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

U.S. auto sales fall in July, as Detroit dials back on inventory, rental sales

DETROIT — U.S. carmakers said on Tuesday they continued to slash low-margin sales to daily rental fleets in July as General Motors, Ford and Fiat Chrysler Automobiles struggled to curb a slide in retail sales. July is on track to be the fifth straight month in which the annual pace of car and light truck sales declined from the same month a year ago, in part because of fewer fleet sales, analysts and industry executives said. July 2016 sales hit a strong 17.9-million-vehicle pace. GM said the seasonally adjusted annual sales rate fell to an estimated 16.9 million vehicles in July. At midmorning on Tuesday, GM shares were down 3.4 percent at $34.77, Ford was down 2.8 percent at $10.91, and Fiat Chrysler shares were down 0.3 percent at $12.05 in New York. GM sales dropped 15 percent from a year ago to 226,107 vehicles, as the company cut rental fleet sales more than 80 percent. The automaker said inventories of unsold vehicles at month's end were 104 days, down from 105 days at the end of June. GM has promised investors to reduce inventories to 70 days by year-end. Ford said its July sales dipped 7.5 percent to 200,212 vehicles, as it cut fleet sales more than 26 percent. Inventories fell to 77 days from 79 the previous month. Fiat Chrysler said sales dropped 10 percent to 161,477, as it also cut back sales to daily rental fleets. Among the top Japanese companies, only Toyota reported a year-to-year gain, with sales up 4 percent to 222,057 — just 4,000 units behind GM. Honda sales were down 1 percent to 150,980 — its first-quarter sales continuing to decline in North America but seeing a big increase in China. And Nissan sales fell 3 percent to 128,295. GM, Ford and Fiat Chrysler have cautioned that second-half financial results likely will be lower than first-half results, in part reflecting production cuts in North America and pricing pressures. The automakers this year have been deliberately dialing back sales to rental-car companies, which often generate little to no profit, while struggling to keep retail sales from sagging further, according to industry analysts. Industry consultant LMC cut its full-year forecast for new vehicle sales to 17 million vehicles. Automakers sold a record 17.55 million vehicles in the United States in 2016.

Toledo continues fight for Jeep Wrangler production, despite mayor's death

Where will the next-generation Jeep Wrangler be built? That's an open question, but it's one that the city of Toledo, OH desperately wants to be the answer to. The city suffered a major blow, though, with the death of Mayor Michael Collins earlier this month. Collins had been the city's biggest champion during talks with Fiat Chrysler Automobiles, before suffering a fatal heart attack on Feb. 6. But Collins' tragic death isn't dampening the city's desire to carry on as the home of the Wrangler. "The mayor's passing is tragic. But on Monday, when I came to work, I knew exactly what I needed to do and exactly what needed to be done," the city's director of development, Matt Sapara, told the Detroit Free Press. According to the Freep, Sapara said Toledo and the state of Ohio have delivered an outline of a development plan that would give FCA the ability to buy an extra 100 acres to expand the factory. This is to help accommodate FCA's targeted output of 300,000 to 350,000 next-generation Wranglers, up from the 240,000 the factory can make now. "Our target in the proposal is to provide a way to increase the production capacity to a number that allows Fiat Chrysler to meet its business model," Sapara told the Freep, adding that the land could be available later this summer. FCA, meanwhile, has shown a somewhat ambivalent attitude towards Toledo production, with CEO Sergio Marchionne openly discussing the pros and cons of continuing to build the Wrangler south of the Michigan border. "We are going to take a very hard look at this without ignoring what these guys have done," Marchionne told the Free Press at last month's Detroit Auto Show, adding that he'd like to keep production there, provided the cost of retooling is comparable to relocating to another facility.
