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.

At least 15 states jockeying for Toyota and Mazda factory jobs

Just a few weeks ago, Mazda and Toyota announced a partnership that would lead to an all-new $1.6 billion plant here in the United States. The plant will build EVs and is expected to employ roughly 4,000 people directly while creating thousands of indirect jobs through suppliers, shipping and more. The Detroit Free Press reports that as many as 15 Midwestern and Southern states are understandably interested in striking a deal with the automakers. Most of the states already have ties to the auto industry. While the Midwest has traditionally been home to auto manufacturing in the United States, in the past 25 years or so, the South has made a big push, offering tax incentives and a union-free workforce. Alabama alone is home to facilities from Honda, Hyundai, Mercedes-Benz and Toyota. Others house a burgeoning tech or manufacturing industry ripe for the picking. Freep breaks down the pros and cons for each state, with much of the focus being on supply chains and a reliable and plentiful workforce. The latter is of particular concern in states like Alabama and Michigan that already have a big auto industry. Toyota may feel those areas have already been tapped for talent. Most of the states are along or adjacent to Interstate 75 and its extended roots, so others like Texas and Iowa will have to fight hard if they want this facility. It's only been a few weeks, though. With manufacturing jobs in such great demand and elected officials eager to show they're seeking them for their states, it wouldn't be surprising if a few more joined the fray.

The List #0025: Compete in the Rallye Aicha des Gazelles

The Rallye Aicha des Gazelles du Maroc is an annual all-women's off road rally in the Moroccan desert. Teams of two must navigate between various checkpoints using only a rudimentary map and compass. Host Jessi Combs pairs with driver Nicole Pitell to take on the grueling, nine-day rally race, as co-host Patrick McIntyre tracks their progress in the desert heat. "The thing that's going to drive me nuts today is that we can't help," Patrick tells Jessi moments before she departs on a two-day marathon leg. "We can do nothing but watch." For Jessi – an experienced off-road racer in her own right – navigating the Sahara in the team's Total Chaos Tacoma is a challenge unlike any other. "You know when you've ever really, truly been lost and you don't know where you are and you start to getting that anxiety feeling? Now, take that and put it into the middle of Morocco," explains Jessi. "And we're just this lost, little spec, and it's our responsibility to get us un-lost and back to safety." How will Jessi fare among the newcomers class and ten US teams in attendance? Watch as she checks "compete in the Rallye Aicha des Gazelles" off of her list. Have an RSS feed?
