VW quite interested in solid-state batteries for EVs

Volkswagen is about to make a decision about which advanced battery technology the automaker will seriously investigate to give its electric vehicles more range. VW will decide by July if it will use solid-state batteries made by US-based QuantumScape Corp. in future EVs, according to Bloomberg News. Last year, VW bought a five-percent stake in QuantumScape, which was founded by ex-Stanford University researchers. The lure is that QuantumScape's solid-state batteries may provide a single-charge range of as long as 430 miles. That's more than three times the current range of the VW e-Golf electric vehicle the company recently started selling to the public and is substantially longer than the single-charge range of the Tesla Model S electric sedan. The batteries are also fireproof, making VW's potential decision one with an eye towards more vehicle safety. Solid-state battery technology, in which solid lithium electrodes are used instead of liquid electrodes such as those in lithium-ion batteries, are the subject of research at other automakers and suppliers as well. Toyota says they could be here by 2020. Recently, the cordless vacuum cleaner maker Dyson acquired a $15-million equity stake in Michigan-based battery maker Sakti3 with the idea of using the startup's solid-state batteries in its products. General Motors also has a minority stake in Sakti3, which was spun off from the University of Michigan.

What the Volkswagen I.D. concept tells us about the post-TDI future

If you've been paying attention, 2016 hasn't been a great year for Volkswagen. The TDI scandal removed VW's last crutch between our internal combustion present and the electric future, and so the company found itself scrambling to shift resources to show what's next right now. It's naive to assume that this is truly the sort of fairytale comeback story that VW's spin doctors would have us all believe, but it's notable that instead of flinching or pointing fingers, the engineers got to work. What they've produced is the I.D. concept, the third wave in VW's volume car history after the Beetle and Golf. The transaxle Golf was more than simply an updated Beetle, and likewise the I.D. is more than an electrified Golf. VW says the I.D. won't replace the Golf, but they said the same thing about that car replacing the Beetle. It's only a matter of time. VW says the I.D. won't replace the Golf, but they said the same thing about that car replacing the Beetle. It's only a matter of time. The I.D. approach is refreshingly simple: no carbon fiber chassis, no exotic battery chemistry, no outrageous concept car styling. The MEB chassis (the German acronym for modular electric platform) is made out of a traditional mix of high-strength steel grades to save costs and utilize existing factories. The battery is integral, not swappable, to reduce complexity and increase structural rigidity. It's also uses lithium-ion chemistry because of a proven track record and an existing (albeit deficient) supply chain. Contrast that with the e-Golf, which shares its chassis with the conventional internal-combustion cars. Fitting the battery and its ancillary systems became complicated and expensive. The skateboard installation in the I.D. will allow the pack to be optimized for the space available, reducing costs. As we've already reported, MEB will be shared across all VW Group brands to achieve an economy of scale, and the modular platform can be stretched to the size of roughly a Passat and down to a car slightly smaller than the I.D. It can be given all-wheel drive, although VW's e-mobility chief Christian Senger is quick to point out that the standard rear-drive configuration provides plenty of traction because of optimal weight distribution achieved with battery in the middle of the chassis. It makes all-wheel drive more of a bonus rather than a necessity in bad weather.

Volkswagen and Porsche recall Touareg and Cayenne

The Basics: Volkswagen and Porsche will recall about 800,000 units worldwide of the 2011-2016 Touareg and Cayenne, according to Reuters. Of these, there are 88,300 Cayennes and 46,700 Touaregs in the US. The Problem: A securing clip on the brake pedal hinge could be missing. This can cause the pedal pivot pin to move, and "the pedal could lose guidance," according to Volkswagen's statement. Over time, the problem might cause the pedal hinge to fracture, which could make it impossible to activate the brakes. Injuries/Deaths: Porsche's statement says, "this is a purely precautionary measure, as there have been no reports of accidents or injuries as a result of this concern." Volkswagen's statement reports, "no incidents have occurred in the US to date. However, single events have been reported overseas." The Fix: Dealers will inspect the clip and reinstall it if necessary. If you own one: Porsche says it discovered the problem during internal inspections.

Voluntary safety recall: Porsche is conducting an examination of 409,477 Cayenne models worldwide from model years 2011 to 2016 for a precautionary inspection, of which 88,300 are in the United States and 10,370 are in Canada. The reason for this is a clip may have become dislodged from the pedal bracket. We are implementing a voluntary recall to inspect all Cayenne vehicles built during that period to ensure the clip is present and to re-install it if necessary. The problem was identified during internal inspections and remedied in production. This is a purely precautionary measure, as there have been no reports of accidents or injuries as a result of this concern. ### Volkswagen Statement Volkswagen has notified NHTSA of an upcoming voluntary safety recall affecting approximately 46,700 Volkswagen Touareg vehicles from the 2011-2016 model years. In rare cases, a securing clip at the brake pedal hinge may be missing. If the clip is missing, the pedal pivot pin could start to move and the pedal could lose guidance. If this remains undiscovered, the pedal hinge could fracture after continued operation, allowing the pedal to dislodge. A customer may not be able to properly actuate the brakes with a dislodged brake pedal. A non-functional brake or reduced braking power could result in a crash. No incidents have occurred in the U.S. to date.
