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 may move production because of Russia's cutoff of natural gas

Volkswagen AG is exploring ways to counter a shortage in natural gas, including shifting production around its network of global facilities, signaling how the energy crisis unleashed by Russia’s invasion of Ukraine threatens to upend EuropeÂ’s industrial landscape. Volkswagen, EuropeÂ’s biggest carmaker, said Thursday that reallocating some of its production was one of the options available in the medium term if gas shortages last much beyond this winter. The company has major factories in Germany, the Czech Republic and Slovakia, which are among European countries most reliant on Russian gas, as well as facilities in southern Europe that source energy from elsewhere. “As mid-term alternatives, we are focusing on greater localization, relocation of manufacturing capacity, or technical alternatives, similar to what is already common practice in the context of challenges related to semiconductor shortages and other recent supply chain disruptions,” Geng Wu, VolkswagenÂ’s head of purchasing, said in a statement.  RussiaÂ’s decision to throttle gas supplies to Europe has raised concerns that Germany might be forced to ration its fuel. Recent news that gas storage levels hit 90% ahead of schedule has soothed fears of acute shortages this winter, but Germany faces a challenge in replenishing depleted reserves next summer without contributions from Russia. Southwestern Europe or coastal zones of northern Europe, both of which have better access to seaborne liquefied natural gas cargoes, could be the beneficiaries of any production shift, a Volkswagen spokesman said by phone. The Volkswagen group already operates car factories in Portugal, Spain and Belgium, countries that host LNG terminals. Labor hurdles To be sure, any major production shift away from EuropeÂ’s biggest economy would face significant hurdles. VW has some 295,000 employees in Germany and worker representatives account for around half the companyÂ’s 20-member supervisory board. Any shift in production would likely involve a limited number of vehicles rather than wholesale factory shutdowns. While gas supplies for VWÂ’s plants are currently secured, the company has identified potential savings at its European sites to cut gas consumption by a “mid-double-digit percentage,” said Michael Heinemann, managing director of VWÂ’s power-plant unit. Still, the carmaker said it was concerned about the effect high gas prices could have on its suppliers.

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.
