DECISION METHOD, DECISION DEVICE, PRESERVATION ASSISTANCE SYSTEM, AND COMPUTER PROGRAM

The invention provides a decision method, a decision device, a preservation assistance system, and a computer program. This decision method includes: determining whether measurement data pertaining to a plurality of power storage elements included in a system is periodically stored in a storage device; when the measurement data is determined as stored, determining, on the basis of the acquired measurement data, whether each of the plurality of power storage elements reaches the end of lifetime within a period corresponding to a standard use period at a prescribed temperature; and deciding that a power storage element determined as reaching the end of lifetime is required to be replaced. 本发明提供一种判断方法、判断装置、维护辅助系统以及计算机程序。在判断方法中，判断是否在存储装置中定期存储了与系统所包括的多个蓄电元件相关的测定数据，在判断为存储了测定数据的情况下，基于获取的测定数据，针对所述多个蓄电元件的每一个，判断在给定温度下在相当于标准使用期间的期间内是否达到寿命，针对判断为达到寿命的蓄电元件判断为需要更换。
