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.

Volkswagen's 261-mpg hand-built XL1 headed for Geneva

After years of rumors, development and testing, the Volkswagen XL1 is finally about to become a reality. The project that began life as a daring 1-Liter concept car in 2002, will finally get its production-ready curtain call at the Geneva Motor Show in just a few weeks.
As soon as it hits the streets, the two-seat XL1 will instantly become the most fuel-efficient and most aerodynamic production car in the world. The car uses a plug-in hybrid system to achieve mind-blowing consumption of just 0.9 liters of diesel fuel consumed every 100 kilometers (and average of roughly 261 miles per gallon). Plus, the XL1 can go up to 50 kilometers on its battery power alone. Coefficient of drag is a miniscule 0.189, thanks to a tiny frontal area and an obviously slippery shape.
XL1 power comes from a two-cylinder diesel motor connected to a seven-speed dual-clutch gearbox, while the 20 kW electric motor is fed by a lithium-ion battery. Both combine to give the XL1 performance figures that are, while not stirring, not shabby considering its extreme frugality: 0-62 miles per hour comes up in 12.7 seconds and top speed is nearly 146 mph.

Recharge Wrap-up: Toyota Prius airbag recall, Peugeot launches eU01s e-bike

Toyota is recalling 7,600 Prius vehicles for an airbag issue. Certain examples of the 2016 Prius could have malfunctioning inflators that could cause the passenger side airbags to deploy accidentally. There are no known injuries from the faulty airbags, but Toyota says, "This has been observed when the vehicle is parked and unoccupied for a period of time." Toyota also says this issue is unrelated to the massive recall of airbags supplied by Takata. The automaker will contact affected owners to arrange free repairs. Read more at Automotive News. Peugeot is adding another e-bike to its portfolio with the eU01s. What sets this electrically assisted bicycle apart from both regular bikes and other pedelecs is its ability to propel the bike to 28 mph under electric power. It comes with either a 400- or 500-Wh lithium-ion battery, providing 47 or 59 miles of range, respectively. It also offers an optional on-board computer with its 4.3-inch screen, through which riders can customize the electric assistance, get directions, receive sports coaching, and connect their smartphone. Earlier this year, Peugeot also launched its e-Kick scooter and folding eF01 e-bike. Read more at Green Car Congress. BYD is expanding its manufacturing facility in the US. In the second of three phases for the plant, BYD is adding onto its factory in Lancaster, California, where it currently builds electric buses. The Chinese company plans to triple the number of employees, up from the current 400, as it expands the facility by 40,000 square feet. BYD plans to build medium- and heavy-duty trucks at the plant, but declined to comment on whether it has plans to build light-duty vehicles there. Read more at Automotive News. The German states of Hesse and Baden-Wuerttemberg are suing Volkswagen over the Dieselgate scandal. The states are joining other investors seeking damages over losses incurred because of the automaker's emissions cheat device. Hesse Finance Minister Thomas Schaefer said the scandal cost the state about $4.4 million in stock losses, while Baden-Wuerttemberg likely lost closer to $450,000. Bavaria said earlier that it would sue Volkswagen on behalf of its pension fund for civil servants, which lost around $780,000. Read more from Automotive News Europe.
