BATTERY MANAGEMENT SYSTEM AND BATTERY MANAGEMENT METHOD

A battery management system includes an electronic device including a battery and a management server connected to the electronic device via a network. The electronic device transmits battery information, including information indicating the battery status, to the management server. The management server accumulates the battery information received from the electronic device in a storage. The management server predicts the current status of the battery of the electronic device based on the battery information of the electronic device, and transmits control information for the battery control of the electronic device to the electronic device based on a prediction result.
