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 Recalling 870,000 SUVs For Brake Defect

Chrysler is recalling nearly 870,000 SUVs because corrosion may make the vehicles' brakes harder to use. Jeep Grand Cherokee and Dodge Durango SUVs from the 2011 through 2014 model years are involved. Chrysler says crimp joints in the brake boosters can corrode if they're exposed to water. If the water freezes, the boosters won't aid braking as they usually do. Chrysler began investigating after some customers said their brakes felt too firm when pressed down. The company knows of one accident, but no injuries, due to the defect. Dealers will install a shield to protect the boosters for free and replace boosters that aren't working properly. Chrysler has since changed the design to make the boosters more corrosion resistant. Chrysler will notify owners of the recall, which involves 867,795 vehicles.

Detroit Three to lose dominance of North American auto output in 2017

DETROIT — North American vehicle production by the unionized Detroit Three automakers will fall behind the combined North American output of Tesla and automakers from Europe and Asia for the first time this year, IHS Markit forecast on Wednesday. In 2017, the Detroit Three could build 8.6 million vehicles in North America, while Tesla and foreign automakers build 8.7 million, IHS Markit analyst Joe Langley said. By 2024, the gap will widen, with Asian and European automakers and Tesla combining to build about 9.8 million vehicles in North America. General Motors, Ford and the North American operations of Fiat Chrysler Automobiles NV will combine to build 8.1 million vehicles, down 6 percent from this year. Mexico is on track to increase its share of North American vehicle production, Langley said, moving to 4.5 million vehicles a year by 2024 from about 4 million vehicles currently. The milestone for the growth of Tesla and foreign automakers in North America comes as the Trump administration is pushing to limit imports of vehicles from Mexico in negotiations to overhaul the North American Free Trade Agreement. The declining share of North American vehicle production for the Detroit automakers also challenges U.S. and Canadian unions that represent their workers. Canadian workers are on strike at a GM factory in Ontario to protest the automaker's decision to cut jobs and move to Mexico some production of sport utility models built there. Foreign automakers over the past year have announced plans for a wave of new or expanded plants in North America, while Tesla is ramping up to build as many as 500,000 cars a year at its plant in Fremont, Calif. Often referred to as "transplants," the foreign-owned factories are poised to become the mainstream of the North American auto industry. Automakers are increasingly using factories in China or Mexico to build vehicles that used to be assembled solely in the United States, Langley said. He cited as an example Ford's decision to shift production of the Focus small car for North America to a Chinese assembly plant.
