Abstract

An architecture for organising information in a battery monitoring system, the architecture having a hierarchy of levels including a first level containing information relating to battery variables; a second level containing information relating to analysis of real-time or trend behaviour of the battery variables, and a third level containing user information relating to user and/or maintenance parameters, the user information being derived from the first and/or second level information. A method of estimating the condition of one or more cells, the method including periodically measuring the capacity of the cells, wherein the type of measurement and/or the period between measurements is dependent upon the state of health of the cell or cells and/or the result of a previous test.
