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.

Intel-Mobileye tech in 2M BMWs, VWs, Nissans will crowdsource maps for autonomy

Intel Chief Executive Brian Krzanich said on Monday 2 million vehicles from BMW, Nissan and Volkswagen would use its unit Mobileye's technology to crowdsource data for building maps that enable autonomous driving. The world's largest chipmaker bought Israeli firm Mobileye last year to compete with peers such as Qualcomm and Nvidia Corp and tap the fast-growing market of driverless cars, filled with a complex tangle of alliances. (VW, for example, is also working with Nvidia.) Krzanich was the keynote speaker at the Consumer Electronics Show. He said data from Mobileye's Road Experience Management software would gather data to build and update scalable high-definition maps. He also announced that Intel would be working with Ferrari on AI drones to cover Ferrari Challenge North America Series racing. The drones would provide video of the races, but ultimately they would provide drivers with data — video that would let them see their racing performance from overhead, but also telemetry information about, say, how they enter and exit a turn. Intel will also tie up with SAIC Motor Corp, which will use Mobileye technology to develop Level 3, 4 and 5 autonomous cars in China, the chipmaker said. Krzanich also said Intel had not received any information of customer data being compromised so far after the company confirmed last week that security issues reported by researchers in its widely used microprocessors could allow hackers to steal sensitive information from computers, phones and other devices. Security researchers had disclosed two security flaws exposing vulnerability of nearly every modern computing device containing chips from Intel, Advanced Micro Devices and ARM Holdings.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.
