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 North American Car and Truck/Utility of the Year finalists announced [w/poll]

2012 is almost in the books and automakers are spending December gearing up for the 2013 auto show season, which tips off next month at the Detroit Auto Show. Traditionally, the latter opens up with the announcement of the North American Car and Truck/Utility of the Year awards, and this year figures to be no different.
But up until this moment, we didn't know which six vehicles would be parked ahead of the stage as finalists, with executives and engineers waiting for the winners to be disclosed. Whittled down from October's "short list" of nominees (11 cars and 10 truck/utility vehicles), the finalists are as follows:

2019 Ram 1500 truck Ram-o-rama: Many trims, options spotted on the road

We'll give Ram credit. It provided an impressive variety of 2019 Ram 1500 trucks to peruse at the Detroit Auto Show. There was a Big Horn Sport, Laramie, Limited and Rebel, with both the Quad Cab and Crew Cab on display as well. We even got to see both five- and six-passenger interiors. However, all that variety still only scratched the surface of the 2019 Ram. To help flesh things out a bit, spy photographers recently captured a bunch of 2019 Ram variations testing out on public roads. With the truck unveiled, camouflage was unnecessary, giving us unimpeded first looks at a number of trim levels, bed/cab combinations and options. Among these are the base level Ram Tradesman, which features blacked out plastic grille and other trim. There's also a single pic of the Ram Lone Star, which is really just what they call the Big Horn in Texas (look for the badge on the tailgate). We also got our first look both Big Horn and Laramie Quad Cabs with a long bed. In terms of options, there's a Big Horn with small, basic wheels and a Limited with the new bi-LED headlight option (have fun with those, oncoming traffic). There's also a Ram Rebel with a different hood that's missing the extra vents found on the truck at the auto show and in previously published pictures. Perhaps this is an option, perhaps its just the wrong hood placed on a test mule. We'll see. In any event, we'll know a lot more about all the different variants as the new Ram keeps inches closer to its on-sale date.
