CES 2020 and Carlos Ghosn | Autoblog Podcast #609

Welcome to a new decade of the Autoblog Podcast. In this week's episode, Editor-in-Chief Greg Migliore is joined by Senior Editor Alex Kierstein and Senior Editor, Green, John Beltz Snyder. First they talk about their early impressions of CES 2020 in Las Vegas, in particular how interesting Sony's Vision-S Concept is. Then they talk about the intriguing saga and daring escape of former Nissan boss and global fugitive Carlos Ghosn. After that, they turn their attention to what they've been driving, including the Genesis G70, Chevy Blazer and Hyundai Santa Fe. Finally, they help a listener pick a new fun toy to replace an unloved Porsche Cayman in the "Spend My Money" segment.

DC fast charging not as damaging to EV batteries as expected

As convenient as DC fast charging is, there have been lots of warnings that repeated dumping of so many electrons into an electric vehicle's battery pack in such a short time would reduce the battery's life. While everyone agrees that DC fast charging does have some effect on battery life, it may not be as bad as previously expected. Over on SimanaitisSays, Dennis Simanaitis, writes about a recent presentation by Matt Shirk of the Idaho National Laboratory (INL) called DC Fast, Wireless, And Conductive Charging Evaluation Projects (PDF) that describes an ongoing test of four 2012 Nissan Leaf EVs that are being charged in two pairs of two. One pair only recharges from 50-kW DC fast chargers, which the other two sip from 3.3-kW Level 2 chargers exclusively. Otherwise, the cars are operated pretty much the same: climate is automatically set to 72 degrees, are driven on public roads around Phoenix, AZ and have the same set of dedicated drivers is rotated through the four cars. "Degradation depends more on the miles traveled than on the nature of recharging." What's most interesting are the charts on page seven of Shirk's presentation (click the image above to enlarge), which show the energy capacity of each of the four vehicles. When they were new, the four batteries were each tested to measure their energy capacity and given a 0 capacity loss baseline. They were then tested at 10,000, 20,000, 30,000 and 40,000 miles, and at each point, the DC-only EVs had roughly the same amount of battery loss as the Level 2 test subjects. The DC cars did lose a bit more at each test, but only around a 25-percent overall loss after 40k, compared to 23 percent for the Level 2 cars. Simanaitis' takeaway is that, "INL data suggest that the amount of degradation depends more on the miles traveled than on the nature of recharging." The tests are part of the INLs' Advanced Vehicle Testing Activity work and a final report is forthcoming. These initial numbers from IPL do mesh with other research into DC fast charging, though. Mitsubishi said daily fast charging wouldn't really hurt the battery in the i-MiEV and MIT tests of a Fisker Karma battery showed just 10-percent loss over 1,500 rapid charge-discharge cycles.

Nissan and NASA team up on autonomous zero-emissions test fleet

Nissan and NASA have announced a collaboration on autonomous vehicles that, if we're honest, makes more sense to us than Infiniti partnering with Red Bull. The two are commencing a five-year R&D program to explore autonomous drive systems, human-machine interfaces, network-enabled applications, and software analysis and verification. What's more: the test fleet will be zero emissions and rolling around NASA's Ames Research Center by the end of this year. We will assume that means autonomous Leafs, but Nissan could be working on a new vehicle for the purpose. Nissan CEO Carlos Ghosn said the company will begin offering autonomous features "beginning in 2016," and wants to have commercially available self-piloting vehicles that can "navigate in nearly all situations," including urban environments, by 2020. Who better to assist than the people who put a self-driving rover on a planet that never gets closer than 34 million miles away? What does NASA get out of it? Access to Nissan's materials and component developments, prototyping systems, and robotic software test beds. Sounds like everybody wins. The press release below has more information. Nissan and NASA partner to jointly develop and deploy autonomous drive vehicles by end of year SUNNYVALE, Calif. Jan. 8, 2015 - Nissan Motor Co., through its North American-based organization, and NASA today announced the formation of a five-year research and development partnership to advance autonomous vehicle systems and prepare for commercial application of the technology. Researchers from Nissan's U.S. Silicon Valley Research Center and NASA's Ames Research Center at Moffett Field, Calif., will focus on autonomous drive systems, human-machine interface solutions, network-enabled applications, and software analysis and verification, all involving sophisticated hardware and software used in road and space applications. Researchers from the two organizations will test a fleet of zero-emission autonomous vehicles at Ames to demonstrate proof-of-concept remote operation of autonomous vehicles for the transport of materials, goods, payloads and people. For NASA, these tests parallel the way it operates planetary rovers from a mission control center. The first vehicle of that fleet should be testing at the facility by the end of 2015. "The work of NASA and Nissan – with one directed to space and the other directed to earth, is connected by similar challenges," said Carlos Ghosn, president and CEO of Nissan Motor Co.
