Nissan Leaf battery cells put through torture test, live to charge again

One minor chink in the armor of the Tesla Model S is that a small number have caught fire, once their battery packs were penetrated. Nissan Leaf drivers, however, might just be able to weather such an event without an ensuing CarBQ. Our evidence for such a claim? A video that has surfaced of cells from a Leaf pack undergoing a battery of torture tests (pun somewhat-ashamedly intended). Shared by folks at the Hybrid Auto Center in Las Vegas – who offer for sale, among other things, used Leaf lithium battery modules – the footage shows salvaged cells being brutally assaulted with a screwdriver, and later, a propane torch. Granted, these tests are not the same thing as flinging a piece of metal into a working pack at 70 miles per hour, but they do claim to show that a puncture does not always equal a fire. Oh, and don't try this at home. When pierced through by the flat head tool, there is no explosion or eruption of flame. Instead, a rather modest wisp of smoke shyly emerges as the electrolyte next to the shorted area of the fully-charged foil pouch reacts with the influx of oxygen. Again and again, the blade descends, until the cell is riddled with holes. No fire. Amazingly, when connected with a voltmeter afterward there are still plenty of signs of life, and when it is charged and discharged (off-camera), it reportedly suffers only a slight loss of charge capacity. The video goes on to show another cell attacked with open flame with similar results. While the demonstration is, perhaps, somewhat crude, the message it sends is loud and clear: lithium batteries can be safe and rather robust, despite some freak accidents.

2016 Civic, Sonata, Lexus RX, and Altima earn TSP+ from IIHS [w/videos]

The 2016 Honda Civic sedan, Hyundai Sonata, Lexus RX, and Nissan Altima started the year with a bang by earning Top Safety Pick+ honors from the Insurance Institute for Highway Safety. They join 48 other 2016 model year vehicles that IIHS already tested that received the agency's top safety marks. These four models met the IIHS' latest requirement, scoring the agency's best possible score in all five of its crash tests – front, side, rear, rollover, and the difficult small-overlap – to be eligible for the safety accolade. Hyundai improved the 2016 Sonata's structure after the sedan's production began, so this rating only applied to examples produced after October. To get the TSP+ honor, a vehicle's crash prevention tech needs to earn least two points on the IIHS' scale. The lower Top Safety Pick designation can go to model with a "basic" version of these systems like a front collision warning. The Civic, Sonata, and RX scored the maximum six points to get "superior" scores for their optional crash prevention tech because they avoided collisions at up to 25 miles per hour. The Altima was successful in a 12-mph test, but the system slowed the sedan by 10 mph in the 25-mph test rather than completely stopping it. Therefore, the agency awarded the Nissan five points, which was still a "superior" score. You can watch the small-overlap tests for the Civic, RX, Altima, and Sonata respectively below.

Four more vehicles earn the 2016 TOP SAFETY PICK+ award ARLINGTON, Va. — The Honda Civic 4-door, Hyundai Sonata, Lexus RX and Nissan Altima are the latest vehicles to earn the top award from the Insurance Institute for Highway Safety. The four vehicles join the 2016 winner's circle just one month after the initial crop of 48 TOP SAFETY PICK+ winners was announced. The requirements for TOP SAFETY PICK+ were tightened for 2016. To qualify, winners must earn good ratings in each of the Institute's five crashworthiness tests and have an available front crash prevention system earning an advanced or superior rating.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.
