To provide a vehicle power conversion device capable of suppressing a connector unit installed in a storage case from receiving input of a load even when a vehicle collides with an object from the front.SOLUTION: A power control unit 30 which comprises a DCDC converter 303, a storage case 31 and a low-voltage connector unit 32 installed in the storage case 31 is mounted inside a front room FRM of a vehicle V. A first protrusion section 33 and a second protrusion section 34 are installed in a front side region of the storage case 31. The low-voltage connector unit 32 is installed at a position which is behind a first virtual line VL1 which is a common tangent line of the first protrusion section 33 and the second protrusion section 34 when viewed in a vertical direction and enables at least a portion of the low-voltage connector unit to be located between a first contact point P1 where the first virtual line VL1 comes into contact with the first protrusion section 33 and a second contact point P2 where the first virtual line VL1 comes into contact with the second protrusion section 34 in a left and right direction.SELECTED DRAWING: Figure 4

    【課題】車両の衝突等により車両前方から物体が衝突した場合でも、収容ケースに設けられたコネクタユニットに荷重が入力されることを抑制できる車両用電力変換装置を提供する。【解決手段】パワーコントロールユニット30は、DCDCコンバータ303と、収容ケース31と、収容ケース31に設けられた低電圧コネクタユニット32と、を備え、車両VのフロントルームFRM内に搭載される。収容ケース31の前側領域には、第1突出部33と第2突出部34とが設けられている。低電圧コネクタユニット32は、上下方向から見て、第1突出部33及び第2突出部34の共通接線である第1仮想線VL1よりも後方であって、少なくとも一部が、左右方向において、第1仮想線VL1の第1突出部33との接点である第1接点P1と、第1仮想線VL1の第2突出部34との接点である第2接点P2との間に位置するように設けられている。【選択図】図4
