To simplify a structure of a refrigerant passage for supplying a refrigerant into a refrigerant jacket of a two-story battery case.SOLUTION: A case bottom wall of a first battery case 31 is divided into a left case bottom wall 33b and a right case bottom wall 33c, a first refrigerant jacket includes a left first refrigerant jacket 36A formed on a left case bottom wall 33b and a right first refrigerant jacket 36B formed on a right case bottom wall 33c, a left end of the left first refrigerant jacket 36A communicates with a left end of a second refrigerant jacket 47 via a left refrigerant passage 33e, and a right end of a right first refrigerant jacket 36B communicates with a right end of the second refrigerant jacket 47 via a right refrigerant passage 33g. Thus, even if a refrigerant jacket has a second-story structure and refrigerant jackets 36A, 36B on a first floor are divided into right and left, these refrigerant jackets 36A, 36B, 47 can be connected via a continuous refrigerant passage, so that high cooling performance can be obtained while minimizing the number of components to simplify the structure.SELECTED DRAWING: Figure 4

    【課題】 二階建てのバッテリケースの冷媒ジャケットに冷媒を供給する冷媒通路の構造を簡素化する。【解決手段】 第1バッテリケース31のケース底壁は、左ケース底壁33bおよび右ケース底壁33cに分割されており、第1冷媒ジャケットは、左ケース底壁33bに形成された左第1冷媒ジャケット36Aと、右ケース底壁33cに形成された右第1冷媒ジャケット36Bとからなり、左第1冷媒ジャケット36Aの左端と第2冷媒ジャケット47の左端とは左冷媒通路33eで連通し、右第1冷媒ジャケット36Bの右端と第2冷媒ジャケット47の右端とは右冷媒通路33gで連通するので、冷媒ジャケットが二階建て構造であり、かつ一階の冷媒ジャケット36A,36Bが左右に分割されている場合であっても、それらの冷媒ジャケット36A,36B,47を一続きの冷媒通路で接続することができ、部品点数を最小限に抑えて構造を簡素化しながら高い冷却性能を得ることができる。【選択図】 図4
