Electric cars have one large disadvantage when placed side-by-side with their traditional gas-powered rivals: the time it takes to refuel. General Motors has begun a new partnership with Delta Americas to develop a new technology which will charge its upcoming fleet of electric cars in record time.

General Motors said it is readying a fleet of 20 electric cars that will be capable of utilizing the newly developed chargers, enabling its vehicles to rapidly recharge their batteries and provide up to 180 miles of range in just 10 minutes. Its partner in the deal, Delta Americas, expects to have the final prototype of its Extreme Fast Charger (XFC) ready by 2020, and GM expects to have its fleet of vehicles ready only three years later, by 2023.

The new XFCs are set to outpace both Tesla's Superchargers, which can provide current-generation cars with up to 120-kilowatts of power, as well as Porsche's new 350-kW chargers, by providing an unheard of 400 kW of electricity to the vehicles. The new technology, developed with partner Delta Americas and sponsored by the U.S. Department of Energy, is able to provide a staggering 96.5 percent grid-to-vehicle efficiency, a three percent increase than current technology, partly thanks to the use of solid-state transformers.
