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 spends $1.5 billion to retool plant for Ram production

Fiat Chrysler Automobiles (FCA) is planning to invest $1.48 billion to retool its Sterling Heights Assembly plant in metro Detroit to build the next generation of the Ram 1500. The investment will allow the assembly plant to go from unibody to body-on-frame construction. FCA also confirmed that production of the Chrysler 200 will end in December in order for the plant to be altered. As previously reported, FCA is looking to move production of the 1500 from its current assembly plant in Warren to the Sterling Heights Assembly plant (both are in Michigan). While FCA has not released any official plans for the Warren Truck Assembly Plant, Automotive News reports that the plant will be retooled to manufacture the Jeep Wagoneer and Grand Wagoneer SUVs. Earlier this month, FCA announced plans to invest $1.05 billion to retool the Jeep Wrangler factory. FCA's current investment plans are part of the automaker's push to put competitive products on the road.

Government Ending Jeep Investigation

The government is closing its investigation into older-model Jeeps with fuel tanks that could rupture and cause fires. The National Highway Traffic Safety Administration said Friday it has "no reservations" with Chrysler Group's plans to recall the vehicles. The agency is expected to release a report on its investigation in a few weeks. The decision ends an unusually public struggle between Chrysler and NHTSA. The agency asked Chrysler to recall 2.7 million Jeeps last June, contending that their gas tanks - which are positioned behind the rear axle - were at risk of rupturing and catching fire in rear-end crashes. Involved were Grand Cherokee SUVs from the 1993 to 2004 model years and Liberty SUVs from 2002 to 2007. Chrysler initially refused to recall the vehicles. The company said the rate of fuel leaks and fires after crashes was similar to comparable vehicles that were sold during the time in question. It was the first time in two years that an automaker had refused NHTSA's request for a recall. Chrysler later agreed to recall 1.56 million of the Jeeps and install trailer hitches on them to help protect the gas tanks. The company sent notices to the remaining customers saying their vehicles were fine if they have factory-installed or Chrysler-made trailer hitches. NHTSA said late Friday that it has been in close contact with Chrysler and will monitor the recall as it continues. Chrysler has told customers that it will start installing the hitches soon. "Consumers should have their vehicles serviced promptly once they receive final notification from Chrysler,"NHTSA said in a statement. In its own statement Friday, Chrysler said, "We share NHTSA's commitment to safety." NHTSA's outgoing chief, David Strickland, told The Associated Press in an interview last month that Chrysler had convinced NHTSA that the Jeeps were no more dangerous than similar vehicles sold at that time. "Those vehicles performed at a rate similar to their peers. That is the keystone analysis as to whether something poses an unreasonable risk to safety," Strickland said. Friday was Strickland's last day at NHTSA. He is joining Venable, a law firm. NHTSA began investigating the Jeeps at the request of the Center for Auto Safety, a Washington-based advocacy group. "It is tragic that NHTSA approved Chrysler's sham trailer hitch recall for Jeeps that explode in rear impacts," the Center for Auto Safety's director, Clarence Ditlow, said Friday.
