仕切り板３２は、本実施の形態では、底壁２８および一方の第１側壁部３００２に設けられている。
仕切り板３２は、底壁２８に載置された複数の電池セル１４を、それらの側面２２０４を互いに平行に維持しかつそれらの側面２２０４の間に隙間を確保した状態で各電池セル１４を保持するものである。
底壁２８に設けられた仕切り板３２Ａは、電池セル１４のケース２０の高さの１／５よりも低い高さを有し、底壁２８の縦方向の全長にわたって延在している。したがって、仕切り板３２Ａは、底壁２８に載置された隣り合う電池セル１４の側面２２０４の底壁２８に沿って延びる辺である側面下部に当接しつつ側面２２０４の下部に沿って延在している。

次に、作用効果について説明する。
なお、電池セル１４の側面２２０４が膨らむ場合、側面２２０４の中央部が最も顕著に変位し、側面２２０４の周辺に至るにつれて変位が少ない。
メインテナンス時に、カバー４を外して、電池モジュール１２を視認する。
図３に示すように電池モジュール１２を上方から視認した場合、底壁２８に設けられた仕切り板３２Ａの上縁の蛍光部Ｐが視認できると、電池セル１４の側面２２０４が膨らんでいないと簡単に判断できる。
より詳細には、隣り合う電池セル１４の側面２２０４の中央部間において、仕切り板３２Ａの延在方向の中間部の上縁の蛍光部Ｐが視認できると、電池セル１４の側面２２０４が膨らんでいないと簡単に判断できる。
また、底壁２８に設けられた仕切り板３２Ａの上縁の蛍光部Ｐが視認できないと、電池セル１４の側面２２０４が膨らんでいると簡単に判断できる。 Next, operational effects will be described.
When the side surface 2204 of the battery cell 14 swells, the center portion of the side surface 2204 is most significantly displaced, and the displacement is less as it reaches the periphery of the side surface 2204.
During maintenance, the cover 4 is removed and the battery module 12 is visually recognized.
As shown in FIG. 3, when the battery module 12 is viewed from above, if the fluorescent part P on the upper edge of the partition plate 32 </ b> A provided on the bottom wall 28 is visible, it is easy if the side surface 2204 of the battery cell 14 does not swell. Can be judged.
More specifically, when the fluorescent portion P at the upper edge of the intermediate portion in the extending direction of the partition plate 32A is visible between the central portions of the side surfaces 2204 of adjacent battery cells 14, the side surface 2204 of the battery cells 14 swells. It can be easily judged that there is not.
Further, if the fluorescent portion P on the upper edge of the partition plate 32A provided on the bottom wall 28 cannot be visually recognized, it can be easily determined that the side surface 2204 of the battery cell 14 is swollen.

また、図４に示すように、窓３０１０を通して一方の第１側壁部３００２に設けられた仕切り板３２Ｂの先部の蛍光部Ｐが視認できると、電池セル１４の側面２２０４が膨らんでいないと簡単に判断できる。
より詳細には、窓３０１０を通して隣り合う電池セル１４の側面２２０４の中央部間において、仕切り板３２Ｂの先部の蛍光部Ｐが視認できると、電池セル１４の側面２２０４が膨らんでいないと簡単に判断できる。
あるいは、トレー１６の斜め上方から第１側壁部３００２に設けられた仕切り板３２Ｂの先部の蛍光部Ｐが視認できると、電池セル１４の側面２２０４が膨らんでいないと簡単に判断できる。
より詳細には、窓３０１０が設けられた第１側壁部３００２の上方から、隣り合う電池セル１４の側面２２０４の中央部間を通して、仕切り板３２Ｂの底壁２８寄りの箇所の蛍光部Ｐが視認できると、電池セル１４の側面２２０４が膨らんでいないと簡単に判断できる。
また、一方の第１側壁部３００２に設けられた仕切り板３２Ｂの先部の蛍光部Ｐが視認できないと、電池セル１４の側面２２０４が膨らんでいると簡単に判断できる。
したがって、第１の実施の形態では、電池モジュール１２を上方から視認しても、あるいは、窓３０１０を通して視認しても、あるいは、電池モジュール１２を斜め上方から視認しても、電池セル１４の側面２２０４の膨出の有無を簡単かつ確実に確認することができる。 Also, as shown in FIG. 4, if the fluorescent part P at the tip of the partition plate 32 </ b> B provided on one first side wall part 3002 can be seen through the window 3010, it is easy if the side surface 2204 of the battery cell 14 is not swollen. Can be judged.
More specifically, if the fluorescent portion P at the tip of the partition plate 32B is visible between the central portions of the side surfaces 2204 of the adjacent battery cells 14 through the window 3010, it is easy if the side surfaces 2204 of the battery cells 14 are not expanded. I can judge.
Alternatively, if the fluorescent portion P at the tip of the partition plate 32B provided on the first side wall 3002 can be visually recognized from obliquely above the tray 16, it can be easily determined that the side surface 2204 of the battery cell 14 is not expanded.
More specifically, the fluorescent part P at a position near the bottom wall 28 of the partition plate 32B is visually recognized from above the first side wall part 3002 provided with the window 3010 and between the central parts of the side surfaces 2204 of the adjacent battery cells 14. If it can, it can be easily judged that the side surface 2204 of the battery cell 14 is not expanded.
Further, if the fluorescent portion P at the tip of the partition plate 32B provided on the first side wall portion 3002 cannot be visually recognized, it can be easily determined that the side surface 2204 of the battery cell 14 is swollen.
Therefore, in the first embodiment, even if the battery module 12 is viewed from above, viewed through the window 3010, or viewed from the diagonally upper side, the side surface of the battery cell 14 is displayed. The presence or absence of the bulge 2204 can be easily and reliably confirmed.

この場合、蛍光部Ｐの色を電池セル１４の側面２２０４の色と異なる色とすると、隣合う電池セル１４の側面２２０４間の隙間を通して蛍光部Ｐが見易くなり、電池セル１４の側面２２０４の膨出の有無を確認する上で有利となる。
また、蛍光部Ｐの色を、電池セル１４の側面２２０４の色と補色の関係にある色とすると、隣合う電池セル１４の側面２２０４間の隙間を通して蛍光部Ｐが見易くなり、電池セル１４の側面２２０４の膨出の有無を確認する上で有利となる。 In this case, if the color of the fluorescent part P is different from the color of the side surface 2204 of the battery cell 14, the fluorescent part P becomes easy to see through the gap between the side surfaces 2204 of the adjacent battery cells 14, and the side surface 2204 of the battery cell 14 expands. This is advantageous in confirming the presence or absence of the ejection.
If the color of the fluorescent part P is a color complementary to the color of the side surface 2204 of the battery cell 14, the fluorescent part P becomes easy to see through the gap between the side surfaces 2204 of the adjacent battery cells 14. This is advantageous in confirming whether the side surface 2204 is bulged.
