1. A battery management system, comprising:
a plurality of electric vehicles capable of travelling by driving a motor with an exchangeable battery;
a battery station capable of charging the battery by adjusting a charging speed; and
a management server connected to the plurality of electric vehicles and the battery station through a communication network,
wherein the management server quantitatively evaluates exchangeability of the battery stored in the battery station, on the basis of at least a distribution density of the plurality of electric vehicles and battery remaining amounts of the battery mounted on the plurality of electric vehicles, the distribution density of the plurality of electric vehicles and the battery remaining amounts being periodically transmitted from the plurality of electric vehicles,
the management server determines the charging speed of the battery of the battery station by the exchangeability of the battery which is evaluated on the basis of at least the distribution density of the plurality of electric vehicles and the battery remaining amounts of the battery which are periodically transmitted from the plurality of electric vehicles, and
the management server transmits control information relevant to the determined charging speed, to the battery station.
