Title: BATTERY PACK FOR MOUNTING ON VEHICLE
Abstract:
[Problem] The purpose of the present invention is to provide a battery pack for mounting on a vehicle, with which it is possible to inhibit the upper part of a pack case from reaching a high temperature when a gas is discharged from a unit cell. [Solution] A battery pack 10 for mounting on a vehicle, having: battery modules 100, in which specific surfaces of a module case 120 are set to be gas release surfaces 140 for releasing gas discharged from a unit cell; and a pack case 200 for housing the battery modules. The battery pack has a restricting plate 400 for inhibiting the gas released from the gas release surfaces from directly rising towards the upper part in the pack case. The battery modules are housed so that gas release surfaces face the inner surface of side wall parts of the pack case across a void part. The restricting plate has: a first plate part 410 projecting towards the side wall parts at a height position higher than at least the upper edge 143 of the gas release surfaces; and a second plate part 420, which is continuous from the projection-direction distal edge 411 of the first plate part, and which extends downwards in the void part.
