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

Stellantis previews 4 electric platforms: Here's how they'll be used

Stellantis EV Day is hitting hard and fast this morning, with big news coming from Dodge and Ram and Jeep and the rest. But to support those brand transformations, a core initiative within Stellantis will help it become a leader in electrification. To do that, the group is developing platforms and technologies with cross-shared components and systems. This starts with four flexible BEV platforms: STLA Small, STLA Medium, STLA Large and STLA Frame. As for targeted numbers, they’re lofty: By 2024, Stellantis aims for over 500 miles of range, 0-62 mph in 2 seconds and charging 200 miles of range in 10 minutes. The four platforms will offer battery capacities from 37 kWh to more than 200 kWh. More specifically, STLA Small will offer 37-82 kWh and up to 300 miles of range. STLA Medium will have 87-104 kWh and up to 440 miles. STLA Large will provide 101-118 kWh and up to 500 miles of range. The truck-focused STLA Frame will provide 159-200+ kWh and up to 500 miles of range (and will support an electric Ram 1500 pickup). Chrysler EV Front 34 View 8 Photos Stellantis has big plans for the STLA Large platform, and is currently developing eight vehicles for it in the next three to five years. Examples of possible vehicles shown include a midsize Ram truck and a Jeep off-roader that could fight against the likes of the Toyota 4Runner. Stellantis design boss Ralph Gilles could be seen in a presentation looking over a Chrysler electric crossover based on this platform. We also saw a Wagoneer badge teased momentarily. There was a rendered silhouette of a crossover that looked like it could compete with the Ford Mustang Mach-E. Gilles said the platform would allow Stellantis to “create a long-range luxury sedan, an all-conquering muscle car, a heart-of-the-market DUV, a heart-of-the-market SUV, a very capable Jeep off-roading white-space opportunity vehicle as well as a new mid-sized truck.” See for yourself in this video starting at the 90-minute mark. As for powertrains, Stellantis is developing three electric drive modules with a shared, scalable inverter, and other common components, as well as in-house software to control them. Those drive units will offer from 70 to 330 kW (94-402 horsepower). More specifically, one EDM will provide 70 kW, a second will provide 125-180 kW, while the most potent can produce 150-330 kW.

Peugeot E-Boxer seems like it would make a nice electric Ram ProMaster

Though electric cars, and especially pickup trucks, are the hot zero-emissions battlefield, there's another sector that's heating up: commercial vans. Startups such as Rivian and Bollinger have announced plans for vans, and Ford has shown a prototype of an electric Transit. It seems Stellantis is slightly ahead of the curve, though, as it has revealed details of its electric vans with the Peugeot E-Boxer. And the reason you should care is that the E-Boxer and gas-powered Boxer are nearly identical to the American-market Ram ProMaster and Italian Fiat Ducato. Powering the E-Boxer is a single electric motor at the front. It's not particularly powerful with just 122 ponies, but it has a more respectable 192 pound-feet of torque. Top speed is limited to 68 mph, which would probably need to be raised if these vans were offered in the U.S. Supplying power is one of two available battery packs: The shorter models get a 37-kWh battery that is rated for 124 miles of range on the WLTP cycle; longer models get a 70-kWh battery rated by WLTP for 211 miles. Those numbers would likely be lower in American EPA testing. While the range isn't incredible, enormous range likely isn't as important for delivery vans that might operate locally. These vans also come with DC fast charging in case more range is needed quickly. Though not quick, the Peugeot E-Boxer doesn't sacrifice on practicality. No cargo space is sacrificed for the electric powertrain, so you can fit just as much into one as a similarly configured gas model. Payload capacity is comparable to the gas vans, even the V6 ProMaster, too, with a maximum of 4,167 pounds. This number does vary based on configuration, just like cargo space. Peugeot will offer it in four different lengths with three roof heights as well as chassis and cutaway cab models. So it's just as configurable as the regular version. With some adjustment to how quick the E-Boxer can go, it would seem like it could be offered in the U.S. and beat some competitors to the punch. It's all built on the existing Ram ProMaster platform that we get here. And electric power would seem appealing to businesses that need delivery vans: lower fuel and maintenance costs. Time will tell if Stellantis sees things the same way. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.
