Degradation estimator for energy storage device, energy storage apparatus, input-output control device for energy storage device, and method for controlling input and output of energy storage device

摘要

It is an object of an embodiment to provide a degradation estimator for an energy storage device, configured to estimate degradation of the energy storage device, an energy storage apparatus, an input-output control device for the energy storage device, and a method for controlling input and output of the energy storage device. The embodiment includes estimating a temporary power decrease rate of the energy storage device in accordance with at least one of an average load, a maximum load, and a ΔSOC obtained from detected current of the energy storage device and detected temperature of the energy storage device.
