Tesla has announced the latest generation of its fast-charge DC Supercharger station, dubbed V3, boasting speeds of 250 kW. This more than doubles the automaker’s existing 120 kW cap via the V2 Supercharger network, although there are plans to upgrade those (about 12,000 units around the world) to support 145 kW fast-charging.

The focus of the day is V3 – the charging network is backed by a central one-megawatt power cabinet (its design is inspired by the brand’s industrial products) that supports 250 kW charging. Tesla says it enables 1,000 miles (1,600 km) per hour of charge when operating at peak efficiency.

Supercharger stations with V3’s new power electronics are designed to enable any owner to charge at the full power their battery can take, so owners will no longer have to split power with a vehicle in the opposing stall. With these technical improvements, the typical charging time at a V3 Supercharger will drop to around 15 minutes.

Tesla claims that a Model 3 Long Range would be able to gain 120 km of range with a charge time of just five minutes – the doubling of wattage will reduce charge time, and consequently customer waiting time by 50%.

On the software side of things, Tesla will roll out a new update called “On-Route Battery Warm-up” that warms the car’s battery to its optimum temperature while driving to the charging station. When all the parameters are met, this alone will be able to drop charge times by 25%.

The first V3 Beta site is now open in the Californian Bay Area, also known as the Tesla heartland. Tesla says the new charging station will be rolled out in the fourth quarter of 2019 throughout Asia Pacific.

While 250 kW certainly seems fast by today’s standards, Porsche’s ‘Turbo Charging’ solution promises a charging output of 320 kW, and this is to be made available once its all-electric Taycan model is launched. Conversely, the Ionity network in Europe will push out 350 kW, but only on vehicles that support it.

Other notable charging stations include FastCharge by BMW and Porsche – FastCharge boasts a 450 kW throughput, allowing 100 km of driving range with a charge time of just three minutes, or 15 minutes for a full charge. GM’s 400 kW solid-state transformer-based Extreme Fast Charger (XFC) is also in the works, and the technology will be readied in 20 of its electric cars by 2023.
