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

Fiat Chrysler Automobiles recalls nearly 750k vehicles in two campaigns

Fiat Chrysler Automobiles is recalling a total of 747,817 vehicles in the US in two separate campaigns recently added to the National Highway Traffic Safety Administration database.
The first one covers about 434,581 units of the Chrysler 300, Dodge Charger, Challenger, Durango, and Jeep Grand Cherokee from the 2011-2014 model years with electric hydraulic power steering, the 3.6-liter V6 engine and a 160 amp alternator, according to FCA. In the affected vehicles, it's possible for the alternator to fail without warning and possibly cause the car to stall. According to the documentation submitted to NHTSA, the automaker began investigating the problem in August 2014 and has found possible evidence of one crash caused by the failures but no known injuries.
Customers will begin receiving notification about the recall next month, and obviously the repairs will be done at no cost to them.

Marchionne says no offers are on the table for Fiat Chrysler

MONZA, Italy (Reuters) - Fiat Chrysler (FCA) has not received any offer for the company nor is the world's seventh-largest carmaker working on any "big deal", Chief Executive Sergio Marchionne said on Saturday. Speaking on the sidelines of the Italian Formula One Grand Prix, Marchionne said the focus remained on executing the company's business plan to 2018. Asked whether FCA had been approached by someone or whether there was an offer on the table, he simply said: "No." The company's share price jumped to record highs last month after reports of interest for the group or some of its brands from China. China's Great Wall Motor Co Ltd openly said it was interested in FCA, but had not held talks or signed a deal with executives at the Italian-American automaker. The stock move was also helped by expectations that the company might separate from some of its units. Marchionne reiterated on Saturday that FCA was working on a plan to "purify" its portfolio and that units, such as the components businesses, would be separated from the group. He hopes to complete that process by the end of 2018. "There are activities within the group that do not belong to a car manufacturer, for example the components businesses. The group needs to be cleared of those things," he told journalists. Asked whether an announcement could come this year, Marchionne said it was up to the board to decide and that it would next meet at the end of September. He said the time was not right for a spin-off of luxury brand Maserati and premium Alfa Romeo and the two brands needed to become self-sustainable entities first and "have the muscle to stand on their feet, make sufficient cash". "The way we see it now, it's almost impossible, if not impossible, to see a spin-off of Alfa Romeo/Maserati, these are two entities that are immature and in a development phase," he said. "It's the wrong moment, we are not in a condition to do it." He said the concept of separating the two brands from FCA's mass market business made sense and did not rule out this happening in future, but not under his tenure, which lasts until April 2019. "If there is an opportunity in future, it would certainly happen after I'm gone. It won't happen while Marchionne is around," he said.
