Waymo partners with Nissan, Renault on robotaxis outside U.S.

SAN FRANCISCO — Self-driving car pioneer Waymo is teaming up with automakers Renault and Nissan to make its first journey outside the U.S. with a ride-hailing service that will dispatch a fleet of robotaxis in France and Japan. The partnership announced late Wednesday underscores Waymo's ambition to deploy its driverless technology throughout the world in an attempt to revolutionize the way people get around. The Mountain View, California, company can afford to try because it's backed by one of the world's richest companies, Google, which secretly began working on driverless technology a decade ago before spinning off that project into what is now known as Waymo. After launching its ride-hailing service in France and Japan, Waymo intends to explore other European and Asian markets with Renault and Nissan. "This is an ideal opportunity for Waymo to bring our autonomous technology to a global stage," Waymo CEO John Krafcik said. Waymo, Renault and Nissan didn't set a timetable for when their ride-hailing service will launch. They left most other details vague. It seems likely it will still be several years before Waymo will be in a position to pose a serious challenge to Uber, the world's largest ride-hailing service. Although Waymo's self-driving technology is widely considered to be the world's most advanced, it still isn't adept enough to be trusted without a human poised to take control in case something goes awry with the robot. Waymo had hoped to launch a fully autonomous ride-hailing service last year in the Phoenix area, but instead is still keeping human safety drivers in those vehicles more than six months after it rolled out. That service, known as Waymo One, is still only offering rides to a few hundred passengers that previously participated in a test program. Krafcik told the German newspaper Handelsblatt last year that Waymo will likely use a different brand for its ride-hailing services outside the U.S. That could be one reason Waymo is working with France-based Renault and Japan-based Nissan, household names in their home countries. Waymo has previously struck deals with two automakers, Fiat Chrysler and Jaguar, but those involved ordering tens of thousands of vehicles to be equipped with self-driving technology for services in the U.S. So far, Waymo is only using Fiat Chrysler minivans for its Phoenix service. The partnership with Renault and Nissan also involves a long-time alliance they formed with Mitsubishi.

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.

Hurricane Sandy cost automakers 15,000 vehicles, may have ruined up to 200k

Hurricane Sandy was the largest Atlantic storm in US history, and its total economic impact is just now coming into view. According to Automotive News, Toyota, Chrysler, Nissan and Honda are set to scrap around 15,000 new vehicles ruined by the storm. Nissan alone accounts for about 40 percent of those, with 6,000 Nissan and Infiniti models deeded "un-saleable" due to damage. The company saw 56 dealerships shuttered due to the storm, but 51 of those have since reopened.
Toyota, meanwhile, had some 4,000 vehicles at its Newark port facility, and of those, 3,000 may be scrapped. An additional 825 were dealer inventory when they were ruined. Honda and Acura dealers are reportedly sending 3,440 vehicles to the salvage yard. By comparison, Chrysler weathered the storm fairly well with 825 units destroyed, while Hyundai suffered only 400 lost units and Kia scrapped around 200.
As you may recall, Fisker also suffered some losses, and Automotive News reports the manufacturer saw 320 Karma models damaged beyond repair. Ford and General Motors have yet to come up with estimates, and no automaker has commented on the full cost of replacing the vehicles.
