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. Read more in the press release below. 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.

Economy-car buyers increasingly get the best deal on technology

One of the great things about technology is – with the exception of Apple products – consumers get more for their money every year. For example, the first 1GB USB drive I bought in 2005 cost me $30. Today you can get 10 for that price, delivered to your door thanks to Amazon. The same goes for car tech. Features such as navigation and Bluetooth started out on high-end vehicles before trickling down to entry-level cars. Same with driver assist features ranging from rearview cameras to forward collision warning with automatic emergency braking — so now it's not only rich people who are protected in car crashes. I've found that this democratization of tech has reached a point where amenities on low-cost cars can be as good — and sometimes even better — than those on vehicles costing tens of thousands of dollars more. While attending a media event for the launch of the all-new 2019 Toyota Corolla Hatchback, I was impressed by the car's cool styling and go-kart performance. Equally noteworthy is the amount of standard tech on the low-cost hot hatch. (Pricing will be announced later this month, but expect it to come in a bit higher that the current Corolla iM's roughly $19,000 base.) Even the base SE CVT trim of the 2019 Corolla Hatchback comes with an 8-inch touchscreen and Toyota's Entune 3.0 infotainment system. Among other features, Entune 3.0 provides Wi-Fi capability, Amazon Alexa connectivity, the Entune App Suite for integration of smartphone apps such as Pandora and Yelp and, for the first time in a Toyota, Apple CarPlay (but no Android Auto). The 2019 Corolla Hatchback is also the first North American vehicle to get the second-generation Toyota Safety Sense (TSS) suite of driver assists that's also standard on the base model. TSS 2.0 includes Toyota's Pre-Collision System (forward collision warning with automatic emergency braking) with new daytime and low-light pedestrian detection and daytime cyclist detection features, lane keeping and lane departure alert with steering assist, auto high beams, adaptive cruise control, and road sign detection. While the 2019 Corolla Hatchback sets a new benchmark in standard tech on a budget-mobile, competing cars aren't far behind. The 2018 Honda Fit LX, for example, includes forward collision warning with automatic emergency braking, lane departure warning and assist and adaptive cruise, while the automaker's Lane Departure Mitigation and Lane Watch camera system is added the two top trims.

Recharge Wrap-up: Minnesota first to require biodiesel, maglev in Israel, Toyota FCV in Aspen

A new Minnesota law that requires biodiesel blends goes into effect in just a few days, says KELO. Diesel drivers in Minnesota will be pumping soybeans into their tank beginning July 1. Every year, diesel will be sold as a B10 blend (ten percent biofuel) from April through August, and will scale back to a cold-hardy B5 blend from September through March. The biofuel largely comes from soybean crops grown within Minnesota, and the biodiesel industry pumps more than $900 million into the state economy every year. According to the National Biodiesel Board, using the B10 and B5 blends will reduce greenhouse gas emissions by 1,342,000,000 pounds every year. Minnesota is the first state to require diesel to be sold as a biofuel blend. In Japan, Isuzu Motors and Japanese biotech venture Euglena are teaming up to create biodiesel using algae, according to Bloomberg Businessweek. The goal is to create a new type of fuel that doesn't need to be mixed with light oil to be used in engines. "As long as we use light oil for diesel engines, emissions of carbon dioxide are inevitable," says Isuzu president Susumu Hosoi. Euglena has also been using algae to develop jet fuel with airline operator ANA Holdings. Isuzu and Euglena hope to have the new biodiesel developed by 2018. Aerial maglev transportation is coming to the campus of a defense contractor in Tel Aviv, Israel, Wired reports. The SkyTran personal rapid transit system uses small pods on an elevated magnetic track to move people from place to place. The pilot program will see SkyTran come to the corporate campus of Israel Aerospace Industries as soon as next year. The pods are hailed by phone, and carry passengers along the magnetic rail system at speeds of up to 44 miles per hour. The passive magnetic system levitates the pod attachment a centimeter above the rails, while a burst of electricity propels the pod forward. If the test at the campus goes well, SkyTran could spread to Tel Aviv at large, moving up to 12,000 people per track per hour with top speeds of 150 mph. The pre-production prototype of the Toyota FCV will make its North American debut at the 2014 Aspen Ideas Festival on Friday, June 27. The hydrogen car's finished exterior was revealed in Japan on Wednesday along with its nearly $70,000 price tag. It will go on sale in Japan by April of next year, and will come to Europe and California in the summer of 2015.
