Abstract: The server acquires first data concerning a load applied to a body of an electric mobile apparatus, acquires second data concerning the performance of a storage battery mounted on the mobile apparatus, calculates a remaining lifetime of the body on the basis of the first data, calculates a remaining lifetime of the battery on the basis of the second data, compares the remaining lifetime of the body with the remaining lifetime of the storage battery, and instructs at least one of an activation of an unused function and an enhancement of a used function among a plurality of functions consuming the electric power of the mobile apparatus when the remaining lifetime of the body is shorter than the remaining lifetime of the storage battery.

Abstract: In a battery abnormality detection system, a data acquirer acquires a current flowing through a battery and a temperature of the battery. A determiner determines presence or absence of abnormal heat generation of the battery based on a relation between an amount of the current flowing through the battery in a certain period and a temperature rise of the battery in the certain period. The determiner determines the presence or absence of the abnormal heat generation of the battery based on the current and the temperature of the battery in a charging period in which the temperature of the battery exceeds a set temperature.

Abstract: In an indication detection system, a battery data acquisition unit is configured to acquire battery data including current data, the current data being obtained by periodically measuring a current flowing through a battery pack. A determination unit is configured to, when the current data in a charge period of charging the battery pack by a charger include a section temporarily having a current value of zero and an integrated value of current in the charge period including the section temporarily having the current value of zero is larger than at least one of an integrated value of current in a discharge period immediately before the charge period and an integrated value of current in a discharge period immediately after the charge period, determine that the occurrence of the section having the current value of zero is an indication of the battery pack becoming unusable.

Abstract: In a sign detection system, a battery data acquisition unit acquires battery data including current data obtained by periodically measuring a current flowing through a battery pack. When the current data in a period of charging the battery pack by a charger include a section temporarily having a current value of zero, a determination unit determines that the occurrence of the section having the current value of zero is a sign of unavailability of the battery pack.
