PROTECTION STRUCTURE OF BATTERY PACK

PROBLEM TO BE SOLVED: To provide a protection structure of a battery pack in which, when the external force is added to a vehicle body, impact can be inhibited from being added to a battery case and the battery pack can be easily protected.SOLUTION: In a protection structure of a battery pack 11, a protective cover 18 includes: an upper surface cover part 19 for covering the upper surface of an upper case 16; and a side surface cover part 20 which protrudes outward than the side surface of the battery case with respect to the upper surface cover part 19 and covers at least a part of the side surface of the battery case. A fragile part 19A is formed in the upper surface cover part 19, and when the external force is added to the side surface cover part 20 from the direction in which the upper surface cover part 19 and the side surface cover part 20 are arrayed, the upper surface cover part 19 is bent or ruptured using the fragile part 19A as a starting point.SELECTED DRAWING: Figure 6 【課題】車体に外力が加わった場合に、バッテリケースに衝撃が加わることを抑制することができ、バッテリパックを容易に保護することができるバッテリパックの保護構造を提供すること。【解決手段】バッテリパック１１の保護構造において、保護カバー１８は、アッパケース１６の上面を覆う上面カバー部１９と、上面カバー部１９に対してバッテリケースの側面よりも外方に突出し、バッテリケースの側方の少なくとも一部を覆う側面カバー部２０とを有する。上面カバー部１９に脆弱部１９Ａが形成されており、上面カバー部１９と側面カバー部２０とが並んだ方向から側面カバー部２０に外力が加わった場合に、脆弱部１９Ａを起点にして上面カバー部１９が折れ曲がる、または破断する。【選択図】図６
