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.

Recharge Wrap-up: Qualcomm invests in Chargemaster, gamers will appreciate these Toyota Prius C ads

Chargemaster has received an investment from Qualcomm for wireless charging in the UK. Of the 27,000 charging stations it has already installed, 10,000 are ready to be adapted for inductive charging, according to Chargemaster. Dr. Anthony Thomson of Qualcomm says that with this investment (of a currently undisclosed amount), "we are taking another step towards deployment of a convenient and easy to use WEVC network." The convenience of wireless charging not only makes life easier for current EV drivers, but could also help convince more people to make the switch to electric driving. Read more at EV Fleet World or at Hybrid Cars. Toyota has released Japanese ads for the Prius C using music from popular video games. The ads, which borrow scores from Dragon Quest III and Monster Hunter, also use the tagline "Fun to drive, again." While some may find the link between driving and role-playing video games tenuous, fans of green cars and gaming know the various feedback displays in cars like the Prius C can make eking out every last mpg possible feel like a game, with the car's Eco Score essentially the equivalent of a game's high score. Plus even if the reference is lost on a viewer, the ads do instill a sense of adventure. See and hear for yourself in the videos below, and read more at Kotaku. The electric vehicle charger (EVC) market is predicted to grow by significantly worldwide by 2020, according to a new report. It shows a predicted compound annual growth rate of 28.28 percent between 2013 and 2020. Level 2 charging station sales will expand from $0.2 billion in 2014 to $3.5 billion by 2020, while growing from $67 million in 2013 to about $947 million in 2020 in the US alone. For 2014, residential EVC sales currently make up 70 percent of those in the US, while sales between home and non-residential level 2 chargers is expected to be about equally divided by 2020.

Recharge Wrap-up: Toyota i-Road and COMS in France, Tesla tours Northeast, EV attitudes in UK

Toyota's i-ROAD and COMS teeny, tiny, city EVs are joining the Citelib carsharing fleet in Grenoble, France. The ultra-compact EVs, which will become available in October, are meant to supplement the Grenoble metropolitan area's existing public transit infrastructure, which includes trams, buses and trains. Toyota's i-ROAD and COMS will be connected to the transit systems IT infrastructure, allowing users to visualize their route on their smartphone or computer, and reserve and pay for their car before they get dropped off near the charging station (or the other way around). Then, the user finishes (or begins) their trip with one of the EVs. Surveys show that use of public transport is increasing in Europe, but most users still have to walk 15 minutes or so to reach their destination. Adding the i-ROAD and COMS carsharing service to their commute makes the trip into the city center quicker and more flexible, while keeping the air clean. See more below. Toyota is providing 70 vehicles to the Citelib program as part of a three-year test, while French energy company EDF is contributing 30 charging stations to the project. The i-ROAD is a three-wheeled EV that seats two people, and it features Active Lean technology for stability and comfort in the corners. Its footprint is about one-fourth that of a regular car. The four-wheeled COMS EV seats one, but also features a small storage compartment in the rear. The Tesla Model S is going on tour throughout the Northeastern US to give test drives to the public. Beginning July 4 in Montauk, NY, and ending August 30 in Vergennes, VT, people will get the chance to take a 15-minute spin in what many consider to be the best electric car available as part of Tesla's Fully Charged tour. If you live in New York, New Jersey, Massachusetts, Maine, Connecticut, New Hampshire or Vermont, the Model S may be coming to a town near you (check the schedule here) and you'll get the chance to drive the car with a product specialist in the passenger seat to answer your questions. You can even bring up to three guests in the back seat. So if you live in one of the states where Tesla can't sell cars or doesn't have a store, this is your chance to get to know the vehicle and decide if you want to buy one. Or you can just see what it feels like to silently go from 0-60 in 4.2 seconds (hint: it's pretty cool). A UK Survey shows five percent of people there are considering buying an electric vehicle.
