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.

Even Ferrari swept up in latest Takata recall expansion

The scope of Takata's deadly airbag problems continues to widen. Eight manufacturers announced recalls Friday that affect more than 12 million vehicles, according to documents filed with federal regulators. The automakers include Honda, which is recalling 4.5 million units, Fiat Chrysler with 4.3 million, Toyota with 1.65 million, and Subaru, which is recalling almost 400,000. Some of these cars include the Saab 9-2x and Pontiac Vibe that Toyota and Subaru made for General Motors. Mazda will recall 730,000 vehicles and Nissan has 400,000 affected units. The smallest numbers were posted by Mitsubishi, with 38,000 Lancers manufactured from 2006 to 2007, and as a noteworthy high-end manufacturer, Ferrari is calling back 2,800 vehicles. These are all US-market cars. Beyond America, the Japanese Transport Ministry has announced seven million additional vehicles will be recalled, which means 19.6 million vehicles across the globe are affected by recalls announced. The defects have been traced to an insufficiently manufactured airbag inflator, which lacks a drying agent that would prevent the inflators from deteriorating over time. Thirteen deaths have been linked to the faulty airbags, which have become unstable and are prone to exploding and showering vehicle occupants with lethal amounts of metal shrapnel. A private equity firm, KKR & Co., has been named in a possible buyout of the struggling Takata.

Japanese automakers kick in $800k for new charging-station company

Cynics may say that gathering $800,000 (total) from four of Japan's largest automakers is merely a rounding error. Still, Toyota, Nissan, Honda and Mitsubishi, along with the Development Bank of Japan, are putting those funds to good use. So, that's something. Last week, those five entities officially founded Nippon Charge Service LLC. The company was established to promote plug-in vehicle charging installations across Japan and the automakers seeded it with 80 million yen, or about $786,000 US. Those funds will be used to help business owners deploy charging stations at convenience stores, highway-side locales and other locations that will make it easier for plug-in vehicle drivers (of Toyotas, Hondas, Mitsubishis and Nissans, obviously) to get their juice. The automakers first announced they'd collaborate last year, when they said they'd work with the Japanese government to more than triple the country's publicly accessible chargers to about 17,000 units. No targets were disclosed as far as how many charging stations would be deployed this time out, but, in a move similar to the EZ Charge system in the US, Nippon Charge Service will also have universally-accepted charging cards available by the end of the year to drivers all of those brands' plug-in vehicles to make the charging process a little more seamless.

Honda Motor Co., Ltd. Mitsubishi Motors Corporation Development Bank of Japan Inc. TOKYO, Japan, May 30, 2014 - Toyota Motor Corporation, Nissan Motor Co., Ltd., Honda Motor Co., Ltd., and Mitsubishi Motors Corporation jointly established a new company, Nippon Charge Service, LLC, on May 26 to promote the installation of chargers for electric-powered vehicles (PHVs, PHEVs, EVs). The goal is to help build a charging network that offers more convenience to drivers in Japan. The new company will promote the installation of chargers, for the good of society and to expand the use of electric-powered vehicles. Related industries are also expected to benefit.
