Considering that the first detection line 31 and the second detection line 32 are more, the integrated circuit 33 may employ two standard integrated circuits 33 (because the number of electronic switches of each integrated circuit is only 4, such as 5 batteries or more, and more integrated circuits are required), as shown in fig. 3.
In the use of the present utility model,
when the battery box fails, if the battery box cannot output electricity to the electric tool, cannot be charged and the like, the detection switch 6 can be pressed down, so that the problem of which battery 2 in the battery box is automatically identified, the battery 2 is rapidly judged and replaced, and at the moment, the battery box is opened to replace the problem battery.
