Abstract: A battery pack electrically comprising a temperature terminal and is configured such that when an external device is electrically connected to the battery pack, the device can detect the temperature of the battery pack, and the battery pack is further configured to receive a PWM signal from the external device when in the electrical connection state, and, on the basis of the PWM signal, determine the type and/or operating state of the external device. Also disclosed, a power tool system comprising the battery pack, as well as a communication system for the battery pack and the system. With the battery pack and the power tool system, it is possible to perform both a temperature sampling function and a function of identifying external device information only by a temperature terminal of the battery pack, thus same have the advantages of a simple and compact structure and low cost.

Abstract: A communication control unit for establishing a communication line between an electrical unit and a battery unit, wherein there is an electrical power transmission line between the electrical unit and the battery unit, the communication control unit being configured to: in response to determining that a communication interference occurs between the communication control unit and the electrical unit and/or the battery unit during a period when the electrical unit supplies electrical power to the battery unit or acquires electrical power from the battery unit, switch a first communication protocol currently used for communication between the communication control unit and the electrical unit and/or the battery unit to a second communication protocol, wherein the second communication protocol has a higher anti-interference capability than the first communication protocol.
