Tesla Battery Day 2020: How, When and Where to Watch Elon Musk September 22 Livestream

Elon Musk has teased "big" news will be unveiled during a Tesla event this week focusing on the tech that powers his company's electric cars.

The billionaire CEO hyped up the showcase on Twitter yesterday as followers asked for hints about what is expected from the "Battery Day" presentation, previously described by Musk as potentially being "one of the most exciting days in Tesla's history."

While executives remain tight-lipped about exact details, statements from Musk suggest the event will outline how the company is reducing the cost of cell production, bulking up partnerships with the likes of Panasonic and CATL and working towards the release of a powerful pack capable of lasting for one million miles of operation.

It comes as Tesla's stock continues to ride a positive trajectory and Musk's personal net worth soared to $107 billion, earning him the title of world's third richest person.

With speculation mounting online, it's clear there is significant anticipation of what the pioneering electric car-maker can do to stay ahead in a field that is seeing increased levels of competition, including from legacy brands stepping into its territory.

How and where to watch Battery Day 2020

In earlier years, the event would have been held in front of a busy crowd of EV industry professionals and press, but the lasting impact of the ongoing COVID-19 pandemic has meant it will be presented virtually—streamed live on the Tesla website.

The Battery Day webcast will begin immediately after the conclusion of Tesla's 2020 annual stockholders meeting, which starts on Tuesday at 1:30 p.m. Pacific Time (4:30 p.m. ET). For viewers in the U.K, that is 9:30 p.m. BST.

A placeholder section for the stream has already been added to the Tesla site, meaning that will be one of the main destinations for viewing. While unconfirmed, it is likely the webcast could also be made accessible via the company's Twitter or YouTube.

Despite glimmers of hype and several alleged photo leaks, Musk hasn't confirmed what the public should expect from the event. But a July 22 earnings call indicated he would be likely to discuss how Tesla can grow cell production at affordable prices.

"That's the real limit. So that's why we're going to talk about a lot more about this on Battery Day because this is a fundamental scaling constraint," Musk said.

"And any part of that supply chain or pricing at the cell level will be the limiting factor. So whatever may be an error from mining to refining, those many steps that are refining to cathode and analog formation, cell formation, whatever the truck point is, that will set growth rate. And so we expect to expand our business with Panasonic, with CATL, with LG, possibly with others. And there's a lot more to say on that front," he added.

Ultimately, if Tesla can find a way to create higher-capacity battery packs at a reduced cost it could bring down the prices of its electric cars for consumers.

While the Tesla reveals are fully expected to translate to stock movement, some analysts have said that Musk often makes promises that are far on the horizon.

"We caution investors against diving head-first into... claims that are years away," Chris McNally, of Evercore ISI, said in a financial note last week, MarketWatch reported.

Tesla stock closed at $442.15 Friday and is up over 420 percent for the year, according to CNBC. On September 17, Musk teased that Battery Day will be "very insane."
