What is the maximum voltage of Tesla's V4 Supercharger?

The maximum voltage of Tesla's V4 Supercharger is 1000 volts.

V4 is Tesla's newer Supercharger hardware generation, designed for higher-power charging and broader vehicle compatibility. Tesla's V4 cabinet specifications list a direct-current voltage range reaching 1000 V, although the actual charging voltage depends on the vehicle's battery architecture and state of charge.

The figure describes the charger's electrical capability, not the power every vehicle receives. Charging power is measured in kilowatts and depends on voltage, current, the car's battery-management system, and thermal conditions. A vehicle may therefore charge below the station's maximum voltage.

V4 installations also introduce longer cables and updated designs intended to serve vehicles with different charge-port locations, including non-Tesla EVs in some markets. The number is sometimes confused with a car's nominal battery voltage or with the charger's maximum power rating; those are separate specifications.
