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.

Japanese automakers will seriously subsidize hydrogen fuel stations

Fresh off the announcement of the EPA-rated fuel economy and range figures for the Toyota Mirai, three of Japan's major automakers are throwing their weight behind hydrogen on the other side of the Pacific. Toyota, Nissan, and Honda are detailing their partnership in Japan to subsidize the creation of an expanded FCV refueling infrastructure there in the coming years. The plan could provide a much-needed boost for goals that are already looking to miss their targets. The partnership, which is called the Joint Hydrogen Infrastructure Support Project, is subsidizing a third of the annual operating expenses up to a maximum of 11 million yen ($90,000) for any hydrogen refueling station that applies and is accepted into the program. For now, the automakers plan to keep this running through around 2020. Toyota senior managing officer Kiyotaka Ise tells Bloomberg the whole thing over that time is expected to cost 5 billion to 6 billion yen ($40.5 million to $49 million). In addition to the money, the companies are trying to raise awareness about the alternative fuel to build popularity. Japan has been pushing extremely hard to build the FCV market there for quite some time by subsidizing both the models and building refueling stations for them. By the 2020 Olympics, the country's goal is to have 6,000 fuel cell vehicles on the roads and possibly even 100,000 of them by 2025. The cars to fulfill these lofty hopes are just gaining steam, though. For example, the Mirai is already experiencing high demand, and Honda is set to bring its new challenger in 2016. This announcement says Nissan is aiming a potential entry for 2017, as well. According to Bloomberg, the fuel cell industry in Japan is forecasted to balloon from 400 million yen (3.3 million) in the current fiscal year to 100 billion ($813 million) by 2025. Toyota, Nissan, and Honda Agree on Details of Joint Support for Hydrogen Infrastructure Development Toyota Motor Corporation, Nissan Motor Co., Ltd., and Honda Motor Co., Ltd. have agreed on key details regarding a new joint support project for the development of hydrogen station infrastructure in Japan. In addition to partially covering the operating costs of hydrogen stations, the three automakers have also agreed to help infrastructure companies deliver the best possible customer service and create a convenient, hassle-free refueling network for owners of fuel cell vehicles (FCVs).

VW targeting 10M sales in 2014

Volkswagen Group believes it can sell over 10 million vehicles in 2014, with hopes of overtaking Toyota as the world's largest automaker in the process. If VW can do it, it would meet that goal four years earlier than planned. Of course, Toyota isn't sitting still - it also hopes to top the 10 million-car threshold this year and has the advantage of already holding the top spot.
"With rising volume and new models, we will increasingly see positive earnings effects as well," said VW Group CEO Martin Winterkorn during its annual press conference, according to Automotive News. The company is spending huge amounts of money to propel it to the top, investing 84.2 billion euros ($117 billion) through 2018, and according to AN it plans to introduce over 100 new models worldwide among all of its brands by the end of next year.
The German automaker may get an extra boost as the European car industry shows signs of emerging from its yearlong stagnation and China continues to grow. In January, VW Group was up 8.5 percent in Europe and 15.5 percent in China, according to its own figures. However, the US has been slowing with Volkswagen brand sales down 19.04 percent in January and down 13.81 percent in February.
