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

Ram's newest Power Wagon looks even more outlandish for 2014 [w/video]

The newest Ram Power Wagon is arguably the most imposing vehicle to be shown at the 2014 New York Auto Show, boasting a number of new aesthetic features, as well as a new graphics package.
Ram added a 6.4-liter V8 as an optional engine for 2014, but in the Power Wagon, it's the sole powerplant, boasting 410 horsepower and 429 pound-feet of torque. An equally robust six-speed automatic backs up the brawny engine, while 4.10 gearing, an 11.5-inch rear axle and electronically locking front and rear diffs come standard.
A new five-link coil rear suspension and Bilstein monotube shocks should deliver a pretty comfortable ride, while the Power Wagon's off-road ability is complemented by the new Articulink system on the front suspension, which offers electronic sway-bar disconnect. 33-inch Goodyear rubber comes standard.

Chrysler flooded with over 8,000 Ram 1500 EcoDiesel orders in 3 days

The diesel, half-ton pickup has long been a Holy Grail to many truck fans, largely because of its potential to achieve both high payload and great fuel economy. Strange, then, that auto companies have seemingly been slow to react. However, Chrysler is finally wading into the pool for the 2014 model year with a version of its Ram 1500 pickup, and early claimed returns are showing the advantage of being first on the market. The Auburn Hills automaker has just revealed that its initial allocation of 8,000 EcoDiesel trucks has been filled by dealers in just three days.
That flood of orders came from February 7-10, and that strong surge of interest apparently amounts to a new Ram record for the number of customer orders placed for a vehicle in such a short period of time. In fact, EcoDiesel models accounted for over half of Ram 1500 orders over that period, despite the fact that the diesel option costs several thousand dollars more than a comparable gasoline-engined model. That impressive total did not come entirely as a shock to Ram officials, however: "We knew customers have been asking for it," Nick Cappa, Ram Truck communications officer, tells Autoblog.
The 2014 Ram 1500 with its 3.0-liter EcoDiesel V6 and standard eight-speed TorqueFlight automatic makes 240 horsepower and 420 pound-feet - a combination good for 9,200 pounds of towing. Despite that pulling power, its fuel economy is rated at 28 miles per gallon highway (the best among trucks in its class), 20 mpg city and 23 mpg combined. Four-wheel drive variants gives up a single mpg in all categories.
