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

EV cost burden pushing automakers to their limits, says Stellantis' CEO Tavares

DETROIT — Stellantis CEO Carlos Tavares said external pressure on automakers to quickly shift to electric vehicles potentially threatens jobs and vehicle quality as producers struggle with EVs' higher costs. Governments and investors want car manufacturers to speed up the transition to electric vehicles, but the costs are "beyond the limits" of what the auto industry can sustain, Tavares said in an interview at the Reuters Next conference released Wednesday. "What has been decided is to impose on the automotive industry electrification that brings 50% additional costs against a conventional vehicle," he said. "There is no way we can transfer 50% of additional costs to the final consumer because most parts of the middle class will not be able to pay." Automakers could charge higher prices and sell fewer cars, or accept lower profit margins, Tavares said. Those paths both lead to cutbacks. Union leaders in Europe and North America have warned tens of thousands of jobs could be lost. Automakers need time for testing and ensuring that new technology will work, Tavares said. Pushing to speed that process up "is just going to be counter productive. It will lead to quality problems. It will lead to all sorts of problems," he said. Tavares said Stellantis is aiming to avoid cuts by boosting productivity at a pace far faster than industry norm. "Over the next five years we have to digest 10% productivity a year ... in an industry which is used to delivering 2 to 3% productivity" improvement, he said. "The future will tell us who is going to be able to digest this, and who will fail," Tavares said. "We are putting the industry on the limits." Electric vehicle costs are expected to fall, and analysts project that battery electric vehicles and combustion vehicles could reach cost parity during the second half of this decade. Like other automakers that earn profits from combustion vehicles, Stellantis is under pressure from both establishment automakers such as GM, Ford, VW and Hyundai, as well as start-ups such as Tesla and Rivian. The latter electric vehicle companies are far smaller in terms of vehicle sales and employment. But investors have given Tesla and Rivian higher market valuations than the owner of the highly profitable Jeep and Ram brands. That investor pressure is compounded by government policies aimed at cutting greenhouse gas emissions. The European Union, California and other jurisdictions have set goals to end sales of combustion vehicles by 2035.

What's the deal with Chrysler demanding colleges crush their Vipers? [w/video]

Students and teachers at a Washington community college are up in arms following an order from Chrysler that it must destroy the pre-production Dodge Viper that was donated to the school's automotive technology program ten years ago.
The Viper in question is said to be the fourth off the production line, based on its VIN, and has had its emissions controls disabled, allowing its ten-cylinder engine to produce 600 horsepower, according to a report from Yahoo! Autos. As one of the first Vipers ever produced, the school's AT instructors claim it could be worth $250,000 in a museum, while a local news report purports that Jay Leno once tried to purchase the car, but the sale was prevented by Chrysler.
As pointed out by our friends at Autobytel, though, there are a lot of things in this story that don't quite add up. Immediately noticeable from the news report embedded below - which shows the car at South Puget Sound Community College - is that the car in question is not a 1992 model. When the Viper went on sale in 1992, it was only available as an RT/10 with a (flimsy) soft top, like the red car shown above. But the car featured in the report from KING5 News (inset image) is clearly a hardtop Viper GTS, which didn't enter production until 1996. And even if, as reported by a local newspaper, the hardtop featured is a prototype, it doesn't explain the lack of another iconic feature of the first Vipers - their distinctive side pipes. This kind of pokes holes in the school's argument that this is the fourth Viper to ever roll down the line. At best, this appears to be a pre-production Viper GTS.
