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

Fiat Chrysler, Waymo expand partnership for Level 4 self-driving

Fiat Chrysler and Waymo, the self-driving unit of Google parent Alphabet Co., are expanding their partnership in an ambitious plan to develop fully autonomous commercial delivery vehicles and integrate Level 4 autonomous technology across the FCA fleet, the two companies said Wednesday. The agreement makes FCA (soon to be dubbed Stellantis when the PSA merger is complete) the exclusive partner for Waymo to develop and test self-driving Class 1-3 light commercial delivery vehicles. Initial efforts will focus on integrating the Waymo Driver system into the Ram ProMaster cargo van for commercial fleets, including Waymo Via, which have seen demand for home delivery services mushroom during the coronavirus pandemic. Conversely, FCA has tapped Waymo as its exclusive supplier for Level 4 self-driving technology across its vehicle fleet, opening up possibilities for ride-hailing and personal-use vehicles. An FCA spokesman would not commit to any timelines for integrating Waymo’s self-driving technology into the ProMaster or other brands or models. The Society of Automotive Engineers defines Level 4 systems as fully automated driving, though a human driver can manually override and take control of the wheel. There are currently no Level 4 autonomous vehicles offered to customers, and most experts believe the technology still faces many obstacles to broad adoption and regulatory clearance. Fiat Chrysler first partnered with Waymo in 2016. The two companies have worked to test WaymoÂ’s Level 4 technology using retrofitted Chrysler Pacifica Hybrid minivans. “Our now four-year partnership with Waymo continues to break new ground,” Mike Manley, Fiat ChryslerÂ’s CEO, said in a statement. “Incorporating the Waymo Driver, the worldÂ’s leading self-driving technology, into our Pacifica minivans, we became the only partnership actually deploying fully autonomous technology in the real world, on public roads.” Waymo recently introduced its fifth generation of the Waymo Driver system, which it completely redesigned to be able to handle more environments and situations. It combines 360-degree lidar sensors positioned atop the vehicle and at four points around the sides, plus cameras and radars. Waymo said it had already manufactured the new sensors and integrated them onto Jaguar I-Pace test vehicles.

Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.
