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

5,600 Fiat 500e EVs recalled for buggy software

Fiat will be recalling some 5,600 of its all-electric 500e hatchbacks, all of which hail from model years 2013, 2014 and 2015. Weirdly, this recall is being caused by a March 2015 software update. According to The Detroit News, last month's update addressed the software in the Electric Vehicle Control Unit and Battery Pack Control Module "to implement improvements in charging system robustness, diagnostic capability and range estimation over life. In addition to the primary reasons for the software update, Limp Home Mode was included as part of battery pack software continuous improvement," FCA explained. "It was because of this software update that the software incompatibility occurred where the EVCU did not recognize the Limp Home Mode." Should your car go into limp mode, "incompatible software between Electric Vehicle Control Unit (EVCU) and Battery Pack Control Module (BPCM) may cause the electric propulsion system to fully shut down," according to the National Highway Traffic Safety Administration bulletin. So yes, the March software update can cause your EV to stall. Vehicles built between March 27, 2012 and November 1, 2014, which sounds like basically all 500es, are affected by the recall. Chrysler will begin notifying owners with recall operations to begin in the middle of next month. Scroll down for the official NHTSA bulletin. Related Video: Report Receipt Date: MAR 27, 2015 NHTSA Campaign Number: 15V179000 Component(s): ELECTRICAL SYSTEM Manufacturer: Chrysler (FCA US LLC) SUMMARY: Chrysler (FCA US LLC) is recalling certain model year 2013-2015 Fiat 500 EV vehicles manufactured March 27, 2012, to November 1, 2014. If the vehicle goes in to limp home mode, incompatible software between Electric Vehicle Control Unit (EVCU) and Battery Pack Control Module (BPCM) may cause the electric propulsion system to fully shut down. CONSEQUENCE: An electric propulsion system shut down will cause a stall-like condition, increasing the risk of a crash. REMEDY: Chrysler will notify owners, and dealers will update the vehicle software to ensure compatability between components, free of charge. The recall is expected to begin May 15, 2015. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is R15. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Fiat Doblo Cargo is an Italian Ram Promaster City

Meet the new Fiat Doblò Cargo, the Italian cousin of the recently debuted Ram ProMaster City. As part of the Fiat Professional line, we wouldn't count on seeing this one on US shores, but as Fiat Chrysler's compact cargo entry in Europe, expect to see plenty of the mini haulers across the pond following its debut at the Hanover Motor Show.
This isn't a full-tilt redesign for the Doblò Cargo, so much as it is a significant refresh that sees the compact cargo van adopt a new, more stylish front fascia, which borrows inspiration from the larger Ducato van, sold Stateside as the Ram ProMaster. While it's not terribly handsome, it is a major improvement on the awkward looks of the pre-facelift Doblò. Its links with the ProMaster City, meanwhile, are plain to see.
Unlike North America's ProMaster City, which runs on Chrysler's 2.4-liter, Tigershark four-cylinder, the Doblò Cargo is available with a pair of diesel engines; a 90-horsepower, 1.3-liter and a 105-hp, 1.6-liter. While those two mills are sure to be easy on fuel costs, they can be made even better thanks to an optional stop-start system. These so-called "EcoJet" engines can return up to 64 miles per gallon, according to Fiat.
