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

Google's deal with FCA is the 'first phase' of partnership

Google and Fiat Chrysler Automobiles confirmed a partnership Tuesday in which the two companies will collaborate on creating autonomous minivans. The two companies will work together to build and test approximately 100 Chrysler Pacifica hybrid minivans, and they first of the bunch could hit the road by the end of the year. This marks the first time Google has worked with a traditional automaker in designing a self-driving car since the start of its autonomous project in 2009. "FCA will design the minivans so it's easy for us to install our self-driving systems, including the computers that hold our self-driving software and the sensors that enable our software to see what's on the road around the vehicle," Google said in a written statement. "The minivan design also gives us an opportunity to test a larger vehicle that could be easier for passengers to enter and exit, particularly with features like hands-free sliding doors." "Those of us in the tech industry recognize how hard it is to build cars." – Jennifer Haroon. That could be particularly important if Google and FCA intend to launch the autonomous minivans as a competitor to traditional public transportation options. Chris Urmson, the director of Google's self-driving car project, indicated that may be a potential business model during a public meeting on autonomous operations last week. "Public transit executives could be buying autonomous minivans rather than expensive buses," he said. "Federal standards determine what kinds of vehicles cities can use for transit. This needs attention." In the Pacifica, Google's engineers get an all-new minivan. Chrysler showcased the vehicle for the first time in January at the North American International Auto Show in Detroit, and sales of the non-hybrid versions of the vans went on sale last month. FCA CEO Sergio Marchionne says further collaboration between his company and Google is possible. "This first phase of the operation is very targeted. It's designed to take Google technology into the minivan. It's very, very focused," he said, according to Automotive News. The collaboration won't be Google's first experience with hybrids. The Lexus RX 450h SUV is one of the two cars in its current test fleet, which consists of approximately 70 vehicles. With roughly 100 autonomous minivans slated to be part of the collaboration, Google's test fleet will more than double.

Consumer Reports says these are the worst new cars of 2014

Consumer Reports has announced its annual list of worst vehicles, a cringe-inducing contrast to its list of top vehicles. Ignominiously leading the way in 2014 is Chrysler, which has a staggering seven models listed.
Jeep nearly sweeps the small SUV segment by itself, with its Compass, Patriot and 2.4-liter version of the new Cherokee, while the only midsize sedans listed by CR were the Chrysler 200 and Dodge Avenger. The new Dodge Dart and the Dodge Journey round out CR's condemnation of Chrysler.
Ford is taking heat as well, with the Taurus, Edge and their counterparts from Lincoln all listed as the worst vehicles in their respective segments. Toyota doesn't fare much better, with its Lexus IS, Scion iQ and tC also making the list.
