Toyota follows Tesla, makes hydrogen patents open source

Back in June, Tesla said All Our Patents Are Belong to You as it released its electric vehicle patents to the world. CEO Elon Musk said at the time that patents, "serve merely to stifle progress, entrench the positions of giant corporations and enrich those in the legal profession." Despite some disagreement on which gasoline alternative (electricity or hydrogen) will power the automotive future, it looks like the folks over at Toyota like the idea of making advanced technology easier for others to get their hands on. Last summer, Tesla said that it would, "not initiate patent lawsuits against anyone who, in good faith, wants to use our technology." In an announcement today at CES, Toyota said it would let "automakers who will produce and sell fuel cell vehicles, as well as ... fuel cell parts suppliers and energy companies who establish and operate fueling stations" get free access to 5,680 fuel cell related patents around the world. That means if you're interested in building your own Mirai H2 car, you can now get some of the instructions. There's a catch, though, in that Toyota's H2 vehicle patents will only be free, "through the initial market introduction period, anticipated to last until 2020." Patents about making and selling hydrogen will be free "for an unlimited duration." Toyota's Senior VP of Automotive Operations, Bob Carter, said that, "At Toyota, we believe that when good ideas are shared, great things can happen. ... By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically." Toyota generates a lot of patents each year – 1,491 in 2012 in the US alone, for example – but it did not see fit to make them all open to competitors. While we don't know for sure how many automakers have decided to use Tesla's patents since they were made public, but it appears that interest in the technology is muted. We'll have to wait and see how the industry reacts to the influx of H2 information. We hope this will be one of the topics Musk addresses in his Reddit AMA later today.

NHTSA investigating 30,000 Toyota Camry Hybrids for brake assist problems

Older model Toyota Camry Hybrids are under investigation by the US National Highway Traffic Safety Administration (NHTSA) for potential braking problems. Enough complaints have poured into the NHTSA website that the agency is now taking a look at the problem, which could affect around 30,000 vehicles from the 2007 and 2008 model years. According to Reuters, 59 complaints have been submitted revolving around an "intermittent loss of assisted braking" which means the car takes longer to stop. Interestingly, the rate of complaints is increasing. Toyota is reportedly cooperating with NHTSA and there has not yet been an official recall on the Camry Hybrids. In 2006, Toyota said Brake Assist was "an electronic function that senses an emergency stop and applies increased braking power once the driver touches the brake pedal." When Toyota unveiled the 2007 Camry Hybrid, it proudly stated that the new Brake Assist function would be standard. Other Toyota hybrids have had problems with their brakes in the past, including the 2010 Prius and Lexus HS 250h hybrid. You can read some of the complaints about Brake Assist in the Camry Hybrids to the NHTSA here. People are saying that the "Check VSC" lights can come on before the brakes loose some of their power and a lot of them are being quoted repair costs of over $3,000 by Toyota dealers.

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.
