Tesla PSUs save time and cost

Tesla has shared new details about the prefabricated supercharger units (PSUs) made in Buffalo, New York.

In tweets accompanied by a short video and photos, the EV maker explains that PSUs are fully assembled supercharger sites that come with stalls mounted on a concrete slab and electrical components prepared for grid connectivity, Inside EVs explains.

This enables new supercharger sites to be ready significantly faster, reducing the time needed for construction to days instead of weeks.

Tesla says it had 40,000 superchargers at more than 4000 global locations by November last year, and it plans to add at least 10,000 superchargers this year.

The PSUs are using V3 superchargers, with charging covered at Tesla’s recent Investor Day, and Tesla is reportedly planning some V4 ones.
