BATTERY CONTROLLER, POWER STORAGE DEVICE, POWER STORAGE METHOD, AND PROGRAM

摘要

A battery controller (100) has: a measurement unit (110) that measures the voltage of a secondary battery; a control unit (120) that initiates a charging process in which charging is carried out until the voltage of the secondary battery reaches a second reference value, which is larger than a first reference value, when the voltage measured by the measurement unit (110) falls below the first reference value; and an adjustment unit (130) that receives the deterioration level of the secondary battery as first adjustment information, which serves as a reference for adjusting a hysterisis width, which is specified on the basis of the first reference value and the second reference value, and adjusts the hysteresis width on the basis of the first adjustment information that was received.
