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

2020 Ram 1500 EcoDiesel Limited Drivers' Notes | Black gold

Ram didn’t have fuel economy numbers for us when we first drove the 1500 EcoDiesel, and because of that, a verdict could not be rendered. Today, thatÂ’s no longer the case. In maximum hypermiling 4x2 form, the EcoDiesel is rated at 22 mpg city, 32 mpg highway and 26 mpg combined. That puts it merely 1 mpg away from the Chevy Silverado Duramax, which achieves 33 mpg on the highway. In our testerÂ’s crew cab 4x4 configuration, it was rated at 24 mpg combined. The impressive efficiency can be attributed to the fully reworked 3.0-liter turbodiesel V6 under the hood. It makes 260 horsepower and 480 pound-feet of torque, with the full brunt of that torque being realized at a low 1,600 rpm. ItÂ’s a good thing, too, because the EcoDiesel redlines at 5,800 rpm. Towing maxes out at 12,560 pounds, and it has a payload rating of 2,040 pounds. ThereÂ’s a whole lot of truck to pull around, too. The crew cab backseat leaves enough space for even the tallest of riders to sprawl out, and the front seat is just as expansive and intimidating. As tested, our Ram 1500 was easily one of the most luxurious, expensive configurations one could possibly spec. It was done up in the highest Limited trim, which means every last premium material and feature is along for the ride. The base price was $58,660, but that doesnÂ’t mean Ram didnÂ’t find plenty of room for options. The most expensive of options happened to be the EcoDiesel engine itself, which comes in at $4,995. Yowza. Our truck also had the $3,995 Black Appearance Package, which adds an array of extras like 22-inch black wheels, a 19-speaker Harman Kardon audio system and black accents throughout the exterior. However, the 22-inch wheels were superseded by our truck's $795 Off-Road Group package that added 20-inch wheels with meatier tires, an electronic locking rear axle, multiple underbody skid plates and hill descent control. A $2,295 driver assistance package added adaptive cruise control, lane-keeping assist, a parking assistant, 360-degree camera and ventilated rear seats among other less notable features. Lesser charges like the $1,495 panoramic sunroof, $995 Multi-Function tailgate and $995 RamBox system all contributed to this truck's $75,610 final price.

Chrysler recalling hundreds of thousands of Jeep Grand Cherokee and Commander SUVs

The public might associated ignition switch recalls with General Motors - and with good cause - but that's not the only automaker calling its vehicles back in to fix that sort of issue.
Last month we reported that the National Highway Traffic Safety Administration was investigating an array of Chrysler Group vehicles for electrical-related safety issues. The administration and Chrysler subsequently issued a recall for 700,000 Dodge Journey crossovers, Dodge Grand Caravan minivans and Chrysler Town & Country minivans. But while the Jeeps that were also under investigation were not covered in that recall, they are being addressed in a separate one now.
Although Chrysler reports that it is only aware of a single accident stemming from this issue, it is "committing now to conduct a recall out of an abundance of caution." The recall affects the 2006-2007 Jeep Commander and 2005-2007 Jeep Grand Cherokee, of which it reports there are 792,300 on the road: 649,900 in the United States, 28,800 in Canada, 12,800 in Mexico and a further 100,800 outside of North America.
