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

New Viper 'is a possibility,' Sergio Marchionne says

It was thought the door to the future for the Dodge Viper had closed last year, but Fiat Chrysler CEO Sergio Marchionne reopened it during his press conference at the 2016 Detroit Auto Show. Marchionne said the current Viper is the only FCA product to use the ZD platform, which "doesn't make sense to me." Yet, "given the architectural development within the brand, there is a possibility that a new version of the Viper may surface." Automobile reports that the company uses a versatile, rear- and all-wheel drive Giorgio platform for Alfa Romeo and Dodge. It will support the Alfa Romeo Giulia (Alfa Romeo's larger BMW 5 Series competitor), the next-generation Dodge Challenger, Charger, and rumored Barracuda, and it could support a new generation of Viper. We're probably talking about a different kind of Viper, though, with Automobile saying, "the current car's truck-based V-10 no doubt would be scrapped along with its platform." A Viper without a V10 doesn't seem like a Viper to us, but we'll wait to see what happens. In the midst of contract negotiations for a new labor agreement between FCA and the United Auto Workers last year, it emerged that the Conner Avenue Assembly plant that builds the Viper hadn't been given any new product after the end of Viper build-out in 2017. That led most to reason that the current Viper would be the end of the 25-year run of America's hairiest sports car. How long we'll be waiting is unknown. Marchionne had no timetable and admitted that a future Viper might not appear on the heels of the current one. With a renewed commitment to being debt-free by 2018, FCA is likely more focused on getting Alfa Romeo running properly and cranking out the volume variants for the Giorgio platform first.

Chrysler Recalling 870,000 SUVs For Brake Defect

Chrysler is recalling nearly 870,000 SUVs because corrosion may make the vehicles' brakes harder to use. Jeep Grand Cherokee and Dodge Durango SUVs from the 2011 through 2014 model years are involved. Chrysler says crimp joints in the brake boosters can corrode if they're exposed to water. If the water freezes, the boosters won't aid braking as they usually do. Chrysler began investigating after some customers said their brakes felt too firm when pressed down. The company knows of one accident, but no injuries, due to the defect. Dealers will install a shield to protect the boosters for free and replace boosters that aren't working properly. Chrysler has since changed the design to make the boosters more corrosion resistant. Chrysler will notify owners of the recall, which involves 867,795 vehicles.
