"With these significant technical improvements, we anticipate the typical charging time at a V3 Supercharger will drop to around 15 minutes". It includes entirely new hardware, including grid-connected batteries to act as a buffer to stabilize electrical loads (and reduce demand charges from utilities).
The electric vehicle firm's V3 Supercharger system is built on an entirely new architecture, with a 1MW power cabinet that can charge at up to 250kW per auto.
"This combination of higher peak power with V3, dedicated vehicle power allocation across Supercharger sites, and On-Route Battery Warmup enables customers to charge in half the time and Tesla to serve more than twice the number of customers per hour", the company said. It's called the V3 Supercharger, and it can support up to 250kW per auto, from a cabinet that's rated at 1MW.
The first V3 Beta site is now open in the Californian Bay Area, also known as the Tesla heartland. The Model Y SUV, due to be revealed next week, will likely also be able to use the system because it shares technical elements with the Model 3 saloon.
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.
The first non-beta V3 Superchargers will break ground next month in the U.S., with Europe and Asia-Pacific regions to follow in the fourth quarter of the year. Tesla has flirted with adding liquid-cooled cables to Superchargers in the past, but the rollout V3 is the first use of the new technology at scale.
Tesla shared news of the next-generation V3 Superchargers in a rare official blog post and the über quick video below.
The Supercharger network already has more than 12,000 charge points across North America, Europe, and Asia.
The company plans to increase the charging speeds of Model S and X via software updates in the coming months.
