Claim 13:
14. The switching module according to claim 13, wherein
in the first determination process, the determiner obtains the first voltage value and the second voltage value to repetitively determine whether the first differential value of the first voltage value and the second voltage value is greater than a second voltage threshold value, which is greater than the first voltage threshold value, and then executes the second determination process when successively determining that the first differential value is greater than the second voltage threshold value for a number of times that is greater than or equal to a third number threshold value that is less than the second number threshold value; and
in the second determination process, the determiner obtains the first voltage value and the second voltage value to repetitively determine whether the second differential value of the first voltage value and the second voltage value is less than or equal to the second voltage threshold value, and determines that the first bidirectional switch is functioning normally when successively determining that the second differential value is greater than the second voltage threshold value for a number of times that is greater than or equal to the third number threshold value.
