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

Toyota asking NHTSA for fuel cell car safety exemption regarding electric shocks

Toyota is requesting an exemption from federal safety regulations that govern electric cars as it prepares to launch a small-scale hydrogen fuel-cell vehicle fleet.
The Japanese automaker is targeting Federal Motor Vehicle Safety Standard 305, which covers the packaging of high-voltage parts in electric cars. According to Uncle Sam, these systems need to be isolated so that passengers and first responders aren't electrocuted in the event of a crash. That seems pretty smart, but it's become a problem for Toyota's upcoming production fuel cell vehicle, as the mechanism that prevents electric shocks in low-speed crashes will apparently simply keep Toyota's car from even functioning.
Instead of the federally approved system, Bloomberg reports that Toyota plans to insulate the high-voltage wires and cables in the car, along with shielding electrical components like the fuel cells, electric motor and batteries with (presumably non-conductive) metal barriers.

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.
