are in negotiation with Tesla to supply batteries for its cars, Elon Musk has confirmed that Panasonic will be exclusively supplying cells for the Model 3, S and X. expand full story

‘Lithium’ battery capacity degradation is one of the main concerns of electric vehicle buyers and potential buyers. Since the resurgence of electric cars is relatively recent, meaningful long-term data on large battery packs is fairly rare. Only Tesla has battery packs with a capacity higher than 30 kWh on the road in any significant number and they only have been in operation for a few years (Roadster aside).
But a few Tesla owners have accumulated impressive mileage on their vehicles and the data provides an interesting look into potential battery capacity degradation. expand full story

Tesla often said that the Model 3’s $35,000 price tag was dependent on the company achieving its battery cost reduction goals at the Gigafactory. Recently, Tesla officials said that the Gigafactory should no longer be seen as a constraint in the Model 3 supply chain and that the company is confident in its capacity to start producing battery cells.
The factory was first presented as having a full annual output capacity of 35 GWh of battery cells and 50 GWh of battery packs – with the difference in cells being imported from other manufacturers, like Tesla’s Gigafactory partner Panasonic, but also other possible cells suppliers.
Now it looks like Tesla is looking to South Korea to diversify its battery cell supply chain for the Model 3. expand full story

Tesla’s Battery Swap Program impressed a lot of people when it was unveiled back in 2013. It probably was one of Tesla’s most well-organized presentation. Elon Musk narrated a live test on stage during which the company performed two automated battery swaps while live-streaming a Tesla employee filling up a gasoline car.
Despite the impressive nature of the system, Tesla launched the program very carefully and it took over a year before it opened its first “pilot facility” in Harris Ranch, California. Only a select few Model S owners were allowed to participate in the program and swap battery packs. expand full story

Acciona, a Spanish conglomerate in renewable energy and infrastructure, created last year the first team to compete at the Dakar rally with an electric vehicle. Unfortunately, they didn’t last long, but they are coming back for Dakar 2016 and they feel more confident than ever after coming out of the Morocco Rally last month as the first team to finish it with an electric vehicle.
The company seriously upgraded the vehicle this year with a focus on efficiency and a brand new battery pack. At Dakar 2015, Acciona’s car could achieve 125 miles (200 km) on a single charge with a 140 kWh battery pack under the race’s difficult road conditions. The upgraded car has a 150 kWh pack, which is only a 7% increase, but the team says it can now travel 217 miles (350 km) on a single charge under the same racing conditions, which is a 75% increase. expand full story
