How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.

Is this the fourth-gen Toyota Prius? [w/video]

A new video has appeared on Prius Chat of a camouflaged hatchback that just might be the next Toyota Prius. There's nothing here that concretely proves what we're looking at is the fourth-generation model of the world's best-selling hybrid, but upon first glace, the Prius guess makes sense. In an ironic twist, the car was caught because it needed gas. Prius Chat user Savior1974 says that the car was spotted on a drive between Las Vegas and California in Baker, CA. Savior1974 wrote, "As we are leaving we see a car dressed as it were being road tested. Upon further inspection it looks like it might be a Prius. I took a quick video as I drove by but it's not the best quality." The launch of the next-gen Prius has been delayed because of more work that was needed to make the car more efficient and to improve the styling. Work on getting the Prius to work well with the new Toyota New Global Architecture platform also needed more time. Last summer, we heard rumors that the Prius' new design would be finalized in November 2014. There are a few points to keep in mind that might point to this being something other than the next Prius. First, the all-black, electrical-tape-style camo is not the normal wrap that the Toyota Technical Center uses for testing (compare with these early shots of the Prius C and these other fourth-gen Prius spy shots). Second, the Baker grade between Las Vegas and California (where the video was shot) is full of vehicles being tested by any number of automakers. Nonetheless, the lines of this car do look like a Prius, so we leave you with a gallery of stills from the video and, of course, the video itself, above.

Recharge Wrap-up: Honda Grace hybrid goes on sale in Japan, Daimler spends 100M euros on batteries

The Mercedes-Benz S-500 Plug-In Hybrid has earned an Environmental Certificate from the TUV Sud technical inspection authority. The award is based on a lifecycle assessment of the vehicle. This includes the ability to reduce CO2 emissions by 43 percent through charging, and by 56 percent if charged using hydroelectricity. Read more in the press release below. Daimler is expanding its production capacity for lithium-ion batteries. The company is investing around 100 million euros in its subsidiary Deutsche ACCUmotive, who will provide batteries for the electric Smart Fortwo and Forfour, as well as various Mercedes-Benz models. By the end of the construction, Deutsche ACCUmotive will have quadrupled production and logistics space since 2011. Read more in the press release below. Honda has begun sales of its Grace hybrid sedan in Japan. The Grace is based on the Honda Fit and uses the automaker's Sport Hybrid i-DCD system. It comes in front- and four-wheel-drive versions and uses a seven-speed DCT with built-in motor. The Honda Grace starts at the equivalent of about $16,500. Read more in the press release below. Honda has begun operation of its wind farm in Brazil. The farm consists of nine wind turbines, expected to produce about 95,000 MWh of electricity per year, which is on par with Honda's consumption for automobile production in the country. Honda is aiming to cut its CO2 production by 30 percent by 2020 compared to 2000 levels. Read more in the press release below. Toyota has won the 2014 World Endurance Championship's Driver and Manufacturer categories with hybrid technology. Toyota celebrated the win after the final race in Sao Paolo, Brazil. Toyota uses the same hybrid technology in its racing cars as it does in its production vehicles. Read more in the press release below. Controlled Power Technologies and other groups are calling for an international 48-volt electrical standard for vehicles. The groups called for the standard at the International Conference Automotive 48 V Power Supply Systems, saying that the 48V standard for mild hybrids would help make the systems more affordable. This will make it easier for automakers to meet the more stringent CO2 standards anticipated in coming years along with the introduction of the World Light vehicles Test Procedures.
