To provide a battery resistance measuring device, a vehicle, and a battery resistance measuring method capable of simply and accurately measuring the electric resistance of a battery.SOLUTION: A battery resistance measuring device that measures electrical resistance of a target battery includes a determination portion and a measurement portion. The determination portion is configured to determine whether the target battery has switched from a charging state to a discharging state in which power greater than supplied power is output while receiving the supplied power, on the basis of whether a predetermined condition is satisfied. The measurement portion is configured to start measuring the electrical resistance of the target battery at a timing when the determination unit determines that the target battery has switched from the charged state to the discharged state.SELECTED DRAWING: Figure 13
【課題】簡単かつ的確に電池の電気抵抗を測定できる電池抵抗測定装置、車両、及び電池抵抗測定方法を提供する。【解決手段】電池抵抗測定装置が、対象電池の電気抵抗を測定する電池抵抗測定装置であって、判断部及び測定部を含む。判断部は、所定の条件が成立したか否かに基づいて、対象電池が、充電状態から、電力の供給を受けながら、供給される電力よりも大きい電力を出力する放電状態に切り替わったか否かを判断するように構成される。測定部は、対象電池が充電状態から上記の放電状態に切り替わったと判断部が判断したタイミングで、対象電池の電気抵抗の測定を開始するように構成される。【選択図】図13
