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 performance could be electrified, new hybrid transmissions coming

Dodge is arguably the last company around specializing in old-school muscle cars. Outside of a few models like the Chrysler Pacifica Hybrid and the new e-Torque offerings in the Ram 1500 and Jeep Wrangler, FCA as a whole seems behind the ball when it comes to green or electrified powertrains. That might change over the next few years, as Tim Kuniskis, head of passenger cars at FCA, told Automotive News that he sees the future of performance to be electrified.  At the reveal of the Dodge Charger Hellcat Widebody a few weeks back, Kuniskis said "the absolute future is electrification of these cars." What form this takes or how soon this all might happen is unclear, but changes are likely coming. Kuniskis said the electrified models could be anything from pure battery-electric vehicles to plug-in hybrids to e-axles. FCA’s e-torque system already works with the companyÂ’s Hemi V8 in the Ram 1500, so, if thereÂ’s room in the engine bay, we imagine it would be pretty easy to adapt the mild-hybrid system for other V8-powered vehicles.  One thing to note is that FCA just inked a new deal with ZF. The latter will supply a new 8-speed automatic transmission for longitudinal front-engine cars that will work with both rear and all-wheel drive vehicles. FCA already uses a version of the ZF 8HP automatic, but the big thing to note is that the new transmission has a small electric drive unit built in. If this new transmission is as ubiquitous as the current one, you might find electrified versions of Alfa Romeo and Maserati products as well as those from Dodge, Jeep and Ram. This seems in line with what was announced in last yearÂ’s five-year plan.

Ranking Dodge's Charger Hellcat with the fastest sedans in the world

"This is a car that most brands would never bring to market." - Tim Kuniskis
Dodge CEO Tim Kuniskis had reason to be confident, perhaps even a bit cocky at the reveal of his brand's newest halo car, the 2015 Dodge Charger SRT Hellcat. As he said simply, it's the "quickest, fastest and most powerful sedan in the world."
