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

2023 Alfa Romeo Giulia and Stelvio tweaked outside and in

Another Stellantis brand has hopped on the streamlining craze, this time Alfa Romeo. The Italians from Turin dropped info on what's coming to the 2023 Giulia sedan and Stelvio crossover for international markets, the best bits likely destined for our market as well. After introducing new brand hallmarks on the Tonale, the Giulia and Stelvio adopt the revised Trilobo grille and three-section full-LED headlights. You'll need look closely to see the grille differences, but there's a touch more depth and sculpting around the edges. The headlight changes are easier to spot, the "3+3" inspiration coming from the SZ and Brera, which predate the Tonale. The headlights also come with automatic high beams. Other shores that can have fancy lights get the Adaptive Matrix high beams that automatically adjust beam contours so as not to blind oncoming traffic. Yes, the National Highway Traffic Safety Administration cleared the mechanics of such lights for use in the U.S. in February of this year, but U.S. laws stipulate a lower maximum brightness than allowed in other markets. We'll see if the matrix system makes it here. The taillights don't appear to have changed, their covers have. The Giulia gets transparent glass taillight covers, the Stelvio gets smoked glass. There could be some illumination tricks front and back, too. We're used to seeing sequential turn signals in back, spy shots have shown a sequential turn signal pattern in the headlights, and Alfa says there's a "'Welcome and Goodbye' device that turns on every time the driver closes or opens the car."  Every trim features a 12.3-inch digital instrument panel that comes with three themes. The Heritage theme recalls the analogue gauges on vintage Alfas, with some upside down numbers on the analogue-looking speedo, a minimalist tachometer and a digital facsimile of the old school odometer with rolling numbers. Evolved "represents the future of Alfa Romeo design," placing most information in the center, the circular areas at the edges containing sweeping needles for the speedo and tach, but no numbers in the 'dials.' Relaxed puts nearly everything in the center, putting vitals like fuel level and oil temperature at the sides. Trim levels will be reorganized into two primary levels and two options levels. The basic tiers are Super, the entry-level, and Ti.

Updated Alfa Romeo Tonale possibly caught camo-free during design clinic

Amateur spy shots taken during what looks like a design clinic held behind closed doors have shed light on how Alfa Romeo's Tonale concept is evolving on its way to production. They suggest the design study presented during the 2019 Geneva auto show wasn't as close to done as many thought. The photos were posted on an Italian enthusiast forum and quickly taken down, but they were saved and published by an Instagram user named CocheSpias. Alfa Romeo did not distribute them on its official channels, so we can't be 100 percent certain about their authenticity. Assuming they're the real deal, they reveal the Tonale has mellowed out considerably since it first showed its nose in Geneva. The headlights are bigger in nearly every direction, they're less bionic-looking, and they're separated from the grille by smaller, recessed air vents. It's a look that's very loosely reminiscent of some of the company's classic models, like the Giulia Sprint GT. Stylists also re-shaped the hood.           View this post on Instagram                   Aqui os dejamos unas fotos de una de las maquetas pre-produccion del futuro SUV de Alfa Romeo.

The rear door handles remain integrated into the C-pillar to give the Tonale a two-door look, a styling cue also seen on the Giulietta sold in Europe. The rear lights are bigger, though they're still connected by a light bar. The emblem on the hatch confirms Alfa Romeo hasn't changed its mind about the crossover's name. The user who posted the photos from the design clinic explained he wasn't given permission to upload images of the interior. He reported the Tonale's steering wheel looks a lot like the Giulia's, and the dashboard receives the same blend of round and rectangular air vents. The infotainment system's touchscreen is propped up on the dashboard rather than neatly integrated into the center stack, a layout which makes it easier to change during a mid-cycle update, or as tech advances. Mechanical specifications remain under wraps. Alfa didn't have much to say about the concept, either, but we know it used a gasoline-electric plug-in hybrid drivetrain.
