1. A method for preventing improper reuse of a traveling battery mounted on a vehicle, wherein the vehicle comprises
a battery module comprising battery cells that are stacked together,
an electronic control unit capable of controlling a voltage of each of the battery cells of the battery module, using an auxiliary battery as a drive power supply, and
an impact detection sensor configured to detect a magnitude of an impact to be applied to the vehicle,
the method for preventing reuse of a traveling battery comprising:
causing the electronic control unit to perform low-voltage-control exclusively on one of the battery cells that is selected in advance in a case where the magnitude of the impact detected by the impact detection sensor is a predetermined value or greater.
