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.

Recharge Wrap-up: Couple wins Toyota Mirai; Tesla Gigafactory wages reported

A couple who won a Toyota Mirai at the Los Angeles Auto Show are among the first people to own the new fuel-cell sedan. Marianne Ellis bought the winning ticket - auctioned off by the Environmental Media Association to fund environmental programs - as a possible 30th anniversary gift for her husband, David. The excited couple picked up their ceremonial keys at the LA Auto Show on Wednesday. "For us, it's about being at the cutting edge of change," says Marianne Ellis. "It's a chance to support environmental causes and clean energy, while showing it's possible to make a car like this part of your lifestyle." The Mirai will go on sale in California in the fall of 2015. Read more in the press release below. The salaries for 6,500 full-time employees at Tesla's Gigafactory battery production facility have been reported. According to the Reno Gazette-Journal, the 4,550 production associates and 200 material handlers will be paid $22.79 an hour. 460 equipment technicians and 360 quality technicians will get $27.88 an hour. 930 engineers and senior staff will earn $41.83, or $87,000 a year. Tesla plans to staff 6,500 people at the Reno, Nevada-based Gigafactory by 2020. Read more at the Reno Gazette-Journal or at Teslarati. The National Biodiesel Board (NBB) has elected its governing board members. The board leaders include Sprague Operating Resources Chairman Steven J. Levy, Minnesota Soybean Processors Vice Chair Ron Marr, American Soybean Association Treasurer Mike Cunningham and Nebraska Soybean Board Secretary Greg Anderson. NBB also filled four more spots on the board, discussed federal policies, began program planning and recognized outstanding member involvement in the biodiesel industry.

The DOE calls electrolysis, photoelectrochemical, biological and solar-thermochemical key areas of hydrogen production and has made advances in each. The DOE is looking into technological advancements in making the clean fuel and ways to reduce production costs. The DOE has also outlined various plans for the 2015 fiscal year with regard to advancing hydrogen technology, with the goal of getting hydrogen prices in line with other fuels.

Toyota launches updated Verso-S in Europe

Globally, the Toyota Yaris has bred more variants than we can shake a stick at. It's been known in different markets as the Vitz, the Platz, the Bella, the Vios and, to us, as the Echo. The first-generation model bred a small cargo van called the Yaris Verso - a mini minivan riding on the shortest wheelbase in its class - which was renamed the Verso-S for Europe and alternatively known as the Space Verso, the Ractis, the Ractis Verso and even the Subaru Trezia in certain markets. And now Toyota has launched a revised version of its Verso-S in Europe.
Arriving as a mid-life facelift after three years on the market, the new Toyota Verso-S has been reinterpreted through the "Keen Look" design language that's been distinguishing the latest generation of Toyotas, particularly in the European market. That means new projector-beam headlights and LED daytime running lights, a reshaped grille with chrome surround, more LEDs around back, a fresh set of 16-inch alloys and new color options.
The interior has likewise been spruced up with new trim and color choices, as well as a tire pressure monitor fitted as standard. There's a new touchscreen display with more connectivity options, upgraded nav and a rearview camera as well. Since Toyota's made no mention of engine upgrades, until we hear back, we have to assume the 1.3-liter inline-four and 1.4-liter diesel engines carry over unchanged with the buyer's choice of either a six-speed manual or continuously variable transmission.
