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

FCA to recall 318,000 vehicles for faulty backup camera software

An array of 2019 and 2020 FCA vehicles are being recalled over faulty backup camera software that doesn’t meet federal regulations. According to recall documents, the backup camera may not turn off “until a drive cycle ends.” ThatÂ’s far longer than the 10-second linger time allowed by the rules, so FCA has to recall all of the vehicles to implement a fix. WeÂ’ve listed all of the vehicles involved below. 2020 Jeep Gladiator 2020 Jeep Cherokee 2019-2020 Ram 1500 2019-2020 Ram 2500  2019-2020 Ram 3500 2019-2020 Chrysler Pacifica 2019-2020 Dodge Durango 2019-2020 Jeep Grand Cherokee 2019-2020 Jeep Wrangler 2019-2020 Jeep Renegade 2019 Dodge Challenger ItÂ’s an extensive list encompassing a huge chunk of FCAÂ’s lineup in the United States. In total, FCA is recalling 318,537 vehicles. They must be equipped with the 8.4-inch or 12-inch infotainment system for the problem to present itself. FCA expects the recall to start on May 22 this year and will begin to notify owners soon. To fix the vehicles that may be affected, FCA plans to update the infotainment system at the dealer or over-the-air. If youÂ’ve noticed a screen thatÂ’s sluggish to relinquish its hold on the backup camera feed (or maybe never does), then you have this recall to look forward to. Update: FCA has provided additional information about the repair methodology. Customers will be able to receive an update over the air or have their cars updated at the dealership. Customers will begin receiving notifications this month. Related video: Recalls Chrysler Dodge Jeep Crossover Minivan/Van SUV

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.
