In a series of tweets, Kyle Conner from Out of Spec detailed an unprecedented event originally observed by X user @TesLatino: a Tesla Supercharger outputting significantly higher power than previously recorded. Kyle, an experienced tester and reporter in EVs and charging, shared his excitement and insights over a new high amperage observed at a Tesla Supercharger.

Record-Breaking Power Output

Conner’s initial post highlighted that this was the first time they had seen a Tesla Supercharger exceeding the typical 250 kW power limit. He mentioned FaceTiming @TesLatino to confirm the high amperage output, noting that the system must have been delivering over 900 amps to achieve a power output of more than 320 kW.

Clarifications and Additional Context

In a follow-up post, Kyle clarified several points to provide a comprehensive understanding of the situation:

  • Unprecedented Amperage: Up until this event, the highest amperage Conner had observed on any Tesla charger was around 712 amps. This new observation marked a significant increase.
  • V4 Charger Misconception: Conner noted that the setup was not a V4 charger but merely the dispenser. This distinction was important as the V4 chargers are anticipated to support even higher voltages and potentially higher power outputs.
  • Uncertain Availability: It remains unclear if this high current capability is available at all V4 dispenser sites or if this was a unique instance.

Kyle also mentioned the Cybertruck’s unique requirements during the charging handshake process, which may have influenced the observed amperage. The data aligns with Tesla’s need to meet the demanding charging needs of their current and future vehicles, like the Cybertruck, which requires high currents for optimal charging.

Implications for Future Tesla Chargers

Conner concluded by expressing enthusiasm for the capability of the V3/3.5 cabinets to handle such high current. He speculated that the forthcoming V4 chargers, expected to support high voltage (950V+), would enable vehicles like the Cybertruck to achieve over 330 kW charging speeds regularly.

Update on Tesla’s Testing

In an update, Kyle clarified that this was not a bug but part of Tesla’s trial of some V4 dispenser sites with an amperage unlock. He expressed eagerness to test these capabilities further with his Cybertruck, highlighting the community’s interest in Tesla’s advancements.

This event marks a significant development in Tesla’s Supercharger technology, pushing the boundaries of fast charging and setting the stage for future innovations in electric vehicle infrastructure.
