To provide a power supply unit capable of improving assembling properties in manufacturing.SOLUTION: A power supply unit 1 comprises a high-voltage battery 10, a front power supply box 20, a rear power supply box 30, and a high-voltage trunk line 40. The high-voltage battery 10 is a battery which has a plurality of interconnected battery cells 11a, 12a, and can accumulate electric power. The front power supply box 20 is an electric connection box which is assembled in front of the high-voltage battery 10 in a vehicle front-rear direction and can distribute electric power to a first load part 2. The rear power supply box 30 is an electric connection box which is assembled behind the high-voltage battery 10 in the vehicle front-rear direction, and can distribute electric power to a second load part 3. The high-voltage trunk line 40 is a rigid body which is assembled to the high-voltage battery 10, and extends over between the front power supply box 20 and the rear power supply box 30 to electrically connect the front power supply box 20 and the rear power supply box 30, and also stands by itself to maintain its shape.SELECTED DRAWING: Figure 1

    【課題】製造時の組み付け性を向上することができる電源ユニットを提供する。【解決手段】電源ユニット1は、高電圧バッテリ10と、フロント電源ボックス20と、リア電源ボックス30と、高圧幹線40とを備える。高電圧バッテリ10は、互いに接続された複数の電池セル11a、12aを有し、電力を蓄積可能なバッテリである。フロント電源ボックス20は、高電圧バッテリ10の車両前後方向の前側に組み付けられ、第1負荷部2に電力を分配可能な電気接続箱である。リア電源ボックス30は、高電圧バッテリ10の車両前後方向の後側に組み付けられ、第2負荷部3に電力を分配可能な電気接続箱である。高圧幹線40は、高電圧バッテリ10に組み付けられ、フロント電源ボックス20とリア電源ボックス30との間に渡って延在し、フロント電源ボックス20及びリア電源ボックス30を電気的に接続し、自立して形状を維持可能な剛体である。【選択図】図1
