Researchers developing DC micro smart grid for charging EV fleets; Li-ion, redox flow batteries and renewables

Green Car Congress

Up to 30 electric vehicles at a time can recharge in Fraunhofer IAO’s parking garage. The aim of charge@work is to design a micro smart grid (MSG) capable of supplying the EV fleet with electricity produced exclusively from renewable sources. The MSG is designed as a direct current (DC) grid. Click to enlarge.

UPA installs 500 kWh containerized Li-ion system from BYD for grid storage

Green Car Congress

BYD mega-watt-scale energy storage stations are installed in several locations in the US and are rated at a 91% AC-DC-AC round-trip-efficiency but have shown actual performance at this site as high as 95.3%—a AC-DC-AC efficiency shown to be as high as 94%, an industry benchmark high; DC to DC efficiency as high as 96%.

ANSI releases for public comment draft roadmap of standards and codes for EVs at scale

Green Car Congress

The roadmap’s primary focus is on light duty, on-road plug-in electric vehicles (PEVs) that are recharged via a connection to the electrical grid, as well as the supporting charging infrastructure needed to power them. Topics covered include standards to address high power DC charging; storage (i.e.,

IDTechEx: we need fast, reliable and ubiquitous public charging stations

Green Car Congress

IDTechEx forecasts that most of the new DC charging installations will be in the 100+ kW power classes. The Nevera’s 120 kWh, liquid-cooled battery uses an 800 V architecture which should be able to recharge from 0 to 80% SoC in 22 minutes, with the car supporting a peak charging power of 500 kW.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G. And EV owners would become entrepreneurs, selling electricity back to the grid. And indeed, that’s how promoters of vehicle-to-grid technology perceive the EV.

IDTechEx: Nio spearheading battery swapping expansion beyond China

Green Car Congress

However, IDTechEx believes that Europe will remain a charging-dominant region with a focus on DC fast charging deployment, and the number of swapping stations will remain small. This is a unique feature of battery swapping stations that could be exploited in the future to make them act as grid-support units.
