1. A method for managing demand within a power network, comprisingobtaining status information regarding a plurality of client devices, the status information including information defining for each client device a charging interval and information defining a discharge rate for each client device during the charging interval;
- obtaining grid information regarding a power network, the grid information defining predicted energy costs for a plurality of charging periods within the charging interval;
deriving, based on the status information and the grid information, a charging scheme for each client device to be applied during the charging interval, wherein the charging scheme comprises instructions regarding times during the charging interval the client device should and should not charge; and
transmitting instructions to the client devices in accordance with the charging scheme during the charging interval.

Abstract
A device and method are presented by which a client device can be charged according to a charging scheme which takes accounted of predicted energy cost over a charging interval and the predicted discharge rate of the client device in that time. Multiple client devices can be controlled to optimise the times at which they are charged from the power network in order to minimise energy costs.
