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

Chrysler Recalls Over 566,000 Trucks, SUVs

Fiat Chrysler is recalling more than 566,000 trucks and SUVs in two recalls for malfunctioning fuel heaters that can cause fires and a software glitch can disable the electronic stability control. The recalls bring the newly merged company's total for the year to 6.4 million vehicles worldwide and 5.1 million in the U.S. as it continues to struggle with reliability problems. It was not immediately clear whether those totals were annual records. On Tuesday, its longtime quality chief abruptly left after Fiat Chrysler performed poorly in Consumer Reports magazine's annual reliability rankings. The largest of two recalls announced Wednesday covers almost 382,000 Ram 2500 and 3500 pickups and Ram 4500 and 5500 chassis cabs from 2010 through 2014. In trucks with 6.7-Liter Cummins diesel engines, corrosion on a fuel heater terminal could cause overheating, fuel leaks and fires. Chrysler is not aware of any fires or injuries. Owners could be warned by an odor of diesel fuel. Customers will be notified by letters starting in December. Dealers will install upgraded terminals and fuel heater housings could be replaced. The second recall covers more than 184,000 Jeep Grand Cherokee and Dodge Durango SUVs from 2014. A debris cover over a circuit board in the steering column control module can disrupt communications and disable the stability control. The problem was discovered when dealers started getting reports from customers that electronic stability control warning lights were coming on. Fiat Chrysler says it knows of no crashes or injuries caused by the problem. Technicians will upgrade software to fix the SUVs, and customers will be notified in December. Fiat Chrysler has issued 33 global recalls and 27 in the U.S. so far this year. Doug Betts, its longtime quality chief, left the company to pursue other options after Consumer Reports' survey-based rankings this year showed four FiatChrysler brands at the bottom of its list. Dodge, Ram, Jeep and Fiat performed worst of 28 brands ranked by the magazine. Company spokesman Eric Mayne said Fiat Chrysler's recalls average fewer than 200,000 vehicles each, below the industry average of 301,000. That means the company is responding quickly to problems, he said, adding that eight of its 27 U.S. recalls were announced before the company received any consumer complaints. Chrysler is not alone with a high number of recalls so far this year.

The best cars we drove this year

Six hundred and fifty. That's roughly how many cars pass through the hands of Autoblog editors every year, from the vehicles we test here at home, to the cars we drive on new product launches, testing roundups, long-term cars, and so on. Of course, our individual numbers vary due to several reasons, but at the end of the day, our team's repertoire of automotive experience is indeed vast. But let's be honest, some cars certainly stand out more than others. So as the year's about to turn, and as we're readying brand-new daily cat calendars for our cubicles, our editors are all taking time to reflect on the machinery that made this year so special, with one simple, open-ended question as the guide – a question that we're asked quite frequently, from friends, family, colleagues, and more. "What's the best car you drove this year?" Lamborghini Huracan When I review the list of everything I drove in 2014, picking an absolute favorite becomes almost impossible. I mean, how does one delineate between the joy offered by cars as different as the Alfa Romeo 4C, Volkswagen Golf R, Mercedes-AMG GT S and even the humble-yet-wonderful Chevy Colorado? Okay fine, I'll just pick the Lamborghini. I drove the Lamborghini Huracan LP 610-4 on a racetrack, in the mountains, and along southern coast of Spain. It felt like the king of the car jungle in all of those places, sucking the eyeballs of observers nearly out of their heads as it drove by, and almost melting my brain with its cocktail of speed and grip and intense communication. It feels a little easy to say that the one new supercar I drove this year was also my favorite, but the fact is that the Huracan is one of the finest cars I've driven during my career, let alone 2014. Judge me if you must. – Seyth Miersma Senior Editor Rolls-Royce Wraith There are a couple of ways to look at the question, "What's the best car you drove this year?" In terms of what was so good I'd go out and buy one tomorrow, that'd be my all-time sweetheart, the Volkswagen GTI. Or if I'm just talking about sheer cool-factor, maybe something like the Galpin GTR1, BMW i8, or Mercedes-Benz G63 AMG. But instead, I'm going to write about the sheer opulence of being the best of the best. The hand-crafted, holier-than-thou, shut-your-mouth-when-I'm-talking-to-you supremacy. I'm picking the Rolls-Royce Wraith. I drove the Wraith for a week in April, and was really, really impressed. This car does everything, perfectly.
