To provide a cooling structure of a vehicle battery unit capable of improving space efficiency in a battery case while protecting a supply pipe and a discharge pipe from a load at the time of vehicle side collision.SOLUTION: A supply pipe 65 housed in a battery case 62 and introducing a refrigerant from the outside of a battery case 62 to a battery cooling portion 63, includes a first supply piping portion 651 that passes between a battery module 61 located on one side and an electrical junction box 64, and a second supply piping portion 652 passing between two battery modules. A discharge pipe 66 housed in the battery case 62 and discharging a refrigerant from the battery cooling portion 63 to the outside of the battery case 62, includes a first discharge piping portion 661 that passes between the battery module 61 located on the other side and the electrical junction box 64, and a second discharge piping portion 662 that passes between the two battery modules.SELECTED DRAWING: Figure 3

    【課題】供給配管及び排出配管を車両側突時の荷重から保護しつつ、バッテリケース内のスペース効率を向上させることができる車両用バッテリユニットの冷却構造を提供する。【解決手段】バッテリケース62に収容され、バッテリケース62の外部からバッテリ冷却部63へ冷媒を導入する供給配管65は、一方側に位置するバッテリモジュール61と電気接続箱64との間を通る第1供給配管部651と、2つのバッテリモジュール間を通る第2供給配管部652と、を備える。バッテリケース62に収容され、バッテリ冷却部63からバッテリケース62の外部へ冷媒を排出する排出配管66は、他方側に位置するバッテリモジュール61と電気接続箱64との間を通る第1排出配管部661と、2つのバッテリモジュール間を通る第2排出配管部662と、を備える。【選択図】図3
