  • Patent number: 10451683
    Abstract: To accurately determine whether an engine can be started while accurately detecting a degree of deterioration of a secondary battery, in a secondary battery state detecting device detecting a state of a secondary battery mounted on a vehicle, a measurement unit measures a value of an internal resistance of the secondary battery at an engine stop time. An estimation unit estimates a value of a diffusion resistance resulting from diffusion of an ion generated at an electrolytic solution of the secondary battery by supplying electric power to a starter motor at a starting time of the engine. A calculation unit calculates a starting voltage being a voltage for the starting of the engine from a resistance value obtained by adding the value of the diffusion resistance estimated by the estimation unit to the value of the internal resistance measured by the measurement unit.
