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

Move over Audi, now Chrysler has a beef with Tesla's claims

In the same week that Audi said "not so fast" to some claims from Tesla, Chrysler has responded to a new press release from the California-based EV-maker by saying "not exactly, Tesla." The statement, released through the company's blog, comes in response to Tesla claiming it was "the only American car company to have fully repaid the government." Chrysler notes that it, too, recently paid back Uncle Sam from its 2008 bailout. Similar to Audi's recent press release, which was eventually and mysteriously deleted from the German automaker's site, Chrysler is both right and wrong in its statement.
Tesla specifically said that it had paid back the Department of Energy loans that many automakers received - including Fisker and VPG Autos - while Chrysler's retort argues Tesla is "unmistakably incorrect" since it repaid the government in 2011 a full six years early. Technically, the statements from both automakers are correct, but Tesla's startup loan originated from the DoE, while Chrysler's loan came in bailout form from the Troubled Asset Relief Program (TARP). Further, as The Detroit News notes, Chrysler's loan still cost taxpayers well over a billion dollars after all was said and done - those negative assets tied to "old Chrysler" in the bankruptcy did not require repayment.

FCA seeks partner to keep building Dodge Dart, Chrysler 200

Mere weeks after FCA announced it was shutting down production of the Dodge Dart and Chrysler 200, new hope emerges to give the sedans a stay of execution. Speaking at the Geneva Motor Show last week, Sergio Marchionne said that the company was looking for a partner "who is better at it than we are and who has got capacity available" in order to continue building the models on its behalf. "There are discussions going on now," said Marchionne, according to Motor Trend. "I think we will find a solution. We continue to talk. It's both a technical solution and an economic one. We need to find a solution that works economically." Contracting vehicles to be manufactured offsite is more common practice among European automakers than it is with American ones. Chrysler's former patron Mercedes, for example, has the G-Class built for it by Magna Steyr in Austria, the A-Class by Valmet in Finland, and the R-Class by AM General in Indiana (even though it's no longer sold in the US). This arrangement would, on the surface at least, appear more similar to the deal that Toyota struck with Mazda to build the Scion iA, drawing on the contractor's expertise and capacity to build the small sedan on the client company's behalf. Only rather than basing a new model on one of the partner's existing ones, this deal would ostensibly continue building FCA models on FCA platforms using FCA components. We'll have to wait to find out with whom FCA strikes up the manufacturing deal, but we wouldn't be surprised to see Marchionne turn to a partner he already knows. The company is, after all, at the center of an intricate web of joint ventures and manufacturing contracts. The Fiat 124 Spider, for example, is built by Mazda. The Fiat Sedici that preceded the 500X was built by Suzuki. Models like the Dodge Stealth and Eagle Talon were built in Illinois at the Diamond-Star Motors joint venture before Mitsubishi took it over altogether. And Dodge continued selling the Mercedes-made Sprinter long after DaimlerChrysler split. The Ram ProMaster, though built by FCA in Mexico for the North American market, stems from a partnership in France with PSA Peugeot Citroen. And the ProMaster City is built in a joint-venture plant in Turkey, from which it's also sold by GM as an Opel in Europe and a Vauxhall in the UK. With all those deals coming and going, after all, what would one more add to the complexity?
