Tesla has recently introduced its upgraded V4 Superchargers, boasting a significant power boost that allows for charging vehicles at up to 500kW. The development of the V4 Superchargers has been an ongoing process, initially launched with a v3 cabinet that limited their overall capabilities.
While V3 and V4 Superchargers have been operating at 250kW for some time, Tesla recently conducted a public trial at select locations with Superchargers reaching power levels of 320kW. This increase in speed from the standard 250kW hinted at Tesla’s intention to enhance charging speeds.
With the introduction of the new V4 Supercharger cabinets, Tesla is set to surpass these previous numbers, although not all vehicles will be able to charge at the new 500kW speeds. It’s interesting to note that Tesla’s Superchargers initially started with a charging speed of just 90kW.
V4 Supercharger Cabinet
The V4 Supercharger, distinguishable by its lack of a hole in the center, has been in existence for some time, but it was running on V3 or V3+ cabinets. The arrival of the V4 cabinet marks a significant advancement.
The V4 Supercharger cabinet surpasses the 320kW V3+ capacity, delivering a massive 500kW charge to the Cybertruck—currently the only vehicle capable of utilizing this speed. This 500kW translates to an impressive 1,300 miles per hour of charge for the Cybertruck—nearly 2100 km/h.
These charging enhancements are partly due to the Cybertruck’s 800V system, indicating that not all older vehicles may benefit from these improvements. However, it is likely that the upcoming Model Y Juniper Refresh will feature an 800V system, drawing from Tesla’s experience with the Cybertruck.
If the new Model Y can achieve charging speeds comparable to the Cybertruck, it could significantly reduce charging times. With its lighter and more efficient design, the Model Y could achieve a much higher miles-per-hour charge rate at the same 500kW charging speed.
The new V4 chargers will accommodate vehicles with 400-volt and up to 1,000-volt architectures, offering substantial charging improvements for non-Tesla EVs that support 1,000 volts.
V4 Megacharger
In a brief video presentation, Tesla also showcased the updated V4 Megacharger designed for the Tesla Semi. The new MCS system can deliver up to 1.2 Megawatts, or 1,200 KW, via the MCS connector for the Tesla Semi and its large battery pack.
This enhancement for the Semi is poised to have a significant impact, making it an attractive option for companies engaged in short to medium-haul trucking, which accounts for nearly 90% of trucking activities in North America.
V4 Supercharger Rollout
The deployment of V4 Superchargers is scheduled to commence early next year, with initial sites already undergoing permitting processes. Notably, Tesla’s new V4 cabinet has streamlined the Superchargers’ design even further.
The V4 cabinet can power 8 posts, doubling the capacity of the V3 cabinet. With a smaller footprint and reduced complexity, installations can be completed more quickly, leading to the rollout of more V4 sites at a faster pace.
These new Superchargers have the potential to alleviate congestion and address concerns regarding slow EV charging, offering a more efficient and convenient charging experience for electric vehicle owners.
