Customers want wireless charging in next-gen Prius Plug-In; they might get it

Could 2016 be the year prospective Toyota Prius Plug-in Hybrid buyers are waiting for? Why, yes, says an unidentified Toyota spokesman. That's according to Plug-in Cars, which reports that a wireless plug-in vehicle charging system may be less than two years away for the Prius Plug-in. WiTricity has, for a few years, been developing its magnetic resonance wireless charging system for the model. This type of system allows for more distance leeway than other wireless setups when it comes to how close the car and its on-board receiver need to be to the floor-mounted system. That allows for smaller, lighter on-board receivers, which is key for any plug-in vehicle. Toyota spokeswoman Jana Hartline confirmed in an e-mail to AutoblogGreen that the company has conducted wireless charging tests in Japan "with hopes to bring that technology to market in the near future" but declined to provide more detail on the company's plans to offer wireless charging for plug-ins. Toyota's Satoshi Ogiso said last summer that the Prius Plug-in would eventually offer a wireless charging system in response to prospective customers' demand for it, though he wasn't specific on a time frame. Toyota started discussions with WiTricity regarding wireless charging system development more than three years ago and said late last year that it had reached a licensing agreement with the Boston-based company. WiTricity has also worked on developing wireless-charging systems that are compatible with Audi and Mitsubishi vehicles. WiTricity grew out of MIT back in 2007, back when we could barely imagine how it would work.

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.

Toyota Mirai might be the name of new fuel cell car; it means 'future'

Anybody remember the Ford Futura? It wasn't exactly a world-beater of a car, so we don't think the name Toyota's has apparently chosen for its first production fuel-cell vehicle is a tribute of sorts. Though one never knows. Maybe Toyota just likes 18-inch-tall EVs. The Japanese automaker has apparently settled on a nameplate for its fuel-cell model, and the name will be "Mirai," which means "future" in Japanese, Bloomberg News says, citing a person familiar with the process that it didn't identify. Bloomberg couldn't get anyone with Toyota to comment on record about the name – and neither could AutoblogGreen – but we do remember that Toyota has bandied this name about before, so we're not setting anything down in stone quite yet. Last month, Toyota said the new fuel cell car would debut in Japan next April and would be priced at about $69,000 before any sort of government incentives kicked in. The company hasn't revealed details about a US release date or pricing here, but indicated that US sales would start where there's already some semblance of a hydrogen-refueling infrastructure. That pretty much means California and nowhere else in the states. The fuel-cell model is said to have a full-tank range of about 435 miles and that the tank can be filled up in about three minutes, similar to a gas-powered vehicle. In other words, the future.
