PROBLEM TO BE SOLVED: To provide a power supply control system, battery pack, body device and power supply control method, which safely prevent the generation of a large current caused by a short circuit of a power supply terminal. SOLUTION: The power supply control system is constituted of: the battery pack 40 having a power supply control terminal that controls the output or the non-output of a battery cell to the power supply terminal; and the body device having a body control terminal and a body power supply terminal which are connected to the power supply control terminal and the power supply terminal, respectively, at the mounting of the battery pack 40, and also having control circuits (54, 70 and 71) which feed control voltages to the body control terminal from an internal power supply 57 of the body device while the battery pack is not mounted, and output the control voltages by feeding power to the body power supply terminal in place of the internal power supply 57 by the mounting of the battery pack.
