Claim 9:
10. A battery management system for electric vehicles, the battery management system comprising:
a plurality of electric vehicles each including a battery configured to supply electric power to a driving motor; and
an information processor configured to be able to communicate with the plurality of electric vehicles,
each of the plurality of electric vehicles comprising
circuitry configured to
detect a degradation state of the battery, and
detect a usage state of the battery,

the information processor comprising
a battery information storage configured to store information about the degradation state and the usage state of the battery of each of the plurality of electric vehicles, and
circuitry configured to
estimate a future degradation state of the battery of a specific electric vehicle among the plurality of electric vehicles, based on the information stored in the battery information storage, and
change control of a certain electric vehicle among the plurality of electric vehicles so as to delay degradation of the battery of the certain electric vehicle in a case where the future degradation state of the battery of the certain electric vehicle is estimated to be decreased by a predetermined amount or greater.
