Patent number: 10921382Abstract: A management server obtains information on a use history of a battery assembly used in a vehicle. The management server calculates an amount of material deterioration Dm and an amount of high-rate deterioration Dh by using the information on the use history of the battery assembly. When a ratio Dm/Dh is higher than a threshold value Th, the management server generates first assembly information indicating selection of a cell highly resistant against material deterioration and a spacer highly resistant against material deterioration (a cell A and a spacer A). When the ratio Dm/Dh is lower than the threshold value Th, the management server generates second assembly information indicating selection of a cell highly resistant against high-rate deterioration and a spacer highly resistant against high-rate deterioration (a cell B and a spacer B).Type: GrantFiled: December 19, 2018Date of Patent: February 16, 2021Assignee: Toyota Jidosha Kabushiki KaishaInventor: Keita Komiyama
