VW decides against active-cooling system for e-Golf lithium battery

When the 2015 VW e-Golf was introduced at the LA Auto Show last year, VW said it would come with a water-cooled battery. During the Detroit Auto Show, when the car was trotted out again, VW released a new press release that stripped out the "water-cooled" language, but this change went unnoticed. During a recent VW event in Germany, a friend from Green Car Reports realized that the battery on display did not seem to have any water-cooling mechanisms. That set us off on a bit of a sleuthing and we have now learned that VW is not going to include any active cooling in the upcoming e-Golf. In fact, the company is entirely confident that this car - because of what it's designed to do - doesn't need it. "The need for a cooling system wasn't there" - VW's Darryll Harrison VW has been working on an electrified Golf for ages now, and so changes to the plan are to be expected. But battery cooling is vitally important not just to keep the car operating properly but because when things get too hot, there can be serious public relations problems. Nissan began testing a new battery chemistry for the Leaf in 2013 after an uproar from warm-weather EV drivers in Arizona who were experiencing worse-than-expected battery performance. The Leaf has always used an air-cooled battery, which is another way to say that there is no active cooling system (more details here). Tesla CEO Elon Musk once said this approach is "primitive." So, why is VW following the same path? We asked Darryll Harrison, VW US's manager of brand public relations west, for more information, and he told AutoblogGreen that VW engineers discovered through a lot of testing of the Golf Mk6 EV prototypes, that battery performance was not impacted by temperatures when using the right battery chemistry. That chemistry, it turns out, is lithium nickel manganese cobalt oxide (NMC) in cells from Panasonic. These cells had "the lowest self-warming tendency and the lowest memory effect of all cells tested," Harrison said. He added that VW engineers tested the NMC cells in places like Death Valley and Arizona and found they didn't warm very quickly either through operation, charging (including during fast charging) or through high ambient temps. "The need for a cooling system wasn't there," Harrison said.

This week in EVs: Electric Jeeps, Chevy Equinox, reborn VW bus

There's going to be tons of car news next week as the Detroit Auto Show makes its return after 48 years. OK, so the pandemic and the show's shifting calendar only made it feel like 48 years, but January 2019 was still a long time ago. As we await that wave of headlines, let's look back at the substantial week that already was, specifically in terms of the electric car news that broke. Electric Jeep Recon and Wagoneer S blaze trail to brand's EV future Jeep declared Thursday to be 4xe Day as it revealed loads of previously unknown information about its future electrification efforts. The biggest surprise was the extremely cool and 100% electric Jeep Recon. Although it looks like a Wrangler, it's absolutely not a Wrangler replacement, and is indeed quite different for reasons besides its powertrain (independent front and rear suspension, fully enclosed fenders, fixed roof). As the photos attest, though, you'll be able to remove the doors and rear-quarter windows just like a Wrangler. And again, it's electric. Expect the Recon to be one of the most eagerly anticipated new vehicles over the next couple of years. Yes, years, plural. Production will start in 2024 with reservations accepted starting early next year. Jeep Recon View 5 Photos   There was then the Wagoneer S. Despite the name, it isn't a sportier Wagoneer variant or even an electric Wagoneer. In fact, the name is temporary according to chief designer Ralph Gilles. This sleek SUV, which sure looks like Jeep's attempt at a Range Rover Vilar (not a bad thing), will apparently have a 600-horsepower electric powertrain. It too will be produced in North America starting in 2024 with reservations starting early next year. Jeep Wagoneer S View 4 Photos   There actually WILL be an electrified Wagoneer, however: the Grand Wagoneer 4xe PHEV. That's good since the Grand Wagoneer gets pretty atrocious fuel economy. Details were light regarding specs, but we did get a half-decent photo. Finally, the first of these electrified Jeeps to launch will be the Avenger. Yes, Chrysler/Stellantis is dusting off an old Dodge name for a Jeep. That Dodge in question wasn't sold in Europe, though (good for them), which is important since the Jeep Avenger will only be sold on the other side of the pond. It's mechanically based on the same platform as several French Stellantis EV SUVs, and only goes 249 miles on the far more generous European WLTP test cycle.

VW rearranges leadership as brand focuses on electrification

The Volkswagen overhaul continues into next year with a raft of new executive appointments that CEO Mattias Muller says will enable "Faster decision-making and more efficient action." One of the headline moves is Porsche head of design Michael Mauer taking over VW Group design, succeeding Walter de Silva who retired in early November after running the Group's styling bureau since 2007. Among the sheetmetal on Mauer's resume are the Mercedes SLK and SL from the late nineties, the 2007 Porsche Cayenne, the Panamera, and, most recently, the 918 Spyder. He will retain his current role at Porsche in addition to the new responsibilities. Here's hoping some of the excitement seen in the 918 filters its way down to VW's recently mundane offerings. Dr. Ulrich Eichhorn was head of Group R&D from 2000 to 2003, then went to Bentley, then left the company for the German Association of the Automotive Industry in 2012. He has been lured back to his old role in charge of Group R&D, taking over the shoes recently worn by Dr. Ulrich Hackenberg, who resigned in early December while still suspended over his involvement in the diesel emissions fiasco. Ralf-Gerhard Willner takes over Group Product and Modular Toolkit Strategy, after leading development vehicle concept divisions at Audi and VW, and being technical director at Italdesign Giugiaro. He will play a huge role as VW evolves and expands its current platform strategy to include purpose-built electric cars and flat batteries. All those bottoms will be in chairs in Q1 of next year. The number of department heads that report directly to Muller has also been cut, giving Muller more time to focus on "overarching issues of the future." VW says that primary among them will be technology issues from EVs to digital integration. Back in October the company hired Thomas Sedran away from Opel as a lead strategist, his job being to figure out how each of those technical departments and the Group's brands navigate the marketplace and those "issues" from now until 2025. The press release below has more.
