As the future of Tesla’s Supercharger team remains uncertain, the automaker is currently testing higher outputs at some of its DC fast-charging stations.
YouTuber TesLatino recently shared on X (formerly Twitter) about discovering a Supercharger station with a peak output of 323 kW, surpassing the usual 250 kW peak.

Wes Morrill, lead engineer for the Tesla Cybertruck, explained that this was part of a trial for V3+ Supercharger stations, featuring V3 cabinets and V4 charge posts. This trial, not yet available at all stations with the required hardware, promises higher power levels for Tesla drivers.
During the charging experience, Kyle Conner from Out Of Spec Studios observed the charger outputting over 900 amps to achieve the 320+ kW charging power. V3 Superchargers were originally rated at 425 amps, while V4 chargers were rated at 615 amps at 1,000 volts.
These findings suggest advanced thermal considerations in the Cybertruck, particularly in its charging inlet, to support such high charging rates without excessive heat.
The production version of the Cybertruck was unveiled in November 2023, falling short of Tesla’s initial price and range claims. Tesla has shifted focus away from the 500-mile range target, even with an additional range-extender battery pack.

Earlier this year, Elon Musk dismissed most of the Tesla Supercharger team, but later announced a $500 million expansion plan to add “thousands” of new chargers. This expansion is separate from the network’s operational costs.
Despite Tesla’s Supercharger team changes, Ionna—a charging network funded by seven automakers—has reaffirmed its commitment to install over 30,000 high-power connectors in the U.S. and Canada. BP has expressed interest in taking over Supercharger sites that Tesla no longer wishes to operate as it expands its own charging network.
