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.

VW announces recall of 26,000 2014 models with 1.8T engines

Volkswagen has followed up on a stop-sale order from earlier this month, announcing a voluntarily recall of 26,400 vehicles that are powered by the brand's 1.8-liter, turbocharged four-cylinder engine. The new mill replaced the despised 2.5-liter five-cylinder in the Jetta, Passat, Beetle and Beetle Convertible last year. Weirdly, though, of the 26,452 units covered in the recall, only 1,655 are customer vehicles.
According to VW, the affected models were built between February 1 and April 6 of this year, and feature bad O-ring seals in the transmission oil cooler. Apparently, the faulty O-rings could cause a fluid leak, as they won't seal between the oil cooler and transmission. VW is blaming a material change from a supplier for the problem.
There have been no fires, injuries, accidents or fatalities relating to this issue, which VW will be fixing free of charge. Customers will need to report to dealers to have the O-rings replaced.

Volvo, Daimler, Traton join forces to build electric truck charging network

Volvo Group, Daimler Truck and Volkswagen's AG heavy-truck business the Traton Group announced on Monday a non-binding agreement to build a network of high-performance public charging stations for electric heavy-duty long-haul trucks and buses around Europe. The news was first reported by Reuters. The three major European automakers will invest ˆ500 million (~$593 million USD) to install and operate 1,700 charging points in strategic locations and close to highways. They intend to finalize the agreement by the end of this year and start operations next year, with the hopes of increasing the number of charge points significantly as the companies seek additional partners for the future joint venture. The venture is meant to be a catalyst to prepare for the European Union's goals of carbon-neutral freight transportation by 2050. One of the main deterrents for both individuals and freight companies for switching to EVs has historically been a lack of charging infrastructure. By building that infrastructure, Volvo, Daimler and Traton can also expect to boost their own sales of electric trucks and buses. “It is the joint aim of EuropeÂ’s truck manufacturers to achieve climate neutrality by 2050," Martin Daum, CEO Daimler Truck, said in a statement.  "However, it is vital that building up the right infrastructure goes hand in hand with putting CO2-neutral trucks on the road. Together with Volvo Group and the Traton Group, we are therefore very excited to take this pioneering step to establish a high-performance charging network across Europe.” The partnership between Volvo and Daimler isn't unprecedented. In May, the two competitors teamed up to produce hydrogen fuel cells for long-haul trucks to lower development costs and boost production volumes. This latest venture is another signal that major companies are banding together to solve climate-related issues in the industry. European car industry association ACEA has called for up to 50,000 high-performance charging points by 2030. Traton CEO Matthias Gruendler told Reuters that roughly 10 billion euros would be needed to build out Europe's infrastructure to be fully electrified by 2050. According to a statement released by Volvo, this venture is also a call to action for others with a stake in the industry, like automakers or governments, to work together to ensure the rapid expansion needed to reach climate goals.
