摘要： The embodiments of the present invention relate to a battery pack, detachably connected to an external device for charging or discharging. The battery pack includes a control module, and a communication terminal. The communication terminal is connected to the control module and the external device, and the control module detects the signal from the communication terminal to decide the pattern to determine the type of the external device. The battery pack further includes a state indication terminal, which is connected to the control module and the external device, and the control module detects at least one operating parameter of the battery, and generates a state parameter related to the operating parameter according to the operating parameter. The control module sends the state parameter to the outside by using the communication terminal, and the control module sends an abnormality signal to the outside by using both of the communication terminal and the state indication terminal. The embodiments of the present invention have the following beneficial effects: the battery pack may be used for an external device without a communication function and may also be used for an external device with the communication function with a plurality of usage scenarios and high universality. Further, the battery pack can not only receive a digital signal but also receive an analog signal by using only one port, to recognize types of external devices on different platforms with communication and without communication, with a small quantity of ports and a high degree of integration. In addition, the battery pack transmits to the outside by using two terminals, to doubly ensure communication, thereby preventing any abnormal communication terminal from causing damage to the use of the battery pack, and improving the use security.
