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

2017 Ram 2500 Laramie 4x4 | Drivers' Notes

The Ram 2500 is a heavy-duty truck that sits square in the middle of Ram's truck hierarchy. Ram considers this the fourth-generation truck, with the first model debuting in 1981. The current truck first hit the streets back in 2009, with a number of updates and facelifts keeping things fresh since then. Despite its age, it still competes strongly with the Chevrolet Silverado 2500 and the Ford F-250 Super Duty. While Ram heavy duty trucks may be known for packing wonderful Cummins inline-six diesel engines, this particular model has a 6.4-liter Hemi V8 under the hood. The Laramie trim sits dead in the middle of the Ram lineup, just below the much-beloved Power Wagon. While it may not pack all the off-road capabilities of the Power Wagon, it has a few more comfort and convenience features that make it better to live with day-to-day. Senior Editor, Green, John Beltz Snyder: The first thing that struck me besides the towering ride height of the Ram 2500 Laramie was the firmness of the ride. Despite bouncing around quite a bit on our uneven city road surfaces, I kind of enjoyed the joyful feeling of the stiff suspension. I could see myself growing tired of it, though, after a long day of driving. Still, this truck was pretty fun Í— and surprisingly easy Í— to drive in traffic, which is not something I usually say or feel about pickups. The brake effort when coming up on highway jams was the only thing that really shook my confidence in the Ram. It's a beefy machine, too. It garners attention and a wide berth on the road. My 2-year-old son was instantly impressed with it, of course (though a little sad he couldn't fit in the center console storage bin like he could in the Ford F-150). A friend of mine who'd never before struck me as the pickup type ­(though now that I think about it ...) saw photos I posted on Twitter and commented, "I'd drive that truck, dang." Then, later in our conversation, she summed up in just a few characters the conflicted feelings that this particular pickup had been stirring up in me all night: This content is hosted by a third party.

It provided me with guilty pleasure, instead of just guilt. Editor-in-Chief Greg Migliore: What's better than a Ram 1500? How about a 2500. Call it the Power Wagon syndrome: Suddenly I feel like I need a 2500 to do anything.

China own a Detroit automaker? Would the U.S. let that happen?

The news that several Chinese automakers want to buy Fiat Chrysler Automobiles, and that one has even made an offer, elicits some mixed feelings. On one hand, as some have pointed out, it could be a win-win both for China and for FCA's American workers, ensuring the company's survival and opening new markets. On the other hand, this is China, whose trade relationship with the U.S. is the source of considerable scrutiny from the Trump administration — and whose not-a-friend, not-an-enemy status is particularly difficult to gauge right now during heightened tensions with its client state North Korea. So would such a deal pass regulatory muster? One reason that springs to mind for blocking any sale has to do with national security. Chrysler's role as a military supplier dates back to Dodge trucks used by Gen. Blackjack Pershing to chase Pancho Villa in Mexico, and shortly thereafter by American forces in World War I. The Detroit Three automakers were, of course, mainstays of the Arsenal of Democracy of World War II. Even before U.S. entry into the war in December 1941, America's industrial machinery went into overdrive, and Chrysler was one of the biggest cogs. It engineered and built the M3, Sherman and Pershing tanks and trucks for Gen. George Patton's Redball Express. It helped develop a radar-guided antiaircraft gun that knocked German bombers and V1 rockets out of the sky — on one day, shooting down 97 of 101 V1s headed for London. On D-Day, the radar system helped thwart Luftwaffe counterattacks on the beaches of Normandy, and it later helped Allied forces break out at the Battle of the Bulge. Chrysler redesigned the Wright Cyclone engines used by the Boeing B-29 Superfortress, the plane that firebombed Tokyo and dropped the atomic bombs that ended the war. Chrysler even played a secret role refining uranium in Oak Ridge, Tenn., that was used in the Hiroshima bomb and in the ensuing Cold War arms race. It worked on military missiles and was NASA's prime contractor for the Saturn V rocket that put men on the moon. More recently, Chrysler produced the M1 Abrams tank. And of course Chrysler is the keeper of the flame for Jeep, a 75-plus-years military legacy handed down from Bantam and Willys to Kaiser to AMC to Chrysler. The point of this history lesson is to note that in times of war or national emergency, America's industrial might has been called to serve, and may well be called on again.
