Tesla has revealed its updated V4 Superchargers, which have a massive power increase and can charge vehicles at up to 500kW. The V4 Superchargers have been a work in progress. They were initially launched with a v3 cabinet, limiting their overall potential.
V3 and V4 Superchargers have been charging at 250kW for several years, but recently, Tesla started a public trial at some locations with Superchargers reaching power levels of 320kW. This speed bump out of the 250kW zone was our first indication that Tesla was looking to roll out improved charging speeds.
With these new V4 Supercharger cabinets, Tesla is ready to blow these numbers out of the water, however, not every car will be capable of charging at the new 500kW speeds. Fun fact: Tesla’s Superchargers first arrived with a charging speed of just 90kW.
V4 Supercharger Cabinet
The V4 Supercharger has been around for some time—it's the new one without a hole in the center. However, those were running with V3 or V3+ cabinets. Now, the V4 cabinet has arrived.
The V4 Supercharger cabinet knocks that 320kW V3+ right out of the park. It can put a massive 500kW into the Cybertruck—currently the only vehicle that can use that speed. And that 500kW works out to a blistering 1,300 mi/hr for the Cybertruck — nearly 2100 km/h of charge speed.
Part of these charging improvements come from the Cybertruck’s 800V system, so we can’t expect all these charging improvements to roll out to older vehicles. Instead, we can expect the upcoming Model Y Juniper Refresh to likely also arrive with an 800V system, with all the experience and knowledge Tesla has gained from the first year of the Cybertruck.
If the new Model Y achieves charging speeds comparable to the Cybertruck, it could deliver remarkably fast charging times. Being lighter and more efficient than the Cybertruck, the Model Y could achieve a significantly higher miles-per-hour charge rate at the same 500kW charging speed.
These new V4 chargers will support vehicles with 400-volt and up to 1,000-volt vehicle architectures, so people with non-Tesla EVs that support 1,000 volts will also see some drastic charging improvements.

V4 Megacharger
In its brief video, Tesla also showed off the updated V4 Megacharger dedicated to the Tesla Semi. The new MCS system can pull up to 1.2 Megawatts, which is 1,200 KW of pure power via the MCS connector for the Tesla Semi and its massive battery pack.
This upgrade for the Semi is going to be big, making it a prime option for companies looking to do short—and medium-haul trucking—nearly 90% of the trucking in North America.
V4 Supercharger Rollout
The rollout of V4 Superchargers will start early next year, with the first sites already undergoing permitting. Most interestingly, Tesla’s new V4 cabinet has also reduced the complexity of the Superchargers even further.
The V4 cabinet powers 8 posts, which is 2x more than the V3 cabinet. A smaller footprint and less complexity mean faster installations, which means more V4 sites faster.
These new Superchargers have the potential to ease congestion and help eliminate the negative perceptions of slow EV charging.
