Title:
始動可否判定装置および始動可否判定方法
Document Type and Number:
Japanese Patent JP5291132
Kind Code:
B2
Abstract:
To provide a start-up possibility determining apparatus and a start-up possibility determining method that can determine the possibility of an engine start-up accurately, even when a predetermined time has elapsed since an engine start-up in the past. It has a dynamic internal resistance measuring unit (control unit 10) that measures a dynamic internal resistance which is an internal resistance of the secondary battery while the engine is being started up by the starter motor, a static internal resistance measuring unit (control unit 10) that measures a static internal resistance which is an internal resistance of the secondary battery when the engine is stopped, and a determining unit (control unit 10) that determines possibility of a start-up of the engine by the secondary battery, based on a value obtained by a product of a ratio between a first static internal resistance measured by the static internal resistance measuring unit before or after a time of an engine start-up in the past and a second static internal resistance which by the static internal resistance measuring unit within a predetermined time since a current point of time and the dynamic internal resistance measured by the dynamic internal resistance measuring unit at the time of the engine start-up in the past.
