Toyota's Lentz says fuel cells are the future, not EVs

Toyota is not bullish on EVs. That comes from the company's North American CEO, Jim Lentz, who said the company will focus not on electrification, but on continued hybridization with a long-term focus on hydrogen fuel cells.
Lentz questioned the long-range ability of EVs, saying that Toyota feels "there are better alternatives, such as hybrids and plug-in hybrids, and tomorrow with fuel cells." Lentz spoke about Toyota's focus on hydrogen following Forbes Brainstorm Green conference and barely a week after a battery deal between Tesla and Toyota ended, according to Automotive News.
That deal provided for 2,500 battery packs for the Rav4 EV. While valuable to Toyota, the deal "was never about open-ended volume," Lentz said. "It was time to either continue or stop. My personal feeling was that I would rather invest my dollars in fuel cell development than in another 2,500 EVs."

Toyota hydrogen vehicle visits CES, on sale in US in 2015

If there was ever any doubt that Toyota loves hydrogen vehicles, just listen to some of what Bob Carter, senior vice president of automotive operations for Toyota Motor Sales, USA, said today at the Consumer Electronics Show (CES) in Las Vegas: "Fuel cell electric vehicles will be in our future sooner than many people believe, and in much greater numbers than anyone expected." "Hydrogen works beautifully with oxygen to create water and electricity and nothing more." "This [hydrogen] infrastructure thing is going to happen." "I believe what I'm going to tell you about today is going to change our world." Sounds like love is in the air. In all seriousness, Toyota is incredibly bullish on the future of hydrogen as a part of the automotive landscape, and is now gearing up for the 2015 launch of its hydrogen sedan. The concept version of the car was shown for the first time at the Tokyo Motor Show last fall and is making its North American debut at CES today, alongside the still-under-camo engineering prototype. The reasons for Toyota's hydrogen confidence? The debut vehicle is supposed to be a "reasonably priced" car that has a range of 300 miles and a refueling time of about five minutes. Carter highlighted the engineering work that Toyota has done over the past decades to get the fuel cell system downsized while upping power output to over 100 kW. He also said the vehicle will have carry enough energy to power a house for a week, so company engineers are working on an export power supply device. The H2 Toyota sedan will start sales in California (the only state in the US where there are currently any hydrogen stations) next year. The automaker is working with the University of California Irvine's Advanced Power and Energy Program (APEP) to figure out where to build the next series of public hydrogen fueling stations. Today there are ten, but the model Toyota is using "is based on the assumption that owners want to reach a refueling station within 6-minutes" and shows that 68 stations would be able to serve around 10,000 hydrogen vehicles.

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.
