To prevent a user from having a feeling of strangeness when confirming a reduction degree of full charge capacity of a storage battery device.SOLUTION: A vehicle diagnostic system 9 diagnoses a vehicle 1 mounted with a battery 13. The vehicle diagnostic system 9 comprises: an instrument panel 171 which displays a capacity maintenance factor Q of the battery 13; and an ECU 10 which calculates the capacity maintenance factor Q to be displayed on the instrument panel 171. The ECU 10 measures full charge capacity of the battery 13 every time external charging is completed and updates a capacity deterioration curve L representing a temporal change in the capacity maintenance factor Q on the basis of a measurement result. When a request is made for displaying the capacity maintenance factor Q on the instrument panel 171, the ECU 10 calculates the capacity maintenance factor Q at the time of the request by referring to the updated capacity deterioration curve L.SELECTED DRAWING: Figure 6

    【課題】ユーザが蓄電装置の満充電容量の低下度合いを確認する際の違和感を抑制する。【解決手段】車両診断システム9は、バッテリ13が搭載された車両1を診断する。車両診断システム9は、バッテリ13の容量維持率Qを表示するインパネ171と、インパネ171に表示するための容量維持率Qを算出するECU10とを備える。ECU10は、外部充電が完了する度にバッテリ13の満充電容量を測定し、その測定結果に基づいて、容量維持率Qを時間変化を表す容量劣化曲線Lを更新する。ECU10は、インパネ171への容量維持率Qの表示要求が発生した場合には、更新された容量劣化曲線Lを参照することで、表示要求の発生時における容量維持率Qを算出する。【選択図】図6
