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.

Fiat Chrysler dumped 40,000 unordered vehicles on dealers

In a move that echoes recent history, Fiat Chrysler has been making more cars and trucks than dealers in the U.S. are willing to accept, with Bloomberg reporting that at one point the automaker had built up a glut of around 40,000 unordered vehicles. That’s led some dealers to accuse FCA of reviving the dreaded “sales bank” accounting practice of obscuring inventory to improve the balance sheet. The company reportedly began building up its inventory of unordered cars this summer despite an industrywide slowdown in sales and an eagerness by some dealers to thin their inventories because rising interest rates are making it more expensive to hold unsold cars. The inventory build-up also coincided with Fiat ChryslerÂ’s efforts to find a merger partner, first with Renault, which fell through, then last monthÂ’s announcement that it will merge with FranceÂ’s PSA Group. FCA denies any such scheme and tells Bloomberg the rising inventory is down to a new predictive analytics system designed to better square supply with demand from dealers that is helping the company save money and narrow the numbers of unsold vehicles. The company recently agreed to pay a $40 million civil penalty to the U.S. Securities and Exchange Commission to settle a complaint that it paid dealers to report fake sales figures over a span of five years. While no one is suggesting that FCA is in dire financial straits — the company saw higher than expected earnings in the third quarter and record profits in North America — the practice has strong historical precedent by Chrysler, which built up bloated inventories in the run-up to its two federal bailouts, in 1980 and 2009. It was also common at GM and Ford during the 2000s, when all three Detroit automakers struggled with excess manufacturing capacity and plummeting sales in the lead-up to the Great Recession. Back in 2012, CFO Magazine wrote about a report that explained automakersÂ’ rationale for the practice and how it works: Say fixed costs for a given factory are $100, and that the factory can make 50 cars. Consumers, however, demand only 10. Under absorption costing, if the company makes all 50 cars, its cost-per-car is $2. If it makes only up to demand, or 10 cars, the cost-per-car is $10. Although each car adds variable costs for steel and other parts, if those costs are low, the company still has an incentive to make more cars to keep the cost-per-car down.
