Abstract: 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.

Abstract: Controller of power storage pack performs communication for authentication with controller of an electric moving body according to the pattern of a current flowing through a power line in a state where power storage pack is mounted to electric moving body. Controller of power storage pack measures contact resistance between power storage pack and the electric moving body based on voltage of the power line on power storage pack side, voltage of the power line on the electric moving body side received from controller of the electric moving body, and current when communication for authentication is performed according to the pattern of a current flowing through the power line.

Abstract: A charging device wiredly transmits identification information to a power storage pack after the power storage pack is mounted. The power storage pack transmits via near-field communication a signal including the identification information received from the charging device. The charging device collates whether or not the identification information included in the received signal matches the identification information wiredly transmitted.

Abstract: A first power storage pack wiredly transmits identification information retained in the first power storage pack to a charging device when the first power storage pack is detached from an electric movable body. The charging device wiredly transmits the identification information received from the first power storage pack to a second power storage pack. The controller of the second power storage pack transmits via near-field communication a signal including the identification information received from the charging device. The electric movable body collates whether or not the identification information included in the received signal matches the identification information retained in the first power storage pack.

Abstract: A plurality of energy storage packs (51 to 58) supply a current to a plurality of motor driver (31 to 38) that drive a plurality of motors (21 to 28) mounted on moving object (1), respectively. Sub energy storage pack (59) supplies a current to at least one of a plurality of first current paths connecting the plurality of motor driver (31 to 38) and the plurality of energy storage packs (51 to 58), or pulls a current from at least one of the plurality of first current paths. Controller (70) controls the plurality of first switches (S11 to S18) and the plurality of second switches (S21 to S28) to adjust capacities between the plurality of energy storage packs (51 to 58).
