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.

Hyundai adds tech to Blue Link, offers it free for 3 years

Hyundai has not only thrown more technology at its 2018 lineup, the tech will be less expensive. At the New York Auto Show, the South Korean automaker announced that Blue Link remote services will be free for three years on the 2017 Ioniq and on all 2018 models, starting with the Sonata, Elantra GT, and Santa Fe Sport. The remote services include all three packages currently offered as options with a Blue Link subscription: Connected Care, Remote, and Guidance. Among the included features are automatic collision notification, a monthly vehicle health report, remote lock and unlock, stolen vehicle recovery assistance, and remote start with climate control. That last function gets an update for 2018 that allows control of the rear defroster and heated side mirrors on the coming Sonata and Elantra GT. The whole shebang tallies 10 features in the Connected Care Package, 12 features in the Remote Package, and 3 features in the Guidance Package. But wait, there's more: the SD-card-based navigation maps get free downloads for three years. Blue Link subscribers can already access remote functions with a smartphone and a smartwatch. For 2018, Amazon Alexa (via the Tap, Echo, and Echo Dot) and Google Assistant (via the Google Home speaker) become control devices. You can tell either gadget to start your car and set the climate control, to send an address to the navigation system, or start and stop the charging of an Ioniq. Right now, if a new buyer subscribes to Blue Link, he gets three free months of the Remote and Guidance packages, and a free year of the Connected Care Package. After the trial, each package costs $99 per year. By offering the packages free for three years, Hyundai dangles a savings of nearly $750 in front of those who can wait for the new models. Be sure to read this accompanying post about the Sonata's design. Related Video:

Renault, Nissan and Hyundai face shutdowns in India over workers' COVID fears

CHENNAI, India — Automakers Renault, its alliance partner Nissan and Hyundai face temporary factory closures in India due to growing unrest among workers concerned about rising COVID-19 infections. Workers at Renault-Nissan's car plant in the southern state of Tamil Nadu will go on strike on Wednesday because their COVID-related safety demands have not been met, a union representing the workers told the company in a letter on Monday. Hyundai said it would suspend operations at its plant, also in Tamil Nadu, for five days starting Tuesday, after several workers staged a brief, sit-in protest on Monday amid rising cases in the state. "The management agreed to close the plant after workers expressed concerns over safety after two employees succumbed to COVID," E. Muthukumar, president of the Hyundai Motor India Employees Union, told Reuters. The unrest highlights the challenges companies face in India amid a huge wave of COVID-19 infections, an overwhelmed health system and a shortage of vaccines which is making employees more fearful. Tamil Nadu is one of the worst hit states with more than 30,000 cases a day last week. The state, an auto hub known as India's Detroit, has imposed a lockdown until May 31 but allowed some factories, including auto plants, to continue operating. The strike threat at the Renault-Nissan plant came ahead of a court hearing on Monday over allegations from workers that social distancing norms were being flouted and factory health policies did not sufficiently address the risk to lives. Renault-Nissan has said it is following COVID-19 safety protocols. At the hearing, a lawyer for the workers argued that while the company had reduced the number of shifts, production numbers had not been cut and the headcount remained the same leading to crowding on the factory floor. The company told the court it had reduced the workforce to around 5,000 from 8,000. It also said it had vaccinated employees over 45 and was willing to inoculate those under 45 if vaccines were made available. The two-judge bench presiding over the case said that while the health of workers is paramount, if industries go down there will be no place for them to work. They also said the company must not take advantage of the exemption granted by the state and should reduce production to meet only necessary export orders. "The production should have fallen ... You also have to assuage the feeling of the workers," said the court, which will next hear the case on May 31.
