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

Chrysler honors Arsenal of Democracy's 75th anniversary

The Allied victory in World War II wouldn't have been possible without the Arsenal of Democracy. This phrase, originally coined by President Franklin D. Roosevelt 75 years ago today, described the war-time transformation of US manufacturing, especially the auto industry, to produce tanks and planes instead of cars and trucks. One of the earliest purpose-built facilities was the Albert Kahn-designed Detroit Arsenal, located in suburban Warren, MI, literally across the street from the future site of the General Motors Technical Center. Built by Uncle Sam, the plant churned out M3 Grant and M4 Sherman tanks with frightening speed, but it wouldn't have been possible without Chrysler. The company (which is ironically now allied to a former supplier of Nazi Germany and fascist Italy) operated the plant and applied automotive mass-production techniques to producing the government-designed tanks. The plant was so successful, according to Fiat Chrysler historian Brandt Rosenbusch, that it singlehandedly outpaced the entire Third Reich's tank production by 5,000 units over the course of the war. The Detroit Arsenal was also responsible for a quarter of all American tank production during the war. And like so many wartime factories, women formed a large percentage of the workforce, as men were drafted out of assembly work and into the armed forces. Chrysler has commemorated the 75th anniversary of the Arsenal of Democracy speech with a video on the Detroit Arsenal and its role there. And as for the site today? It built tanks up until 1997, and still serves as the home of the US Army's TACOM (Tank-automotive and Armaments Command) Life Cycle Management Command, a major site for tank research and development.

Detroit 3 small cars lay an egg in latest Consumer Reports reliability study

Consumer Reports has released its Annual Auto Reliability Survey and the results are, in a word, interesting. While we already covered the score-damaging effects of infotainment systems, there's another big angle to the data that's getting some attention - the utterly dismal scores of the Detroit Three's small car offerings.
The turbocharged Dodge Dart and Chevrolet Cruze, as well as the Ford Fiesta were their respective brands' lowest-scoring models, a stat that's made worse by the fact that the American automakers finished 25th, 21st and 23rd, respectively.
That's not acceptable for The Detroit Free Press' auto critic, Mark Phelan, who has penned a scathing critique of the D3's small car reliability scores, arguing that GM, Ford and Chrysler are "out of excuses."
