Ultra-fast EV truck charger hits 1 MW using just 500 kW grid power

Here's a novel approach to fast, high capacity charging that larger vehicles need. 

What researchers have done is to integrate several components, and a little bit of electronic management.  They created a system that can draw smaller amounts of power at any given time by using batteries and other pieces of tech to increase the amount of power and allow for speed an efficiency - at over 98% efficient it blows away current fast charging.
