Claim 0:
1. 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
a degradation state detector configured to detect a degradation state of the battery, and
a usage state detector configured to 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,
a degradation state estimator 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
a vehicle control changer configured to 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 degradation state estimator has estimated that the future degradation state of the battery of the certain electric vehicle is to be decreased by a predetermined amount or greater.
