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

Detroit's new emergency city manager worked on Chrysler bankruptcy [w/video]

Kevyn Orr, the new emergency city manager of Detroit, has a history with one of Michigan's most famous residents: Chrysler. Governor Rick Snyder (at right) appointed Orr to the position yesterday with the belief that Detroit needs outside assistance to right the city's mounting financial woes. Orr (at left), a partner with the Jones Day law firm, will begin work on March 25 and receive $275,000 a year for his work. While state officials believe the new city manager will be able to complete his duties in 18 months, the contract is technically open-ended.
The 54-year-old attorney helped steer Chrysler through its 2009 bankruptcy, earning $700 per hour for his efforts. He was also instrumental in convincing the courts to allow Chrysler to shutter 789 dealerships in a single month. Orr says he's aware that his efforts won't have made him any friends in Southern Michigan.

Marchionne emailed Barra about merger between FCA and GM

Sergio Marchionne is adamant that global automakers will have to merge to remain profitable in the near future, and he'll tell that to anyone who's listening. Mary Barra, however, is not interested. According to The New York Times, the Fiat-Chrysler chief proposed a merger with General Motors via email to his counterpart back in March. Marchionne proposed meeting to discuss the matter, but Barra and her team reportedly rejected even entertaining the idea. This of course is not the first time Marchionne has raised the idea of a merger. He masterminded the marriage between Fiat and Chrysler, and reports have since suggested further mergers with Volkswagen, Peugeot, Ford, and others – including GM's own Opel unit. Some have taken his calls for consolidation as a weakness, but Marchionne insists that his empire is in good health – and that it's the industry as a whole which is in an untenable position. According to his view, automakers around the world need to align themselves into larger groups in order to reduce redundancy in investment, development and infrastructure – the duplication of which he terms as wasteful. "It's fundamentally immoral to allow for that waste to continue unchecked," said Marchionne to the Times. "I think it is absolutely clear that the amount of capital waste that's going on in this industry is something that certainly requires remedy," he said in a conference call with industry analysts late last month following the rejected GM approach. "A remedy in our view is through consolidation." News Source: The New York TimesImage Credit: Paul Sancya/AP Chrysler Fiat GM Sergio Marchionne merger fiat chrysler automobiles
