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.

Coronavirus prompts VW to stop production throughout Europe

FRANKFURT — Volkswagen Group, the world's biggest carmaker, is suspending production at factories across Europe as the coronavirus pandemic hits sales and disrupts supply chains, the company said on Tuesday. The German carmaker, which owns the Audi, Bentley, Bugatti, Ducati, Lamborghini, Porsche, Seat and Skoda brands, also said that uncertainty about the fallout from coronavirus meant it was impossible to give forecasts for its performance this year. "Given the present significant deterioration in the sales situation and the heightened uncertainty regarding parts supplies to our plants, production is to be suspended in the near future at factories operated by group brands," Chief Executive Herbert Diess said on Tuesday. Volkswagen's powerful works council concluded it was not possible for workers to maintain a safe distance from each other to prevent contagion and recommended a suspension of production at its factories from Friday. Production will be halted at VW's Spanish plants, in Setubal in Portugal, Bratislava in Slovakia and at the Lamborghini and Ducati plants in Italy before the end of this week, Diess said. Most of its other German and European factories will prepare to suspend production, probably for two to three weeks, while Audi said separately it would halt output at its plants in Belgium, Germany, Hungary and Mexico. Volkswagen's vast factories in Chattanooga, Tennessee, in Puebla, Mexico, and plants in Brazil were not affected, but that would depend on how the coronavirus spreads, VW said. Volkswagen has 124 production sites worldwide of which 72 are in Europe, with 28 in Germany alone. "2020 will be a very difficult year. The coronavirus pandemic presents us with unknown operational and financial challenges. At the same time, there are concerns about sustained economic impacts," Diess said.   Production in China resumes Volkswagen Group sold 10.96 million vehicles last year, putting it ahead of Toyota based on the latest figures from the Japanese carmaker. Globally, VW employs 671,000 people and it delivered 4.86 million vehicles to European customers in 2019. Only last month the car and truck maker based in Wolfsburg, Germany, predicted that vehicle deliveries this year would match 2019 sales and forecast an operating return on sales in the range of 6.5% to 7.5%. "The spread of coronavirus is currently impacting the global economy. It is uncertain how severely or for how long this will also affect the Volkswagen Group.

Recharge Wrap-up: Eigg's renewable energy grid, Wulin City Car EV looks like i3

Scotland's Isle of Eigg's electrical grid relies solely on wind, hydro and solar power. It's the first grid of its kind after switching to renewable energy from noisy, unreliable diesel generators. Scotland's renewable resources are fodder for supporters of independence form the UK, and Eigg is a perfect example of that potential. Besides being a responsible community, it also seems like a lovely place to visit. Read more at Reuters. London Mayor Boris Johnson is calling for incentives for diesel vehicle scrapping. The goal is to improve London's air quality, encourage the purchase of clean vehicles and offset the inconvenience of charging diesel cars to enter the city's proposed Ultra Low Emissions Zone.

As part of the Trans-European Transport Network (T-ENT) program, the group aims to create extended EV-friendly roadways with the UK Rapid Charge Network, connecting major cities on the islands. Plans for the network include 70 rapid chargers along 684 miles of road. The four manufacturers also want to extend the project to mainland Europe to encourage the adoption of EVs.

The City Car EV concept is slated to make its debut in November at the Guangzhou Auto Show, while a production version could make its way onto Chinese roads next year. We might have to wait until the debut to know what powers the City Car, as those details haven't been released yet. General Motors is a 43-percent stakeholder in Wuling.

Now customers will be able to use either app to pay in any of the city's 20,000 green and yellow taxis. There's no need for separate apps for separate cabs, and no need for drivers to install any new equipment. The groups behind the apps hope to expand this functionality to other cities across the country. Read more in the press release below.
