摘要:
The present invention is a power storage device including a holding member holding power storage units and temperature detection sensors detecting temperatures of the power storage units held by the holding member, in which the holding member includes a facing surface portion facing coated surfaces of the power storage units held by the holding member, and through holes formed so as to pierce through the facing surface portion, each of the temperature detection sensors includes a lid unit closing the through hole by being attached to the holding member, and a sensor unit supported in the lid unit so as to be elastically deformed, which is elastically deformed when the lid unit closes the through hole, pressed and contacted onto the coated surface of the power storage unit due to reaction force of elastic deformation.

A cell block includes holding sections that hold a battery cell arrayed body of a lower layer between a lower holding frame member and a middle holding frame member, hold a battery cell arrayed body of an upper layer between the middle holding frame member and an upper holding frame member, and hold the battery cell arrayed body of the upper layer and the battery cell arrayed body of the lower layer in a state displaced from each other in the row direction. Lower fastening sections are disposed at positions below a battery cell and projects in the row direction beyond the battery cell arrayed body of the lower layer, and join the lower holding frame member and the middle holding frame member with each other by fastening.

A secondary battery module 1 of the present invention stores cell blocks 40 in a module case 2, and cools battery cells 101 in the cell blocks 40 by circulating coolant to the inside of the cell blocks by introduction of the coolant into the module case 2. The secondary battery module has a structure of communicating coolant circulation ports 22 that open to a case wall section 21 of the module case 2 and coolant circulation ports 62a that open to the cell blocks 40 with each other by a communication member 71, and passing wiring through a space region 80 formed outside the communication member 71 and between the case wall section 21 and the cell blocks 40. Thus, wiring can be executed without interfering flow of the coolant, and the total secondary battery module 1 can be miniaturized.

A battery module with an excellent cooling effect includes a battery unit 194 and a circuit unit 192. The battery unit 194 includes a casing main body 195 having an external frame 195a formed of a plate-like member in a rectangular shape and an internal member 197 supported inside the external frame 195a. A plurality of lithium single cells 202 to 208 are connected in series to form a longitudinal tandem cell 200. A plurality of the tandem cells 200 are disposed on either side of the internal member in parallel, and the entire tandem cells are connected in series by connecting metal fittings that are disposed on either side of the tandem cells 200. A cover 198 with ventilation opening is mounted on the casing main body 195. The circuit unit 192 is disposed on one end of the battery unit 194 and includes a control circuit that detects the voltage of each of the lithium single cells 202 to 208 and transmits the result of detection using a control means.
