Fisker stock trades halted as talks with Nissan collapse

Fisker's talks with a large automaker for a potential deal have collapsed, it said on Monday amid growing uncertainty for the cash-strapped startup that last week paused electric-vehicle production.  Trading in the shares of the company, which did not name the automaker with which it was in talks, has been halted pending an announcement.  Fisker also said it will not be able to meet a closing condition related to its attempt to raise up to $150 million in funding by selling convertible notes after missing an interest payment.  Separately, Fisker said it would ask investors to vote on a proposal for a reverse stock split at a shareholder meeting on April 24, as it looks to maintain compliance with the Nasdaq's listing norms.  Reuters had reported earlier this month that Nissan was in advanced talks to invest in the company, however, earlier in the day, the Japanese automaker held an event in which it announced a long-term business plan, including its EV strategy, and said it was looking for partners in the United States.  Raising funds has been hard for loss-making electric vehicle startups, which have little in way of revenue as they struggle to ramp up production and deliver to customers, as the companies battle stiff competition and a tough economy.  The EV startup's shares have cratered this year, losing more than 90% of their value, after it flagged going concern risk in February and paused investments in future projects until it secured a partnership with an automaker.  Fisker pivoted to a dealer-partner model earlier this year, after it delivered less than half of the vehicles it made in 2023 due to logistics issues.    Earnings/Financials Fisker Nissan

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.

Roller coaster or racecar, which pulls more Gs?

Looking for a thrill? You're not the only one. You'll find kindred spirits at airfields going up for a skydive, atop bridges and towers with bungees attached to their feet and standing in line for roller coasters at the local amusement park. But you'll also find them in the paddock at the racing circuit.
So what's the commonality? G-force. It's like gravity, only in each of these cases, it's experienced by human invention. But which activity subjects your body to the greatest amount of g-force? That's what Nissan set to find out.
Before putting them back in the cockpit, Nismo sent out two of its young hot-shoes - Jann Mardenborough and Mark Shulzhitskiy - to an amusement park in the UK with a camera and a g-force meter to find out if any of the coasters could produce as much lateral gravitational force as an LMP2 racing car. See what they found in the pair of videos, below.
