WMG researchers convert used EV batteries into small off-grid ESS units

Green Car Congress

Researchers at WMG, University of Warwick, have repurposed end-of-life electric vehicle batteries as small energy storage systems (ESS) for off-grid locations in developing countries or isolated communities. We are now looking for support to allow these new units to be further developed and tested in remote or off grid locations.

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.

Liebherr converted this massive mining excavator to electric power

Baua Electric

For the first time in the company’s 40-year history, Liebherr have converted one of their R 9400 excavators from a conventional diesel to an electric powertrain. The converted R 9400 can be connected to a constant power source for energy, either directly to the grid or to a large scale BESS.

Rolls-Royce makes Duisburg container terminal climate-neutral with mtu hydrogen technology

Green Car Congress

It will not only set new standards in cargo handling, but also in climate-friendly energy supply. The hydrogen-powered mtu fuel cell solutions supply electrical power as soon as the public power grid reaches its limits, for example for the on-board power supply of ships berthed in the port or in the event of other load peaks.

ORNL demos 20 kW bi-directional wireless charging on UPS PHEV truck; 11" air gap, >92% efficiency

Green Car Congress

The system transferred electricity from the power grid to the vehicle battery terminals at more than 92% efficiency. ORNL’s bidirectional technology is fully compliant with grid power quality standards. The technology takes energy from the grid and converts it to direct current (DC) voltage. —Omer Onar.
