Abstract: A power supply module to be installed on a drive unit in a removable manner includes: a lithium ion capacitor unit that contains at least one lithium ion capacitor cell; a power supply line for supplying power to the drive unit; a first switch unit provided on the power supply line; a protective circuit constituted so that it turns off the first switch based on the voltage of the lithium ion capacitor; and a second switch unit that has at least one switching element, provided between the lithium ion capacitor unit and the protective circuit. The second switch unit is constituted so that it turns on based on a control signal input from the drive unit while the power supply module is installed on the drive unit, and turns off while the control signal is not input. The power supply can suppress leak current from a lithium ion capacitor.

Abstract: A cover is made for electric storage device including: a container which is placed on one principal face of a board having a first through hole for a terminal and a second through hole for a terminal, and which has a first end face orthogonal to the one principal face; and a positive-electrode terminal and a negative-electrode terminal, both projecting from the first end face and then being bent, with their ends penetrating through the first through hole for a terminal and the second through hole for a terminal, respectively, and led out from the other principal face of the board. The first cover is placed on the one principal face side of the board, and forms, together with the first end face and the first principal face, a first housing part for terminals that houses the positive-electrode terminal and the negative-electrode terminal.
