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.

Battery pack including separator between secondary batteries

Each of the plurality of battery heat radiation units includes, a battery module, at least one heat pipe thermally connected at a first end of the heat pipe to one surface of the battery module and protruding from the battery module at a second end of the heat pipe, at least one metal heat exchanger plate thermally connected to one surface of the battery module, and at least one heat radiation portion provided at the second end of the heat pipe, the air blowing portion blows air to the heat radiation portion, and one heat radiation portion in the plurality of battery heat radiation units is misaligned with other heat radiation portions in the plurality of battery heat radiation units as viewed from the air blowing portion side.

Battery heat radiation system, battery heat radiation unit

According to one embodiment, a battery unit includes a first cell unit, a second cell unit and a third cell unit arranged adjacent to the first cell unit, respectively. Each cell unit includes a plurality of secondary battery cells, and the respective secondary battery cells are formed of a main body of a substantially rectangular solid shape and a pair of first and second electrodes of different polarities each other pulled out from one end of the main body. A first bus bar connects the first electrodes of the first cell unit and the second electrodes of the second cell unit in a first line, and a second bus bar connects the second electrodes of the first cell unit and the first electrodes of the third cell unit in a second line.

Battery unit and secondary battery assembly equipped with the battery unit

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 holesand connector pinsthat configure a large current charging connector part are disposed in the vicinity of both ends of the power supply connector. There are disposed a plug insertion holeand low current charging connector pinsthat configure a low current charging connector part held between the insertion holesand the connector pins
