1. A system comprising:
at least one processor;
a communication section receiving, using the at least one processor, from an external apparatus that can connect to a battery pack, via a communication network, battery pack information including first identification information for identifying an identity of the battery pack and second identification information for identifying an electric apparatus that is connected to the battery pack and utilizes electrical power accumulated in the battery pack;
a storage section storing, using the at least one processor, a discount rate table that indicates a relationship between a number of times any battery pack has been replaced among a plurality of electric apparatuses and a discount rate on a use fee of the any battery pack and storing the battery pack information received by the communication section, wherein the relationship indicates that the discount rate is higher when the number of times is higher; and
an identification section referring to, using the at least one processor, the storage section, identifying a number of times the battery pack has been replaced among a plurality of electric apparatuses based on the battery pack information, and identifying the discount rate of the battery pack based on the identified number of times and the discount rate table, wherein
in response to the external apparatus is powered on, the external apparatus obtains the first identification information from the battery pack and the second identification information from a memory of the external apparatus and repeats calculating a degradation level of the battery pack and updating the degradation level stored in the battery pack with the calculated degradation level until the external apparatus is powered off, and
in response to the external apparatus is powered off, the communication section receives, using the at least one processor, the battery pack information including the first identification information, the second identification information, and the updated degradation level.
