Claim 2:
3. The energy storage system of claim 1, wherein the battery management system further comprises:
a first relay disposed between a positive electrode of the battery and a positive electrode of the power conditioning system;
a second relay disposed between a negative electrode of the battery and a negative electrode of the power conditioning system;
a first voltage sensor configured to detect a voltage of a first node between the first relay and the power conditioning system;
a second voltage sensor configured to detect a voltage of a second node between the first relay and the positive electrode of the battery; and
a microcomputer configured to control the first relay and the second relay, based on the voltage of the first node detected by the first voltage sensor and the voltage of the second node detected by the second voltage sensor.
