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. Read more in the press release below. 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.

Heavily updated 2015 Toyota Camry to bow in New York

Looks like the new, "more emotional" Toyota Camry designer Kevin Hunter talked about back in January is going to arrive very soon, with news that Toyota's bread-and-butter sedan will be getting an update in just a few weeks time at the 2014 New York Auto Show.
"On April 16 at the New York International Auto Show, we will make an important announcement about America's best-selling car, the Toyota Camry," said Curt McAllister, Toyota product news manager, in an emailed statement. Considering the high-profile nature of the NYAS - not to mention the competition that will be shown there - it makes sense that Toyota would choose to unveil something as significant as a major refresh at the Javits Center.
We wish we had more to tell you than this, but unfortunately, that's about all we've got to go on at this time. Of course, we'll have much more for you during the lead up to NYAS, including any leaks of the refreshed Camry. Stay tuned.

Recharge Wrap-up: Toyota FCV wears silver, Foxconn's $15K EV, solar power at GM

The Toyota FCV made its North American debut at the 2014 Aspen Ideas Festival, and this time it's not sporting its usual blue sheet metal. This silver paint job shows a bit more contrast. Certain features stand out a bit more, especially the black strip that wraps around the grille and down the sides of the hood to the mirrors. This is the production version of the car's exterior, which will go on sale in California next summer. Toyota also had its Driver Awareness Research Vehicle, DARV 1.5, on display in Aspen. DARV 1.5 uses technology to decrease driver distraction and measure driver behavior to provide a safe driving score. See more of both cars in our image gallery. Taiwan's Hon Hai Precision Industry (also know as FoxConn Technology Group) says it is planning to build electric cars that will cost just $15,000, according to The China Post. The world's largest electronics maker, which assembles mobile devices for Apple, promises that the cars will be highly connected. "When integrated with cloud computing, the Internet, smart traffic and smart cities in the future, people will be able to drive more easily and reduce car accidents more efficiently," says Hon Hai chairman Terry Gou. At a shareholder's meeting, Gou didn't comment on production timing or other details about the cars, nor would he answer questions about possible cooperation with Tesla Motors. Hon Hai made headlines in recent years after a series of employee suicides, which led the company to raise worker wages and install anti-suicide netting on its buildings. EV advocates in Illinois took a 500-mile road trip to help temper range anxiety in potential buyers, says the Chicago Tribune. The demonstration, organized by the Illinois Green Economy Network, meant to show people that they can use electric vehicles to drive long distances without getting stranded with a dead battery. The drive began near Carbondale and traveled to 11 different community colleges with charging stations before terminating in Grayslake. Illinois has about 5,000 registered electric vehicles, and 450 public and private charging stations. General Motors is building three acres of new solar arrays to produce an expected 400,000 kilowatt-hours of renewable energy per year. The new arrays at GM's Swartz Creek processing center and Flint engine plant will be completed this fall, contributing to the company's 38 megawatts of solar power from facilities around the world.
