Tesla’s pushing electric vehicle charging into new territory with its latest Supercharger technology that’ll deliver power at speeds never seen before for passenger cars. The new V4 Cabinet system can pump out 500 kilowatts to passenger vehicles and up to 1.2 megawatts for Tesla Semi trucks, doubling what the previous V3 generation could handle.
Tesla’s V4 Cabinet Superchargers will deliver unprecedented 500-kilowatt charging speeds to passenger cars and 1.2 megawatts to Semi trucks.
The first 500-kilowatt site is under construction right now in Campbell, California, with another location planned for Redwood City. These stations are entering the permitting process as of late 2024, and Tesla expects to open the first sites in 2025. The company’s official timeline shows implementation starting in the third quarter of 2025.
These new cabinets represent a major technical leap. They support electrical systems ranging from 400 volts to 1,000 volts and can handle between 1,200 and 1,500 amps of input power. That’s nearly double the 640 amps that V3 cabinets could manage.
Each V4 Cabinet can power up to eight charging posts, twice as many as previous versions, while taking up less physical space thanks to power electronics designed with three times the power density.
There’s a catch, though. Most Tesla vehicles won’t see faster charging speeds at these new stations. The Model S, 3, X, and Y will still max out at their existing 250-kilowatt charging rates. Only the Cybertruck can currently take advantage of the full 500-kilowatt capability, thanks to its 800-volt structure.
Cybertruck owners will see up to 30% faster charging at V4 stations compared to older V3.5 locations. The wide voltage range means these chargers can work with current electric vehicles and future models expected to use higher-voltage battery systems. Vehicles that can handle the power will add up to 200 miles of range in just 15 minutes.
The improved design should speed up how quickly Tesla can build new sites. The smaller footprint and reduced complexity make permitting and construction faster while cutting down on maintenance needs and operating costs. The system operates with efficiency rated above 96%, ensuring minimal energy loss during the charging process. The V4 upgrades aim to improve overall charging efficiency across Tesla’s expanding network.
