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

2015 Chrysler 300 First Drive [w/video]

When Chrysler last updated its 300 in 2011, the fullsize sedan market was a very different place than it is today. Ford's redesigned Taurus was in showrooms, sure, but segment stalwarts like the Toyota Avalon and Chevrolet Impala were languishing at the tail end of their model cycles. And still, the second-generation 300 (not counting the "letter series" cars from the 1950s and '60s, of course) failed to recapitulate the booming success of the model reboot in 2004. Something in the combination of the down economy, higher gas prices and great product from front-wheel-drive entries in the class kept the 300 from the six-digit sales numbers it saw in the early 2000s. For the 2015 model year, Chrysler hopes that a more clearly defined purpose for its big sedan, combined with liberal dipping into the corporate tech toy box, will rekindle buyer interest. Considering the mild characters and front-driver dynamics of its mainstream competition, the promise of V8 power and rear-wheel drive should at least turn the heads of those looking for a car with a little edge. I grabbed the keys of the edgiest of the bunch, the sport-intended 300S, and found a big sedan that gives away some practicality to the rest of its segment mates. The trade-off for the dip in pragmatism is an uptick and driving fun and attitude that should make all the difference for the right buyer. Even though the hard-to-miss face of the 300 has come in for another nip and tuck, that attitude is still clearly on display, too. The grille of the 300 is some 33-percent larger than the outgoing model, though it's still far less brutal than the throwback styling of the 2005 "Baby Bentley" car, at least to my eyes. The cheese grater insert is metallic in most trims of the 300, though the 300S you see in my photo set gets the meaner blacked-out treatment. A quick scroll through our gallery will show you that the rest of the 300 has been similarly changed but not reinvented. Light clusters front and rear are revised, the rear clip has been re-forged with less busy styling, and the whole car has been de-chromed to a large extent (this 300S is wearing the least blingy outfit of the bunch). That rear spoiler is S-model specific. I held the existing 300 interior in fairly high regard, and this new car improves on that base.

Fiat Chrysler and Renault are in advanced partnership talks

Fiat Chrysler Automobiles and Renault are in advanced discussions about a possible alliance, according to a report from the Financial Times citing an anonymous "person familiar with the matter." The news isn't particularly surprising, as FCA has been a constant subject of merger and alliance talks for as long as many of us can remember. We've reported on a potential tie-up between these two automakers several times, as far back as 2008 and as recently as two months ago. FCA CEO Mike Manley has mentioned the company's openness to merging with another automaker. At the Geneva Motor Show a few months back, he said, "We have a strong independent future, but if there is a partnership, a relationship or a merger which strengthens that future, I will look at that." It's no secret that FCA is much stronger in the United States than it is in Europe. For its part, Renault has basically zero presence in the United States. A partnership or potential alliance between the two could shore up each automaker's weak spots and allow the group to split investment money into new technologies, including electric vehicles and autonomy. Of course, Renault is already tied up with Nissan and Mitsubishi, but that partnership has been a little tattered since the arrest of former Nissan and Renault CEO Carlos Ghosn on charges of financial misconduct in Japan. And in addition to Renault, FCA is understood to have discussed various partnership strategies with the PSA Peugeot Citroen group. What a final agreement – if there's any agreement at all – could look like between the two global automakers remains to be seen, and the report from Financial Times cautions that many different options for FCA and Renault are currently on the table. In other words, stay tuned.
