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: LA Auto Show may feature updated Cadillac ELR, Uber expands Chicago HQ

A Kentucky man has converted his 1939 Dodge pickup to an electric vehicle. Al Gajda of Lexington built the electric truck, which he now uses as his daily driver. "I take advantage of any excuse to drive it; just banging around town, errands, short runs on the interstate, delivering my granddaughter to school in the morning," he says. It is powered by a lithium-ion phosphate battery, which is mounted in a wooden box on the truck bed, and gets about 100 miles per charge. Read more at the Lexington Herald-Leader. Elon Musk will speak at the Automotive News World Congress in January. The Tesla CEO is a featured speaker for the program, "Setting the Pace in a Thriving Market." The event takes place in Detroit, which could lead to an interesting mix of people in the audience, and Musk will speak on January 13. Read more at Automotive News. Production of the Toyota Rav4 EV has ended. The shipment of the final Toyota EVs concludes Toyota's deal to source batteries from Tesla. Of the 2,600 Rav4 EVs to be produced, there are probably just a few hundred left to be sold, most of which are likely to be gone by the end of October. Read more at Inside EVs. Cadillac will likely show an improved version of the ELR at the Los Angeles Auto Show in November. The 2016 ELR will include unspecified "engineering enhancements," according to Cadillac spokesman David Caldwell. There will be no 2015 model, as the 2014 model will be sold until the 2016 ELR goes on sale in the first half 2015. Read more at Edmunds. Uber executives, along with Illinois Governor Pat Quinn, have announced a major expansion of the ride-hailing company's Chicago headquarters. Uber also plans to add 420 jobs by the end of 2016. "Uber's new expanded headquarters will allow the company to continue its rapid growth and serve its riders and drivers throughout Illinois," says Governor Quinn. Last month, Quinn vetoed legislation that would have put restrictions on companies like Uber in the state. Read more in the press release below. Governor Quinn and Uber Announce Major Chicago Headquarters Expansion Innovative Ridesharing Company to Add 420 Jobs by End of 2016 CHICAGO, Sept. 29, 2014 /PRNewswire-USNewswire/ -- Governor Pat Quinn and Uber executives today announced that the ridesharing giant is moving forward with creating 420 new jobs by the end of 2016 in a major expansion of its Chicago regional headquarters.

Owner reflects on his $20.91 Toyota unintended acceleration settlement check

Where General Motors and Takata have grabbed many auto safety-related headlines this year with their problems with ignition switches and airbag inflators, a few years ago, a similar sort of scrutiny fell on Toyota for unintended acceleration. After multiple settlements with various parties totaling billions of dollars, the issues seem largely behind the Japanese automaker now. Owners are actually starting to receive their money, but it isn't exactly breaking the bank. Payouts are expected to be between $37 and $125 per person. Computer science student Jonathan Sourbeer received a check for just $20.91, and he considers what that money actually means in an op-ed in The Wall Street Journal. Sourbeer's biggest gripe is that the roughly 85 lawyers in the case are receiving $227 million in attorneys' fees and expenses, while the 25 primary plaintiffs and class representatives receive a total of just $395,270. According to the Frequently Asked Questions about the settlement, Toyota set up a $250 million fund to pay affected owners, as well. The money isn't for injuries or damages but for alleged economic loss to the vehicles. However, Sourbeer says he feels no personal suffering and still has the same car. In addition to the settlement, the automaker obviously has its own legal fees to deal with, as well. Sourbeer wonders how this is all going to affect Toyotas in the future. Obviously, the money has to come from somewhere, and it likely gets amortized over the company's vehicles in the coming years to add a few dollars to each one. That puts the problem back onto customers. Anyone involved in a class-action suit has likely seen this happen first hand. The lawyers take a large chunk of the money, and the rest is distributed in tiny morsels to those actually affected. Unfortunately, Sourbeer offers no solutions beyond saying the system needs to change.
