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

UAW warns automakers: Restarting U.S. plants is 'too soon and too risky'

WASHINGTON/WARREN, Mich. — The head of the United Auto Workers union on Thursday said it was "too soon and too risky" to reopen auto plants and Michigan's economy in early May, citing insufficient scientific data and coronavirus testing to assure workplaces are safe. The warning from UAW President Rory Gamble on Thursday afternoon came as General Motors Co , Ford Motor Co and Toyota Motor Corp took new steps toward reopening North American vehicle manufacturing operations in an environment where consumer demand is uncertain and worker safety paramount. The union has said that 24 of its members have died from Covid-19, though it was unclear whether they might have become infected in the workplace. Unionized Detroit automakers and non-union German and Asian automakers have been preparing to restart U.S. vehicle making operations by early May. Companies have shifted reopening dates amid uncertainty about government stay-at-home orders. Gamble's statement appeared to derail plans by the Detroit Three to start bringing UAW workers back to vehicle manufacturing jobs on May 4. The longer the automakers cannot produce profitable U.S.-made trucks and sport utility vehicles, the longer they burn cash. The UAW leader's statement was also aimed at Michigan Gov. Gretchen Whitmer, who has come under pressure from conservative groups and President Donald Trump to ease coronavirus stay-at-home restrictions. "At this point in time, the UAW does not believe the scientific data is conclusive that it is safe to have our members back in the workplace. We have not done enough testing to really understand the threat our members face," Gamble said. "We strongly suggest to our companies in all sectors that an early May date is too soon and too risky to our members, their families and their communities." Gamble said the union was "happy with the auto companiesÂ’ response and cooperation on working through the health and safety protocols we will need in the workplace when it is appropriate to restart." Earlier Thursday, GM began notifying front line managers to come back to work next week to get trained on new safety protocols designed to prevent the spread of the novel coronavirus as workers return to plants.

2015 Chrysler 200 production gets underway [w/videos]

Chrysler announced recently that it has added some 800 new jobs at its Sterling Heights Assembly Plant (SHAP) to support the production of its all-new 2015 Chrysler 200 sedan. Total employment at the Sterling Heights, MI plant grows to almost 2,800 with the hires, an impressive figure for a plant that was slated for closure in 2010.
Speaking to a crowd of employees and community leaders, Fiat-Chrysler CEO Sergio Marchionne was on hand to celebrate the kick-off of 200 production last week. "We're making a big bet on its success," said Marchionne of the sedan, "we've invested nearly a billion dollars in this facility."
That billion-dollar bill has been used to construct a spanking new paint shop, install a new body shop and install "machinery, tooling and material-handling equipment" according to the Chrysler press release. The company says that SHAP now runs to nearly five million square feet of manufacturing space - loads of room for all the new employees to do their thing - and that the facility can handle multiple vehicles on two unique architectures.
