Toyota RAV4 EV recalled for Tesla motor assembly software problem

As we noted this morning, Toyota is recalling 112,500 cars and SUVs to fix problems with electric power steering controls and electric vehicle software. The largest of two recalls announced yesterday cover about 110,000 2015 Camry midsize sedans and Highlander SUVs, as well as 2014 and 2015 RAV4 SUVs. There is a specific problem for those RAV4s that are also of the electric variety, which Toyota built with Tesla help from 2012 through 2014. This recall covers 2,500 RAV4 electric vehicles. Software in a motor assembly can make the vehicles shift into neutral on their own. Toyota says it knows of no crashes or injuries that resulted from the problem. For the non-EV-specific recalls, Toyota says a circuit board in the electric power steering may have been damaged at the factory. Power-assisted steering could fail, increasing the effort needed to steer and raising the risk of a crash. Dealers will inspect and replace power steering controls if needed.

Recharge Wrap-up: Mirai earns Toyota "Most Innovative" honor, Tesla cold-weather range

A Tesla driver has graphed the effect of cold weather on the driving range of his Model S. Rob at Teslarati kept track of the amount of miles driven and energy used and mapped that against temperature readings to find how the colder temperatures affect efficiency. The results were an average of 10 miles of range lost for every 10-degree drop in temperature. Also, he calculated that drivers will lose about 25 percent more range when the roads are slippery.

AEC produces composites for the aerospace industry, and having proven themselves in that field, they show promise for helping automakers make their cars lighter and more efficient without sacrificing structural integrity. "The agreement announced today is excellent news for our global automotive customers as we work to find further weight reductions in vehicles to meet future CO2 reductions," says Ricardo CEO Mark Garrett. With carbon composite prices expected to drop, Garrett believes this is an "attractive solution" for structural components. Read more at Ricardo's website. Toyota Motor Europe (TME) wants to recover all of its hybrid batteries for remanufacturing. TME currently recovers 91 percent of Toyota and Lexus batteries at the end of the vehicles' lives through dealerships, and is now working with independent end-of-life vehicle treatment operators to recover the rest. Beyond just being recycled, Toyota is looking into remanufacturing batteries for other vehicles or for stationary energy storage systems. Read more in the press release below. Fast Company Magazine has recognized Toyota as one of the 50 Most Innovative Companies for 2015 for its Mirai fuel cell sedan. "Toyota plans to do for fuel cells what its Prius did for hybrids: make them ubiquitous and top of mind for environmentally conscious consumers," says Fast Company. The article also notes that Toyota has also made its fuel cell patent public and invested in hydrogen fueling infrastructure. Toyota is ranked number 18 in the Most Innovative list, just below Tesla.

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.
