Abstract: A battery module includes: cells; and a battery holder made of a resin material that contains a filler in a resin matrix. In the resin material of the battery holder, the lower limit of the content of the filler is determined on the basis of the endothermic amount, and the upper limit of the content of the filler is determined on the basis of the viscosity. Another battery module includes: cells; and a battery holder having a plurality of tubular first accommodation portions each having a substantially hexagonal hole and a plurality of tubular second accommodation portions each having a substantially polygonal (heptagonal or more) hole. In the battery holder, the first accommodation portions and second accommodation portions are arranged in a manner of log pile by sandwiching a first column including the first accommodation portions between second columns including the second accommodation portions.

Abstract: A battery module includes a battery assembly and a thermally-conductive member to hold or support battery assembly. The battery assembly has a plurality of first batteries and a plurality of second batteries that are alternately stacked. The thermally-conductive member includes a first component and a second component that are each disposed along a stacking direction of the batteries. The first component has a heat resistance to the second batteries higher than to the first batteries. The second component has a heat resistance to the first batteries higher than to the second batteries.

Abstract: A battery module includes: a case body for storing a plurality of cells each having an exhaust gas valve; an exhaust passage for releasing, to the outside of the case body, the high-pressure and high-temperature exhaust gas having come from the cells; and a flow route changing unit that is disposed in the exhaust passage, has a hole for passing the exhaust gas, and elongates the flow route of the exhaust gas from the upstream side to the downstream side of the exhaust passage by changing the flow direction of the exhaust gas a plurality of times in a zigzag manner along at least one of the width and height directions of the exhaust passage. The flow route changing unit includes a plurality of flat plates each having a hole for passing the exhaust gas.
