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

Ford, Stellantis workers join those at GM in ratifying contract that ended UAW strikes

DETROIT — The United Auto Workers union overwhelmingly ratified new contracts with Ford and Stellantis, that along with a similar deal with General Motors will raise pay across the industry, force automakers to absorb higher costs and help reshape the auto business as it shifts away from gasoline-fueled vehicles. Workers at Stellantis, the maker of Jeep, Dodge and Ram vehicles, voted 68.8% in favor of the deal. Their approval brought to a close a contentious labor dispute that included name-calling and a series of punishing strikes that imposed high costs on the companies and led to significant gains in pay and benefits for UAW workers. The deal at Stellantis passed by a roughly 10,000 vote margin, with ballot counts ending Saturday afternoon. Workers at Ford voted 69.3% in favor of the pact, which passed with nearly a 15,000-vote margin in balloting that ended early Saturday. Earlier this week, GM workers narrowly approved a similar contract. The agreements, which run through April 2028, will end contentious talks that began last summer and led to six-week-long strikes at all three automakers. Shawn Fain, the pugnacious new UAW leader, had branded the companies enemies of the UAW who were led by overpaid CEOs, declaring the days of union cooperation with the automakers were over. After summerlong negotiations failed to produce a deal, Fain kicked off strikes on Sept. 15 at one assembly plant at each company. The union later extended the strike to parts warehouses and other factories to try to intensify pressure on the automakers until tentative agreements were reached late in October. The new contract agreements were widely seen as a victory for the UAW. The companies agreed to dramatically raise pay for top-scale assembly plant workers, with increases and cost-of-living adjustments that would translate into 33% wage gains. Top assembly plant workers are to receive immediate 11% raises and will earn roughly $42 an hour when the contracts expire in April of 2028. Under the agreements, the automakers also ended many of the multiple tiers of wages they had used to pay different workers. They also agreed in principle to bring new electric-vehicle battery plants into the national union contract. This provision will give the UAW an opportunity to unionize the EV battery plants plants, which will represent a rising share of industry jobs in the years ahead.

Fiat Chrysler recalls 4.8 million U.S. vehicles for cruise control defect

WASHINGTON - Fiat Chrysler said on Friday it is recalling 4.8 million U.S. vehicles over a defect that could prevent drivers from deactivating cruise control and warned owners not to use the function until they get software upgrades. The Italian-American automaker said no injuries or crashes are related to the large recall campaign but said it had one report of a driver of a 2017 Dodge Journey rental car unable to deactivate the cruise control. Fiat Chrysler, which in 2015 was hit with penalties from U.S. regulators totaling $175 million for safety lapses, did not say how much the recalls would cost. The recall addresses what Fiat Chrysler called an "extremely rare" series of events that could lead to drivers being unable to cancel cruise control. The National Highway Traffic Safety Administration (NHTSA) said on Friday it "strongly encourages vehicle owners to follow a warning" to stop using cruise control on the recalled vehicles until repaired. NHTSA said drivers could overpower the system by forcefully applying the brakes until the vehicle stopped. Fiat Chrysler also said the vehicle could be stopped by shifting into neutral and braking. Fiat Chrysler shares fell more than 2 percent in premarket trading in New York on the recall. Fiat Chrysler noted that at times cruise control systems automatically initiate acceleration to help vehicles maintain driver-selected speeds, including when going up an incline. If an acceleration occurs simultaneously with a short-circuit in a specific electrical network, a driver could be unable to deactivate the function. Fiat Chrysler said vehicles may be placed in park once stopped, at which point cruise-control is canceled. The recall involves a group of gasoline-powered vehicles with automatic transmissions from various model years built from 2014 through the 2019 model year. Most of the vehicles being recalled cover the 2014-2018 model years. Among the vehicles being recalled are the Chrysler 200, Chrysler 300, Chrysler Pacifica, Dodge Charger, Dodge Challenger, Dodge Journey, Dodge Durango, Jeep Cherokee, Jeep Grand Cherokee, Jeep Wrangler and Ram 1500, 2500 and 3500 pickup trucks and Ram 3500/4500/5500 cab chassis trucks. Fiat Chrysler made the announcement going into the busy Memorial Day weekend, which traditionally kicks off the summer driving season.
