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

Minivans could be key to Google-FCA self-driving partnership

Executives from Google and Fiat Chrysler Automobiles have held discussions about creating a technical partnership, the purpose of which would be to further development of self-driving vehicles, according to multiple reports. The two companies might make ideal partners. Google has been at the forefront of developing autonomous technology, and has publicly stated it'd seek partners to build vehicles. FCA, meanwhile, has not invested in self-driving research, and its CEO has been publicly offering the company up for acquisition for the last several years. Combined, they could make both the brains and the bodies of self-driving cars. "Public transit executives could be buying autonomous minivans rather than expensive buses." – Chris Urmson "A Google-FCA tie-up could simultaneously put both companies in the lead in this critical race," said Kelley Blue Book senior analyst Karl Brauer. "... FCA's efforts to merge with another automaker have failed, but if the automaker can join forces with Google, it could immediately change the dynamic. Every car company is trying to get into the tech space right now, because they all know their future depends on it." A Google spokesperson declined comment on the reports Thursday, and FCA did not return a request for comment. But Chris Urmson, director of Google's self-driving car project, may have inadvertently hinted at the partnership Wednesday when he detailed an interest in building autonomous minivans for public-transportation use. "Public transit executives could be buying autonomous minivans rather than expensive buses," Urmson said during a public meeting on autonomous regulations held by the National Highway Traffic Safety Administration in Palo Alto, California. "Federal standards determine what kinds of vehicles cities can use for transit. This needs attention." Minivans are different than the Lexus 450h and pod-like prototypes Google has used for autonomous testing so far. If Urmson is indeed interested in self-driving minivans that provide on-demand services for public transportation users, as he elaborated upon, there may be no more perfect partner than Chrysler, which pioneered the minivan segment three decades ago and recently reasserted its presence the minivan market with the new Pacifica, a completely redesigned vehicle. Ridding the urban environment of traffic-clogging buses might be one small slice of Google's broader plan for transforming cities and the imprint cars make upon them.

Our love of SUVs is killing people in the streets

Americans are fond of supersized fast-food meals and colossal convenience-store fountain drinks, even though they're clearly bad for our health and U.S. adults keep getting fatter. We also like large vehicles, and our love affair with SUVs is killing people in the streets. According to a recent investigation by the Detroit Free Press/USA Today, the increase in SUV sales over the past several years coincides with a sharp rise in pedestrian deaths in the U.S. — up 46 percent since 2009, with nearly 6,000 people killed in 2016 alone. With SUV sales surpassing sedans in 2014 and pickups and SUVs currently accounting for 60 percent of new vehicle sales, it's no wonder Ford announced in April plans to cease U.S. sales of almost all passenger cars. And this followed Fiat Chrysler's move to virtually an all-truck, -SUV and -crossover lineup. While the Freep/USA Today investigation found that the simultaneous surge in SUV sales and pedestrian deaths comes down to vehicle size, it also points to a lack of action on the part of the National Highway Traffic Safety Administration (NHTSA), even though it knew of the dangers SUVs pose to pedestrians. Also blamed are automakers dragging their feet on implementing active safety features. Using federal accident data, the Insurance Institute for Highway Safety (IIHS) determined that there was an 81 percent increase in single-vehicle pedestrian fatalities involving SUVs between 2009 and 2016. Freep/USA Today's analysis of the same data by counting vehicles that struck and killed pedestrians instead of the number of people killed showed a 69 percent increase in SUV involvement. As far back as 2001, researchers at Rowan University forecasted a rise in pedestrian deaths as Americans began switching to SUVs. "In the United States, passenger vehicles are shifting from a fleet populated primarily by cars to a fleet dominated by light trucks and vans," the researchers wrote, with light trucks comprising SUVs.
