Future electric vehicles under the General Motors (GM) umbrella may soon be able to recharge their batteries with 290 km (180 miles) of driving range in less than 10 minutes, reports Bloomberg. The solid-state transformer-based Extreme Fast Charger (XFC) with 400 kW capacity is currently being developed by the Detroit-based automaker and one of its research partners, Delta Americas, as part of a three-year project.

The new XFC system – presumably using the SAE Combo Charging System (CCS) protocol as pictured above – is expected to offer grid-to-vehicle efficiency of up to 96.5%, and should give about 29 km of range per minute of charging. That’s three times quicker than Tesla’s 120 kW Supercharger system, which gives 9.6 km of driving range per minute. Porsche, on the other hand, claims that its Taycan electric sports car is capable of getting 20 km per minute, thanks to a 350 kW DC fast-charging system.

GM said the technology will be readied in 20 electric cars by 2023, all of which will be capable of rapid charging. “Everybody would like to replicate what we can do when we’re filling a tank of gasoline,” Abuelsamid said. “This is especially true for people who live in cities. It makes a lot of sense to have an EV in urban areas, but people who live there are least likely to have access to charging.”

Currently, Tesla says its Version 2 Supercharger stations (up to 145 kW, but vehicles are capped at 120 kW) are capable of replenishing the batteries of its EVs in 30 minutes. The company is planning on developing a 200 to 250 kW Version 3 Supercharger system soon, reports Electrek. GM’s Chevrolet Bolt however, requires 30 minutes of fast-charging (from a DC fast charge outlet, rated up to 90 kW) to get approximately 145 km of electric driving range.
