Recharge Wrap-up: Tow-charging a Tesla, Hyundai Tucson Fuel Cell taxis in Paris

Watch a Tesla charge another Tesla by towing it. Bjorn Nyland has found yet another way to explore what Teslas can do, this time by towing a Model S behind a Model X to recharge the sedan's battery. While it's not the most efficient method of charging, it's definitely one way you could help out a stranded electric motorist in a time of desperation. The single-motor S was couldn't quite hit its regen capacity of 60 kW because of the towing speed. Nyland suggests a dual-motor Tesla in tow might be able to capture more energy. Check out the video above, and read more at Teslarati. Paris-based taxi startup STEP (Societe du Taxi Electrique Parisien) will use 60 Hyundai Tucson Fuel Cells in its fleet. These will replace internal combustion taxis on Paris roads. Hyundai says that its Tucson Fuel Cell taxi fleet presence in Paris will increase from five vehicles to up to several hundred in coming years. Read more from Hyundai. Montreal is installing 50 new EV chargers, with a goal of 1,000 by 2020. The new chargers are in addition to 50 built downtown in August. "Our administration has bet on the electrification of transportation, with a view to being the first electric metropolis in North America," says Montreal Mayor Denis Coderre. The 50 new stations are spread out throughout seven boroughs of the city. Read more at Green Car Congress, or from the City of Montreal (in French). Denver will add 200 electric vehicles to its city fleet by 2020. The city plans to save $800,000 over the next decade due to the switch, as it starts to replace aging vehicles with electric ones starting in 2018. "Both financially and from the environmental perspective, it puts the city in a leadership position," says Denver Energy and Transportation Administrator Tyler Svitak. The city currently employs three EVs in its fleet. Read more at Hybrid Cars, or from The Denver Post.

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.

More than a half-million Hyundai, Kia compacts recalled for brake light problem

Hyundai and Kia will recall more than a half-million compact cars in the U.S. starting next year because of a brake-light problem. The recall covers more than 390,000 Hyundai Elantras from the 2013 and 2014 model years, and more than 134,000 Kia Forte cars from 2012 through 2014. The Associated Press, citing documents the companies filed with the federal government, reports that a polymer stopper pad between the brake pedal arm and the light switch can deteriorate and keep the brake lights on when the brakes aren't actually engaged. The problem also means a driver can shift out of park without stepping on the brake pedal. Neither automaker reported any crashes or injuries stemming from the issue. Dealers will replace the stopped pads starting Jan. 30 for Kia and Feb. 8 for Hyundai.Related Video:
