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.

2017 Hyundai Santa Fe and Sport reveal facelifts in Chicago

Hyundai needs crossovers. With the national average cost of gas at just $1.71 as of this writing, (short-sighted) consumers are charging back to dealers demanding new high riders. That's bad news for car-heavy manufacturers like Hyundai, and good news for brands that have embraced CUVs, like Subaru. Consider this: Hyundai sold 181,725 crossovers from its roughly 800 dealers in 2015. In that same period, the Subaru Forester alone racked up 175,192 sales, and that's with a dealership network 25 percent smaller than Hyundai's. At the 2016 Chicago Auto Show, Hyundai is showing off updated versions of its two-tier Santa Fe range. There's a new, more pronounced and rectangular grille; sharper, less organic headlights, and LED running lamps in front. But there are also a bunch of new gizmos and gadgets that Hyundai expects to elevate the Santa Fe's safety rating. A backup camera is now standard and you can now snag adaptive cruise control with a stop-start mode. There's also a raft of new safety features, including lane departure warning, automatic high beam assist, and auto emergency braking with pedestrian detection. It's partially because of that last item that Hyundai thinks the new Santa Fe will score an IIHS Top Safety Pick+ rating. The company hasn't explained what changes will allow it to improve on 2016's Moderate rating in the small-overlap test, though. But if Hyundai is correct, it'd be a serious coup – the Santa Fe hasn't been honored by the IIHS since its redesign for model year 2013. It'd also put the Santa Fe in a rarefied class of ultra-safe mid-size CUVs. Only the Honda Pilot and Nissan Murano have scored TSP+ ratings. Prices increase by $400 on naturally aspirated models and $450 for the top-of-the-line turbocharged trims. The new Santa Fe is arriving at dealers now.

The improvements span everything from fresh exterior design and LED lighting signatures to additional infotainment, convenience and safety technologies and new Drive Mode selection with Sport, Eco and Normal settings.

Hyundai calling in 65k Sonatas over ABS warning light

A problem with the ABS warning light has prompted Hyundai to issue a recall for nearly 65,000 examples of the Sonata sedan. The issue seeks to rectify an issue that would prevent a warning light in the dash from alerting the driver of a malfunction with the anti-lock brakes. The recall campaign specifically affects 2015-16 Sonatas manufactured between May 28, 2014, and August 21, 2015. Hyundai estimates that 64,744 such examples are to be found in the United States. If the warning light doesn't illuminate, the driver may not be aware that there's a problem with the ABS. And, according to the statement below from the National Highway Traffic Safety Administration, that could increase the likelihood of a crash. To fix the issue, Hyundai will notify owners to bring their Sonatas in to their local dealership to have the software in the control unit updated. The recall is scheduled to commence on December 11. Related Video: RECALL Subject : ABS Warning Lamp May Not Illuminate/FMVSS 135 Report Receipt Date: OCT 20, 2015 NHTSA Campaign Number: 15V678000 Component(s): ELECTRICAL SYSTEM Potential Number of Units Affected: 64,744 Manufacturer: Hyundai Motor America SUMMARY: Hyundai Motor America (Hyundai) is recalling certain model year 2015-2016 Sonata vehicles manufactured May 28, 2014, to August 21, 2015. The affected vehicles are equipped with an Antilock Braking System (ABS) warning light intended to warn the driver if there is an ABS malfunction. In the event of an ABS malfunction, the Brake System warning light will illuminate, but the ABS warning light will not illuminate. Since the vehicles have ABS malfunction lights that do not illuminate, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 135, "Light Vehicle Brake Systems." CONSEQUENCE: If the driver is alerted there is a brake system malfunction, but not specifically with the ABS system, the driver may operate the vehicle unaware that the vehicle's brakes may lock up during hard braking, increasing the risk of a crash. REMEDY: Hyundai will notify owners, and dealers will update the ABS control unit software, free of charge. The recall is expected to begin December 11, 2015. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 134. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
