Summary:A method of charging an auxiliary battery (for example an electric vehicle battery) with a local renewable power source and an external power source, comprising determining whether there is excess power generated by the local renewable power source (excess power may be power which is generated but not used by a local power consuming system, for example a home, building or factory), and if there is excess power then directing this to an auxiliary battery charger; if there is no excess power, then determining whether a minimum charge threshold of the auxiliary battery has been exceeded, if not then directing power from an external power source to the battery charger, if so then monitoring an external power price and if this is below a power price threshold then directing power from the external power source to the battery charger, and if the price is above the threshold then not directing power from the grid source to the charger.
