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.

Why this could be the perfect time for Apple to make a car play

While the automotive and technology worlds have been pouring billions into autonomous vehicles (AVs) and preparing to bring them to market soon as shared robo-taxis, Apple has mostly sat on the sidelines. Of course, Apple is the last company to ever make its intentions known, and the super-secret tech cult giant hasn't been totally out of the AV game based on the clues that have slipped out of its Cupertino, Calif., citadel over the past few years. Related: Apple self-driving cars are real — one was just in an accident News first broke in 2015 that it had assembled an automotive development team, in part by poaching high-profile talent from car companies, to work on a top-secret self-driving vehicle project code-named Titan. (Thank you very much, Nissan.) Apple also subsequently broke cover by making inquiries into using a Northern California AV testing facility and receiving a permit to test AVs on public roads in California. But then as the AV race started to heat up in the last few years, Apple reportedly began scaling back its car activities by downsizing team Titan. More recently, Apple's car project has shown signs of life with the hiring a high-level engineer away from Waymo and luring one Tesla's top engineers and a former employee back to Apple. It also inked a deal with Volkswagen to provide a technology platform and software to convert the automaker's new T6 Transporter vans into autonomous shuttles for employees at tech company's new campus. That is a far cry from giving rides to Wal-Mart shoppers, like Waymo is doing as part of its AV testing in Phoenix. But this could be the perfect time for Apple to enter the AV market now that ride-sharing is reaching critical mass and automakers and others are planning to deploy fleets of robo-taxis. Apple could easily establish a niche as a high-end ride-sharing service – and charge a premium – given its cult-like brand loyalty and design savvy. The growth of car subscription models could also play in Apple's favor since is already has many people hooked on paying for phones in monthly installments – and eager to upgrade when a new and better model becomes available. To achieve this, some believe Apple will fulfill co-founder and CEO Steve Job's dream of building a car. And as the world's first and only $1 trillion company it's sitting on a mountain of cash that certainly gives it the means. But other tech darlings like Tesla and Google have discovered how difficult it can be to build cars at scale.

2013 Nissan Pathfinder: July-September 2013

This Nissan is the most in-demand long-term vehicle we've ever had.
They may not readily fall into the sweet spot of driving enthusiasts, but our year-long test of this Nissan is proving to be an object lesson in why crossovers are so popular - especially large ones like our three-row Pathfinder. In fact, it's been so busy that it's hardly been at a standstill long enough to pen an update, which is why this one is late. Simply put, this Nissan is the most in-demand long-term vehicle we've ever had, racking up more miles and more long-distance trips than any LT vehicle in the Autoblog stable.
