Ericsson connected electric car project

Is described and displayed here, and it is a rather nice one. About using M2M/IoT technology to give drivers more control over charging, but also using smart grid technology to ensure that the cars charge themselves when electricity is cheapest. Assuming the price mechanism works correctly then this should be when loadings on the power grid are lowest, helping to even things out and thereby reduce emissions. And the cost-savings and additional control helps to make electric cars a bit more palatable.
