1. A method for scheduling the replacement of wind turbine batteries, the method comprising:
- monitoring an air temperature of a location at which a battery is stored within a wind turbine;
determining with a controller a predicted lifetime for the battery based on the monitored air temperature; and
determining when to replace the battery based at least in part on the predicted lifetime.

Abstract
A method for scheduling the replacement of wind turbine batteries is disclosed. The method may include monitoring an air temperature of a location at which a battery is stored within a wind turbine, determining with a controller a predicted lifetime for the battery based on the air temperature and determining when to replace the battery based at least in part on the predicted lifetime.

13. A system for predicting the remaining lifetime of wind turbine batteries, the system comprising:
-
a battery configured to supply power to a component of the wind turbine; a temperature sensor configured to measure an air temperature of a location at which the battery is stored within the wind turbine; and a controller communicatively coupled to the temperature sensor, the controller being configured to determine a predicted lifetime for the battery based on the air temperature measurements provided by the temperature sensor. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A wind turbine comprising:
-
a tower; a nacelle mounted on the tower; a rotor coupled to the nacelle, the rotor including a hub and at least one rotor blade extending from the hub; a pitch adjustment mechanism configured to pitch the at least one rotor blade; a pitch battery configured to supply power to the pitch adjustment mechanism; a temperature sensor configured to measure an air temperature within the hub; and a controller communicatively coupled to the temperature sensor, the controller being configured to determine a predicted lifetime for the pitch battery based on the air temperature measurements provided by the temperature sensor.
