A method for selecting power sources including batteries, fuel cells and solar cells is developed. It is based on matching the physical and performance characteristics of power sources, such as weight, volume, capacity, voltage and cost, to the requirements of the given task. Physical and performance characteristics are collated from manufacturers' data and a database is built using advanced selection software. This allows the construction of performance maps in terms of voltage, maximum current, mass energy density, volume energy density and cost, giving a systematic comparison of different kinds of power sources. The use of the method as a preliminary design tool is demonstrated in a case study on the selection of batteries for mobile phones.
