A secondary battery state management system of the present invention includes: a battery charger that charges a secondary battery; and a storage server that stores electrical characteristics information which is information that indicates the electrical characteristics during charging of the secondary battery. An electrical characteristics measuring means measures the electrical characteristics during charging. A measurement information storing means stores the history of the measured electrical characteristics information for each secondary battery. A battery state determining means compares the electrical characteristics information of the secondary battery being measured by the electrical characteristics measuring means with the electrical characteristics information of the same secondary battery stored in the measurement information storing means, and determines the state of the secondary battery.
