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

Is Ram working on an HD Hellcat pickup truck?

Ram already offers an off-road-oriented Power Wagon pickup truck based on its heavy-duty 2500 chassis, and that's no slouch with a 410-horsepower, 6.4-liter Hemi V8. But add a 707-hp Hellcat to the mix and our interest goes through the roof. But is that what we're actually looking at in the spy photos above? Even a cursory glance at the shots proves these aren't ordinary Ram 2500 trucks. The most obvious visual hint is the big ram-air hood, but we also see a definite lift kit and heavy-duty suspension components underneath. The removal of the front and rear bumpers indicates that these trucks have good approach and departure angles, but it could also mean that whatever is underhood needs major airflow. Notice, too, that the two trucks seen here aren't traditional Crew Cab models, which is how the Power Wagon comes standard. Instead, there's a single cab and a massive Mega Cab sitting side by side. Is Ram going to unleash two new Power Wagon variants? Seems possible. It's really not possible to talk about a potential Ram HD Hellcat pickup truck without mentioning the Ford Raptor. The Blue Oval's SVT division has created one heck of a factory off-road monster, and it's set to get even better for the 2017 model year with an EcoBoost engine and four full-size doors. How could Ram, one of Ford's biggest truck competitors, answer Ford's latest assault? How about a Hellcat! Based on FCA's desire to put a Hellcat engine into anything that can hold it, it wouldn't be shocking to see an overpowered Ram model. And if that does happen, the Power Wagon platform is a great place to start. We don't know if that's what we're looking at, or if these trucks are test beds for future parts for the Mopar catalog, but either way we like what we see.

How to update and secure a vulnerable Chrysler Uconnect system

If you own one of the 1.4 million vehicles affected by the recent Chrysler software recall, you may want to watch this video. In it, we explain how to get the latest infotainment software loaded onto the 8.4-inch Uconnect system. The recall was a response to the findings of researchers who were able to hack into and remotely control a 2014 Jeep Cherokee through its cellular connection. Although Fiat Chrysler has worked with Sprint to plug most of the holes on the carrier side, there are still some vulnerabilities that only this latest software version can patch. Owners have three options to get the update: download it now, wait for a USB stick in the mail, or take the vehicle to an FCA dealer. Chrysler will be sending USB sticks loaded with the software update to customers. Anyone with an internet connection and a USB stick of their own with at least 4 GB capacity can speed things up by downloading the patch from the Uconnect website. We cover that process from start to finish in the video, with the final portion still applicable to those using the FCA-supplied USB stick. If after watching this you still don't want to tackle the patch yourself, you can take your vehicle to the dealer to have it done. Also note that this process is the same for all Uconnect updates, not just the one patching the exploits. Our demonstrator vehicle is a 2015 Ram 1500 pickup. The procedure should be very similar on other products with the 8.4-inch Uconnect system, with only the location of the USB port varying. Once you have the USB stick with the software on it – either after having downloaded it yourself or receiving it in the mail from Chrysler – the installation process is relatively simple. It takes about 15 minutes to perform the update; we edited out the wait in the video. To check whether or not your car's 8.4-inch Uconnect system is running the latest software, go to System Information on the touch screen's Settings page and look at Software Version. The update related to the recall is version 15.17.5. Related Video: Recalls Chrysler Dodge Jeep RAM Safety Technology Infotainment Videos Original Video hacking
