A battery management system for electric vehicles includes electric vehicles each including a battery to supply electric power to a driving motor and an information processor to communicate with the electric vehicles. The electric vehicles each include a degradation state detector to detect a degradation state of the battery, and a usage state detector to detect a usage state of the battery. The information processor include a battery information storage to store information about the degradation state and the usage state of the battery, a degradation state estimator to estimate a future degradation state of the battery of a specific electric vehicle, based on the information stored in the battery information storage, and a vehicle control changer to change control of a certain electric vehicle to delay degradation of the battery if the future degradation state of the battery is estimated to deteriorate by a predetermined amount or greater.
