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's Skoda says Ukraine partner making wire harnesses again

PRAGUE — Skoda Auto, part of the Volkswagen Group, said on Tuesday its supply partner in Ukraine had decided to restart production of wire harnesses which should allow the Czech carmaker to resume production of its electric ENYAQ iV model. Russia's invasion of Ukraine has added to supply chain problems for global automakers — which were already struggling with semiconductor shortages that have cut production — with a break in deliveries of wire harnesses from the war-torn country. While Skoda, the Czech Republic's biggest exporter, said it expects the supply of semiconductors to improve in the second half of 2022, it said the war in Ukraine and supply bottlenecks will put a significant burden on its operating business. Skoda's 2021 deliveries fell 12.6% year-on-year and earlier this month it stopped production of the ENYAQ because of harness shortages, saying that two other models were at risk because of the lack of availability of the component. "Our partner ... in Ukraine decided to restart production of wire harnesses this week, with full service and full security for workers there," Karsten Schnake, Skoda's board member for purchasing, said during its online 2021 earnings presentation. Wire harnesses form a key part of a car's electrical system, which group and guide cables inside the vehicle. "We decided to double the production in case something is going wrong, and this production will be ramped up in an alternative factory," Schnake said, adding that work there would start in three or four weeks. "Hopefully we can restart production of ENYAQ one or two weeks later when we have wire harnesses," Schnake said. Skoda delivered 878,200 cars worldwide in 2021, the first time that this had fallen below the 1 million mark since 2013. Nevertheless, the VW group brand's sales revenue rose 3.9% to 17.7 billion euros ($19.5 billion) in 2021 and operating profit rose 43.2% to 1.1 billion euros ($1 billion) as it took cost measures. Skoda did not give a financial or production outlook, saying there were still considerable uncertainties as a result of the conflict in Ukraine and the impact on its Russian operations. Skoda, like VW, has suspended production and other business activities in Russia, which was its second-largest market last year, with 90,400 vehicles delivered.

2015 will be the biggest year ever for cars at CES

Like the SEMA Show, major automakers are paying increasing attention to the CES, with 2015 expected to be one of the most auto focused yet. Ford, Volkswagen, Toyota, General Motors, Hyundai, Mazda, Audi, BMW and Fiat Chrysler Automobiles will all be in attendance when CES 2015 kicks off next week, taking up a record-breaking 165,000 square feet of space at the Las Vegas Convention Center. "We've come a long way from a single car on a carpet," Ford's Alan Hall told Bloomberg. Unlike SEMA, or a more traditional auto show, like the upcoming festivities in Detroit, CES doesn't necessarily focus on entire cars or the way they perform, but on the way our technology will interact with vehicles, and in how those vehicles will deliver information to drivers. "CES has become a major launch point for a lot of the big automakers," IHS tech analyst Mark Boyadjis told Bloomberg. "CES is a way for them to get on a global stage for technology." As for what kind of wares automakers will trot out in Las Vegas, we already know that BMW will show off an autonomous i3 electric car that can navigate its way through a multistory car park and can be hailed via a smartwatch app. According to Bloomberg, Hyundai will show off its own smartwatch app for the Genesis sedan, while Audi and Mercedes-Benz will show off autonomous vehicles next week. Automakers won't be the only companies looking to capitalize on CES. Tech firms, like chipmaker Nvidia, are becoming increasingly involved in the automotive game and will be in town showing their wares off to OEMs. "Two years ago, our booth would have been filled with PCs and people playing video games," Danny Shapiro, Nvidia's senior director for automotive business, told Bloomberg. "This year we made a strategic decision to shift the focus of the booth on automotive and de-prioritize some of the other things." Needless to say, you can expect to see a lot of news out of Las Vegas come next week. Stay tuned.
