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.

Toyota recalling 10k vehicles to fix wiper switches

Toyota has announced a voluntary recall covering approximately 10,000 cars in the United States. Affected models include the 2013-14 Camry and Camry Hybrid, 2013-14 Avalon and Avalon Hybrid, and the brand new 2014 Corolla.
The problem, as Toyota explains it, is that, "During manufacture of the wiper switch assembly in the involved vehicles, certain contacts on the switch terminal could have been manufactured incorrectly." This could lead to a short in the circuit when the wiper switch is moved between "off" and "mist," and thus, cause the windshield wipers to stop working. Not good.
Toyota will contact owners via first class mail, and the vehicles can be repaired at dealerships, free of charge. Have a look below for the automaker's official statement.

Toyota confirms i-Road electric trike for production

The wacky, three-wheeled Toyota i-Road we saw in Geneva earlier this year will be heading to production. But before you run down to your local Toyota dealer looking for one of these all-electric "personal mobility" vehicles, chances are, you'll never actually see one unless you visit Japan.
Announced at the Combined Exhibition of Advanced Technologies (CEATEC) expo last week, Toyota said that the i-Road would be used as a part of the Ha:Mo car-sharing system in Japan. Weighing in at around 661 pounds, with a 28-mile-per-hour top speed and a two-passenger seating arrangement, the i-Road seems more like a fully enclosed scooter than a car, but it does offer a 30-mile driving range and has a nifty articulating front suspension that leans into corners. As for Ha:Mo, Toyota says that the number of cars in the program will increase from 10 prior to October 1 to 100 by the middle of this month, and the number of stations will almost double from 13 up to 21. Toyota has more details about the car and Ha:Mo in the press release posted below.
