Abstract: A used secondary battery module management system server manages a manufacture of a battery assembly. The server stores, in a memory, a correspondence relationship of each of secondary battery modules among identification information, ranks, and status information. The server extracts an available rank from the ranks in response to a rebuilding request for the battery assembly. The available rank is a rank in which the number of the secondary battery modules having the status information indicating that the secondary battery modules are available is equal to or larger than the number of the secondary battery modules required to constitute the battery assembly. The server receives, from an external terminal, the identification information on each of selection secondary battery modules having an identical rank.

Abstract: A vehicle battery assessment system includes an information acquisition unit, a learned model acquisition unit, a remaining life assessment unit, and an assessment result output unit. The information acquisition unit acquires at least vehicle information of a vehicle installed with a battery and usage history information of the battery. The learned model acquisition unit acquires a learned model that is created in advance by setting at least the vehicle information of the vehicle and the usage history information of the battery as explanatory variables, and the remaining life of the battery as a target variable. The remaining life assessment unit assesses the remaining life of the battery based on the vehicle information and the usage history information acquired by the information acquisition unit and the learned model. The assessment result output unit outputs the assessment result of the remaining life assessment unit.
