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

Chrysler's internal documents question Ram quality as workers protest

Chrysler is reportedly having a hard time ramping up production of its 2013 Ram 1500. According to The Detroit News, only 16 of the 58 trucks built at the Warren Truck Assembly Plant during the model's first hour passed final inspection. While quality eventually improved over the course of the day, just over half of the units built on Thursday were approved for shipment. Even with workers ordered to stay late to fix their mistakes, some 1,078 units remained outside the facility with defects. The problem, according to workers at the plant, is morale.
According to the report, Chrysler recently changed the shift schedule at the plant and workers are unhappy with the new situation. The new plan has workers split into three shifts, each covering four 10-hour days. With the shifts staggered, some workers now have to work nights and on Saturdays. Some employees are so upset that they've taken to protesting, though the move isn't sanctioned by the United Auto Workers.
Meanwhile, Chrysler admits there were internal issues with the launch, but that the company was able to contain them. A spokesperson has said "plant quality indicators are getting progressively better."

2015 Ram ProMaster City Tradesman First Drive [w/video]

From the perspective of a reviewer, there's a refreshing clarity to be hand when approaching a vehicle like a small commercial van. Where the inherent value equation for most vehicles is composed of both objective facts (price, fuel economy), and subjective opinions (looks, emotional response while driving), the reckoning of something like the new Ram ProMaster City is more straightforward. The light commercial van segment in the US has seen a remodel over the last half-decade, moving from paneled-over minivans to the versatile, economical, European-style boxes on wheels you see with increasing frequency today. Ford, Nissan and Chevrolet are all players here (though Chevy's City Express is essentially a rebadged version of Nissan's NV200), and though Ram's entry could be seen as late to the party, it also matches up very nicely in many of those straightforward areas of measure. Kindly, Ram brought along both the Nissan and the Ford for us to test alongside its new product, so we could get firsthand comparative impressions. The 2015 ProMaster City is roomier, more powerful and more maneuverable than its competition, though it trades those advantages for a higher price and a thirstier engine around town. We headed down to Texas where, between breaks for tacos and Topo Chicos, our goal was to see if Ram had created the new best box van in the US. Based on the already successful Fiat Doblo van from Europe, the baby ProMaster's visual transformation after its continental hop isn't radical. Ram has fitted a crosshair grille, new headlights and taillights, but largely the curvaceous, nose-forward styling remains the same. As we mentioned at the top: style is going to be very low on this list of priorities for a buyer of light commercial vans. Still, we'd rate the City as mid-pack for the options in the US; more attractive than the Nissan/Chevy twins and less so than the crisp Ford Transit Connect. (Though the optional five-spoke wheels of our test vehicle make it seem downright sporty in this group). Open the driver's side door and slide into the almost totally flat front seat, and any notion of "style" goes right out the window. Surfaces are almost exclusively black and gray, with workaday textures and frustratingly easy-to-scratch-plastics. This is a functional space though; trays, cubbies, cupholders and bins are far more numerous than you'd expect from a compact, two-seat cabin.
