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 trucks lead 2021 J.D. Power Initial Quality Study

For the first time ever, Ram leads in J.D. Power's annual Initial Quality Study with a score of 128 PP100, or problems experienced per 100 vehicles in the first 90 days of ownership. Ram was in third place in last year's rankings. Coming in second place is Dodge (139 PP100), a sister division to Ram under the Stellantis umbrella, followed by Lexus (144 PP100), this year's highest-ranked premium automaker, in third. These findings reinforce an overall trend over the last few decades where mass-market brands have outperformed premium brands that tend to introduce bleeding-edge technologies that can confuse owners or fail to work entirely. Genesis (148 PP100) is the only other premium automaker to perform better than average. At the bottom of the official rankings is Chrysler (251 PP100), which seems to make little sense considering most of its technologies are shared with Dodge and many with Ram until you consider that Chrysler only offers two platforms and one of them is the Pacifica/Voyager minivan twins that are unique to the brand. The next worst are Audi (240 PP100) and Volkswagen (213 PP100). Tesla would fall in between VW and Audi with its score of 231PP100, but because the electric car manufacturer doesn't provide access to J.D. Power in every state, it's not officially included. Interestingly, J.D. Power said on a followup call that the problems that Tesla owners report most often are more traditional issues, such as panel fitment, interior noises or paint problems instead of problems with the car's electronics. According to J.D. Power, the industry averaged a score of 162 PP100. That is four points higher than the overall score in 2020, and 20 of 32 brands improved their quality scores over the last year. That's a two percent increase in quality in 2021, which is good but slightly lower than the average rate of improvement over the last decade. On a car-by-car basis, the Nissan Maxima leads the overall field with a score of 85 PP100. Issues with infotainment systems — and in particular problems pairing smartphones with in-car technologies — continue to be the top-reported problems. Headaches connecting Apple CarPlay and Android Auto dominate the complaints. "Owners want wireless connectivity, and the industry has responded," according to Dave Sargent, vice president of automotive quality at J.D. Power. "However, this has created a bigger technical challenge for both automakers and tech companies.

Ram confirms Fiat Doblo-based ProMaster City for North America

As Sergio Marchionne flies back and forth between Turin and Auburn Hills, he doesn't just bring Chryslers back with him to Italy to sell as Lancias. He also brings Fiat products to sell Stateside under various Chrysler labels, chief among them Ram.
The former Dodge truck brand launched the Fiat Ducato as the Ram ProMaster earlier this year, giving it a greater foothold in the commercial vehicle market and a replacement for the Sprinter which Mercedes-Benz took back from its Chrysler-partnership days. Now Auburn Hills has announced that Ram will begin selling the Fiat Doblo on this side of the Atlantic as the Ram ProMaster City.
The Doblo, which was twice named International Van of the Year, has sold over 1.3 million units worldwide. Whether that includes the rebadged version which Vauxhall and Opel sell as the Combo is another matter, as is the question over how much longer Fiat and General Motors will continue that particular partnership as the ties between Fiat and Chrysler deepen.
