Controller (12) of power storage pack (10) communicates with controller (32) of electric moving body (30) in a state where power storage pack (10) is mounted to the electric moving body. Communication wiring (Lc1) connects a node of power line (Lp1) on power source terminal (Tp) side relative to first switch (RYp) and controller (12) of power storage pack (10). Overvoltage protection circuit (19) turns off second switch (SWc) inserted into communication wiring (Lc1) upon detecting an overvoltage of power line (Lp1) during communication between controller (12) of power storage pack (10) and controller (32) of the electric moving body.
