  "textContent": "A battery system according to an embodiment of the present invention may include a plurality of battery management systems (BMSs) connected in a daisy chain manner. Here, each of the BMSs may include: a control unit; and a photo relay that transmits a control signal for identifier (ID) allocation, which is input from a signal input terminal, to the control unit in an optical transmission manner. In addition, when the control unit receives the control signal from the photo relay, the control unit may allocate its own ID according to a predefined ID allocation protocol, and transmit the control signal to a signal input terminal of a next BMS through a signal output terminal.",
