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

Fiat Chrysler to pay $800M in Jeep, Ram emissions cheating case

WASHINGTON — Fiat Chrysler Automobiles NV has agreed to a settlement worth about $800 million to resolve claims from the U.S. Justice Department and state of California that it used illegal software that produced false results on diesel-emissions tests, but still faces an ongoing criminal probe. The hefty penalty is the latest fallout from the U.S. government's stepped-up enforcement of vehicle emissions rules after Volkswagen AG admitted in September 2015 to intentionally evading emissions rules. The Fiat Chrysler settlement includes $311 million in total civil penalties to U.S. and California regulators, up to $280 million to resolve claims from diesel owners, and extended warranties worth $105 million. It covers 104,000 Fiat Chrysler 2014-16 Ram 1500 and Jeep Grand Cherokee diesels, the Justice Department said. Regulators said Fiat Chrysler used "defeat devices" to cheat emissions tests in real-world driving. Fiat Chrysler said in a statement that "the settlements do not change the Company's position that it did not engage in any deliberate scheme to install defeat devices to cheat emissions tests." The company did not admit liability. "You wouldn't pay $311 million total dollars to the federal government in civil penalties if there were not a serious problem," U.S. assistant attorney general Jeff Clark told a news conference. The settlement also includes $72.5 million for state civil penalties, and $33.5 million in payments to California to offset excess emissions and consumer claims. German auto supplier Robert Bosch GmbH, which provided the emissions control software for the vehicles, also agreed to pay $27.5 million to resolve claims from diesel owners. Owners will receive an average of $2,800 to obtain software updates as part of the emissions recall, Fiat Chrysler said. Elizabeth Cabraser, a lawyer for the owners, said the "substantial cash compensation" will ensure that consumers get the recall fix. Bosch, which also provided diesel emissions software to Volkswagen, also agreed to pay $103.5 million to settle claims with 47 U.S. states that said the supplier "enabled" the cheating and should have known its customers would use the software improperly, the New York Attorney General's Office said.

Ram 1500 TRX too tame for you? Hennessey cranks its Hemi V8 to 1,012 horsepower

Ram captured the top spot on the horsepower podium when it released the Hellcat-powered 1500 TRX in 2020. The truck's 702-horsepower output places it comfortably ahead of the Ford F-150 Raptor, at least for now, but American tuner Hennessey saw plenty of room for improvement. It added over 300 horses to the TRX's cavalry. Hennessey is a master in V8-ology, so it was only a matter of time before it injected more power into the TRX. It announced two models named Mammoth 900 and Mammoth 1000, respectively, and each number vaguely corresponds to the V8's new output. The 900's 6.2-liter produces 912 horsepower and 873 pound-feet of torque, increases of 210 and 223, respectively, compared to the standard TRX. Hennessey achieved these figures by upgrading the supercharger pulleys and making relatively basic changes to the intake and exhaust systems. Stepping up to the 1000 unlocks 1,012 horsepower and 969 pound-feet of torque, numbers that give the 6,300-plus-pound truck the uncanny ability to reach 60 mph from a stop in 3.2 seconds. It flies through the quarter mile in 11.4 seconds at 120 mph. Building a pickup with supercar-like acceleration required installing a bigger, 2.65-liter supercharger, adding high-flow fuel injectors, and recalibrating the ECU. Intake and exhaust modifications are on the menu, too. Surprisingly, it doesn't sound like Hennessey made significant internal changes to the engine or to the transmission, which suggests the standard components can handle a massive amount of power. Context is useful here. Released in 2013, the fifth and final generation of the Dodge-turned-SRT-turned-Dodge again Viper took 3.3 seconds to sprint from zero to 60 mph, and it logged an 11.5-second quarter-mile time. Previewed in a computer-generated sketch, the Mammoth 1000 (shown above) also receives 20-inch wheels wrapped by 35-inch off-road tires, a 2.5-inch suspension lift, custom bumpers on both ends, extra LEDs up front, electronic fold-out steps, plus an array of model-specific emblems. Inside, Hennessey added a numbered plaque. 200 units of the Mammoth 1000 will be available for the 2021 model year, and pricing starts at $135,350 including the cost of the donor truck (which carries a base price of $71,790) and a warranty valid for two years or 24,000 miles. Put another way, you get 30.6% more power than stock for about 40% more money.
