Electric vehicles are an increasingly common sight on Australian roads. Each one cuts carbon emissions by half compared to fossil fuel vehicles, but increases household electricity use by 50%.
This extra electricity demand could be a major strain on the grid unless the charging of vehicles is coordinated. But the large batteries in electric vehicles could also be enlisted to discharge power to the power grid when needed. The average electric vehicle battery stores more than two days worth of household electricity, so this could have a big effect.
