Abstract
Apparatus, systems, and methods are provided for determining remaining lifetime of a battery, such as a battery used to power a pitch drive system in a wind turbine. In one example implementation, a method can include controlling a discharge of the battery through a load. The method can include obtaining data indicative of a discharge voltage and a discharge current of the battery during discharge through the load. The method can include obtaining data indicative of a temperature associated with the battery during discharge through the load. The method can include determining data indicative of remaining lifetime of the battery as a function of the discharge voltage, discharge current, and the temperature. The method can include performing at least one control action based at least in part on the data indicative of remaining lifetime of the battery.
