BATTERY MANAGEMENT METHOD, STORAGE CONTROLLER, AND SERVER

In a battery management method of managing battery packs by an external storage, the battery packs are detachably mounted on respective vehicle bodies of movable bodies. The method includes receiving battery identification information from each battery pack by processing circuitry fixed to the vehicle body; storing the received battery identification information in a vehicle body-side memory fixed to the vehicle body; associating state history information with the battery identification information and storing the state history information in the vehicle body-side memory by the processing circuitry, the state history information indicating a history of a state of a battery of the battery pack while the battery pack is mounted on the vehicle body; and associating the state history information, stored in the vehicle body-side memory, with the battery identification information and transmitting the state history information from the movable body to the external storage by the processing circuitry.
