step five: connecting a socket (3) arranged on a shell (1) to an external power supply, then clicking a switch (4) on the shell (1) to enable a motor (5) on the shell (1) to start working to move a sliding block (18) connected with the shell (1), paying attention to a prompting lamp (6) on the shell (1), immediately clicking the switch (4) clicked to close the motor (5) if the prompting lamp (6) is on, and thus finding out the condition of leakage of electricity on the surface, which is in contact with the sliding block (18), of the lithium battery pack to be detected;
step six: and clicking the switch (4) clicked in the step five to close the motor (5) used in the step five, then clicking another switch (4) on the shell (1), repeating the working process of the step five until all the surfaces of the lithium battery pack to be detected are subjected to detection work, and then releasing the electric connection between the socket (3) and an external power supply to finish the detection work.
