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

The Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages. Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension. The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself. An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability. Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues. Hardware: 35 percent lower rate front springs/28 percent lower rate rear springs 75 percent lower rate hollow front sway bar/44 percent lower rate rear sway bar Drag-tuned Bilstein Adaptive Damping Shocks Software: Rear = F/F and Front = F/S F/F – F/S maintained @ wide open throttle (WOT) F/F – F/F < WOT Traction control disabled/ESC maintained Result: 13.5=575@500 Related Video: This content is hosted by a third party.

Killing the Dart and 200 might lower FCA's fuel economy burden

Killing the Dodge Dart and Chrysler 200 could allow FCA US to take advantage of an intriguing quirk in the next decade's fuel economy regulations. By increasing its ratio of trucks versus cars, the automaker might not need to worry so much about hitting the more stringent efficiency rules. At first thought, it might seem harder for an automaker with a ton of trucks to meet the government's mandated 54.5 mile per gallon corporate average fuel economy for 2025. However, every company doesn't need to hit that lofty figure, according to The Detroit Free Press. The exact target varies by the product mix between trucks and cars. "While passenger car and light truck categories have separate CAFE targets, it's still true that more trucks versus cars in a company lineup means a lower combined CAFE target," Brandon Schoettle, Project Manager Sustainable Worldwide Transportation at the University of Michigan Transportation Research Institute, told Autoblog. "While passenger car and light truck categories have separate CAFE targets, it's still true that more trucks versus cars in a company lineup means a lower combined CAFE target." FCA US' current product blend has 80 percent pickups and CUVs, which means the company stands to benefit from a lower fuel economy target. It might not seem entirely fair environmentally, but this is a great move from a business perspective. The new CAFE rules aren't set in stone, according to The Detroit Free Press, but potentially taking advantage of the regulation is just one more reason to cut the Dart and 200. Modern crossovers also aren't gas guzzlers like older SUVs, which could make it easier to hit the fuel economy target. "Utilities offer practicality and versatility that cars do not, and now, built on car architectures, they do not penalize consumers on fuel economy as they once did," AutoTrader Senior Analyst Michelle Krebs told Autoblog. Schoettle warns that FCA is still making a gamble by killing the small sedans. "Depending on the previous sales volumes and how much these vehicles might have exceeded their specific CAFE targets, it's possible that these cars helped earn CAFE credits for FCA that they could bank for future use," he said.
