Abstract: In a power storage pack, a power storage unit supplies electric power to an electric mobile body. A wireless communication unit performs short-range wireless communication. A notification unit presents, to a user of a mobile terminal device, a tentative notification of a verification code that is to be used in the process of exchanging an encryption key that is to be used for the short-range wireless communication with the mobile terminal device. The notification unit may include a remaining capacity display for the power storage unit.

Abstract: In impact detection device to be mounted on power storage pack, an impact detection circuit compares detection values of three axes output from a three-axis accelerometer sensor with thresholds set to different values according to mechanical characteristics of power storage pack, and detects an impact outside an allowable range. For example, power storage pack includes wound cylindrical cells, and a threshold of an axis in a direction along a winding axis may be set to a value smaller in absolute value than thresholds of other two axes.

Abstract: In an electric mobile vehicle to which a power storage pack is attached, a controller obtains, from the power storage pack via wired or wireless communication, a verification code that is to be used in a process of exchanging an encryption key that is to be used for short-range wireless communication between the power storage pack and a portable terminal device. A notification unit presents, to a user of the portable terminal device, a tentative notification of the verification code obtained from the power storage pack.

Abstract: In a power storage pack, a power storage unit feeds electric power to an electric moving body. A controller superimposes a current pattern representing identification information of the power storage pack on electric power to be supplied to electric moving body. The controller generates a current pattern with current values of a plurality of levels other than zero level. The controller may superimpose a current pattern on electric power supplied to an electric moving body through a precharge circuit.
