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

NHTSA questions FCA's reaction to recalls, will hold public hearing

The US Department of Transportation and National Highway Traffic Safety Administration are holding a public hearing on July 2 to investigate whether FCA US is failing to fix safety problems and issue necessary notices. The agencies also want detailed accounts of the handling of 20 recalls by June 1 as part of a special order. If the Feds determine that the automaker isn't living up to its legal requirements, the result could go as far as a "buy-back or replacement of affected vehicles." "Significant questions have been raised as to whether this company is meeting its obligations to protect the drivers from safety defects, and today we are launching a process to ensure that those obligations are met," NHTSA administrator Mark Rosekind said in the announcement of the hearing. The 20 recalls that the agencies are investigating date from between 2013 and 2015. Just some of these include the action to make the fuel tanks safer on the Jeep Grand Cherokee and Liberty; FCA US' Takata inflator repairs; inadvertently deploying airbags in the Liberty, Grand Cherokee and Dodge Viper; and the company's ignition switch fix for the Chrysler Town & Country, Grand Caravan and Journey. Failure to submit reports about all of these on time could result in a $7,000 per day fine. You can read the whole list in the PDF for the special order. In a statement to Autoblog, FCA US said, "The average completion rate for FCA US LLC recalls exceeds the industry average and all FCA US campaigns are conducted in consultation with NHTSA. The Company will cooperate fully." The government agencies claim that they have received complaints from customers alleging that they weren't notified of recalls; parts not being available; difficulty getting an appointment, and misinformation from dealers. During the hearing witnesses from FCA US, NHTSA and the public have the opportunity to present evidence on each campaign.
