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

2019 Ram 1500 finally revealed | All new, from headlights to hybrid system

Few categories are as hotly contested as the full-size truck segment. The passion from both automakers and loyal truck owners is fierce. See any number of Calvin window decals for example. Well, a new Ram 1500 is finally here, and it's lighter, stronger and better equipped than ever before to take on the Ford F-150 and the Chevy Silverado. In addition to new styling and a hugely versatile interior, both the V6 and V8 Ram 1500 are available with a 48-volt mild-hybrid system. Despite looking similar to the current Ram, this isn't merely an update. The truck is all new inside and out, improving on what worked and fixing what was aging. Overall weight is down 225 pounds, with 120 of those coming from the chassis and frame. And 98 percent of the frame is made from high-strength steel, with aluminum making up a small amount in parts like the transmission crossmember and engine mounts. The Ram 1500 also gets an aluminum hood and tailgate. The weight may be down, but the 2019 Ram 1500 is longer and wider than before. The bed height, too, has increased. Visually, it's difficult to notice the increased size. The overall design is an evolution of what Ram has offered for decades. The most obvious change is the lack of a crosshair grille, a staple since 1994. The new "RAM" grille started as an option but now carries over to every single model. It's not going to be popular with everyone, but we're sure Mopar or some other parts supplier can fill your t-shaped void. The drop fender that also debuted on the '94 Ram has been lifted, giving the front a far more upright face. There are two different headlight designs, depending on the trim and options. The top-tier LED units are wide and slim, while the standard lighting looks similar to what we have now. The front bumper can be chrome or paint, while the chrome accents carry around to parts like the new 1500 badge on the hood. Tow hooks are lower and further apart than before, while the parking sensors have been better integrated into the design. Like the headlights, the taillights are an evolution of the current shape. Both halogen and LED units are available. The full-width steel rear bumper can be had in either chrome or body color. As for paint, there are 12 colors in total, with three two-tone variants. If that's not enough variety, there are 16 new (six-lug!) wheel designs to choose from, ranging from 18 to 22 inches. View 160 Photos Inside, the 2019 Ram 1500 is more refined and practical than ever before.

Autoblog's Editors' Picks: Our complete list of the best new vehicles

It's not easy to earn an “EditorsÂ’ Picks” at Autoblog as part of the rating and review process that every new vehicle goes through. Our editors have been at it a long time, which means weÂ’ve driven and reviewed virtually every new car you can go buy on the dealer lot. There are disagreements, of course, and all vehicles have their strengths and weaknesses, but this list features what we think are the best new vehicles chosen by Autoblog editors. We started this formal review process back in 2018, so there's quite of few of them now. So what does it mean to be an EditorsÂ’ Pick? In short, it means itÂ’s a car that we can highly recommend purchasing. There may be one, multiple, or even zero vehicles in any given segment that we give the green light to. What really matters is that itÂ’s a vehicle that weÂ’d tell a friend or family member to go buy if theyÂ’re considering it, because itÂ’s a very good car. The best way to use this list is is with the navigation links below. Click on a segment, and you'll quickly arrive at the top rated pickup truck or SUV, for example. Use the back button to return to these links and search in another segment, like sedans. If youÂ’ve been keeping up with our monthly series of the latest vehicles to earn EditorsÂ’ Pick status, youÂ’re likely going to be familiar with this list already. If not, welcome to the complete list that weÂ’ll be keeping updated as vehicles enter (and others perhaps exit) the good graces of our editorial team. We rate a new car — giving it a numerical score out of 10 — every time thereÂ’s a significant refresh or if it happens to be an all-new model. Any given vehicle may be impressive on a first drive, but we wait until itÂ’s in the hands of our editors to put it through the same type of testing as every other vehicle that rolls through our test fleet before giving it the EditorsÂ’ Pick badge. This ensures consistency and allows more voices to be heard on each individual model. And just so you donÂ’t think weÂ’ve skipped trims or variants of a model, we hand out the EditorsÂ’ Pick based on the overarching model to keep things consistent. So, when you read that the 3 Series is an EditorsÂ’ Pick, yes, that includes the 330i to the M3 and all the variants in between. If thereÂ’s a particular version of that car we vehemently disagree with, we make sure to call that out.
