Abstract
The invention provides a power storage battery (10) comprising a multiplicity of interconnected identical electrochemical power storage cells (11) whose internal resistance varies with their temperature. The cells are interconnected into a plurality of groups (16, 18, 31) with each group comprising a plurality of the cells, at least some of which are connected in series. The groups are connected in parallel and the battery in use has a temperature profile whereby at least some of its cells are at different temperatures from one another. The cells of each group are located and interconnected so that, in use, each group has substantially the same internal resistance as any other group.
