The positive electrode of the battery core pack 20 is electrically connected to the positive terminal 12 through a first conductive member 24, and the negative electrode of the battery core pack 20 is electrically connected to the negative terminal 14 through a second conductive member 26, so as to output power from the positive terminal 12 and the negative terminal 14. In this embodiment, one of the first and second conductive members 24,26 includes a switch element 262, and the other includes a fuse 242, and more specifically, the positive electrode of the battery core pack 20 is electrically connected to the positive terminal 12 through the fuse 242, the negative electrode of the battery core pack 20 is electrically connected to the negative terminal 14 through the switch element 262, and the switch element 262 can be controlled to be turned on or off. In practice, the positions of the fuse 242 and the switch element 262 may be interchanged, or only one of them may be provided, or neither of them may be provided.
The encoder 30 can generate one of a plurality of encoding configurations, the encoder 30 has an encoding portion 32 and an operating portion 34, the encoding portion 32 is used for generating one of the encoding configurations corresponding to the operation of the operating portion 34, the operating portion 34 is used for a person to manually set one of the encoding configurations of the encoder 30, the encoding portion 32 is located in the casing 10, and the operating portion 34 protrudes out of the casing 10. In the present embodiment, the encoder 30 is exemplified by a coding switch having four output pins, the coding configurations are 16 configurations, the operating portion 34 includes a rotating rod 342 and a knob 344 connected to the rotating rod 342, the rotating rod 342 can rotate among a plurality of rotation angles, and each rotation angle corresponds to the coding portion 32 to generate one coding configuration.
Referring to fig. 2, in order to allow the operator to recognize the generated code configuration, a plurality of code marks 18 are disposed on the housing 10 and located at the periphery of the operating portion 34 (i.e. 1 to 16 and the scale in fig. 2), and each code mark 18 corresponds to the rotation angle of the rotating rod 342. The knob 344 is provided with a pointer 346, and the knob 344 is rotated by a person to drive the pointer 346 to correspond to one of the code marks 18. In practice, the indicator 346 may be disposed at any position on the operation portion 34, and it is important that the rotating rod 342 is rotated to correspond to one of the code marks 18.
The battery pack monitoring unit 40 is electrically connected to the battery core pack 20 and the encoding portion 32 of the encoder 30, in this embodiment, the battery pack monitoring unit 40 includes a detecting module 42 and a microcontroller 44, the detecting module 42 is electrically connected to the battery core pack 20 to detect the state of the battery core pack 20, and the detected state includes at least one of the total voltage, the current, the voltage and the temperature of each battery core of the battery core pack 20. The microcontroller 44 is electrically connected to the detection module 42, the encoder 30 and the switch element 262, and the microcontroller 44 is further connected to the socket terminal 16 through a communication interface 46, wherein the communication interface 46 is used for converting the signal output by the microcontroller 44 into a signal of a BUS, such as a signal of a CAN-BUS.

In addition, the battery pack monitoring unit 40 may further control the switch assembly 262 to be turned off, so that the battery core pack 20 stops outputting power to the positive terminal 12 and the negative terminal 14, so as to cut off the power output by the battery pack 100.
Thus, the status signal outputted by the battery pack 100 includes the identification code corresponding to the encoding configuration of the encoder 30 and the status of the battery pack 20. The operator can manually change the code configuration from the operation portion 34 of the encoder 30, and further change the identification code of the battery pack 100, so that the battery pack 100 of the present embodiment becomes a universal battery pack, that is, there is no need to set a unique identification code for the battery pack 100 when producing the battery pack 100.

When assembling the power system 1, a user can directly set the encoding configuration in the encoder 30 of each battery pack 100, and the encoding configuration can be conveniently adjusted by the user through the operation portion located outside the housing 10. After the code configuration of each battery pack 100 is set to be different (i.e. 1-16 in fig. 3), each battery pack 100 can transmit the status signal to the battery management device 200, and the battery management device 200 can determine which battery pack 100 the status signal is transmitted by after analyzing the received status signal.
It should be noted that, when any battery pack 100 needs to be replaced, the original battery pack 100 is taken down, a new battery pack 100 is replaced, and the encoding configuration of the encoder 30 of the new battery pack 100 is set to be the same as that of the original battery pack, so that the defect that the identification code needs to be rewritten in the commonly-used battery pack is effectively overcome.
