Abstract
A battery controller and method for controlling a battery include training parameters for a battery capacity prediction model based on usage pattern information that correlates usage of similar batteries with capacity information for the respective similar batteries. The model characterizes a capacity decay rate in accordance with a present value of the battery capacity. Future battery capacity is predicted for a battery under control based on the battery capacity prediction model and a present value of the battery capacity. One or more operational parameters of the battery under control are controlled based on the predicted future battery capacity to extend the battery's usable lifetime.
