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

Chevy, GMC and Ram dealers are worried they'll run out of new pickups

One of the unexpected side effects of the ongoing coronavirus pandemic is a shortage of pickups at Chevrolet, GMC and Ram dealers. Supplies are running out, and the factories that build these trucks remain closed. Stores across the nation began increasing incentives in March, when the first stay-at-home orders were issued, in a bid to continue luring buyers into showrooms. They also launched online sales channels, or expanded their existing digital business. Sales nonetheless plummeted in April 2020, but in-demand vehicles, like the Ram 1500 and the Chevrolet Silverado, are still selling relatively well thanks in part to the aforementioned incentives. Pickups outsold sedans for the first time in April 2020, according to The Detroit News, by 17,000 units. The problem is that General Motors, Fiat Chrysler Automobiles (FCA), and Ford temporarily closed their factories in March. "The pipeline is very dry," said Mike Maroone, the CEO of a large dealership group named Maroone USA, in an interview with Automotive News. He told the publication his Chevrolet stores are sitting on a 30-day supply of the Silverado, which is one of America's best-selling vehicles. "That is a problem for us," he concluded. Coronavirus-related lockdowns and factory closures compound problems already faced by dealerships who represent General Motors-owned brands. They entered 2020 with a thinner inventory than a year earlier due to the 40-day United Auto Workers (UAW) strike that paralyzed the company late in 2019, and the 0%, 84-month offers announced in March have sapped supply. Ram wasn't affected by a strike, but it has relied heavily on generous incentives to move trucks off lots. Ford, on the other hand, limited incentives to 2019 models. Inventory levels differ greatly from region to region. The national average for the Silverado stood at an 82-day supply in March 2020, down from 120 in March 2019. Ram stores had a 114-day supply of the 1500 (compared to 134 a year earlier), while Ford bucked that trend with a 111-day supply versus 84 in 2019. Don't panic if you're in the market for a truck; we're not facing a complete drought. Automotive News added that America's light-duty pickup inventory could fall to 400,000 units by the end of May, and drop further to 260,000 units in June. For context, there were about 700,000 light-duty trucks in stock in May and June of 2019. That's unquestionably a sharp drop, but there will still be over a quarter of a million trucks to choose from.

EPA suspected Fiat Chrysler of using 'defeat device' in 2015

U.S. regulators told Fiat Chrysler Automobiles in November 2015 that they suspected some of the automaker's vehicles were equipped with secret software allowing them to violate emission control standards, according to emails disclosed on Friday. The U.S. Environmental Protection Agency and California Air Resources Board accused Fiat Chrysler in January of using the software, known as a "defeat device," to illegally allow excess diesel emissions in 104,000 Jeep Grand Cherokees and Dodge Ram 1500 trucks built between 2014 and 2016. Byron Bunker, director of the EPA's Transportation and Air Quality compliance division, said in a January 2016 email to Fiat Chrysler, obtained by Reuters under the Freedom of Information Act, that he was "very concerned about the unacceptably slow pace" of the automaker's efforts to explain high nitrogen oxide emissions from some of its vehicles. Nitrogen oxide is linked to smog formation and respiratory problems. Bunker's email said the EPA had told Fiat Chrysler officials at a November 2015 meeting that at least one auxiliary emissions control device on the car maker's vehicles appeared to violate the agency's regulations. Mike Dahl, head of vehicle safety and regulatory compliance for Fiat Chrysler's U.S. unit, responded in a separate email that the company was working diligently and understood the EPA's concerns. He added that if the EPA identified Fiat Chrysler vehicles as containing defeat devices it would result in "potentially significant regulatory and commercial consequences." The documents redacted the vehicles named, but two officials briefed on the matter said they referred to diesel models. The EPA's November 2015 meeting with Fiat Chrysler came two months after Volkswagen AG, mired in a major tailpipe emissions scandal, admitted to installing secret defeat device software in hundreds of thousands of U.S. diesel cars to make them appear cleaner than they were on the road.
