COMMUNICATION SYSTEM OF BATTERY PACK AND BATTERY PACK COMPRISING SAME

Provided are a communication system of a battery pack, and a battery pack including the communication system. According to an embodiment of the present disclosure, the communication system includes a transmitter configured to transmit a communication signal from the battery pack to an external device and a receiver configured to receive a communication signal from the external device, wherein the transmitter includes: a first transistor configured to perform a switching operation in response to a first communication signal output from a battery management system (BMS) of the battery pack; a second transistor configured to perform a switching operation in response to the switching operation of the first transistor; and a first diode configured to transmit the first communication signal to the external device in response to the switching operations of the first and second transistors, wherein the receiver includes: a third transistor configured to perform a switching operation in response to a second communication signal received from the external device; a fourth transistor configured to perform a switching operation in response to the switching operation of the third transistor; and a second diode configured to transmit the second communication signal to the BMS in response to the switching operations of the second and fourth transistors.
