Abstract
A battery controller and method for controlling a battery include training parameters for a battery capacity prediction model based usage of similar batteries and capacity information for the respective similar batteries. The model characterizes a capacity decay rate. 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 is controlled based on the predicted future battery capacity.
