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

Chrysler recalling 382k Ram HD diesel pickups, 184k SUVs

Between GM's ignition switches and Takata's airbags, it's been a big year for recalls, but they keep rolling in. The latest comes from Chrysler, which has announced a pair of recalls for certain heavy-duty pickups and SUVs.
The first issue revolves around the 6.7-liter Cummins diesel engine available in the 2010-2014 Ram HD trucks, including 2500 and 3500 series pickups as well as 4500 and 5500 series chassis cabs. In the affected units, "a terminal connector near the fuel heater may be subject to friction-induced corrosion," according to the first of the two announcements from Chrysler below.
The problem could result in overheating and fuel leakage. Chrysler launched its investigation following cases of overheating, none of which actually started a fire, much less an injury or accident. As a precautionary measure, however, Chrysler is instructing service technicians to replace the terminals on an estimated 381,876 Ram units around the world - the vast majority of those (314,704) registered in the US, another 59,432 in Canada, 1,803 in Mexico and 5,937 abroad.

More details on the Hellcat-powered Ram Rebel TRX

We got our last big scoop on the coming Ram Rebel TRX last summer, when Jordan Denhoed caught a pack of prototypes testing in Michigan's Silver Lake Sand Dunes. We'd heard then that as opposed to the TRX concept, the production truck would unlock the full 707 horsepower from its 6.2-liter Hellcat V8, and use a traditional shift lever to work the gears of a 10-speed automatic. Now Mopar Insiders and Allpar have another batch of details that both sides said were gleaned from insiders with knowledge of the product. The looks, which will hew closely to the concept, have apparently already been teased. The Dodge and Ram corners of FCA like to foreshadow future offerings in their press photos and flyers, Ram doing so again on a graphic that advertised the FCA 2020 Drive for Design contest, pictured. We're told to expect the same twin-vented hood and flared arches front and back, as well as a new take on the current Ram Rebel grille that frames headlights from the Laramie Black trim. The side-exit exhaust would be cool, but we doubt it makes production. That extra width necessitates amber marker lights. The Ford F-150 Raptor, which uses the same lights for the same reason, places its markers along the top edge of the grille just below the grille surround. Mopar Insiders says the Rebel TRX's amber markers will lurk inside the large hood scoop. The Hellcat will get plenty of air from additional vents astride the headlights, and vent its heat through extractor vents just ahead of the windshield and ahead of the front doors. In lieu of any Hellcat badging save for on the supercharger, script on the hood in the same font as the Rebel TRX concept will read, "6.2L Supercharged." In back, yet more vents mimic those in the front fascia, this time placed next to the taillights. There will be an LED CHMSL, and larger diameter exhaust tips poking out of the bumper. Inside, Allpar says Ram plans to follow the Dodge SRT template by loading up the interior; the question is whether there will be a base model, or if it's only SRT plus options. The luxury angle means the 12-inch Uconnect infotainment system will be standard, with off-road-specific screens among the Performance Pages. Allpar confirms the conventional shifter, and Mopar Insiders says the lever will be joined by aluminum shift paddles borrowed from the Alfa Romeo Stelvio Quadrifoglio. The paddles will be longer than those in the Italian crossover, and mounted on the steering wheel.
