Battery management
Abstract:
The invention provides a method and apparatus for managing a battery comprising a plurality of series connected cells. The battery comprises a plurality of series connected statically balanced cells. The battery is arranged so that a substantially identical load is imposed on all of the cells, in use in order to maintain the balance. A battery charging controller is used for controlling the charging of the battery as is arranged to terminate charging prior to the cells reaching their maximum state of charge. The invention also provides a modified charging regime which controls individual cell voltage to avoid any single cell exceeding a desired voltage.
