Recharge Wrap-up: Toyota Prius airbag recall, Peugeot launches eU01s e-bike

Toyota is recalling 7,600 Prius vehicles for an airbag issue. Certain examples of the 2016 Prius could have malfunctioning inflators that could cause the passenger side airbags to deploy accidentally. There are no known injuries from the faulty airbags, but Toyota says, "This has been observed when the vehicle is parked and unoccupied for a period of time." Toyota also says this issue is unrelated to the massive recall of airbags supplied by Takata. The automaker will contact affected owners to arrange free repairs. Read more at Automotive News. Peugeot is adding another e-bike to its portfolio with the eU01s. What sets this electrically assisted bicycle apart from both regular bikes and other pedelecs is its ability to propel the bike to 28 mph under electric power. It comes with either a 400- or 500-Wh lithium-ion battery, providing 47 or 59 miles of range, respectively. It also offers an optional on-board computer with its 4.3-inch screen, through which riders can customize the electric assistance, get directions, receive sports coaching, and connect their smartphone. Earlier this year, Peugeot also launched its e-Kick scooter and folding eF01 e-bike. Read more at Green Car Congress. BYD is expanding its manufacturing facility in the US. In the second of three phases for the plant, BYD is adding onto its factory in Lancaster, California, where it currently builds electric buses. The Chinese company plans to triple the number of employees, up from the current 400, as it expands the facility by 40,000 square feet. BYD plans to build medium- and heavy-duty trucks at the plant, but declined to comment on whether it has plans to build light-duty vehicles there. Read more at Automotive News. The German states of Hesse and Baden-Wuerttemberg are suing Volkswagen over the Dieselgate scandal. The states are joining other investors seeking damages over losses incurred because of the automaker's emissions cheat device. Hesse Finance Minister Thomas Schaefer said the scandal cost the state about $4.4 million in stock losses, while Baden-Wuerttemberg likely lost closer to $450,000. Bavaria said earlier that it would sue Volkswagen on behalf of its pension fund for civil servants, which lost around $780,000. Read more from Automotive News Europe.

Toyota, Mazda drop Takata as Mitsubishi, Subaru weigh options

It's not a very good time to be Takata right now. Fresh on the heels of longtime partner Honda ditching them, Toyota and Mazda have both come out and said they will not use the company's airbag inflators if they continue to rely on ammonium nitrate. Bloomberg reports that Subaru and Mitsubishi are also contemplating a divorce. "The inflator using ammonium nitrate produced by Takata will not be adopted by Toyota," President Akio Toyoda said during a briefing today. "What's most important above anything else is the safety and peace of mind of customers." Mazda echoed that position, simply saying it "will not use Takata airbag inflators which contain ammonium nitrate in our new cars." When you lose three huge OEM accounts in as many days, it's certainly going to have a deleterious effect on your fortunes. In Takata's case, that's meant a staggering 39-percent drop in their share price over the last three days. Yesterday alone, the company saw a 6.2-percent fall, Bloomberg reports. As the business publication reports, though, Takata isn't going down without a fight. The company is "considering some plans to survive," including a fundraising plan that will see it potentially offer up additional shares for sale. Still, at least one analyst doesn't see whatever company survives staying involved in the airbag inflator business. "I really don't see how they're going to be able to survive as an inflator manufacturer," Valient Market Research founder Scott Upham told Bloomberg. "When your major clients publicly come out and say that they're not going to use your products anymore, it makes this very difficult to sustain your business."

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.
