A reference discharge production unit produces a reference discharge amount based on statistics about the discharge amount of the battery with the plurality of use units. A lifetime charge number obtaining unit(20e) obtains the charge number according to the lifetime of the battery based on the reference discharge amount. A data storing unit stores data about the relation between the reference discharge amount and the charge number.</p> |
