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

Chevy Bolt EV, Chrysler Pacifica, Honda Ridgeline take 2017 NACTOY prizes

Every year the 2017 North American International Auto Show kicks off with the North American Car of the Year Awards. We say "awards" after all those mentions of our home continent because it's not just cars. This year, in fact, the awards spread out to three separate honors: Car, Truck, and Utility. And without further ado, here are the winners. The 2017 Chevrolet Bolt EV is the Car of the Year, the Honda Ridgeline is the Truck of the Year, and the Chrysler Pacifica is the Utility of the Year. Honda's win is perhaps the biggest surprise, upsetting favorite the Ford F Super Duty for the win. The second-generation Ridgeline rides on a unibody platform and is offered in front- or all-wheel-drive, which is unconventional for a pickup. But the layout also offers a cargo bed with an in-floor trunk and solid fuel economy figures of 19 city, 26 highway in its most-efficient form. The Chevy Bolt EV, however, was probably the easiest winner to predict. Its 238-mile range and sub-$30,000 starting price after tax credits make it a breakthrough in the landscape of electric vehicles. With the Chrysler Pacifica available in a plug-in hybrid form, this year's award illustrates the industry's shift towards efficiency and electrification. And with Ford's recent announcement on future EVs, it might not be long will it be until we see a hybrid truck on the award stage as well.Related Video:

Marchionne says the Chrysler 200 and Dodge Dart were terrible investments for FCA

In a press conference during the Detroit Auto Show, Sergio Marchionne was quite candid about why the Chrysler 200 and Dodge Dart were discontinued altogether without replacement. He essentially said they weren't worth the trouble. "I can tell you right now that both the Chrysler 200 and the Dodge Dart, as great products as they were, were the least financially rewarding enterprises that we've carried out inside FCA in the last eight years," Marchionne said. "I don't know one investment that was as bad as these two were." Marchionne was responding to a question about whether he felt the company's shift toward trucks and SUVs and sacrifice in sedan development was shortsighted. Marchionne said he felt that the market would likely continue to be strong for trucks and SUVs, and that the sedan market requires enormous investment that might not pay off. He used the 200 and Dart as examples. When we tried out the 200 and the Dart, we had mixed feelings. We enjoyed the 200's potent V6, pleasant interior, and solid handling. However, it was lacking in space (especially in the rear seat area), and doesn't drive any better than the top vehicles in the midsize sedan class. As for the Dart, it was fairly roomy, and had great infotainment thanks to Uconnect, but lackluster handling and a surprising amount of weight left it only average. With that in mind, it's probably not a bad idea to get rid of the 200 and Dart. The sedan segment is shrinking, and FCA can only afford to invest in areas where it can be a class-leader.
