Tesla is pushing its charging infrastructure in two directions at once. The company will operate public Megacharger sites at three electric-truck depots owned by Forum Mobility, a major US heavy-duty charging operator. Forum Mobility is about to break ground on four new California depots, and Tesla will run the chargers at three of them.

Separately, Tesla has deployed its first 'Accordion' Supercharger, a pre-assembled unit that carries 16 stalls on a single truck and costs about 20% less to install than a conventional site. Tesla's charging team says the goal is to pre-assemble every Supercharger in a factory.

The two announcements are separate but complementary. Both show Tesla trying to scale charging more quickly, but they target different parts of the business: one expands Tesla's role in heavy-duty truck charging at sites it does not own, while the other improves the economics and speed of building out its own Supercharger network.
