Abstract
The present invention is a power storage service system including: quantitatively grasping the time leading up to the expression of the abnormality; capable determining possible or impossible of avoiding stopping of the function of the assembled battery system. According to the invention, a maintenance operator and a maintenance service supplier of the assembled battery system have a time margin to plan a response schedule and to prepare responding, and it can reduce the cost of responding to the maintenance by reducing and optimizing the number of response. One aspect of the present invention is a power storage service system configured to control a power system using an assembled battery system including a plurality of unit cells, the power storage service system including: a first measurer configured to measure a self-discharge current difference among the plurality of the unit cells; and a second measurer configured to obtain a residual time of the assembled battery using the self-discharge current difference measured by the first measurer.
