Recharge Wrap-up: Tesla owner's garage makeover, Lucid signs deal with LG Chem

A Tesla owner has remodeled his garage to resemble a Tesla showroom. The Model S owner, who also runs Teslainventory.com, painted one wall a very specific shade of red, mounted a Tesla logo on it, and even bought the same table and stools used in some showrooms. He also documented the transformation, and gives tips on how other fans can give their own garage a makeover. Check it out in the video above, and read more at Electrek. Lucid Motors will source lithium-ion batteries from LG Chem. Lucid's batteries will use proprietary cell chemistry developed in partnership with LG. Lucid also has a battery supply deal with Samsung SDI for its first vehicle, but says it could use batteries for other companies through its own supply business, or for specific performance variants of its electric sedan. "The differing performance attributes available from the two cell suppliers provide Lucid with maximum flexibility to select the best cell for each application," Lucid says.

As other automakers are building their own mass market EVs, these three are teaming up in order to be able to offer their own models at prices competitive to their gasoline powered counterparts. According to the Nikkei, EVs from the three companies will all use the same platform as the upcoming 2018 Nissan Leaf, and will share motors, inverters, and batteries.

Recharge Wrap-up: Renault-Nissan at COP21, fast charging viability

Nissan and Renault's combined fleet of 200 EVs drove over 175,000 kilometers (about 108,700 miles) during the COP21 environmental summit in Paris. The largest fleet of EVs for any international conference served as shuttles for attendees, saving almost 182 barrels of oil and 18 tons of CO2 emissions. In addition to providing the Nissan Leaf, Nissan e-NV200, and Renault Zoe EV shuttles, the Renault-Nissan Alliance also set up a network of 90 chargers to support the fleet. 13 of the 27 quick and semi-quick chargers will remain in place for public use.

The company will implement new and upgrade existing traffic technologies in the city, including cloud-based traffic management software, local controller software and an adaptive traffic control system designed to improve traffic flow and safety. In a college town with highly varying numbers of students and visitors throughout the year, "the need to move traffic in and out of the city efficiently is crucial not only for economic and environmental impacts, but for quality of life for Ann Arbor residents," says Marcus Welz, president of Siemens Intelligent Traffic Systems. Many Ann Arborites (your author included) would surely agree. Read more at Green Car Congress, or in the release from Siemens.A study in Ireland found that public fast charging could soon become commercially viable. The researchers found parking spots to be the most popular public charging locations, and that fast chargers saw the most frequent use, suggesting commercial viability for the infrastructure in the short- to medium-term. The study also found that most drivers prefer to charge at home, and do so during peak hours. Incentivization could be necessary to break people from this habit. Read more at Green Car Congress.

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.
