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

Alfa Romeo Giulia Luggage Test: How big is the trunk?

The Alfa Romeo Giulia is a brilliant little sport sedan to drive, a true delight every time you get a chance to jump behind the wheel. But what might it be like on a road trip? Well, it's a sedan, so obviously you can bring some friends along, but the back seat certainly isn't the largest out there and neither is the trunk. To be clear, this isn't necessarily a bad thing. A bigger Giulia would probably be a worse Giulia to drive. One simply needs to be aware of the trade-off. According to the specs, the Giulia's trunk measures ... um, actually, they're not listed anywhere on the specs provided on the Stellantis media website. For any Giulia from 2024 to 2017. Let's go ahead and check the consumer website then. Wow, nothing there, either. OK then, thank goodness for the luggage test, then. Let's snap to it! OK, so here is the trunk. It is not big, but how might it compare to other sport sedans I've tested, including the Genesis G70 (10.5 cubic-feet), Cadillac CT4 (10.9) and BMW 3 Series (depends on model)? Let's find out.  As in every luggage test I do, I use two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D). There are two options here. On the left, the fancy bag on top of one of the medium black roller bags, plus the biggest bag (gray) and smallest roller (blue). Alternatively, I could fit the small blue and its bigger check-in sibling, plus the two medium-sized bags -- but the small blue one would be a big squished.  Obviously, as you can see here, there's lots of left over space. There's also two bags left out regardless of configuration. Why? There's just not a lot of height in this trunk, and there are things hanging down that hamper it further. Shown above are speakers can might catch on something, plus the fat structural crossmember running above the fold-down seat pass-through that prevents bags from sliding all the way back. The biggest hindrance, though, are these large seat pass-through pulls on the left and right side of the trunk. They got in the way when trying to stack bags on their bellies atop each other.
