Tesla’s next-generation Supercharging hardware is finally making its way to the U.S., and it’s debuting in California.
According to longtime Supercharger watcher @MarcoRPi1 on X, the world’s first “real” V4 Supercharger station is now under construction in Campbell, California, located at 1600 W Campbell Avenue. While Tesla first debuted V4 Supercharger stalls with longer cables in the U.S. nearly two years ago, those were still powered by the older V3 cabinets. The new Campbell installation will be the first to feature both V4 stalls and Tesla’s brand-new V4 Supercharger cabinets.
The next-generation V4 cabinets are a huge leap forward. Each cabinet can now support up to eight stalls — double what V3 could manage — while delivering charging speeds of up to 500kW for cars and up to 1.2MW for the Tesla Semi. The updated design also allows Tesla to deploy stations more quickly, thanks to reduced complexity and physical footprint.
For drivers, the benefits are clear. Tesla’s S3XY lineup will continue to charge at the same 250kW rates they already experience on V3 hardware, adding as much as 200 miles of range in just 15 minutes. However, Cybertruck owners will see up to 30% faster charging speeds thanks to V4’s expanded support for 400V–1,000V vehicle architectures.
This new Supercharger generation is also built around cutting-edge power electronics with three times the power density of previous hardware. The system will be both more reliable and more cost-efficient, paving the way for faster deployment of new sites around the world.
Tesla also started deploying its first V4 stalls in China earlier this summer, but Campbell is set to become the company’s first fully fledged V4 Supercharger site globally. With construction now underway, California drivers will soon be the first in the world to experience Tesla’s most powerful charging tech to date.
As of earlier this month, Tesla has started selling Superchargers directly to businesses interested in having EV chargers on their property. The company is also preparing a new virtual queuing feature to reduce congestion at Supercharger sites by streamlining the process of securing a charging spot without having to idle in line.
