Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.

Dutch Toyota dealer has plans for old Prius batteries as solar backup

A Toyota dealer in the Netherlands is looking to the sky for power. The Louwman Hague Toyota dealership has put almost 1,000 solar panels on the roof, and there might be some Prius hybrid batteries involved. Our Dutch isn't as good as it could be and our questions to Toyota in the US haven't turned up any definitive answers, but there is some mention that these solar panels are will someday be feeding power into a bank of Toyota hybrid batteries. The 1,000 panels make up 1,600 square meters, about the size of 4.5 IMAX movie screens, and is the largest in the area. They generate around a quarter of a megawatt of energy [as our readers point out, this is what the translation says, but it doesn't make sense, so we think it might mean a quarter MW of power a day], which is enough to power 80 homes. The excess electricity will go into the battery packs that have (possibly) already been used in a Prius or another of the company's hybrid. There are many examples of automotive batteries being tested as stationary back-up power sources, and maybe this Dutch solution can be used as a guide when Toyota sets up its new US headquarters in sunny Texas.

Toyota passes BMW as most valuable car brand

An annual market study of the strongest brands across various industries has seen Toyota leapfrog BMW as the world's most valuable automotive brand. Toyota's 2013 brand value rose to $24.5 billion, up 12 percent versus 2012 numbers according to market research company Millward Brown's BrandZ Top 100 Most Valuable Global Brands list. BMW's value fell slightly; down by 2 percent to a total of $24 billion.
Mercedes-Benz finished in third place in the automotive category, up 11 percent from 2012 for a valuation of $18 billion. Honda ($12.4 billion, down 2 percent) and Nissan ($10.2 billion, up 3 percent) rounded out the top five for the category. Volkswagen was the only other auto brand that finished in the top 100 overall, in 100th place. Audi made the greatest percentage gain over 2012, up 18 percent to $5.5 billion, but finished outside of the top 100.
Technology companies dominated the overall list, with Apple, Google and IBM ranking one through three. Couture brand Prada was 2013's biggest gainer, rising by 63 percent over 2012.
