METHOD AND SYSTEM FOR ESTIMATING THE LIFETIME OF A BATTERY OF AN ENERGY BACKUP SYSTEM OF A WIND TURBINE

摘要

A method (300, 1600) and a system (400, 500, 600) for estimating the lifetime of a battery of an energy backup system (200) of a wind turbine (100) are provided. The method includes determining battery information characterizing a current battery state or at least one battery state of the past (302), and estimating the lifetime of the battery in dependence on the determined battery information (304).
