To provide an energization device which prevents a relay from being influenced by heat generated during travel.SOLUTION: An energization device comprises: a first relay DCRB which connects or disconnects a positive bus bar of a first power line connected to a power storage device and a positive bus bar of a second power line to which power is supplied from external power source; and a second relay DCRG which connects or disconnects a negative bus bar of the first power line and a negative bus bar of the second power line. The energization device includes a control device which switches off one of the first relay and the second relay when turning on the first relay and the second relay and performing external charging at a prescribed time when prescribed conditions are satisfied. The relay out of the first relay and the second relay which is turned off at the prescribed time is arranged far away from the path region which becomes a current path during traveling in comparison with the relay out of the first relay and the second relay which is turned on at the prescribed time.SELECTED DRAWING: Figure 2

    【課題】走行時に発生した熱がリレーに影響を与えることを抑制する通電装置を提供する。【解決手段】蓄電装置に接続される第1電力ラインの正極母線と、外部電源からの電力が供給される第2電力ラインの正極母線と、の接続および接続の解除を行なう第1リレーDCRBと、第1電力ラインの負極母線と、第2電力ラインの負極母線と、の接続および接続の解除を行なう第2リレーDCRGと、を備える通電装置であって、第1、第2リレーをオンにして外部充電を行なっている場合に所定条件が成立したときである所定時に、第1、第2リレーのうちの一方をオフにする制御装置を備え、第1、第2リレーのうち所定時にオフするリレーは、第1、第2リレーのうち所定時にオンするリレーに比して、走行時に電流の経路となる経路領域から遠い位置に設けられている。【選択図】図2
