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 recalls over 200k Jeep Cherokees for windshield wiper static

Fiat Chrysler Automobiles is issuing a recall for over 200,000 versions of the 2014 Jeep Cherokee due to a problem with static buildup disabling the windshield wipers. FCA has identified 158,671 units in the United States. Another 18,366 vehicles are estimated to be affected in Canada, a further 3,582 in Mexico, and 26,049 outside of North America. The problem, according to the first statement below, results from static building up if the wipers are operated in dry conditions. The static could mess with the wipers' control module, rendering them disabled. To fix the problem, dealers will be instructed to install a ground strap to the module. In parallel, FCA is also offering incentives to the owners of certain trucks that were subject to recall but for which remedies were not immediately available. To encourage those owners to bring their older vehicles in for the required service, the automaker will disperse $100 prepaid cards for use at their discretion. The program is offered to owners of certain model year Jeep Grand Cherokee, Jeep Liberty, Chrysler Aspen, and Dodge Durango sport-utility vehicles, as well as certain Dodge Dakota and Ram trucks. Owners of the affected Grand Cherokees will have the option instead to take a $1,000 consideration toward the purchase of a new vehicle or for parts and service. The offers are only being extended under certain specific criteria, though. So if you think that could be you, you'll want to read through the conditions in the second announcement below. STATEMENT: CONTROL MODULE August 31, 2015 , Auburn Hills, Mich. - FCA US LLC is recalling an estimated 158,671 SUVs in the U.S. to help protect their control modules from static buildup that may potentially disable the vehicles' windshield wipers. An investigation by FCA US discovered static buildup may occur if the vehicles' windshield wipers are activated during dry conditions. Significant static buildup may affect a control module that powers the wipers. The Company is unaware of any related injuries or accidents. Affected are model-year 2014 Jeep Cherokee SUVs. An estimated 18,366 vehicles will be recalled in Canada, as will an estimated 3,582 in Mexico and 26,049 outside the NAFTA region. Dealers will install a ground strap to the control module to eliminate the potential for static buildup. Customers will be advised when they may schedule service, which will be performed at no cost.

Ram readying radical two-way split tailgate?

Ram may be preparing a new sort of tailgate that could rethink the way we access the bed of the company's pickup trucks. Rather than the typical fold-down tailgate that we know so well, patent drawings show a tailgate that combines the functionality of a traditional fold-down design with a 50/50 split that can, individually, be opened like a barn-door design or dropped flat like a standard tailgate.
Now, Ram is far from the first to toy around with something like this. The most obvious example is the Honda Ridgeline, which features a single-piece tailgate that is double-hinged so that it can open traditionally or be swung out to the side. The big news here is the split and the fact that each half can be used independently of the other. Unlike the Honda, the individual halves would be operated via touchpads.
The implications of this new design aren't entirely clear right now. It seems possible that the rendering could just be for a concept vehicle, but production is certainly possible as well - Ram has shown a real willingness to innovate in the pickup segment as of late, with features like coil-spring rear suspensions, light-duty diesels and the Ram Box bedside storage system.
