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

Dodge explains why it will build the Durango SRT Hellcat for only six months

Dodge will manufacture the 710-horsepower, Hellcat-powered Durango SRT only for approximately six months. The company explained that, while it won't stop production after building a pre-determined number of SUVs, it won't be able to extend the model's life cycle due to several manufacturing- and government-related hurdles. "The Durango SRT Hellcat is not limited, it's not serialized like what we did with the Challenger SRT Demon, but we're only building it for six months. With all of the changes we made in the plant to come back up to production post-COVID-19, with the sequencing and spacing in the plant, it's changed the numbers we can build," explained Tim Kuniskis, the head of Dodge, in an interview with enthusiast website Muscle Cars & Trucks. He added no one on his team knows precisely how many SUVs the Jefferson North factory on the outskirts of Detroit will put a Hellcat engine into. It largely depends on customer demand. Asked to provide an estimate, Kuniskis revealed he expects "less than 2,000" units will be made. They will all be 2021 models. In theory, Dodge could at least double that number by bringing the Durango SRT Hellcat back for the 2022 model year. It's not that simple in application, however, because the company won't be able to drop a supercharged, 6.2-liter V8 in its biggest SUV after 2021 without leaning on the wrong side of looming emissions regulations. "When we switch to the 2022 model year, there are new evaporative emission requirements that come in that the Hellcat engine does not meet in that platform," Kuniskis said. He also noted the Jefferson North factory will be busy retooling for production of the next-generation 2021 Jeep Grand Cherokee tentatively due out in 2020. Still speaking to Muscle Car & Trucks, Kuniskis clarified that the Hellcat-powered variants of the Charger and the Challenger will stick around in the foreseeable future; making them compliant with the upcoming emissions regulations is easier. And, he stressed the standard version of the Durango will carry on "completely interrupted." In other words: Act fast if you want a Durango SRT Hellcat. Dodge will begin taking orders in the fall of 2020, and production is scheduled to start in early 2021, with deliveries following shortly after. Pricing information hasn't been announced yet, but we expect its base price will be pegged in the vicinity of $90,000. Related Video:    

FCA recalls 210,000 new Jeeps and Dodges due to a brake issue

FCA is recalling some 210,000 vehicles in the U.S. and elsewhere over a possible braking issue. On this occasion, the recall is made less complicated by the fact that about one-third of the affected vehicles are so new, they still reside on dealer lots, making them easy to tally up and put right. The recall concerns 2018 Dodge Journeys, 2019 Jeep Cherokees and 2018-2019 Dodge Grand Caravans and 2018-2019 Jeep Compasses. Most were built in spring 2018, and the recall is related to a brake system component that failed to meet FCA specifications. Further information available on the NHTSA website details the issue, saying that insufficiently coated rear brake caliper pistons may cause gas pockets to form in the brake fluid of very new vehicles. This in turn can reduce rear brake performance — bubbles in brake lines are not desirable. FCA underlines that the brakes still function, but stopping distance can be affected. As a remedy, the brake systems are inspected and re-bled. The recall is slated to begin on Sept. 28. In addition to 154,337 vehicles in the United States, the recall concerns 19,066 units in Canada, some 900 in Mexico and some 35,500 vehicles on other markets.
