Abstract: A battery includes a plurality of secondary batteries, a casing including a lower case and an upper case, and a plurality of separators interposed between corresponding secondary batteries. Each separator includes a first stopper in a lower part, a second stopper in an upper part, and a cooling passage between the secondary batteries and between the first stopper and the second stopper. The casing includes a face opposing the lateral faces of the secondary battery and including an opening opposing the cooling passage.

Abstract: A power supply connector is provided, which is applicable to both large current charging and low current charging, the power supply connector being able to not only maintain the accuracy of monitoring low current charging and the volumetric efficiency of a board by appropriately arranging two types of connector parts, but also contribute to the downsizing of the power supply connector and improvement of the reliability thereof by striking a balance between the volumetric efficiency and the heat radiation characteristics, and ensure safety in the use of the power supply connector while reducing the cost. Insertion holes 4 and connector pins 2 that configure a large current charging connector part are disposed in the vicinity of both ends of the power supply connector 1. There are disposed a plug insertion hole 9 and low current charging connector pins 11 that configure a low current charging connector part held between the insertion holes 4 and the connector pins 2.

Abstract: A battery pack is provided, in which external connection terminals are arrayed in the same direction in the module having the plurality of cells connected in series and a wiring that cuts across the module is not generated, and, in which improvement of the workability and reduction of connection failures are achieved by only connecting between the units by means of a bus bar when creating the module. Three pieces of flat-plate cells 2a to 2c are arranged in parallel to configure a three-piece unit 1. A positive electrode terminal 3 and negative electrode terminal 4 are provided at the top of each of the cells 2a to 2c.

Abstract: There is provided a bus bar which electrically connects two terminals respectively provided to two batteries with each other and is formed of at least one tabular conductor, the bus bar including two connecting portions which are connected with the two terminals, and a convex portion formed into a convex shape between the two connecting portions by curving the tabular conductor.
