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.

Mobilize launching first commercial V2G service starting in 2024 with Renault 5; France, Germany and UK initially

Green Car Congress

In addition to reinjecting electricity into the power grid, the bidirectional charger supports a vehicle-to-load (V2L) function for powering electrical appliances directly from the car. A smartphone app used to program bidirectional charging, simply by setting the time when the vehicle is going to be used next and the desired battery level.

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

Cars That Think

In 2001, a team of engineers at a then-obscure R&D company called AC Propulsion quietly began a groundbreaking experiment. 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.

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.

Volkswagen bringing 48V MHEV to eight-generation Golf

Green Car Congress

While the Plug-in Hybrid (PHEV) charges the battery via the grid with a plug, the MHEV does not have a battery that can be recharged via a plug, but is equipped with a 48V belt starter generator. The starter generator is coupled to the combustion engine. A DC/DC converter supplies the conventional 12V grid with voltage.
