Because the rollout requires new hardware, Tesla says that it will help satisfy owners by increasing the charge rate on its existing Supercharger v2 infrastructure by about 20 percent. Using a Model 3 Long Range as an example, the vehicle can gain 75 miles of range in just five minutes, with a per-hour charge rate of up to 1,000 miles (were the auto able to hold such a charge). It's called the V3 Supercharger, and it can support up to 250kW per auto, from a cabinet that's rated at 1MW.
To make better use of the Supercharger network, Tesla says it will also update its cars with a new feature that begins to prewarm their batteries when they approach a Supercharger, similar to the prewarming that occurs in some models when you use Ludicrous mode.
In more practical terms, Tesla says this will add up to 75 miles of range in just 5 minutes, more than enough for an average day's commuting in less time than it would take you to run in and use the restroom.
"Supercharger stations with V3's new power electronics are created to enable any owner to charge at the full power their battery can take - no more splitting power with a vehicle in the stall next to you", the company says.
Through that system and the V3 Superchargers, Tesla estimates that a typical charging time at one of the units will drop to 15 minutes. 145 kW is the charging rate of a current shared pair of Tesla's Superchargers, so the fix seems to be a simple software unlocking of the max speed of a single vehicle charging on a shared pair.
Tesla says that it has 12,000 Superchargers across North America, Europe, and Asia-and that 99 percent of the US population is covered by the charging network.
The other benefit is that vehicle owners will get the full 250 kw if their batteries can handle it, as there is no more power splitting with vehicles in the next stall. After rolling out in North America, the technology will reach Europe and the Asia-Pacific region in the fourth quarter, the company said. Tesla specifically mentions this in 2019.7.11's release notes.
