• Tesla's Battery Day event will be streamed live online, directly after a shareholder meeting that starts at 4:30 p.m. ET on Tuesday, September 22.
  • The event is expected to yield news about a long-lasting battery pack and cell production methods and chemistry changes that reduce the price of battery packs.
  • CEO Elon Musk tweeted that the event will be "very insane."
Tesla's ability to squeeze every ounce of range from its battery packs has kept the EV maker sitting pretty atop the EV pack. Tomorrow, CEO Elon Musk will present information about how the company is able to do that and potentially share news on what's happening next in its never-ending quest to extend vehicle range.
