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

Jeep still working to improve Cherokee's 9-speed auto

Fiat Chrysler is hoping an upcoming software update will stem the tide of consumer complaints surrounding its nine-speed automatic transmission. Owners of the 2014 Jeep Cherokee have reported a number of problems on the National Highway Traffic Safety Administration's SaferCar.gov website, since the new model and its troubled gearbox arrived way back in October 2013. The software update is "intended to keep the vehicle performing as intended, and to prevent durability issues from occurring in the future," an FCA spokesperson told Automotive News, and will be available to owners of both the 2014 to 2015 Jeep Cherokee and the 2015 Chrysler 200, which also uses the 9AT. While FCA will be notifying consumers of the update, owners can also request the software reflash if they happen into their dealer before then. Despite the widely documented problems with the transmission, the only complaints on NHTSA's website relate to the 2014 Cherokee – neither the 2015 Jeep nor the 200 have received any complaints. That bodes well as FCA prepares to begin deliveries of the 2015 Jeep Renegade and launch the Fiat 500X, both of which pair the 9AT with the 2.4-liter Tigershark four-cylinder. "We have had to do an inordinate amount of intervention on that transmission, surely beyond what any of us had forecast," FCA CEO Sergio Marchionne told Automotive News. "There are things that we have done – that we continue to do. Our proactive customer care intervention has actually increased in intensity on these vehicles in 2014, especially in the second half." What's fascinating about the 9AT's problems are that they haven't been the fault of manufacturer ZF, but have related to software that wasn't "mature" and had "teething problems," Marchionne has said previously, AN reports. With the lack of criticism for the 9AT in 2015 models and this pending software update, though, here's hoping that FCA has finally figured out its fuel-sipping gearbox. Related Video:

Wolverine will drive weird custom Chrysler 300 in next X-Men movie

Fiat Chrysler loves a movie tie-in. Remember the Stormtrooper-spec Dodge Charger we messed around with? Then there was the Jeep Renegade Dawn of Justice special edition, built for Batman v. Superman. And now, it looks like the company donated a misshapen Chrysler limo for the latest film in the Wolverine series. Some movie-stalking paparazzi caught Hugh Jackman next to this odd vehicle, and you can see photos at Just Jared, a celebrity gossip site. The photogs were more concerned with the graying star, who's reprising his role as the adamantium-boned superhero for the ninth time including cameos, but we'll focus on the machine. We can see the car's rear three-quarters and not a lot else. It looks broadly based on the 300, but much longer. The Chrysler winged badge is clearly visible on the trunk, while a retro script version of the automaker's logo sits on the rear pillar. There's also an unexplained "E8" badge to the right of the driver's side taillight. And as for those lamps, it's like FCA mashed together the current 300's taillights with those from a Cadillac CT6. The trunk and rear window are the strangest elements of all. We can't figure out what's happening with the tiny rear glass, the strange curve to it, or the tiny, sloping rear deck. It's ... not pretty. From the rest of what's visible, it's clear this particular car is a limo of some kind. The front end has been modified with fat fender flares sitting over some big multispoke wheels, and the door handles have been shaved. Behind the B-pillar, it gets weird. There's a long stretch of glass and bodywork, and then a very small rear door. Ingress and egress would be tough, to say the least. There's a lot of brightwork, too, from the wheels to the thick chrome strip running below the greenhouse and onto the hood. A couple of the images give a glimpse into the interior, which is wholly different from that in the production 300. We've embedded a tweet with some of the images below.
