A recent study spearheaded by Tesla Motors has led to the development of an electric vehicle battery that could last up to one-million miles, or roughly double the current lifespan of battery packs fitted to today’s EVs.

  • Dalhousie University in Nova Scotia, Canada, was behind the three-year study into developing these longer-lasting batteries.
  • The research team has an exclusive agreement with Silicon Valley-based Tesla Motors.
  • In April of this year, Elon Musk, Tesla’s CEO, stated the automaker would soon have batteries capable of lasting one-million miles.

According to Elon Musk, Tesla’s CEO, the company’s current battery packs should be good for between 300,000 to 500,000 miles, or between 1,000 to 1,500 charge cycles, before needing replacement. The researchers found that its new battery pack was good for 4,000 charge cycles, or the equivalent to that one-million mile mark. Even at this impressive mileage, the research found that battery performance had degraded by only 10 percent.

Commercial implications

While a million-mile battery pack sounds nice for the average Tesla owner, this news has much greater impact as the company looks to get into long-haul trucking fleets. Tesla is actively working on an electrified tractor trailer which, at some point, could also feature full self-drive capability. This market segment puts massive miles on its vehicles, so having a battery pack able to withstand near-constant use, and more frequent charging, could help save fleet buyers money in the long run.

As reported by Wired, Tesla filed a patent for a new battery almost at the same time that this study was published. Given that the research paper basically provides a blueprint for the battery tech itself, it’s possible Tesla’s patent could be for a battery pack with even greater longevity. With the reveal of a Tesla pickup truck likely by year’s end, it’s possible Tesla will also reveal its cutting-edge battery at the same time.

WHY THIS MATTERS

To woo truck companies and fleet buyers, the economics have to be in place. With a longer-lasting battery pack, Tesla can give its commercial vehicles a significant cost advantage.
