Tesla is experimenting with charging capacities exceeding the current standard of 250 kW for its V4 and V3 Superchargers in the US, with some drivers reporting speeds just over 320 kW. This development comes as Tesla plans to open its charging network to other electric vehicle brands.
Electrek reports that Tesla is assessing the potential of its Supercharger V4 to charge at over 300 kW at select stations. These V4 Superchargers are still paired with V3 generation charging technology cabinets, leading to the designation of these stations as V3+ Superchargers.
Currently, Tesla EVs have a maximum charging capacity of 250 kW. However, as Tesla increasingly opens its charging stations to third-party brands—some of which feature vehicles with a DC charging capacity of up to 400 kW—the company is focusing on enhancing peak charging capacities.
Despite the global shift to V4 Superchargers, which support up to 350 kW, Tesla has continued to use V3 generation cabinets, limiting the utilization of V4’s full potential. Recent tests indicate that higher capacities are feasible. Tesla engineer Wes Morrill confirmed on X that the company is “running a trial on a few different V3+ stations (V3 cabinet + V4 charge post). This is not a bug, but it’s also not rolled out to all hardware capable stations.” Various users on X have posted photos showing Superchargers with peak charging capacities reaching around 320 kW.
As Tesla continues these tests, the possibility of significantly faster charging times for both Tesla and third-party electric vehicles could become a reality, further enhancing the appeal and convenience of Tesla’s Supercharger network.
