NHTSA investigating Bosch Power Xpress 240V EV chargers for fire risk

*UPDATED with Bosch's comment. Let's stamp out the flames of suspicion right up front. A new National Highway Traffic Safety Administration (NHTSA) investigation, while involving a 2013 Nissan Leaf and some smoke, is not about another EV fire. Not directly, anyway. "Nissan has determined by pictures that the car was not to blame for the incident" – NHTSA complaint This time, the subject of the NHTSA's lens is the Bosch Power Xpress 240V charging unit. NHTSA wants to know if an overheating charging cord caused smoke (NHTSA says there was no actual fire) in a Leaf owner's garage last fall. NHTSA says it will investigate, "to evaluate the scope, frequency, and consequence of the alleged defect." Up to 50 of the charging units could be involved, and NHTSA decided to act based on a single customer complaint that was filed in August 2013. The investigation opened April 15, so it will likely be a while before we know any more concrete details. For now, you can read the official details of the investigation and the original complaint - which says, "Nissan has determined by pictures that the car was not to blame for the incident. They are blaming the charging station for the failure. They have denied any warranty coverage. The burden of the bill has been placed with the customer" – below. Nissan's senior manager of corporate communications, Brian Brockman, sent AutoblogGreen a statement that says Nissan will work with NHTSA and Bosch and points out that, "This inquiry is focused on the electric vehicle charger and is directed at the charger supplier, Bosch." Requests for comment from Bosch were not returned, but we will update this post when we hear back. Bosch spokesperson Cheryl Kilborn told AutoblogGreen that, "Bosch is reviewing the filing and will work cooperatively with NHTSA as we seek to identify the root cause."

Nissan, Infiniti will each show a next-gen concept EV in Detroit

The chief designer for Nissan and Infiniti said Wednesday that both brands will debut concept electric vehicles at the 2019 North American International Auto Show in Detroit in January that will likely show off Nissan's next-generation electric drive systems and the evolution of the brands' EV design direction first hinted at with Infiniti's stunning Q Inspiration. Alfonso Albaisa, senior vice president of global design for Nissan, said the concepts will reflect a similar departure from standard vehicle proportions as the Q Inspiration. He would not say exactly what segment or segments the concepts would represent, but he dropped some hints at a couple possible powertrains for the concepts. Similar additional concepts will follow later in the year at the Tokyo Motor Show, he said. "The Q Inspiration kind of hinted at it and we avoided discussing too much about what's driving that car. Of course, we talked about VC-Turbo, which is also possible," he said in an interview with Autoblog. "But if you really look at the car, Q Insipiration shifted the cabin forward. It was the first one to break the [mold] of Infiniti. So how to still have this artistry and this sense of carrozzerie" (Italian for coachbuilding) "of Infiniti without kind of the stereotypical long hood and the cabin shifted back and the windshield has to go through the center of the front wheel, these golden rules." Infiniti debuted the Q Inspiration concept sedan in Detroit in January, with a swoopy, ghost-like design influenced by an archer shooting an arrow through the air, and innovative design features like an elongated cabin that expands interior space, a relative lack of chrome, and other features. It's powered by a compact variable compression turbocharged engine, which can change compression ratios on the fly to maximize efficiency and power, depending on the situation. But Albaisa said the two concepts for Detroit could feature Nissan's e-Power series hybrid technology, which has mostly featured in Japan, and which features small, isolated gasoline engines that exist only to charge the batteries, not drive the wheels. They will also feature a new generation of battery packs, which he calls a "magic carpet." "It's getting denser, it's getting thinner, the cars are able to get a little bit bigger, more space, we can really do much more," he said.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
