Recharge Wrap-up: Toyota FCV ready for production, Nissan tests Leaf-to-Home energy management

Toyota will begin selling its hydrogen fuel cell vehicle (FCV) in Japan in December. The US and Europe can expect to see the car become available next summer. The FCV, which will likely be called "Mirai" (meaning "future") in Japan, is ready for production ahead of its initial deadline at the end of the fiscal year in March. Toyota planned for annual production of 700 units, but might increase output to meet higher-than-expected demand, which is currently nearing 1,000 units. The cars will mostly be sold in the four cities where a hydrogen fueling infrastructure is already being put in place: Tokyo, Nagoya, Osaka and Fukuoka. Read more at Nikkei Asian Review. Nissan is testing the Leaf EV as part of an energy management system including "Leaf to Home" technology. The system allows the Leaf to help support the power grid during peak energy usage, or provide backup power to a home or building during outages, particularly in emergencies like natural disasters. Using the Leaf's battery to provide electricity during peak hours would lessen the demand on the grid and make the system work more efficiently. Furthermore, if consumers are compensated for the energy saved by using the Leaf for power during periods of high demand, it could encourage more people to adopt the EV.

CDP keeps track of how much companies are disclosing about their impact on global climate change. "The need for data on corporate climate change impacts and strategies to reduce them has never been greater," says CDP CEO Paul Simpson. "For this reason we congratulate those businesses that have achieved a position on CDP's Climate Disclosure Leadership Index." Other perfect scores were earned by Nissan, BMW, Daimler and General Motors. Read more in the press release from Honda below. Scientists at Stanford University have developed a lithium ion battery that can warn users before it overheats. A thin layer of copper between the anode and the layer separating the anode from the cathode acts as a sensor. When it detects lithium buildups from overcharging are approaching the separator, it sends an early alert long before it gets to a point where it would cause a short (which could lead to a fire). The new safety measure could be used in all sorts of battery applications, and not be limited to EVs. Learn more at Phys.org.

Recharge Wrap-up: Fiat 500X emissions, Japan EV sales down

The Fiat 500X exceeds EU emissions limits, according to environmental lobby group DUH. In dyno tests, DUH found NOx emissions in the diesel-powered 500X to be 11 to 20 times the limit with a warm engine, but closer to the limit with a cold engine. Testing of vehicles from Fiat and other automakers "point towards defeat devices," says DUH campaigner Axel Friedrich. Fiat Chrysler Automobiles (FCA) offered no comment in response to the accusations. Read more from Reuters. A UK study finds that about 20 percent of the benefits from fuel efficient vehicles are negated by a tendency for people to drive them more. The study, which covers the years 1970 to 2011, finds a significant "rebound effect," when consumers use more of a cheaper energy source. It suggests these drivers drive more not because of the fuel efficiency, but because of the lower operating costs. "Until now, we didn't know the size of this effect for British motoring," says Dr. Lee Stapleton, Research Fellow for the University of Sussex Centre on Innovation and Energy Demand. "We found evidence of a significant, long-term rebound and expect our results to be of interest for public policy." Read more at Green Car Congress. Japanese EV sales have declined for the first time ever. Sales of electric vehicles slid 22 percent in 2015, leaving them at the same levels as 2012. Low gasoline prices are to blame, as well as the late arrival of the updated Nissan Leaf, which caused potential customers to hold off on their purchase. This allowed the Mitsubishi Outlander PHEV to take the lead as Japan's best selling EV. The Toyota Prius Plug-In came in third place in EV sales, with the BMW i3 close on its heels.

Mitsubishi admits to tampering with fuel economy data

Mitsubishi admitted this week to intentionally rigging fuel-economy testing in four of its models sold in Asia. The affected models are all so-called Kei class cars with sub-660cc engines manufactured at Mitsubishi's Mizushima plant in Okayama, Japan. About 157,000 of those cars are Mitsubishi eK wagons and eK Space models, and 468,000 are re-badged Nissan Dayz and Dayz Roox cars, which Mitsubishi produces for Nissan. The matter came to light after Nissan found inconsistencies in reported mileage data, which then led to Mitsubishi launching an internal investigation. The fraud was discovered to be related to falsified tire pressure data, which has an effect on mileage results – an important matter considering these kinds of vehicles are marketed by fuel economy. Mitsubishi said it has stopped manufacturing and marketing the affected vehicles. The news caused Mitsubishi's stock to plummet over 15 percent, slicing $1.2 billion off the company's value. When the eK models hit the market three years ago, they were decorated with a Good Design Award by the Japanese Ministry of Economy – a merit that is now surely tarnished. While Mitsubishi has been suffering in the US recently, with news of the Normal, Illinois plant closing, its small Mirage model has sold well.
