PROBLEM TO BE SOLVED: To provide an electric power storage apparatus in which it is not required to supply a power source power from a low-voltage circuit in order to control the operation of the apparatus itself, and the low-voltage circuit can be isolated from a high-voltage circuit in the vicinity of a main battery.SOLUTION: There are provided a power storage device Cs that receives an electric power from a high-voltage circuit of a vehicle, and reed switches SW1 and SW2 in a circuit for switching a connection state of the power storage device Cs. In the reed switches SW1 and SW2, the ON/OFF state is switched according to the energization/de-energization and energization direction of a high-voltage bus bar 73 arranged at an adjacent position. Moreover, a permanent magnet that generates a DC magnetic field to apply a bias in a specific direction is disposed in the vicinity of the reed switches SW1 and SW2 so as to be capable of switching according to the energization direction. A movable permanent magnet is placed in the vicinity of the high-voltage bus bar 73, and the position of the permanent magnet is changed according to the energization/de-energization and the energization direction.SELECTED DRAWING: Figure 1
【課題】それ自身の制御動作のために低圧回路からの電源電力供給を必要とせず、メインバッテリの周辺で高圧回路と低圧回路とを分離できる蓄電装置を提供することにある。【解決手段】車両の高圧回路から電力を取り込んで蓄電する蓄電デバイスCsを設け、蓄電デバイスCsの接続状態を切り替える回路にリードスイッチSW1、SW2を設けた。リードスイッチSW1、SW2は、近接した位置に配置された高圧バスバー73の通電の有無や通電方向の違いに応じてオンオフ状態が切り替わる。更に、直流磁界を発生し特定方向のバイアスを与える永久磁石をリードスイッチSW1、SW2の近傍に配置して、通電方向の違いに応じた切替を可能にした。移動可能な永久磁石を高圧バスバー73の近傍に配置して、通電の有無と方向により永久磁石の位置が変化するように構成した。【選択図】図1
