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

Ram/Jeep Ecodiesel engine has Maserati roots

The 3.0L turbodiesel V6 in the 2014 Ram 1500 EcoDiesel earned a slot on Ward's Automotive 2014 10 Best Engines for its power, fuel economy and refinement. In a piece looking at how Fiat subsidiary VM Motor developed the engine, Ward's also makes note of the fact that the same lump goes in diesel versions of the Maserati Quattroporte and Ghibli. They're tuned a bit differently, naturally, with the QP putting out 275 horsepower and 442 pound-feet of torque, the smaller, lighter Ghibli making do with the same number of horses but a lower torque output of 420 lb-ft.
The 240 horsepower and 420 pound-feet put out by the oil-burning six-cylinder in the Ram was tamed with a host of advances, but it appears that Ram hasn't tamed demand: the initial allocation of 8,000 engines was spoken for within three days of the truck going on sale. Head over to Ward's to read the story of how Ram worked out the equation light-duty-pickup + diesel = success.

Chrysler recalling 280k Dodge Ram 1500 pickups over axle seizures

Following a June investigation by the National Highway Traffic Safety Administration, Fiat Chrysler Automobiles will be recalling 280,000 Dodge Ram pickups from model year 2005. The issue, NHTSA told The Detroit News, centered on a loose pinion nut, which could cause the rear axle to seize and, potentially, the driveshaft to detach. The affected vehicles were built between January of 2004 and August of 2005, while of the 280,000 trucks, only 257,000 were sold in the US market. According to The News, the recall will begin on February 13, and will see owners report to dealerships to have "a retention feature" added to the pinion nut.
