Musk: Tesla Semi ramp-up depends on battery cell supply—and infrastructure partnersMusk: Tesla Semi ramp-up depends on battery cell supply—and infrastructure partners

Tesla reported its fifth consecutive profitable quarter on Wednesday, with executives providing a relatively straightforward business update spanning the company’s automotive, energy, and energy storage areas.
Despite the challenges of the pandemic, Tesla still hopes to achieve its target of 500,000 vehicle sales this year, globally.
The long-anticipated Tesla Semi will make up a relatively small portion of those sales, but it and the Cybertruck—which in August CEO Elon Musk described as a “North American ass-kicker—are especially important ones for Tesla’s reputation in the U.S. The company provided some substantive updates about both in its quarterly financial call directly following the release of Q3 numbers.
Tesla Semi
Musk emphasized that the Semi project, while otherwise ready, is up against the production constraints of cell makers. “If we are cell-constrained it’s difficult to ramp up the Semi because there are no cells,” he said.
The Semi, Musk noted, will consume a lot of cells—4 to 6 times more than a passenger vehicle. 
“We need more cells so we can do more stationary storage, more vehicles, more vehicle lines,” he said, reiterating; “We need more cells.”
Tesla, through its Nevada Gigafactory with Panasonic, has more control over its supply than nearly any other maker of EVs; and it’s headed toward an even greater level of control, with some batteries sourced from suppliers and a plan to produce its own. CTO Drew Baglino confirmed that Tesla’s new proprietary 4680 cells—the ones introduced at the company’s recent Battery Day that could potentially help the company halve cell cost eventually—will be made at Giga Berlin at the same time as vehicle ramp-up there. 
Tesla Semi
Tesla also revealed an unexpected Semi-related detail—that it’s looking to deploy infrastructure with other parties, and aiming to settle on a standard powerful enough to be adequate to charge the truck during mandated breaks. It remains unclear if Tesla is involved either with the international standards body CharIn and other groups, which appear to be converging on a 1.2-MW standard.
That sounds quite different than the automaker’s go-it-alone approach for passenger vehicles and its Supercharger network. And it’s unclear if Tesla’s so-called Megacharger network envisioned with the Semi’s original reveal in 2017 remains part of the vision—or if it’s evolved to become something shared, in the way Tesla uses CCS in Europe.
Tesla Cybertruck
Musk said that the Cybertruck, while it presents some manufacturing challenges, is on track to be made in Austin starting next year, for initial deliveries toward the end of 2021 and a much higher level of deliveries in 2022.
“We want the car we deliver to be better than the car we unveiled,” Musk said, pointing to a number of small improvements in the truck versus what they showed.
Tesla Solar Roof
Musk again played up the business potential of insurance, as well as the solar roof and autonomous-driving robo-taxi potential. “All of these margins are going to look comically small when you factor in autonomy,” he claimed, after suggesting that insurance could be 30 to 40% of the car business. 
Battery suppliers, long playing a conservative line with respect to production and capacity, appear to be at last rising to that challenge. Just today LG Chem announced that it planned to triple its production of cylindrical cells—the sort that Tesla could use many, many more of.
