Stellantis aims to eliminate separate inverter, charger to improve EV efficiency

Stellantis has announced that, in collaboration with French battery company Saft and French National Center for Scientific Research, has made significant progress in eliminating two major components of an electric vehicle powertrain: the on-board charger and the power inverter for the motor. The company claims that doing this will allow for better space use in vehicles, as well as improvements in efficiency, cost and reliability of components. As a quick primer, also explained in the below video, the on-board charger and power inverter are sort of translators to get the right current to different parts of the electric powertrain. The on-board charger takes AC power from the grid and converts it to DC to charge the batteries. Then when power goes from the batteries to the electric motor, the power inverter converts that DC power back to AC. These components aren't exactly small. Frequently you'll find them packaged somewhere under the hood. What Stellantis and its cohorts have developed, and have been using on a test vehicle since last summer, are small power inverter boards that can be mounted very closely to the battery packs. They can handle both conversion needs, for charging and discharging, instead of needing two separate devices. The most obvious perk to this is that you can do away with those traditional components and free up more space, either for making smaller vehicles without losing interior volume, or adding space to a vehicle that wouldn't have had it otherwise. There's the additional benefit of reduced weight, something that EVs struggle with. Stellantis also claims improvements in efficiency, reliability, and cost, however, it didn't go into detail as to how this setup would do that exactly. We'll try to get in touch with representatives from Stellantis in order to get more information. We're still a ways out from seeing this technology in production Stellantis vehicles. The company said it aims to apply it to vehicles by the end of the decade. Saft is also looking at using it on stationary battery systems as well. So maybe we'll see it on a 2029 Ram 1500 REV, but for now, we'll be living with traditional chargers and inverters. Related Video: Green Alfa Romeo Chrysler Dodge Fiat RAM Technology Electric

Undersized grille was #1 complaint of 2011-2014 Chrysler 300 owners

Not only did the 2005-2011 Chrysler 300 have a big ol' grille, it jutted ahead of the car. The grille was the metaphorical figurehead for the USS 300, and it did its job, making the sedan the Central Casting submission for "in-your-face styling" that rolled down the street winning the game of "Made You Look." The one-billion-dollar redesign for 2011 (pictured above) aimed for more upscale and less aggression - "a more grown-up look" - so the grille shrunk. And Chrysler 300 buyers hated that. So said Chrysler brand president Al Gardner to Edmunds, relating that the smaller grille was "the No. 1 issue" on the list of customer complaints about the model years from 2011 to 2014. It doesn't appear to have been much loved in-house, either, with Ralph Gilles having said of it, "Our previous generation of leaders didn't understand the car very well, and kind of forced this front end on us." That's why the grille on the 2015 model (pictured in 300S trim, inset) was aggrandized by 33 percent, although it's still not as large as on the first generation, and the more fluid design of the current car doesn't let it stand out as before. Gardner went on to say that designers "spent more time on the front end than on anything else," in search of, as Gilles put it, "the attitude it deserves." We'll soon find out if that increases the number of buyers it deserves as well.

Investors want answers about Marchionne’s final days

The mystery of Sergio Marchionne's surprise death last week continues, with investors now questioning the timeliness of disclosures by the company and family. Bloomberg reports that Italy's market regulator is making a routine check into how Fiat Chrysler handled communications regarding his illness. Fiat Chrysler's stock is down 12 percent in both Italy and on the New York Stock Exchange since the announcement of Marchionne's death. University Hospital Zurich last week issued a statement saying that Marchionne, who died July 25 while recovering from an unspecified should surgery, had been treated for more than a year for a serious illness that it didn't define. Marchionne's family told Reuters the companies hadn't been aware of his health conditions. The Italian business website Lettera 43 reported July 5, and FCA later confirmed, that Marchionne had undergone shoulder surgery in a Swiss hospital. But the company later denied a July 20 report by the website that Fiat Chairman John Elkann planned to meet with company leaders to divide Marchionne's responsibilities. Yet the FCA board indeed met on July 21 and chose Mike Manley, who had formerly overseen the Jeep and Ram brands, to succeed Marchionne as CEO. The company on July 25 published a brief statement acknowledging the former CEO's death. "Unfortunately, what we feared has come to pass. Sergio Marchionne, man and friend, is gone," Elkann said in the statement. Marchionne told no one outside his inner circle — reportedly not even Elkann — that he was seriously ill. His partner, Manuela Battezzato, who works in Fiat's press department, told Bloomberg that Marchionne's family didn't tell the company about his health condition. The famously hard-working CEO, who had quit smoking about a year ago, had also reportedly stopped responding to messages and calls from some advisors since the end of June. People close to him told Bloomberg that Marchionne died from complications following the shoulder surgery, including two cardiac arrests.
