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

FCA US under-reported death and injury claims to NHTSA

The National Highway Traffic Safety Administration says FCA US significantly under-reported death and injury claims due to flaws in its early warning system. The government first discovered a potential problem with the automaker's reporting in late July, and FCA US has been investigating the issue since. NHTSA claims that the problem appears linked to the way the company gathers and reports safety information. The agency is still investigating how serious the flaws are and their causes. "This represents a significant failure to meet a manufacturer's safety responsibilities," NHTSA Administrator Mark Rosekind.Rosekind said in a statement. FCA US admits that it "identified deficiencies" in the reporting, but in a statement the company said that it notified NHTSA of the issue immediately. The company promised that it is taking this problem "extremely seriously" and pledged to remedy the situation. In late July, FCA US was hit with a potential $105-million fine by NHTSA for the way the automaker conducted some recalls. As part of that agreement, the company also consented to more rigorous oversight by safety regulators in the future and a buy-back of some affected vehicles. Other automakers have been punished for failing to submit EWR data. Honda incurred a $70 million fine in January from NHTSA for missing 1,729 incidents over 11 years. Ferrari had to pay $3.5 million in 2014 for not sending them in for three years. Statement from NHTSA Administrator, Mark Rosekind, on Fiat Chrysler Automobiles' under-reported discrepancy in FCA's Early Warning Report data September 29, 2015 "In late July, NHTSA notified Fiat Chrysler Automobiles of an apparent discrepancy in FCA's Early Warning Report data. FCA has informed NHTSA that in investigating that discrepancy, it has found significant under-reported notices and claims of deaths, injuries and other information required as part of the Early Warning Reporting system. Preliminary information suggests that this under-reporting is the result of a number of problems with FCA's systems for gathering and reporting EWR data. This represents a significant failure to meet a manufacturer's safety responsibilities. NHTSA will take appropriate action after gathering additional information on the scope and causes of this failure." – Mark Rosekind, NHTSA Administrator.

Jeep Renegade's development a template for new Fiat Chrysler Auto

"We figured we'd take the best of both worlds." - Ralph Gilles.
The international makeup of the 2015 Jeep Renegade will serve as a template for cooperation within the newly formed Fiat Chrysler Automobiles, Senior Vice President of Product Design Ralph Gilles said.
