DISCHARGE START TIME DETERMINATION SYSTEM FOR ELECTRICITY STORAGE DEVICE AND DISCHARGE START TIME DETERMINATION METHOD FOR ELECTRICITY STORAGE DEVICE

摘要

The system for determining the discharge start time of the battery (2) includes a prediction means (61) for predicting a power generation amount and a power consumption amount of the solar cell panel (1), a power price database (53) A first comparison means (621) for comparing the required amount of discharge with the dischargeable capacity, and a second comparison means (621) for comparing the required discharge amount with the dischargeable capacity when the required amount at the time of high- And a discharge start time determining means (63) for setting any one of the time from the first time to the second time before the discharge start time.
