POWER ESTIMATION DEVICE FOR ESTIMATING CHARGEABLE/DISCHARGEABLE POWER OF ELECTRIC STORAGE DEVICE, ELECTRIC STORAGE APPARATUS, AND METHOD OF ESTIMATING CHARGEABLE/DISCHARGEABLE POWER

摘要

A power estimation device for estimating at least one of chargeable power and dischargeable power of an electric storage device, the power estimation device includes a memory unit and a processing unit. The memory unit stores a reference power value. The processing unit is configured to perform: a condition determination process to determine whether a condition of the electric storage device is a voltage limit condition or a current limit condition; a first power estimation process to estimate chargeable/dischargeable power by multiplying the reference power value by a first correction factor if the condition of the electric storage device is the current limit condition; and a second power estimation process to estimate chargeable/dischargeable power by multiplying the reference power value by a second correction factor that is different from the first correction factor if the condition of the electric storage device is the voltage limit condition.
