Recharge Wrap-up: Comparing Nissan Leaf performance by climate, natural gas iffy for trucks

A new Carnegie Mellon University study looks at the effects of regional climate variations on the Nissan Leaf. The study shows (unsurprisingly) that the ambient temperatures of different regions have effects on battery performance and the use of climate control, both of which affect range. Efficiency and grid mix determine regional differences in emissions per mile. CMU enumerated many of the differences in performance across the US. For instance, on the coldest day of the year, maximum range can be 70 miles on the Pacific Coast, while it is less than 45 miles in the Upper Midwest. These differences in efficiency can also affect adoption patterns. Read more at Green Car Congress. Battery charger manufacturer CTEK has licensed WiTricity wireless charging technology. CTEK looks to commercialize the wireless power transfer tech for use with electric vehicle batteries, making the "plug-in" aspect of EV charging unnecessary. WiTricity's charging technology stands out for its ability for distance charging via magnetic near field. "We are excited to be on the forefront of the next generation of battery charging products for consumers and industry, and look forward to leveraging WiTricity's ground-breaking technology to bring a new level of convenience and ease of use to market," says CTEK CEO Jon Lind. Wireless charging is convenient for the public, but also especially useful for emergency vehicles, which need to be ready at a moment's notice but also keep electrical systems online while the car is parked.

Switching heavy trucking fleets from diesel to natural gas could make economic sense, but the environmental benefits aren't as certain, according to a new study from UC Davis and Rice University. Certain regions - particularly California, the Great Lakes and mid-Atlantic regions - could benefit from the switch with minimal investment. "But to have an environmental advantage for reducing greenhouse gas emissions would take significant policy intervention," says Amy Myers Jaffe, executive director for Energy and Sustainability at UC Davis. This would mean stricter efficiency standards for natural gas trucks, as well as stronger regulations for methane leakage. Read more in the press release from UC Davis below.

Nissan shares slide 5% after report Renault exploring stake reduction

TOKYO — Shares of Nissan Motor Co slumped 5% on Monday, their biggest fall in more than a month, following a report that top shareholder Renault may consider lowering its stake in the Japanese automaker. Bloomberg reported on Friday that Renault may consider lowering its Nissan shareholding as part of plans to separate its electric vehicle business. The French car maker has been pushing ahead with plans to split its electric and combustion-engine businesses in an attempt to catch rivals such as Tesla and Volkswagen On Friday, Renault said all options were on the table for separating the electric vehicle business, including a possible public listing in the second half of 2023. Any plans would be subject to approval from alliance partner Nissan, Renault finance chief Thierry Pieton said, adding the Japanese automaker was "in the loop" as Renault weighed up its options. Renault and Nissan have declined to comment on the report. Shares of Nissan fell to 509.8 yen in Tokyo, marking their biggest one-day decline since early March and underperforming an almost 2% drop in the Nikkei index. The car makers' two-decade-old alliance, which includes Mitsubishi Motors, was rocked by the 2018 ouster of alliance founder Carlos Ghosn amid a financial scandal. They have since pledged to pool more resources. In January they said they would work more closely together to make electric cars. They detailed a $26 billion investment plan for the next five years. But their unequal relationship has long been a source of friction in Japan. Renault owns 43.4% of Nissan, which in turn has a 15% non-voting stake in its shareholder. Renault bailed out Nissan two decades ago, but is now the smaller automaker by sales. Related video: This content is hosted by a third party. To view it, please update your privacy preferences.

Ghosn: Restoring Mitsubishi's reputation is biggest challenge

After news that Mitsubishi falsified its fuel economy data on every vehicle it has sold in Japan since 1991, and the tumble in the company's value that followed, the troubled carmaker has an unlikely savior. Nissan has confirmed it will purchase over one third of Mitsubishi's stock, or 34 percent. The stake is valued at $2.2 billion. Ghosn says making Mitsubishi a part of the Renault-Nissan alliance will save billions in development costs. But the merger certainly isn't without challenges. "The biggest challenge is to support Mitsubishi changing itself and growing and being profitable and restoring its reputation," said Ghosn. Nissan is a natural partner for Mitsubishi, and since the fuel economy scandal escalated from discrepancies in the data regarding Mitsubishi-manufactured, Nissan-badged Japan-market vehicles, it makes sense for the company to sweep in and save the day. Nissan itself is partially owned by Renault, and Nissan has a 15-percent stake in the French automaker. Mitsubishi's chairman, Osamu Masuko says that the merger was inevitable, that it "would have happened one day" anyway, according to the New York Times. Carlos Ghosn, chairman of both Nissan and Renault, is confident they will be able to turn Mitsubishi's fortunes around. "We have the track record to make it work", Ghosn said, referring to the Renault-funded rescue of Nissan in the early 2000s. Related Video:
