Electric power storage apparatus

Abstract

A power storage device which receives an electric power from a high-voltage circuit of a vehicle is disposed, and reed switches are disposed in a circuit which switches a connection state of the power storage device. In the reed switches, the ON/OFF state is switched depending on the energization/deenergization and energization direction of a high-voltage bus bar which is placed at a proximal position. Moreover, a permanent magnet which generates a DC magnetic field to apply a bias in a specific direction is placed in the vicinity of the reed switches, and switching according to the energization direction is enabled. A movable permanent magnet is placed in the vicinity of the high-voltage bus bar, and the position of the permanent magnet is changed depending on the energization/deenergization and the energization direction.
