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.

Toyota settles complaints with states Attorneys General for $29 million

Toyota announced today that it has reached a settlement with the Attorneys General of 29 states and one US territory that will resolve their complaints relating to recalls performed by the automaker from 2005-2010, including those related to sticky accelerators and malfunctioning floor mats that may have contributed to cases of unintended acceleration.
The settlement includes a payout of $29 million to be divided among the states and US territory, as well as a commitment from Toyota "to take steps to make vehicle information more easily accessible to consumers to help them operate their vehicles safely and make more informed choices." The settlement also has Toyota continuing its rapid-response service teams and quality field offices that were put in place shortly after the largest of the recalls from 2010, as well as a "range of customer care amenities for owners of vehicles subject to certain recalls," though the press release below isn't specific about what those amenities might be.
This settlement marks the second major step in the last few months that Toyota has taken to settle legal disputes surrounding the unintended acceleration recalls, the first being a $1.4 billion settlement to address economic loss suffered by owners of current and past Toyota vehicles that may have lost value on account of these recalls.

Toyota will roll out solid-state battery EVs globally in a couple of years

GANDHINAGAR, India — Japan's Toyota Motor will in a couple of years globally launch vehicles with solid-state batteries that charge faster and last longer, an executive said on Thursday at an investment summit in India. Solid-state batteries promise to dramatically improve the driving range of electric vehicles (EVs), a key element of a strategic pivot Toyota unveiled in June to make up ground lost to Tesla and Chinese rivals, such as BYD, in the EV race. Last year, Toyota and oil refiner Idemitsu Kosan said they would tie up to develop and mass produce all-solid-state batteries, which they aim to commercialize in 2027 and 2028, followed by full-scale mass production. "We will be rolling out our electric vehicles with solid state batteries in a couple of years from now," said Vikram Gulati, the India head of Toyota Kirloskar Motor. It "will be a vehicle which will be charging in 10 minutes, giving a range of 1,200 kms (750 miles) and life expectancy will be very good". Gulati was speaking at the Vibrant Gujarat Global Summit where one focus of the Indian government is attracting more investments to scale up EV manufacturing capacity in the world's third largest auto market. At the start of the summit on Wednesday, Japan's Suzuki Motor said its Indian subsidiary and Toyota partner Maruti Suzuki would export the group's first battery EV to Japan and Europe — marking the first time for Maruti to export to its parent company's home country. Electric models made up around 2% of India's car sales last year, but the government is targeting 30% by 2030 and India's road transport minister said at the summit he sees annual EV sales in India reaching 10 million vehicles by 2030. On Toyota's plans for solid-state batteries in India, Gulati said the carmaker had various sustainable technology options that would differ based on the country, market and customer preferences. "Right now, for India, flex fuel and ethanol can be a no-brainer right away," he added India's trade department has backed lowering taxes on hybrid vehicles to help the transition to cleaner energy sources, following demands by Japanese carmakers, Reuters has reported. Gulati said the Indian government should consider a carbon-based tax structure for cars, which would make it technologically agnostic and more equitable.  Green Lexus Suzuki Toyota Electric
