Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

Toyota begins shipping Le Yaris to America

Our tiniest Toyota (Scion iQ notwithstanding) is about to get a little French flair. The Japanese automaker announced Thursday that its Toyota Motor Manufacturing France facility would begin building Yaris models destined for North America - specifically, the United States, Puerto Rico and Canada. This will mark the first time in history that Toyota has exported vehicles to North America from Europe.
Initially, Toyota will export roughly 25,000 Yaris models to North American markets from France each year. In order to handle this additional production, Toyota Motor Manufacturing France has invested 10 million euro into its French facility.
Despite being somewhat of a snooze-fest (it's a car!), the Yaris carries on in North America with a 106-horsepower 1.5-liter four-cylinder engine, with prices starting at $14,370 for the three-door and $15,395 for the five-door, not including $795 for destination.

Recharge Wrap-up: Minnesota first to require biodiesel, maglev in Israel, Toyota FCV in Aspen

A new Minnesota law that requires biodiesel blends goes into effect in just a few days, says KELO. Diesel drivers in Minnesota will be pumping soybeans into their tank beginning July 1. Every year, diesel will be sold as a B10 blend (ten percent biofuel) from April through August, and will scale back to a cold-hardy B5 blend from September through March. The biofuel largely comes from soybean crops grown within Minnesota, and the biodiesel industry pumps more than $900 million into the state economy every year. According to the National Biodiesel Board, using the B10 and B5 blends will reduce greenhouse gas emissions by 1,342,000,000 pounds every year. Minnesota is the first state to require diesel to be sold as a biofuel blend. In Japan, Isuzu Motors and Japanese biotech venture Euglena are teaming up to create biodiesel using algae, according to Bloomberg Businessweek. The goal is to create a new type of fuel that doesn't need to be mixed with light oil to be used in engines. "As long as we use light oil for diesel engines, emissions of carbon dioxide are inevitable," says Isuzu president Susumu Hosoi. Euglena has also been using algae to develop jet fuel with airline operator ANA Holdings. Isuzu and Euglena hope to have the new biodiesel developed by 2018. Aerial maglev transportation is coming to the campus of a defense contractor in Tel Aviv, Israel, Wired reports. The SkyTran personal rapid transit system uses small pods on an elevated magnetic track to move people from place to place. The pilot program will see SkyTran come to the corporate campus of Israel Aerospace Industries as soon as next year. The pods are hailed by phone, and carry passengers along the magnetic rail system at speeds of up to 44 miles per hour. The passive magnetic system levitates the pod attachment a centimeter above the rails, while a burst of electricity propels the pod forward. If the test at the campus goes well, SkyTran could spread to Tel Aviv at large, moving up to 12,000 people per track per hour with top speeds of 150 mph. The pre-production prototype of the Toyota FCV will make its North American debut at the 2014 Aspen Ideas Festival on Friday, June 27. The hydrogen car's finished exterior was revealed in Japan on Wednesday along with its nearly $70,000 price tag. It will go on sale in Japan by April of next year, and will come to Europe and California in the summer of 2015.
