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

2013-14 Dodge Viper recalled over faulty door handles

The 2013-14 Dodge Viper is getting a voluntary recall affecting 1,762 cars worldwide to replace their door-handle assemblies. Of the affected vehicles, FCA US reports there are 1,451 in the US, 160 in Canada, 17 in Mexico and 59 of them outside of NAFTA. After receiving three reports of doors either not closing or opening while driving a low speeds, FCA US engineers found a new sealant from a supplier didn't provide sufficient moisture protection to the electronic switches for the door latches. If the parts get wet, this can potentially cause a short circuit. The automaker is quite clear that are no reports of accidents of injuries from this problem. As always, the recall repairs will be done at no cost to owners, and FCA US will be getting in touch with customers soon about the problem. Related Video: Statement: Door-handle Assemblies April 9, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 1,762 cars globally to replace their door-handle assemblies. FCA US launched an investigation after the Company received three warranty claims linked to doors that failed to close or opened inadvertently while vehicles were moving at low speed. The Company is unaware of any related injuries or accidents. Engineers determined a sealant, newly adopted by a supplier, provided inconsistent moisture protection to the electronic switches that control the door latches. Switches exposed to moisture may short-circuit. Affected are approximately 1,451 model-year 2013-14 Dodge Viper SRT cars in the U.S.; 160 in Canada; 17 in Mexico and 59 outside the NAFTA region. Affected customers will be notified and advised when they may schedule service, which will be performed at no cost. Customers with questions may call the FCA US Customer Information Center at 1-800-853-1403.

Ram exec: first 30-mpg pickup truck will 'win'

It is totally possible, today, to take the Ram 1500 EcoDiesel pickup truck, load it up with gear and people, and drive it from Texas to Michigan while getting 38 miles per gallon. We know because we did it. Officially, though, the 1500 gets just 20 mpg combined. A more impressive number is the 28 mpg on the highway. Bob Hegbloom, the Ram brand director, thinks that there's a more important fuel economy target to hit: 30 mpg. Whichever truck company can manage that feat, he recently told Automotive News, "wins." It's kind of an obvious thing to say, but in the 1500 with both the EcoDiesel and the V6 Pentastar engine, Hegbloom said, "fuel economy is so important." Hegbloom didn't promise that the next EcoDiesel truck will manage to get on up over the 30 hump, but he did say that Ram is not sitting still when it comes to fuel economy. "I just want to have continuous improvement and to keep gaining every day," he said. "We sat still in the past and it doesn't lead to a great place."
