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.

Study finds Dutch EV drivers would prefer not to participate in V2G with current charging times; opposite true with fast charging

Green Car Congress

According to a new study by researchers from Delft University of Technology, in the context of current recharging time, Dutch EV drivers in general prefer not to participate in “vehicle-to-grid” (V2G) contracts, while the opposite is true in the context of fast recharging. The final sample contains 148 respondents.

Hawaii study finds vehicle-to-grid discharge detrimental to EV batteries

Green Car Congress

Results of a study by a team at the Hawaii Natural Energy Institute, SOEST, University of Hawaii at Manoa, suggest that the additional cycling to discharge vehicle batteries to the power grid in a vehicle-to-grid (V2G) scenario, even at constant power, is detrimental to EV battery cell performance. 2017.05.015.

RMIT researchers demonstrate working rechargeable proton battery

Green Car Congress

Researchers at Australia’s RMIT University have demonstrated for the first time a working rechargeable “proton battery”. The rechargeable battery is environmentally friendly, and has the potential, with further development, to store more energy than currently-available lithium ion batteries. Earlier post.)

Univ. of Missouri team progressing with convection battery; enabling rechargeable lithium-metal batteries

Green Car Congress

Researchers at the University of Missouri led by Prof. The technology allows lithium-metal batteries to be recharged without the dendrite failure (short circuit) that has prevented rechargeable lithium-metal batteries from being commercially viable. Lower mass often translates to lower costs. Source: Dr. Galen Suppes.

Royal Academy of Engineering Report Says EV Success Depends on Low-Carbon Electricity, Universal Broadband Provision and Smart Grids

Green Car Congress

The introduction of electric vehicles on a large scale in the UK can only have a beneficial effect on CO 2 emissions if low-carbon electricity, universal broadband provision and smart grids are in place to support the transition, according to a new report published by the UK Royal Academy of Engineering.

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.
